There must be a virus going about
A friend's 17 year old son has an off road motorcycle with a broken rocker cover bolt . The shank is only 5mm and of course it is a few mm below the surface , it is surrounded by alloy castings and is stuck in the alloy head .
Heat is out of the question for fear of ruining the alloy , 5mm seems a little too small for a screw extractor and then there is the problem of just how to get the hole drilled into the exact centre .
A left handed drill comes to mind but I have never seen let alone used one , any tips for using one ? Any other suggestions gratefully received .
This is a good' hard working and deserving boy and I would like to help him out if I can .
