I generally get up a little before dawn and just for the heck of it I went outside not long after sunrise and found our roses covered in frost and got these photos before it melted. Just cell phone images because by the time I’d have got in the house, got out the good camera and got back out the frost would have melted. These aren’t as good as they could have been I suppose, but I like them. You should be able to click or double click on the images to see a better resolution version.
Oh, the excited part? Once you scroll down past the photos I’ll tell you about that.
There’s a lesson to be learned here for amateur photographers. You don’t need to go traveling to exotic places to get really interesting photos. Just look around in your backyard.
Now, the fun part. One thing I’ve done for years now is fiddle around with 3D printing. I’ve had a Flashforge Creator Pro 3D printer for years now, although my son has had it for some time using it to print parts for a laser engraver/cutter and other stuff.
I’m getting a new printer, the brand new Flashforge Adventurer 4 that just hit the market this fall. Flashforge came out with the Adventurer 3 shortly before this one came out and this is basically the same thing only with about twice the build capacity as the 3 version. I’m really looking forward to getting my hands on this one.
This is supposed to be a more or less ‘turnkey’ printer, just unpack it, put in the filament and start printing right out of the box. The extruder can also operate at a wider range of temperatures meaning it can use just about any type of filament on the market. I liked my old Flashforge a lot but it is definitely showing its age and its inability to work at the higher temperatures that some types of filaments require limited it to using only ABS and PLA. The print quality of this thing is supposed to be outstanding from the preliminary information I’ve dug up.
Supposedly there are some issues with things like WiFi connectivity and cloud access. Neither of which I care about in the slightest. I don’t want a printer connected to the “cloud” in the first place and my preferred method of getting files to the printer is via a flash drive, not over the network.
Anyway, this puppy is supposed to be here within the next seven to ten days so keep an eye out for that in the future.
Yes, a Christmas rose! It was a beautiful sunny Christmas morning here, if a bit cold out, I walked over to the window and saw this. One of two new budding roses on that goofy little rose bush that started out life as a $5 teacup rose I bought on impulse for MrsGF a few years ago. Roses blooming in Wisconsin on Dec. 25? Hey, I’m not going to complain. It was an unexpected and amazingly beautiful Christmas gift.
Her Christmas cactus is being equally fruitful. It has been in full blossom since October and is still going.
Anyway, let’s get on with this…
Wow people must be bored out there because people have actually been emailing questions to me (email@example.com is how you can get in touch with me but be warned I do not check this email account more than once a week or two. If you want a fast response the best way is to just leave a comment). So I’m going to talk about some of the questions I’ve received over the last few weeks.
First someone told me they heard that KFC was coming out with its own gaming console. Yeah, right, I thought. Sure it is… Only, yeah, they are.
There it is, folks, the Kentucky Fried Chicken’s gaming console. KFC is supposedly coming out with its very own video game console, completely with a special warming unit to keep your chicken warm while you, oh, blow up aliens or something. And yes, it’s real. At least according to Snopes. Supposedly there is a special rack inside of this thing that uses the heat generated from the electronics to keep your nuggets or whatever warm.
At first I thought this was the stupidest thing I’d ever heard of, but then I thought, well, why the heck not? Yes, it’s silly and utterly ridiculous, but we need something that’s ridiculous and fun and silly to take our minds off what’s going on out in the real world right now. So go for it. Heck, if it isn’t too expensive when (if) it comes out I might buy one.
So let’s talk about sanding next. A couple of writers mentioned in emails to me there are some people out there, especially woodturners, who get a bit, well, weird shall we say, when it comes to sanding. Both of them turned my attention to YouTube videos showing woodturners going to extraordinary, even ridiculous lengths, like sanding a bit of wood to 1,000 grit or even higher, in one case wet sanding at 4,000 grit. Then using all kinds of exotic polishing abrasive pastes and, well, it’s just ridiculous. Yes, I understand they want a lovely, high gloss finish on their finished product. But a lot of what they’re doing is a complete waste of time and money.
