Hold Onto Your Head
Handy tool for working on your head, just weld a piece of 25mm RHS to an old spark plug, screw into the head and clamp in the vice. The first one I made use a bit of 25mm water pipe, and it worked okay until I lost it or lent it to a mate, but RHS grips in the vice better. My son made this one for me, did a good job of it too, funny how you think your ankle biters are just kids when they are actually 30 yr old skilled people. See photo;
