Just to prove I finally made it out of the armchair:
This is one component of a mod to add a "boring and screwcutting" speed range to my sieg C6.
I have one more pulley to cut and once the new drive belt arrives the C6 should have two ranges of decent grunt - 240 -> 2400 and 40 ->400 for boring and screwcutting.
Another question. The pulley "V" is 11mm deep - how can I get a clean flat cut in the bottom to eliminate the chatter marks in the picture? I know it doesn't matter, but I know its there...
Thanks
Steve
