Take care guys with that Toolmaster division table posted by Dave. It is full of errors and inaccuracies. To take a couple of examples the 43 division figures will give you 40.5 divisions (approx) and

To add to my last comment about tapping a dowel for removal, standard dowel pins are only case hardened so they can easily be drilled and tapped. Dick -- http://www.homemadetools.net/ forum/ OFF-

Peter, I have tapped dowels to allow them to be removed. Dick -- http://www.homemadetools.net/ forum/ OFF- SET-tailstock-center-65965#post105972 http://www.homemadetools.net/ forum/s...995#post112113

Many thanks everyone! My immediate (and very temporary) use is to register the fingerboard on a classical (nylon strung) guitar before removing and re-shaping it (and the neck). I’ll be adding some

Peter, Straight dowels will likely give you all the accuracy you need. Since wood changes size with humidity and the seasons, one usually needs to allow for this by locking two pieces together at

There are two ways to use dowels for location. The traditional way is to assemble your mechanism, or whatever, and when it is right drill and dowel the joints so it can be dismantled and rebuilt to

Hi Peter: McMaster-Carr has a excellent online catalog, and will ship overseas. I think they would get you good rates. Also they sell dowel pins with tapped holes so you can pull them from blind

Thanks Dick, I’m in the UK though… I can see a blind hole being a problem for a pin that is tapped all the way in - to fix a handwheel for instance. My purpose would be to repeatedly locate two

Good call I forgot to mention that. Phill

Brilliant, thanks Phil, just what I needed.

Yes no problem pre-drill a hole to depth then use the reamer to depth, you might have to do a test cut in some scrap to achieve a snug fit for the pin as you don't want the pin to bottom out. Have a
