Hey guys - I know a lot of people are going to say "You need a bigger more rigid machine" and thats ok, but I actually enjoy having a small guy because it doesn't take up much room and I can do 99% of the work I want on it. Anyhow, I made some bushings and stuff that I really want a better surface finish on.

Here you see a stainless rod I turned down - it was to be welded into the receiver there. Fit was great, and in this case finish doesn't matter, but how can I get a finer finish? I tried HSS and carbide and both seem to give me similar results. On aluminum its more obviously got an almost extremely fine thread look to it. It's not bad, but I see some guys turn brass and bronze and aluminum and get like... gloss finish parts.
Its a 7x12 Grizzly mini lathe with the stock original gearing in it - no changes. Am I right in thinking that if I slow the screw travel down I will get a better finish?
