Hi

I have some display equipment which I need to disassemble. Unfortunately it's built very awkwardly. They seem to have used some sort of specialist tool which a regular tool does not have a clearance to access.

I need to weld just 5mm tip of a secure torx bit to a flat metal piece like a philips screwdriver tip at a right angle in order to loosen this bolt. You can see in this image attached that I have tried to shave off a bit of the torx key, but the amount removed is far too much and comprimises the strength of the key - it bends before it would move the bolt at all.

I do not have a welder, was hoping for some ideas on how to adapt a tool for this.

Get a piece of flat mild steel bar of suitable length. Something like 20 X 3mm, but anything will do.
Cut the end off the torx bit at suitable length.
Drill a hole a bit smaller than the torx "splines" in the flat bar.
Press the piece of torx bit into the hole in the steel bar using the vice, and a suitable size nut behind.
If you have to get it welded just grind it flat and get somebody to put a spot of weld on it from the back. Easy job, local garage will do it.

What size torx ? whats wrong with a standard torx key ?
