« Part 21: Initial Trim and Inlay Part 22 of Of Tool Cabinets, Chewing Gum and Sealng Wax series Part 23: Cargo Style Pencil Box »

I had such great ideas for this swap. BTW if you have not joined a swap, you should – it will push your limits and you will learn a lot. First idea was a low rim open segment bowl with the openings filled with epoxy. Seemed like a good idea at the time. I didn’t do something right and it literally blew up. Good thing I had a jacket and face shield on. (I should show a picture, but it was too embarrassing, and I didn’t take one) After that disaster I made a small Movingui Salt bowl just to be sure I’d have something to ship if my next invention failed. Shown here in the hand of my recipient JD77 because I didn’t get a picture of it myself.

I had a couple of 3.5” x 3.5” Osage Orange chunks too small for much of anything but I figure if I spaced them and filled the gap with a metallic epoxy I’d have something interesting. Sealed the two pieces, mixed the epoxy and poured, waited a couple days and finally got it out of the “mold.” I glued a piece to the bottom to fit my chuck and started turning. Dang, chips and chunks of epoxy were flying off and hitting my face shield like rain. I did learn to lighten my cut and finally got it round (mostly).

After all the chips and chunks (I thought) I got the diameter down in what I intended to be a graceful curve. Hmmm… more chips and catches. Eventually I ended up with and kind of Bombay curve mostly because I was afraid of shattering the whole thing.

Finally finished the outside and tried to turn the inside. After a couple attempts I decided to just drill it our with a Forstner bit. Boy was that slow going. Cutting the end grain was tough. The bit would heat and gum up and the wood would toast. I spent almost as much time cooling and cleaning the bit as I did drilling. Here, I’m using a tool from another swap to gauge depth.

Finally made it to depth and wanted to thin the lip. Another bad idea – the whole sequence went MUCH better in my head, but caught an edge, flipped it off the lathe and onto the floor which chipped it.

Result? I had to trim off 3/8”. I finally knocked off the sacrificial piece on the bottom that allowed me to chuck the part.

With saw, file, and sandpaper I managed to get the lip where I wanted. Then I mixed a very thin epoxy to coat the inside and lip. That went VERY well and I did a second coat. The result is an OK (I think) Beer”Glass” that holds 8oz exactly and only by shear chance.

I think overall I learned a ton but I need to capitalize on techniques in the coming months.

For me, the projects that give me the most trouble are always the ones where I learn a bunch of things that make the next attempt go a lot smoother. Sounds like you had a good learning experience on this one, Bill!

Dave you are right! And while frustrating it was fun and I need to try it again soon. I saw in one of the Bowling posts that Epoxy dulls HSS. So that might have been part of my problem.

Is that a “Hairy” touchmark on that tool? He was my very first victim of a swap, back in 2019 maybe.

I’ll try the mug out tonight and let you know for sure, but it looks like it will hold up just fine.

LOL… why yes it is! And the mug comes with a 20/20 guarantee. 20 feet or 20 seconds and sad to say you’ve exceeded both ;-)

Yeah, epoxy dulls HSS real fast. Either use carbide or do a lot of sharpening. Also, shear-scraping is your friend. I was getting thin ribbons of epoxy coming off when I got it right, and that was pretty cool.

Happy to hear the beer glass survived, it looks awesome Bill, as well as the bowl.
