Hi
I'm starting to make some mechanical drawing for
some 11 hole punch blocks that could be used for
any combination of auto or manual punching.
[...]
This is what I have so far:
Spindle hole 1.125 dia
index hole 0.10 dia
index relative to center of disk 1.00 radius
Spindle relief hole 1.5 dia
Thickness of complete disk ( not counting folds at edges ) about .070
I'm hoping that there may be enough interest in these to make 10
or 20 units. This would make the machining cost reasonable.
I need one for 16-hole disks too :-)
