[pianotech] Cleaning actions, and hammers

[Dean May]

I like sand. I use 150 garnet, get it from Abrasive Products, (317)
485-7701. It leaves the surface very nice, not glassy smooth, but about like
after sanding with 150 sandpaper. Last time I ordered several years ago I
got 100# for less than $50. I use it outside and don't bother with trying to
reclaim it, though you could recycle it indefinitely.

Original question
John Ross, I do like the idea of using the sand blaster with glass beads.
I've been thinking for a while about a compressor.  What else do you use the
setup for, in addition to cleaning actions

Hi David, 
In the archives, you will find that some people use a specially made box,
that collects the beads in the bottom, for reuse.
I never got around to making one.
The amount of beads I use, is not that great, so any saving I would make by
reusing them is negligible, for me anyway.
For major usage, a cabinet would be advisable.
I use a handheld sandblaster that also is the reservoir for the beads. By
trial and error I determine the pressure to use.
Be sure to protect your face.
To contain how far they spray, I just have a temporary frame, with heavy
duty plastic.
Initially I used sand at a low pressure, but it roughened the wood, so only
used it once on the wood parts.
Used it to clean the hammers for a while longer.
Now I solely, use the beads.
Probably only $2-$3 each use, not going to break the bank.
Finish off, by more pressure, and just air.
Could be done outside in the Summer, then a protection booth wouldn't be
needed.
i also use it to clean the wooden parts of keys.
