Hammond B3 Keycomb Rehab - Part 2

This part just shows the process by which I refurbished the key combs on my Hammond B3 organ. To perform this operation you will need a #34 drill bit. In a pinch you can use a 7/64" but the hole will be about .002" too small to accept the screws.

For the white keys I use #4-40 x 3/8" phillips pan head machine screws with a washer that measures .312" outside diameter.

For the black keys I use #4-40 x 3/8" flat head socket cap screws. You *don't* use a washer on the black keys or it will disrupt the playability of the key.

I would rather buy the combs from Tonewheel general hospital. for $350.00 delivered. this is way to much bullshit to go through to get a few more years out of your combs. plus i think you will eventually have problems with screws coming loose. way too much crap to go through.

Buying new combs is certainly one option, but this is directed more as a DIY or for someone who doesn't have $350 to commit to new parts. The total investment for the fasteners and a drill bit is about $20. You can eliminate the issue of screws coming loose by using a low-profile nylon lock nut instead of a plain hex nut. It takes about 2 hours to do all the combs which is negligible if you're this far into a restoration. Plus, you could always buy new combs and keep the old set as a backup.