Look at these two bowls. Both of these have a beautiful, very high gloss shine on them. And if you could run your fingers over them you’d feel that both are as smooth as glass. Even the one on the left with all of it’s bark inclusions and peculiar grain structure is like that. Both of those bowls were only sanded up to 240 grit. That’s it. No special expensive and exotic polishing abrasives, no wet sanding at 1,000 grit. No fancy tools or anything else. Just plain old sandpaper starting at 80 grit and working up to 240. And no fancy, expensive, difficult to apply finishes, either. One has nothing but OB shine juice on it and the other is carnauba wax over the top of shellac sealer.
Yes, I might have gotten a bit better finish if I’d gone up to 400 grit when I was sanding, but after a while you reach the point of diminishing returns. The effort and expense doesn’t justify the end result. I look at this the same way I look at sharpening tools. There is such a thing as “good enough”. Yes my chisels might cut slightly better if I went to the trouble of putting a mirror finish on them, but not that much better. And that slight improvement is going to be lost after making a few cuts anyway. I know that from experience. So what’s the point? I feel the same way about sanding. Yes, if someone examines one of those bowls up close with a magnifier they’ll probably see some very fine scratches. But so what? People aren’t going to be taking out a jeweler’s loupe or magnifying glass to look for every defect they can find. They’re going to be looking at that bowl from a distance of several feet. Even if they pick it up they aren’t going to see a problem. So why go to the additional work and expense of carrying things farther?
Of course there are exceptions. There always are. I’ve been talking about wood. When it comes to resin things are different. Resin is great fun to work with, but it presents its own unique challenges. One of my first resin experiments is over there on the left. The end result doesn’t look too bad, but lordy did I have problems getting it to that point because, frankly, I had no idea what the heck I was doing when I started messing with this stuff. I had to do considerably more work to get this little lamp smooth and scratch free, but in the end I still didn’t have to go to the extremes I’ve seen people go to on YouTube. This one was sanded to much higher grit than my wood projects, but only to 600 grit. And I did use a final abrasive paste/polish before putting a finish on it. But that’s it. I didn’t sand it up to 1,000 grit or more, didn’t wet sand it, didn’t do anything extraordinary. The wood parts were treated with my usual sealer, and the whole thing was topped off with a buffed coat of carnauba wax.
All of this only applies to woodturning, of course. If you’re working with flat surfaces like furniture you may want to go with an entirely different approach, which is to not do sanding at all. I rarely resort to sandpaper with my furniture. I use cabinet scrapers. Once I learned about these and how to properly use them, I found out that if used properly you can often get away with not needing to sand a flat wooden surface at all before applying the finish. These things have saved me hours of sanding, and it’s well worth the effort to learn how to use and sharpen them. Here’s a short video explaining what they are and how to use them.
Getting the proper burr on the edge isn’t a big deal, either. You can do it by hand but I use one of these things over there on the right. It’s from Veritas and it will put the proper burr on a scraper in just a few seconds.
How well do they work? Well look at that table down below. I made that, oh, must be 20 years ago now. It could probably use some refinishing about now, but considering how old it is and that it has survived two teenaged boys and their friends, a rambunctious golden retriever and several crazed pussy cats, it’s held up pretty well. And except for the curved edges, none of that wood was touched by sandpaper. It was prepped for finish with just cabinet scrapers.
Of course it all depends on the “look” you’re trying to achieve. Personally I like wood that looks and feels like wood. I think wood is beautiful all on its own and doesn’t need much to make it look better. And on my furniture I want people to not just see that beautiful grain, but to feel it, too. My stuff is made to be used, to be touched, and to be lived with. I don’t like these high gloss, glass smooth finishes that a lot of people put on furniture. I think it makes it look like plastic, not real.
Anyway, that’s my two cents on that. Remember that there is such a thing as “good enough”, and once you reach that point, seriously think about whether it is worth the effort to go farther.
And to wrap this up, here’s a violet in the early Christmas morning sun.
Someone asked what kind of wax and finish I’ve started using recently so here’s a bit more info.
