This is a bowl I turned from kiln-dried ash. I wanted to try something different, so I turned it three times on a faceplate (and yes, it was fairly badly unbalanced) to get the rough shape, then centered the faceplate and turned a mortise, then hollowed the bowl with that on a chuck.

There’s also a 1/16” drill bit left in the wood that you can see from where I was drilling one of my pilot holes for mounting the blank on the face plate. I couldn’t get it out, so I just left it and turned around it as best I could.

Unfortunately, with all the other excitement, I forgot to sand the bowl on the offset centers. This meant there was a lot of hand-sanding involved. If I figured my time at minimum wage, I would probably have to sell this bowl for four or five hundred dollars to “break even,” but I learned a lot along the way, so I guess it was worth it.

The bowl is about six inches across and two and a half inches tall. It’s finished with tung oil and shellac.

When you try turning with multiple centers, don’t start out putting the centers very far apart (these were a couple inches apart). Closer is easier. Less visually striking, but also has the lathe dancing around the shop a lot less.

thats the issue with a small midi lathe doing large turnings,lots of vibration.that bigger lathe may be closer in the future than i had planned. just dont tell swmbo-lol.

The 12-33 from Harbor Freight has been working pretty well for me. And this one didn’t scare me too much as long as I kept the RPMs down. Turning an awful lot of air, though.

Very nice. The off set turning & three lobes look great, nice work.

Thanks, Tom! As I mentioned to Pottz, I probably put the centers farther apart than I should’ve for my first offset turning, but it worked out.

Good work Dave! The shape came out very pleasing. “Turning an awful lot of air, though.” Haha, that’s the easy part ;-)

Thanks, Duck! The problem with turning air is that at some point, you run into wood, and if you managed to move the tool at all while turning air… well, it can be unpleasant. Good practice for a steady hand, though!

Thanks, Mads! I’ve seen a few YouTube videos of guys making tall and skinny bud vases. Looked easy enough when they did it, so why not try something flatter? Well, I learned quite a bit!

Thanks, Peter! Another trick in the bag!

Thanks, Oldrivers!

Jon, thanks, but I haven’t. I don’t mind the hand-sanding. It’s just a lot slower than sanding on the lathe. But a guy has to remember to do that at the appropriate time. So I got a lesson that will help me remember.

Steve, it was one of those “how hard could it be?” projects that I always learn a lot from.

Thanks!
