I’d say that there is at least a benefit to using it on a cnc because you can climb mill with them without much trouble. It’s not something I’d want to do with my carbide when I use them on the manual mill.

@@artisanmakes Sure, it is useful for CNC, it is not *just for CNC,* and certainly not designed for CNC. In my incredibly limited experience, your success with climb cutting is down to experience, rigidity, and backlash.

A 14.5 PA angle gear very close in profile to a ACME thread profile, biggest difference is the pitch

It probably would have, but I know a year from now Ill bump it too hard and it'll break off

It’s a tapping/cutting oil I picked up.

You could machine the taper, but not all of the counterbores needed for adjusting and retaining the gib strip

Never head of the soap method. Your probably right on the first point though, the only part I’ve ever successfully brazed was a moderately thick aluminium part. Cheers

Give it 100 years maybe. Just because something isn’t hardened does not mean that you’re going to see it wear down like crazy. It’s still steel. As long as you keep mild steel oiled and prevent it from galling it’ll be fine. Heck even sherline uses aluminium in their cross slides (not that it is a good thing because it isn’t) but 5 years old use and there is practically no wear in the cross slide.
