I thought I should give these old soldering irons a birthday (especially as I just used the one which doesn’t have the lead cut off to repair a tap spout which would have cost me £70 to replace!). They were inherited from my dad. I was thinking new rubber cables, but the strain relief grommets are well perished. I was thinking it would be simple enough to find replacement grommets but I've just spent 30 minutes or so and I can't find anything suitable. I guess the originals are intended for a 1/2 inch hole but 12mm would be fine. I've tried Ebay, Farnell, RS and general searching on the web. Thegrommetcompany have the perfect thing but only in packs of 50 - what am I going to do with the other 48?? Any ideas where to look or how to improvise a substitute? I guess I could turn up some kind of adapter from derlin to use a slightly smaller grommet but it needs to be big enough to take the 3 core rubber insulated cable.
