Thanks for the feedback. the full chisel blog is cool.Like the press he made too.
I used ash and hickory. Hickory for the horizontal as it needs to support the weights.
It does get the job done and may save my wrist for a few more years. I use it before chopping out a mortise so accuracy is not a huge deal. Just need to clear the wood. I wouldn't use this method if I needed a more accurate hole.
Two issues:
1. I incorporated a wooden clamp for easy "on off" application. ie I screw it to the bench top. Those are not that robust. Make this union snug to avoid lateral wobble...or make a different clamp.
2. As you are drilling a hole the cross beam is not "horizontal". I carved out a rounded cup to accept the brace head. Leather to protect it. Works ok but mine will occasionally slip out and gravity pulls the weigh down... make a deeper cup that will accept the changing angle of the brace as you drill.
This larger lathe was going to be a fly wheel treadle type. I am looking for an excuse to steam bend and thought I would start with an overhead bow like the chair bodger from Paintlick,Ky...Don Weber. Still considering the use of a bike gear to create continuous forward motion vs reciprocol motion. He has done that too. Would be nice to have more than one mech as a back up.
Ultimately might add a frame saw as an accessory...but can only fight one war at a time.
I'll keep you posted.
cheers
