[pianotech] Renner hammer boring jig

[David Love]

To be completely honest, I think I never noticed that adjustment on mine.  I
do so few uprights and so rarely alter the rake angle that I never bothered
to check out that feature.  It’s even a better boring jig than I thought!

Yes, Marcel, it looks to me as if the rake angle is adjustable right on the
jig as pictured on the website
<http://www.lloydmeyer.com/productcart/pc/viewPrd.asp?idcategory=8&idproduct
=26#details> , but it's hard to tell for sure. The description suggests that
there have been recent improvements to the design, so maybe your's is not
adjustable, David. And BTW, thanks for pointing out that this angle could
always be introduced by an adjustment of the drill press itself. Sometimes
the obvious escapes my notice <G>!

David, I hope you will allow me to disagree. On my Renner hammer boring jig
the rake is adjustable.
