Looking for a Tuning Fork

I want to get my hands on a couple tuning forks for bolt removal/replacement. I don't have the tools on hand to make them unfortunately. If anyone has some premade, or could them for me, that would be much appreciated. I want two of them.

You might contact Greg Barnes of ASCA. There were some Lost Arrow piton tuning forks available through ASCA several years ago. Perhaps they are still available.

I prefer a big tuning fork made from a 1" cold chisel or from a tile chisel. Cut a 5/16" slot and grind the tip to a more acute angle. Drill a hole in the handle for a lanyard, or easier, cut a groove around the circumference for 1/8" cord. These are capable of removing a 5/16" buttonhead. 

To protect the rock from gouges, consider using a piece of sheet metal. A 4" round disk with a single groove from outside edge to center works nicely. Slide the disk under the hanger and insert the tuning fork between hanger and disk.

It takes but a few minutes to cut a slot with an angle grinder and thin cut off wheel.

Take some pins or SDS chisel to any local machine shop. They can do it for you relatively cheap.

Guideline #1: Don't be a jerk.
