Thread: An idea for a contact grinder.

FYI, sterling silver wire in these gauges is very cheap. It's a TINY amount! And even for all those tiny pins, with some losses, I used less than half of what I bought. 12 inches of both sizes cost less than a dollar.

IF you are not yet using a peck type feed on your drill, try it. What that does is brings swarf to the surface and allows a cooler drilling. Ok, "peck drilling" is setting the down feed to retract every so often and the go back to depth and finishing the holes. A little bit more time but less damage to the work pieces. Some CNC mills have the sotware to do it installed by the maker. Often use in PC board fab and electronics work.
