Hi Carl,

Of course I remember you.  Most notably for your hand ball that I've used
for years on one of my tuning hammers and your wonderful key leveling set
up.  I'm not interested in any sort of sanding machine at this time.  Just
wanted some info about Jon's particular set-up.  Thanks,

jeannie

Hello, Jeannie.  I met you at the Reno natl convention.  I hope you remember
my demo of my hammer sander. Picture attached.

 

I sold a few and now Mother Goose tools are selling them.

 

There are many ways to skin a cat and I really don't want to see any of
them.  I don't skin many cats these days.  Even if Joe in Oregon hates them.

 

My sander grinds those puppies down to the core ( if you want to in jig
time), It can favor either shoulder or the strike point and you can do it in
20 minutes in an upright action in a cradle.  Easier  for a grand.

 

I provided a video tape (now obsolete) and now I have no incentive to update
it.  

 

Selling to Piano techs is a hard sell.  I'm opting out.

Thanks, Jon.  Are photos possible?  

To those of you who saw Chris' demonstration and are ready to try
it.....What would be the advantage to using an oscillating sander?  Does it
work that much faster?

The shanks are off the rail during the reconditioning process to be
repinned, filed, tapered,

tail arc'd and weight graduated. The rail sandpaper is replaced from a roll
available from

Klingspor; www.woodworkingshop.com; 220 grit for flat rails and fine emery
cloth for

tubular action rails.

 

I usually file at the drill press with a 1' drum sander. I have two elevated
surfaces to place the hammer for filing, one angled for previously tapered
hammers and one for hammers with

parallel sides. They're about 2" high to accommodate the rake of the bore.

 

A reshaping takes about 45 minutes, even for really flat hammers. Sometimes

a second filing with a fine paper drum puts a nice finish on them. Hammers
which

are not too grooved can be reshaped with the fine drum.

 

I was just wondering if the oscillation of the spindle would cause ragged
edges.
