Is that the tool that has a cutting edge with a large top rake and no front rake and is set for height so the middle of the front edge is set to centre height? Can you show a picture of the business end of that tool please

picture looks like a finish tool for a shaper with all the cutting done on the side of the tool in a shearing fashion in a very shallow cut.

One of those shear tools has been on my project list for quite awhile now. Glad to see it works so well on nasty steel.

Thanks for that. I vaguely remember the Chaski article all those years ago - I must get round to grinding one up and trying it for myself

Great posts you found Ed, thanks.
Dallen, the article I found it in was about shapers, I've used shearing tools on the shaper before but not on the lathe.
Free advice is worth exactly what you payed for it.

The messy braze job is probably 100 years old. You can see the end of my repair on top of the handle - the brown dot (a rag & bleach was used to add a little cosmetic rust). The same technique was used to fix a compound rest, before and after pics here. Basically using an adhesive (epoxy or loctite) and then "bolting" the halves together, followed by filing or machining the excess pin away. |
