So I was using .25 material and an .125 end mil in plywood.
I did not put anything in the allowance box.
So my question is this.
IS the allowance bases on anything other than just a guess
Of course it is. And no it is not. End mills often cut something other than their stated size. They could be undersize or oversize and they may not run true in a collet. Wood is different in that it has fibers and those fibers can be springy, push down, pop back up.
If that is correct what might be a good starting point for an allowance.
Hard to say actually. But keep in mind that when you adjust size you should always recut both pieces. That said remember that any size adjustment you make is actually quadrupled. Each side of the slot on both pieces. So it is advisable to make very small changes, like a thou at a time unless you can see that it is REALLY off.
