Thinking about making a stubby MT2 taper for aligning my rotary table (as shown in Howard Hall's book) and after trawling through the mire of messages about this am wondering whether it is better to buy a centre and cut it down (but it will be hardened?)

Howard suggested something 40mm (1.5 inches odd) long would be enough, what do people think? I can set the compound over and have a go but am wondering what other people do? Seems like it could be a pain (time consuming operation) for little reward

Guess the easy way out is to stick a centre in the RT and chuck, and line the points up but this seems a bit heath robinson (not very scientific)

Also doesn't allow the creation of workholding adaptors

I can find MT2 arbor blanks (used one for my slitting saw holder) but if I have to cut it down once again it's hardened?

Regards

Chris

Ah – interesting, thanks

Don't have an angle grinder so would be cutting by hand – and ideally I would like to bore out the end to allow interchangeable inserts, I was twitching a bit at the thought of this, particularly if it's case hardened.

Do have some carbide tools though…
