Hi Joe, what kind of pinblock material?

>(ie the thickness of the tuning pin web on the plate). 5. Bandsaw the

Ok, got it.

Very familiar concern, very familiar result. There is likely an interesting 
collection of aging small partially manufactured parts here and there under 
large never moved things in my shop. The super sucker shop vac works pretty 
well as a catcher for small parts coming off of the blade - either band or 
table saw.

Yea, making 250 of anything you ought to be able to buy for a tenth what it 
costs you to make them is always a pain. Why would drilling the hole first 
make a difference in how the top layer holds together? I would think it 
would depend more on the material used and the drill than the sequence.
