  • 20 Watts, 20 Meters, and a Dipole

    20 Watts, 20 Meters, and a Dipole

    Since getting my license in 2024 I’ve spent most of my time on 10 meters. My only always-up antenna is a mag-mounted 10 meter vertical on my chimney. Occasionally I’ll setup my multi-band vertical out in the front yard and play around.

    Yesterday I decided to try making my own 20 meter, half-wave dipole. I used 16 gauge speaker wire, a BNC-to-banana binding post (plus various adapters I had on-hand), two insulators, and a pair of metal garden fence posts.

    This is the first time I’ve tried using something other than a purchased antenna and I’m certain it’s deployed sub-optimally. It is low to the ground, in a slightly sloping, inverted v configuration. To say I didn’t have my hopes up would be an understatement.

    Imagine my surprise to see this when I fired up FT8.

    And my transmissions were getting out well, too.

    I had no issues getting onto Single Side Band voice and making contacts around the country. In addition, I fired off an email using Winlink with Vara HF via a station several hundred miles away.

    So there we go. This was a low-effort attempt that was actually useful. I’m impressed.

  • Lathe Cat

    This was another fun lathe project. The body and head are turned separately, and the head attaches via a tenon on the body. This was made with some Honey Locust pieces I’ve had sitting on my shelf waiting for a purpose. It stands around 10″ tall.

    The ears are a turned cone which is then cut in half with a hand saw (or jigsaw). Each half is then carved with a rotary tool/Dremel.

    For the whiskers, I split small slices of leather. They were drooping so I dripped thin CA glue onto the leather to stiffen them up.

  • A Snowman or Two

    A Snowman or Two

    Small projects on the lathe are fun. For a little time in the shop, I can have something started and completed. And it’s a bonus when they can be actually used as decorations or given away.

    This year I tried my hand at a few snowmen – one small enough to be an ornament for the Christmas tree.

    These all have maple bodies. Four have walnut hats and one cherry hat. Buttons and noses are unknown wood.

    Here are a few photos of the process…

  • Santa Incense Smoker

    Santa Incense Smoker

    A huge thanks to Craft Supplies USA‘s commitment to teaching projects on the lathe. They released a video last month showing off how to use their German Smoker (incense) kit to make a fun little Christmas project.

    After plenty of rewinding, fast-forwarding, and otherwise studying the video, I was able to turn my own Santa Claus this weekend.

    At the part of the project where I was painting the face, I was incredibly skeptical that it was going to look good in the end. But once the hair, beard, and hat were added – I’m very happy with it!

    If you’re looking for a fun project for the holidays, give it a shot. You may just end up with a decoration you’ll pull out year after year.

  • More Sycamore

    More Sycamore

    Last week I processed a couple more of the rough turned Sycamore I mentioned in Log to Bowl, Wood Unknown. There are so many interesting grain patterns here, I’m a little sad I don’t have that many more pieces left.

  • Log to Bowl, Wood Unknown

    Log to Bowl, Wood Unknown

    Earlier this year I was able to get ahold of a few pieces of an unknown species of wood. I quickly rough turned them back in April and placed them in to paper bags with shavings to dry.

    Tonight I took one off the shelf, weighed it, and found it had stabilized. Ready to turn!

    There is a lot for the eye too look at, that’s for sure. There was a little tearout but not too bad. Polar water for scale 🙂

    I don’t know what kind of wood it is, so if you recognize it, let me know. Here’s what it looked like in log form.

    The new lathe is a pleasure to work on. Vibrations are greatly reduced and it simply does not bog down. It also has Reverse, which I’m finding very useful for sanding to a nice smooth surface.

    I have a few more of pieces of this wood and now I’m excited about what they’re going look like.

  • Skymo Radio Mount

    Skymo Radio Mount

    Facebook ads – yeah they work.

    Last week an advertisement popped up for a radio mount for my truck which caught my attention. It hangs from a cupholder and doesn’t require any drilling or modifications to the vehicle. For the past 8 months I’ve had my radio sitting in a less-than-ideal spot and previous searches didn’t reveal this option.

    It arrived yesterday and I was quick to get it installed. It’s perfect! It even works with a phone holder I have in the same cupholder. And no rattling!

    So if you’re looking for a non-invasive way to securly hold your radio, made specifically for your truck model, check them out. Skymo Radio Gear Company.

  • Dead Lathe; New Lathe

    Dead Lathe; New Lathe

    Last weekend I went to fire up the lathe to process some newly acquired logs and the lathe stopped lathing. Well, it spun but wasn’t happy about it. Lots of noise and heat, I just had to shut it down and say goodbye.

    Not thriled with the prospect of the cost of a full-size replacement (or getting one into the basement), I opted for another benchtop model. But this time I went with a Jet, one with a more powerful moter and about 60% heavier.

    Welcome to the Jet 1221VS!

  • RV Breaker Check Valve

    RV Breaker Check Valve

    We own a 2024 Forest River Shamrock 233s and recently encountered a problem I figured would be good to record a solution to.

    This year whenever I went to flush (clean) the black tank with the flush inlet, (clean!) water would start to flood the bathroom floor. We were in a rush to get packed up and checked out, so we cleaned it up and didn’t inspect it further.

    Fast forward to last week when we were on the road. In our downtime I did some reading and learned about the existence of the RV Vacuum Breaker Check Valve – specifically the cheap plastic version they put in campers which often breaks. And the symptoms were exactly what we were experiencing.

    This little thing sits up under the bathroom sink in the Shamrock (and Roo).

    I ran to the hardware store to quickly bypass it, with 1/2″ NPT nipple and elbow, just to get us temporarily up and running.

    Note – only do this as a temporary measure, and only when you’re using a separate hose to do the flush. Without the check valve, if the campground pressure were to drop, bad water and/or vapors could siphon backward into your fresh water.

    I then immediately ordered a non-plastic version, and installed it when we got home. Here’s to hoping we never have to think about this again.

    Here’s the one I purchased.

    As a side note, we had also recently noticed unwanted odors in the bathroom of late. I suspect this was the culprit.

    Hope this helps anyone else having that problem!

  • Bottle Opener

    Bottle Opener

    Last year I received some curly cherry wood. It’s been air drying and over this long weekend I decided to give a small piece a turn.

    It’s great looking grain, for sure. I’m glad I have several more pieces and will be looking to use it on nicer items in the future.

    As far as the shape goes, I messed up a little while turning so it’s about a half inch shorter than intended. I think a longer neck will more closely resemble a beer bottle.
