That's awesome, although it looks like something that would be excruciating to do with a non quick change tool post. I am mostly using insert tooling at this point although I have ground a couple HSS tools for special tasks. I'm mainly using the inserts because I am trying to keep grinding dust out of my shop to the extent possible. Something like you are doing, I would probably just try to get as close as possible with my parting tool, and then go at it with a file to try to smooth off the ridges. But your way is a lot more elegant.

Varnishing the wooden spars presented a bit of a problem: How to apply the varnish evenly to these cylinders. Because varnishing requires a wet edge while you work I couldn't varnish one side, flip them over, then varnish the other. That would leave a seam on each side - times seven coats would be fourteen seams on each spar. The millions of wooden spars on boats throughout history suggest this problem has been solved before, but I didn't know how.

Fishing fly tyers have a solution, though. For about $75 you can get a gizmo that will slowly rotate flies with epoxy heads while the epoxy hardens - so the epoxy doesn't all sag to one side. The pricing seemed a bit steep, especially as I'd need three.

Amazon to the rescue: They were happy to sell me three disco ball motors for $15 each.

A simple nail in a V-block held up the other end of the spars. I ended up cutting off the nail heads.

Anyone remember disco? Time for a spar varnish party!

The setup worked well. The motors turn at 6 RPM, which is a nice speed for this application. I turned the motors off for hand sanding, turning them back on again for vacuuming, wiping down the spars & varnishing. At 10 seconds per rotation keeping a wet edge was a snap. If I got the varnish a little heavy in spots it couldn't sag or run as there was no "down".

Here are the varnished spars:

That is one slick idea and the results are amazing!