The basic formula for the sanding sealer I use is one ounce (weight, not volume) of shellac flakes to one cup of denatured alcohol. Put the flakes into a glass jar that has a tight fitting lid. Add one cup of denatured alcohol. Give it a stir, put on the lid and let it sit for at least 24 hours. If there is still undissolved shellac at the bottom of the jar after 24 hours, give it a gentle shake and let it sit another 12 hours. By that time everything should have dissolved. Once it’s dissolved, pour it through a coffee filter into a clean jar and put an air tight lid on it, and it’s ready to use. It will be pretty thin. That’s ok because for this application I don’t want a thick product. You can make different “cuts”, i.e. concentrations, of shellac for different purposes. It’s pretty useful stuff for a woodworker. If you make it yourself it’s of better quality than the pre-made stuff you get at the home improvement stores. I am not sure how long of a shelf life it has, to be honest. I’d think that as long as you have it in an airtight container it should last for months.
I use it mostly as a sealer. I figured out (I think at least) that the reason the beeswax/tung oil finish was looking so poor after a couple of months was that it was being absorbed into the unsealed wood. Maybe. I do know that after I started putting on the sealer before the final finishes the projects look much better and doesn’t seem to degrade over time.
I use a disposable brush to put a thin coat on the raw wood after it’s been sanded. Don’t load up the brush and really slather it on, use just enough to cover the wood. A lot of it will absorb into the wood, especially on end grain, so I put on 2-3 thin coats. Then I buff it lightly with #OOOO steel wool. Wipe it down with a clean cloth and look for any imperfections or problem and sand and apply another coat if needed.
This is what walnut looks like after three coats of the shellac has been applied.
Now you could just buff this out as-is, maybe put on a thicker cut or more coats as necessary to get a nice finish. Shellac makes a perfectly good wood finish all by itself and has an advantage in that it is repairable. You can just apply another coat, the alcohol will dissolve the existing shellac and it will all blend together. But shellac is fairly easy to damage and I want something a bit more durable and harder, so I’ve started using carnauba wax.
Carnauba is interesting stuff. It’s made from the leaves of a palm tree from South America. The stuff is incredibly useful. Go look it up over at Wikipedia if you want to know more.
I learned an interesting trick for applying the wax from watching videos on Youtube. I buy solid carnauba formed into a bar about the size of a candy bar. I spin the bowl or whatever on the lathe at about medium speed and press the bar against the spinning bowl.
This leaves a deposit of wax on the bowl. Then I turn up the speed on the lathe and buff it out with a clean cloth.
That generates enough friction to heat the wax up and melt it, leaving behind a nice, glossy surface.
As far as I’m concerned, there are a lot of advantages to this. It doesn’t take long to do. The shellac dries pretty quickly so I generally just leave the piece on the lathe during the whole process. It only takes a few minutes to apply a coat of the wax. The resulting finish looks pretty darn nice. And it seems to be pretty durable as well. Best of all there are no harsh or harmful chemicals in this stuff. Shellac and carnauba wax are both so safe they’re used as food ingredients. The alcohol evaporates within a few minutes. Some caution is necessary because of alcohol fumes, but that stuff is heck of a lot safer to use than many of the additives they put into commercial finishes.
It’s also reasonably cheap. That bar of wax cost me about $13 and it looks like it will last me a year or longer. It takes very little to cover a bowl. That 1 lb bag of shellac flakes cost me about $30. At the rate I’m using it that bag will last me over a year as well. The actual cost of the shellac works out to about $1.87 of shellac flakes per cup of liquid product at the rate I use it. Denatured alcohol sets me back $35/gallon, or $2.18 per cup. Rounding everything off, it costs me about $4 per 8 oz cup to make the liquid shellac I use. Now I could get commercially premade stuff for about that cost or even a bit less than that, but this way I know exactly what’s in the product I’m using. I don’t have to be afraid of some kind of weird chemicals being in the stuff that could be potentially harmful. Some commercial producers throw in additives to extend the shelf life because that can could be sitting on the shelf in a store for years before someone buys it. They also add coloring agents, chemicals to control evaporation rates and I don’t know what all else. And the quality seems much better than what I’ve bought commercially.
It does slightly alter the color of the wood, however. The lightest grade of shellac will add a sort of golden tone to woods, especially lighter colored woods. It generally isn’t all that noticeable, though. It is available in different colors that range into a deep, reddish brown.
