I just got one of those "You need to buy this tool..." e-mails and it made me wonder how many times someone just clicks and purchases rather than simply making up whatever they need from a bit of scrap.  The actual jig used here isn't nearly as important as just giving a passing thought to the actual need to give someone else your dollars for something so simple to make.

Here's my version of an almost no cost vise for holding bridge blanks for work as necessary.

 

Top left... scrap of wood made into multi-purpose jaw to hold bridge material while working on it.

Top right... An example of use to sand top to desired overall height. Countersunk carriage bolt for flat bottom surface.

Bottom left... Jig can be used without 1/4"  carriage bolt and wing nut in regular vise jaws.  Here the bridge blank is held for slotting.

Bottom right... Jig can be used for multiple purposes.  Here it is used to drill bridge feet for 1/8" by 1/8" neo micro-magnets.

I got that email too, and I like your version much better. So far I just use my fingers, but I hope someday to attain to higher things and try making one like what you show.

I have a jar of old square nails from when I did roofing and I cold forge them into specialty micro chisels for any "that tool doesn't exist" moments. The last one was some 1.7mm butt chisels for my wood tuner button prototypes. I always try to make my own version of a tool before I buy it.
Also love your little jig, looks very handy.

Rudy,
What’s with the magnets in the foot of the bridge?

Rudy,

You have a knack for making tools that are as nice as the things you make with the tools!

I agree with your philosophy. Never pay for something you can do or make yourself.

Hi Charlie,

The neos are added in each bridge foot with opposite magnetic polarities to use with a new hum canceling magnetic pickup I'm working on.  They weigh almost nothing and are very powerful for their size.  Even though we love our acoustic banjos there's always a need for those who wish to amplify.  There's no reason why Tele players should have all the fun!

Great fixture! Thank you very much for that idea. One thing you might do is use a Chicago screw in the fixture and that way you could use it flat on either side, just a thought.
