A fellow motorcyclist and long time friend of mine is getting married, despite my ardent advice to run.

Since I’m obligated to provide some sort of item to mark the occasion, I decided to make something on the lathe.

Since both he and his fiancé ride, I wanted to make something motorcycling-related – but things turned on the lathe don’t have much practical use in that area… Or, at least, I couldn’t think of one.

After much deliberation, I settled upon a clock that resembled a rear sprocket, like this:

The idea is to cut sprocket teeth, and drape some old chain on it.

it may not be a great idea, but I like the combining of media (wood and chain), and it will have some connection to them – the chain is from when he and I replaced his chain about a year ago.

I had previously secured several (15 or so) pieces of what I think is basswood – they were used as bed slats, and were about 1/4×1 1/2”. I trimmed the rounded edges off with the bandsaw ( I don’t have a jointer), glued them into a plank, and had my cow-orker [sic], Core10, run it through his planer. I was left with a 1×8, about 2 1/2 feet long.

I cut off a piece, and put it on the lathe to do a little ‘test turning.’

That turned out to be rather exciting, as the glue failed and pieces of wood bounced around the shop/shed for what seemed like 30 seconds. Just when I thought it was over, another piece would land on the floor.

Fortunately, Core10 let me know about a local wood store. I stopped by there, and picked up a piece of maple – 8/4×8 x 12 – for $7.

I sliced off a piece, screwed a face plate on it, and got to turning.

At this point, I’ve gotten it to its final shape and have done the majority of the sanding. I’ve run through 80, 120, 180, 220, 320, and started on 440, but I seem to have been a little premature with the 440, as it exposed some deeper scratches.

I think I’ll leave those for after I get the sprocket teeth cut.

the pics are big, so they’re now a link to the originals

Sounds like a good idea for the present. Fits into both of their interests.

If I could make a suggestion, When putting pics in a blog, try to resize your pics a little smaller. They only show about 1/2 the pic in the blog if this big. Just a suggestion to make it easier to view.

Keep us posted on how it turns out.

That sounds like a great gift.
