Using a offset jig in 3 jaw chuck

[La machinist]

I beveled this part using a jig. I turned chuck in reverse and used compound set at 45 deg. To cut on back side of part. Set screws hold material in place while cutting.

That is very cool. I would have never thought of doing it that way. Thank you for posting.

Is there a video on the process? My moving 3D imagination is not on top today ondering:

Sorry video was very short. Didn't want my supervisor to catch me playing on my phone. Lol

Neat technique! I'm still trying to get my head around the geometry of it though.:headscratch: :biggrin:

Thanks for posting it,

Nice! I was just thinking the other day on how one could face a miter on the lathe, (as in the one on the bottom of a fly cutter). I had concluded it could not be done that it would need to be milled. I quess you just proved me wrong. Nice work would sure like to here more about the set up, and what the off set needs to be. never saw this before. Mark

I think that if you use this method on a solid bar you will get an elliptical dome. I'm going to experiment with it tomorrow.

Please post the result - I'm thinking an eccentric cone, still straight sides and coming to a point.
