[pianotech] Renner hammer boring jig

[Al Pebworth]

David,

The Renner Hammer Boring Jig has the "Rake Angle" built into the device.  See:

http://www.lloydmeyer.com/productcart/pc/viewPrd.asp?idcategory=8&idproduct=26

You can set the rake angle, as well as the boring angles.  I have spent many a happy hour using this tool. I made the purchase when I needed to bore hammers for a Charles M. Steiff Upright, followed by a Grand of the same make.  Now, unless I order pre-hung hammers, I bore my own.

It will bore vertical as well as grand hammers.  There is a rake on some
grand hammers as well.  The rake angle is achieved by changing the angle of
the drill press platform.  If you are using a small drill press with a fixed
platform you have to shim up one side of the boring jig.  The rake angle is
not adjustable on the jig itself.

Does anybody know if this jig will bore vertical hammers as well as 
grands? I'm particularly wondering if it is capable of boring the 
extreme rake angle found on the old S&S uprights. Thanks,
