How would the EN24T compare to 4140 or 4340. Personally,I wouldnt waste time making one from mild steel.

EN24T and 4340 are both chromium nickel molybdenum, 4140 being closer to EN19.

Are you using HSS or carbide tips? Tipped tools have no problems, HSS is ok if you keep an eye on your speeds and feeds.

Richard / Adrian
To pose the question a little differently, Are the cutting tips on the tools separate, as in clamped into the holder (Not the tool post holder) Commonly a triangle shape, that can be turned over, and around to give six cutting edges?
Thanks Adrian for your conversion.

got the bar today.. such a nice piece of steel ! seems a shame it chuck it in a lathe... will keep you updated with how it turns out ! fingers crossed the HSS bits will cut it without it killing them off...
finally managed to get the cam plate fully out today... just a quick question.. the two caps that are on the cam plate (which go around the axle) do these bolt up solid to the axle or does the axle slide/pass through them ?