Rikon Band Saw
I mentioned a week or so ago that I bought this. So far it looks like it’s a pretty nice saw, but it’s early days yet. I bought it from Amazon. It arrived well packed in a single big box weighing around 80 lbs. I had to use a handcart to get the thing down into the workshop. It does not come with a stand so I had to spend another $50 to get a stand for it. It went together pretty easily. It took longer to put the stand together than it took to put the saw together. The saw comes with all of the tools needed to put it together except for a screwdriver. The only thing I had to put on the saw was the table and a few bits and pieces, and do basic setup of the blade guides. The blade was pre-installed. Installing the table was a bit fiddly, and I think I’ll need to get in there and do a bit of fine tuning to get everything perfectly square.
So far it looks like a really nice saw. I’ve wanted one of these for a long time and it is already proving itself to be one of the more useful tools I have in the shop.
To be honest I didn’t really expect much from a bandsaw in this price range. I paid $430 for the Rikon and I assumed that despite the glowing reviews it would be under powered, be flimsy and have problems. I was wrong. Build quality seems to generally be excellent. The motor hasn’t bogged down even when cutting 4+ inch thick stock. Dust collection isn’t as good as I’d like it to be but even there it isn’t horrible. It does a good job cutting curves and circles.
It does have some minor issues that aren’t deal killers. They claim it has a full 5″ cutting capacity. It’s actually a bit less than that. It seems rather noisy when cutting, but I don’t have a lot of experience with bandsaws so this might be normal. I’m a bit concerned about the amount of sawdust that accumulates on the lower blade guides as shown in the photo up there. The fence is, well, a basic fence that pretty much works, but I’d have liked one a bit more sturdy. Still, at this price I should be grateful it comes with a useable fence at all.
Let’s see, what else is going on- oh, I have a new resin piece sitting in the pressure pot that should be coming out in 2 days. I’m using up some scrap wood and am going to try to make a small decorative lamp. I picked up some small LED lamp inserts with in-line switches for about $7 each that look like they should work. So we’ll see how that goes once the resin is cured and I get it out of the pot. I figure it will take at least 2 – 3 days for it to cure.
The weather has been, well, this is Wisconsin. The weather here is always a bit strange. I remember days when we literally had snow storms in the middle of May. In the last week we went from winter like conditions where the temperatures never got above 35 degrees and one or two snow falls, to temperatures now up in the mid to high sixties.
Not much is going on out in the gardens. MrsGF got bored yesterday and did some more cleanup in the gardens, but other than that most gardening stuff is going to be on hold until late winter when we start planning what to grow. And somehow that dopey rose bush in front of the house is still in flower.
I don’t know how this thing does it. After days of temperatures under 35 degrees, dipping down to about 20 at night, this thing is still flowering?
I picked up a really nice piece of ambrosia maple and I’m trying to figure out what to do with that. It looks like a really interesting piece of wood. The problem is it’s green. My moisture meter says it’s up about 35% moisture. That means I can’t just start whacking away at it. I’ll have to work it down into a rough shape and then let it sit and dry for a few weeks before I can actually finish it up.
A lot of wood turners love working with green wood because it is a lot easier to rough into shape on the lathe. I think these people are silly. Working with dry wood is, in my personal experience, not that much more difficult than working with the green stuff if your tools are sharp and you’re using the right techniques. I like to think I’m a patient person, but sitting around waiting weeks or even months for a green bowl blank to dry down? No thanks. Plus green wood warps, cracks and checks as it dries down and I’ve ended up with nice pieces of wood being tossed onto the scrap pile. So I’d much, much rather work with dry wood than green.
Apparently Mother Nature wasn’t satisfied with deluging us with snow a month early, now she’s trying to freeze us with temperatures we usually don’t see until well into January. It’s about 3 degrees (F) out there, with windchills down in the -10 range. Sheesh…
Meanwhile, MrsGF has this growing in the living room. Just took these photos the other day-
Yeah, roses. I’ve put up photos of this before, but I figured this plant would go dormant or something by now. But it just keeps right on blooming.
