Kinda forced into it by my own inexperience - I didn't realise how easy it was to break scales at the pivot pin if you are a little heavy handed trying to extract the old pin.
Another lesson learned.
Congrats looks great to me. I chickened out after filing the pins flat and cutting a divot on one of my ivories. I only have a hand drill and or a pin vice to use and didn't want to risk it...at least on ivory. Ebonite, sure Id try because I hate that stuff and its stench.
Great job! Looks very nice indeed, and the brass liner should help to prevent breaking. Acrylic by itself works so easily and finishes so nice, but it is not all that sturdy. A backing is a nice touch.
I would put the wedge pin a little closer to the end of the scales, though. Sometimes the very tips of the scales will spread away from the wedge when you pin the pivot, if the wedge pin is too near the fat end of the wedge.
