I rounded out Allen head in rear axle pinch bolts in my old 222 back in the day. I took it into an engineering place to seek assistance. They had never seen anything like a Dh bike, and were fascinated. 10 guys including the boss stopped work, looked at the problem, had a round table, worked out the best way and got it done, just for the challenge and novelty, didn't charge a cent (I think they decided to tack weld an Allen key into it, and even gave me a new bolt)
It was Friday arvo, so I returned with a slab for them.
Ask nicely, be genuine, and people are more than willing to help out.
