I just received my first set of diamond tuning pins. They are indeed more consistent in size and beautifully machined.
I was going to use them on a 1902 Chickering, 4 part block, which we fabricated to match the original sandwiching quartersawn maple between layers of Bolduc block material. Attached photo was not yet fitted to plate .
My question is that the Diamond pin threads are much more pronounced - harsher. I'm concerned about driving them into this odd block. I've tried a few samples and had to modify the bit size for 2/0 X 2 3/8 pins for proper torque.
Do you drive your Diamond pins or turn them into the block?
Do you drill out the block differently for the Diamond Pins?
Any advice, anecdotes, wisdom is welcome
