Pin depth.

[jolly roger]

 I tried some thing new today. Drilling a bridge cap to install new pins.
How to drill all the holes to the same depth so I don't have to file the
tops of the pins to make them even.
I used 3 layers of heat shrink sleeving on the drill bit, to both mark the
depth and act as a depth collar. 
It's availiable in a variety of bright colour's,  I chose yellow, does the
job very accurately.
You need to stand the pins on end together to sort, and toss out, the odd
short or long pins. 
Heat shrink sleeving is availiable from Radio Shack or good electronics
suppliers.

Hope this is useful
