What steel to use

[James WaltonParticipant @jameswalton44680]

Hi there, I am currently restoring a 1930 Colchester Master and have stripped it down to the last nut and bolt. The engineering carnage is not as bad as I thought however I will have to make a number of gear wheels. 5 Change wheels, forward and reverse tumbler gears and main spindle drive wheels. Most importantly longitudinal and cross feed drive wheels. What steel should I use as some of the wheels transferring power have to have significant strength.

James, EN24 for gears would be good.

Hi James,

It may be a challenge, but it looks essentially complete and should be a rewarding journey.

You won't need exceptionally strong steel, the original change gears were probably cast iron.

Hope your lead screw and feed shaft are still straight after having that sling round them
