Dead simple lathe tool height gauge

[DanLins]

My only problem with this height gage is that while it might work fine with Marv's rotating tool post, it will not save time with the quick change type post, since rotating it over the cross slide each time to check it will cause position change on your tool holders, unless you can somehow get it back to the exact same point it was at before the rotation. On the other hand, setting it with the QCTP while aligned to the work piece will allow multiple removal and reinsertion cycles with the actual tool holder while maintaining accurate height and position.

Other than that, I liked your simple center finder so much I went ahead and made one for my lathe. Thanks, Marv !

I made up one of these some time ago from U tuber Joe Pieczynski It has been quite useful
I also use it to line up my dial indicators with 8mm and 0.3125" mounting shafts to set up on the center line.very handy for checking tapers and run outs.

Personally I've never used a height gauge. I always found it easier to write on tailstock the exact centre height to a fixed point on compound than just use a vernier to set tool. The cheap Chinese lathe I have is 3.495" to centre. I don't like the amount of overhang a QCTP gives small less rigid machine so use 4 way with shims. It's simpler to fit, find height and add shims to get exact centre

Thanks for posting your Lathe Tool Height gage Marv.! Simple is king!
I also use a simple two step lathe tool height gage. I have one step set for upside down tools on a rear toolpost and one set for use with standard a tool post.
