Bill,

I have had some criticism for drilling out the left over solder in a through hole opening but I have done it for years (not too many times though). I am just an old Osteopathic family doctor but have used a finger drill and the very fine bits with success. ?I was warned about drilling out the through hole plating but just added a little solder on both sides of the board. ?The few times I had to do that it did work…. So go drill! ?I would like to see what a “half” bit looks like…. Have had one root canal done but wasn't interested in the tools that day. Ha!

Be the REASON someone smiles today.

?Thanks so much for all the advice, I am not the first one faced with this problem. ? A local ham with a big history of radio repair suggested drilling out the hole with a #60 drill bit. ?But as a retired oral surgeon, I still have a handpiece that is used for dental implants. ?It is very solid and has lots of torque. ?There is a dental burr called a half round. ?I dont remember what it is half of, but it is probably about 1/2 mm. ?I used it to drill out the holes and here is how it looked.

I salvaged 2 of the caps that I removed and replaced one with a duplicate I had in my junk box. ?I am hoping I did not screw up any of the layers of the board, but time will tell.

tnx agn all. de ve3mrx Bill 72
