## Questions & Answers

**Q: What is the vertical distance from cutting tool tip to bottom of base?**
A: Over all 2.060" with 1.650 to the top of the base plate, 0.410" for base plate. Mounting holes are 0.325" and counter sunk 0.225"

**Q: Will this work on a Sherline lathe?**
A: its a little large and tall to fit a sherline but you may be able to thin down the base to get the centerlines to match up and fab a mount to fix it to your cross slide, its actually designed to fit a 7 inch swing or larger lathe

**Q: How use on my victor 2060 lathe**
A: The attachment is ok but I had to take time to make a custom mount to hold it at the correct height and adapt it to where my tool post usually sits .   The bearing is not perfectly tight , but it works good enough for my needs .  Took som time to make the mount work however . Good luck

**Q: Will it fit a harbor freight 7x10 mini lathe?**
A: In a word yes, but you will need to crate a way to mount it to the cross slide

### ⭐⭐⭐⭐⭐ Maximum of 1-5/8" diameter of your work piece!
*by K***. on March 11, 2025*

Works great for aluminum! Haven't tried stainless yet? That will be the real test!

### ⭐⭐⭐⭐⭐ Be prepared to modify this thing to fit your lathe
*by M***G on September 22, 2025*

Takes a little modification for it to work flawlessly, but it’s worth it

### ⭐ No scale included as shown, tool design and quality could be better.
*by D***P on November 10, 2021*

First issue I had was that this is not the one in the photo, and it did NOT have the scales it claimed, so I bought a metal ruler from HF and will rivet it in and make a pointer (this will probably be better than what's on the photo anyway). I have a job to do and can't wait for a return or refund. I dont like the way the handle attaches, it forces me to have the cutting tool on the back side of the work, but this is something a welder can fix. And last but not least, the pivot action is rough, but not terrible.