This thing started out as one of those goofy little teacup roses, a tiny plant in a cheap cup that they sell for a few bucks on Mother’s Day or Valentine’s Day. Think I paid all of $7 for it, oh, must be at least two or three years ago. And after we got sick of it sitting around the house MrsGF said what the heck, let’s put it in a big pot and see what happens and the dopey thing just kept growing and flowering. We were putting it in the basement, letting it go dormant over winter, but this year she thought she’d put it in the living room where it could get some light and keep watering it, and well, it apparently likes it there, and it’s been flowering on a regular basis all winter so far.
I asked her how she’s keeping it flowering and she swears she’s just watering it and isn’t doing anything else. Personally I figure witchcraft is involved.
The MagLoop Antenna
I talked about this antenna before, and I continue to be more than pleased with it. Since my dipole came down in the last snowstorm it’s been the main antenna for my TS-990, sitting on the floor behind me in the office. And it is doing ridiculously good.
The Great Radio Fiasco Project
I mentioned this before, but let me summarize what I’m trying to do here. For reasons I won’t get into right now, I challenged myself to build, from scratch, a decent radio receiver, preferably shortwave. Emphasis on the word “decent” because I could throw together a few parts and end up with – well, with something that would receive, well, something that might be a radio signal, and pump it into a speaker and you’d hear some sound that might be interpreted as a radio transmission by someone with bad hearing. It could technically be called a radio receiver, but, well, let’s face it, it wouldn’t exactly be useful.
When I first conceived of this project I was like how hard can this be? In those WWII movies the Resistance throws together a radio out of bits of string, a piece of wire, an old cigar box and bits off a horse (don’t ask me what bits, I don’t know, ask them, they built the thing) and call up Churchill at Bomber Command and call in an air strike on Hitler’s outhouse. And the Good Ole Boys in amateur radio weep bitter tears of disappointment over the fact that modern day hams don’t build stuff any more like they did, when they’d throw together a 1,500 watt amplifier, transmitter and superhet receiver in an afternoon, out of parts they salvaged from old washing machines. And bits off a horse for all I know.
Here’s the thing, though – 95% of that (maybe even 98%) is pure BS. I’m sorry, but it just is.
The days of being able to salvage anything useful from discarded electronics are long gone. Modern SMD (surface mount devices) and robotic assembly methods make it virtually impossible to salvage anything useful from relatively modern equipment. And while you can buy discrete components like resistors, capacitors, etc. in the more common values, increasingly it is difficult to find a lot of stuff in anything but SMD form, and in quantities of 1,000 or more. I was trying to find what had once been a very common opamp the other day. It is still available. But if I want to get it from a US supplier I can only buy it in quantities of 1,000 or more, and in SMD format. If I want it in the traditional 6 pin IC form, and only want a few of them, it looks like I’m going to have to order it from China and it won’t get here until mid-March.
Nor are parts cheap. Oh, some are, true, but not the kind of stuff I’m looking for. A single variable capacitor I need for a project sells for $25. And I need two of them. So I’m going to have $50 stuck in that project before I even get started on it.
And then there’s the design of the equipment you want to build. If you were going to set out to build your own radio receiver, probably the first thing you’d do is fire up Google and look for something like “build your own radio” and find, well, hundreds and hundreds of hits that are utterly worthless, along with a few sites that might have actual plans to build something. Only most of those plans are for useless crystal radios and other nonsense. And the designs that do look useful are probably going to be wrong and no one is going to tell you how to fix it when you build it and it doesn’t work. In fact, most of the designs I saw out there were copies of stuff pulled out of old radio or electronics magazines from the 1960s or 70s that didn’t work in the first place.
(Sidenote: I’m convinced that the building plans in all those electronics magazines published in the 50s, 60s, 70s, etc. were never actually built by anyone because about six or eight months after the plans were published there’d be a “corrections” item pointing out that they forgot this part, or the wiring was wrong and if you’d actually build the thing it would have exploded, electrocuted your cat or something.)
So the question is, can I build a decent radio receiver from scratch? Probably. Will it work? Maybe. Can I do it for less than what it would cost to just go buy one? No way in hell. Will it work as good as even a cheap piece of junk commercial radio? Almost certainly not.
So why am I doing this? Uh, because I’m a stubborn old goat?
