Is this finish OK?

[fizzy]

Personally I think not or am I being too critical? Of course in photos everything comes out with high res!

Material is some sort of steel - I think pretty hard - didn't like being drilled.
Swarf comes off as little chips.

High speed around 750rpm and slowest feed.

Looks ok to me.

scotchbright is your friend when turning steels.

get a pack with course medium and fine and you’ll be good.

Looks like you have a bit of chatter in there. Reduce your tool stick out, make sure your gibbs are correctly set up, and try bigger cuts.

Looks like some mild chatter

Or cut isnt deep enough.

No chatter but a very fine cut.
I suppose with carbide needs to be deeper?

Need to give it something to cut.
Testing my inserts out
Excuse the thump. Motors changed now

Now that is a proper cut!
I have realised that whilst there is virtually no wear on the bed or anywhere else there is a bit of slack on the cross slide. Just A bit. I assume the bronze nut needs replacing. Under load I am guessing it is fine but under light loads perhaps not?

Carbide is rubbish at light cuts, best to work out your cuts in such way you are not taking light cuts

If you are going to take a light cut really sharp hss

Fed by hand then only had traverse away from the spindle at that point

Is there no adjustment for backlash.
There's a split in my nut with a dogpoint to remove backlash
Id rather a small amount of backlash than a worn nut thought
