My little Sherline mill handles are even smaller than the one on the rotary table! I usually turn it by the outside diameter knurl anyway.
If I want to go fast then I use the speed handle. One of the speed handles was broken when I bought it. For $75.00 I was ok with that!
It was easy to extract the broken end and now I can put in a small allen if I want to but usually just have the one handle installed.
The way I see the offset for the eccentric bolt head is at about .015". I have enough throw to lock down any part. I made one with .030" and I was concerned that it would not "lock" so I stayed with .015. Even if the clamp is scaled up along with the bolt I think .015" is plenty. The key is the backup strap clamp. If you can make the backup clamps flush with the opposite side from the bite clamp then it will hold firm. Anyhow that is my take on them. Not very critical at all. Button head screws work fine but I think Low Head Socket Head Cap Screws would be best and that is what I plan to use for any new ones I make.
Cheers, JR
