If your suggest sandpaper, that means this doesn't need to be a precision surface, so I would try a very coarse file first Unlike sandpaper that will not shed abrasives all over the lathe. Mike

Use a very sharp tip carbide about 60° and a rake of 3° to 5°. Typically I would say C5 but for the project use C6 or C2 they very hard compared to C5. Note you may need to sharpen the tool bit a

A shear cut tool will leave you with a very fine surface finish. Bil in Boulder

That's an option too.Brian?

Maybe I shall cover everything and start with sanding paper? I am only interesting in a nice surface. The key slot shall stay there. Start testing to morrow! Johannes Lavoll.

I don't know what you have for tooling. I would try HSS first. The interrupted cut will probably chip carbide.?Brian?

Brian: this is solid steel, 3.5 kg, because of the key slot , it will vibrate. Slow speed , yes, but what tool? Johannes Lavoll.

If it fits, it's not too big. I turned some 2 or 2.5" tubing once.Brian?

Am I crazy? Too big for my 7x16? I need just to cut/grind/polish the outer surface so it looks nice. I think it has been a 2” axel , see the key slot. Weight 3.5 kg. High carbon steel ? I cut it

The DRO'S are great but they will skip I like them using on the carriage but not the cross-slide.? If DRO'S skip on a bearing bore you would scrap the part. I would use a dial indicator for

Here photo of two I use most. No errors Dave

That is why I dial indicators with 1 to 2 inch [25 to 50mm] stroke. It also takes care of DRO skipping too. Dave

DROs on dials don't take out backlash.? If you are thinking about DROs, attach them to fixed surfaces in order to get true readings. Ralphie

It is best to just get rid of those dial-based DROs. They are not as usful as the linear ones. The dail-based DROs don’t measure backlash I think the best solution for DRO power is wired.

I am just using the dials that came with my Speedway lathe that I bought 20 years ago. I have a 1-inch travel dial indicator that can be moved along the bed and a stop for the carriage that is
