A few months ago I posted my (not a collection of) lamps and heater on here. The most tired of these is the Vapalux 300X which has an issue with the cage legs which are broken where they should connect to the brass blocks which in turn connect to the carrying handle. Before doing anything about that I needed to get the nuts that retain the handle off as both were seized on; the good advice was quenching in gearbox oil (I think the auto stuff was recommended but I only had manual but that worked fine). So, the little brass blocks are free but the thread on one is knackered (not the nut as both go on to the other block quite happily). You can see in the pic how it isn't screwed in fully. I have two options I think - one is a replacement block which I am hoping someone has one of knocking around in the spares drawer which they might like to come to an arrangement over! The other is the more constructive one of re-cutting the thread. But I don't have any dies and I don't know which one to use. I could buy one but I'm not convinced I'd need it again and so that is hardly the eco friendly solution over just sourcing another block. A third option would be to cut the bolt short as it does go in some of the way (far enough of the way functionally) but that seems wrong. So, anyone able to help? I'm in Leeds if it is of any use. Thanks in anticipation.
