The ali looking strip seems to be clamped to a length of timber, perhaps hardwood. On the workshop floor, or is it the floor pan, seems to be a strip of J section. I have probably got this completely wrong, but might we be told?Correct. The aluminium strip is the door-top trim for a chummy. The candles are to give a coating of 'soot' that, when burnt off, indicates (approximately) that the right annealing temperature has been reached - and any more will probably cause it to melt. The wooden former is a copy of the line of door top-edge with the aluminium section bent into place using multiple small clamps. Worked almost perfectly the first time, with just a small correction needed at one end.
