I need to attach some PG9 cable glands to enclosures where the walls are thick enough that the lock nut is barely hanging on. One possible alternative is to try and cut a thread which wound be M15-ish, 15.2mm, 0.41mm pitch. Problem is that's an odd size to get and I'm not sure cutting a plastic case will work. Any thoughts on this? Glue is out, the two components are nylon and PVC, even for the few adhesives that will handle that they won't deal with the mechanical stress of clamping the cable.
I was in Bunnings to see whether they had anything suitable but wasn't terribly hopeful because M15 threads are pretty rare, when a random guy who was nearby and heard me talking to one of their tool people said "use a bolt". Then, when the Bunnings person had gone back to shelf stocking he added "there's a bolt shop just up the road at X".
Of course, it's the perfect solution, find a bolt that fits the thread and use that as a thread cutter! The bolt shop didn't have anything M15 but an M16 nut fitted the thread so I've now got two M16 bolts ready to be converted into thread cutters by milling in slots to take up the swarf.
Thankyou random guy who happened to be in exactly the right place at the right time! It would have taken me forever to get sorted.
