[CAUT] existing pinblock prep

[Willem Blees]

Medium speed, and just drop it down in and bring it back up in about 2 seconds. A lot depends on how much "crud" is in there. If the pins came out with a lot of rust on them,?it might take several passes. But if the pins came out clean, just once should be sufficient.

Hi list,

New topic! ?When restringing and retaining the existing pinblock - for instance, the pins are not loose, but you are improving bridges, capo, agraffes, etc, - do you use anything on the pinblock holes, such as gun cleaning brush (what size?), reamers (also what size?) and what results have you had? has anyone done any "scientific" research with this? As in, I've never treated some holes one way and others a different way to check results. Just wanting to know what you prefer.

Thanks,
