[Shop-talk] Helicoil for plastic?

[jonnic1947]

Any mileage in something like this? https://uk.rs-online.com/web/p/products/0278556/?grossPrice=Y&cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Fasteners_And_Fixings-_-Sheet_Metal_And_Panel_Fasteners%7CInserts-_-PRODUCT+GROUP&matchtype=&pla-494253649177&gclid=EAIaIQobChMIt7eW26DK3QIVzb_tCh3Shw8gEAQYASABEgLvH_D_BwE&gclsrc=aw.ds Found by googling "threaded inserts for plastic". Many alternatives available, this has the possible advantage of using expansion force to retain it in position, as long as the plastic is strong enough. This is UK supplied but I've no doubt somebody like McMaster Carr can offer an equivalent.

The house was sitting long enough that they're all "sticky"--don't want to operate. They pull "up and down" or "in and out" to control water flow, then rotate to control temperature, not the "ball" type that pivot up to control flow, then swivel. I've never seen the kind I have before. They're all sticky (don't want to turn on/off), but the worst is the bathroom shower I'm using. I've pulled out the control knob several times. It is fastened to the control valve with a stainless screw into what looks like the phenolic valve. I suspect that I'm destroying the screw threads in the valve each time this happens. My initial plan was to cut into the wall behind the valve and just replace the entire assembly. Advantage: I know how to do that. Disadvantage: yet another distraction. However, maybe I can use a threaded insert to hold this handle into the valve for now. Googling "plastic helicoil" doesn't help much and I don't think I know the right vocabulary. Anyone have a suggestion for keeping this handle stuck to its valve and functioning as a shower for six months or so until its associated bathroom gets gutted anyway? _______________________________________________ Shop-talk at autox.team.net Donate: http://www.team.net/donate.html Suggested annual donation $12.96 Archive: http://www.team.net/pipermail/shop-talk Unsubscribe/Manage: http://autox.team.net/mailman/options/shop-talk/nick@landform.co.uk
