Hi Kip,
I realise it's a bit of an open ended question about the motor size,the new machine will be 1.8 x 940 and i guess i'll mainly be v carving signs in timber. I havn't even decided what router i'm going to use yet.
The Vee wheels are going to be Bishop Wisecarvers, it seems as they are a bit dearer now though- £20 each.
My thoughts were that using Vee rollers and ballscrew there would be far less friction than my previous leadscrew and Delrin nuts. I'm also planning to slow it down by using 20 x20 ballscrew therefore reducing the problem of whip.
I've just got to reduce the size of my pics of the existing machine then i'll upload them.
cheers zim.
