At last had a little time in the shop. Way too hot outside. I copied this off of some other picture I saw on the web. But it's quick and dirty. I think it could be useful for setting the compound angle. All I had was structural steel for the plate, so I went ahead and painted it to cover up some deep rust pits, but it still works as far as function. The pictures explain it all.

I too was very impressed with the angle plate device you refer too, and have placed it at the top of my round tuit list.

Yes, thats the one I saw. It's a quick project out of what ever is laying around and easy to build.
More weird tools that the grandkids will never figure out:)

That will work great if you plan on running the spindle backwards.

Please explain why.

I guess Steve never needed to turn a taper which had the larger diameter toward the tailstock. Or (if the sine bar is flipped over) didn't need to turn long enough pieces with a "regular" taper at the end, so that the compound wouldn't hit the chuck. :)

It's only a ledge to rest the bar on, just reverse it end to end.
