I need to make a tapered gib for the vertical slide of the table of my 8" shaper. The gib will be 8" long and will run against a cast iron slide. I can get bronze alloy 932 (SAE 660), aluminum bronze alloy 954 (10% AL), or teflon-filled delrin. Which would be the best material for the gib, or should I use some other material?

"Mild steel" ought to be fine. If you use cold-rolled, anneal it first or it will warp amazingly when you mill the bevels on the edges (guess how I know...). For a tapered gib though, a strip of cast iron might be easier to deal with.

There was a discussion about gib material a few months ago; check back in the archives.

I recently made a gib strip, and was advised to make it from EN 19 (SAE 4130 equivalent), as it would be more stable.

Its working fine.....

Rember that lubricated steel on steel has one of the lowest friction, so steel is the way to go (pun intended).
