old wrench
Poster Extraordinaire
I was looking through the StewMac tools (once again!!!), and noticed the knob and insert puller that they sell -
www.stewmac.com
The price is quite stunning - $85 bucks !!!
But, all you need to build one is a some odds and ends, a few pieces of hardware, and a little spare time.
The heart of the tool is simply a small hard plastic jar - clear plastic is preferred so you can see what you are doing.
Cut the top off of the jar and sand it flat, then drill a 5/16" diameter hole in the jar's bottom.
Use a good-sized fender washer on the top of the puller - it spreads out the force exerted on the puller's top and reinforces it.
I used a scrap of 1-1/4" square tubing for the knob puller - if you don't have any square tubing laying around, you could get creative and weld or braze two pieces of angle iron together.
I made the U-shaped cutout in the puller a little over 1/2" wide so it will easily slip past the pots fastening nut which typically (on the large CTS-type pots) take a 1/2" wrench.
For pulling the threaded inserts used for Gibson-type tail pieces you'd use a 5/16" - 24 bolt or the appropriate metric size if you are working on an import guitar.
I added some cushioning to the body of the puller so it won't scratch up a guitar's finish - some rubber tubing with a length-wise slit slips on the edge of the jar and I used some weather-strip adhesive to hold it in place.
That's about it - a simple universal puller for guitar work - and we didn't spend $85 bucks for it either
