cliff.b Posted October 17, 2022 Report Share Posted October 17, 2022 Fitted rubber buttons twice now and they just don't last. Does anyone have any experience of the "enhanced" ones, what are best to fit and where from? Link to comment Share on other sites More sharing options...
Colin Lindsay Posted October 17, 2022 Report Share Posted October 17, 2022 I was looking at these last night... not yet tried them, but was debating it! Definitely got to be better than some of the current sponge varieties on sale. https://www.ebay.co.uk/itm/255751011061?fits=Car+Make%3ATriumph|Model%3AHerald&hash=item3b8bf2baf5:g:CLsAAOSwLBdjNcup&amdata=enc%3AAQAHAAAA4J4h0KubwLsfZ%2BsCWSrueS%2BoiTs7LHw8y14ANCdBJEGDhptURcDjEjzsNScOXTNDhtWClWuZASGmhcNPCOkSoQSok%2FkXztg%2FqqKX2RmdQqcxwPz%2B%2Bqpj2CBNOSIpn3v3YbNQ7e1aa%2B6fmkKdwiIPii454UqoEOGIRmet0LjCqzP92N44HN%2FSFVdorhYHQx0vRgjFI0gQx4k%2F5hW4NNfe%2B7Zf1CsEGiKRGJoKEGNHTVsqvvABnqKODpO39Yr7HFsScgqPrUsmHnspc9VyzDwuRsnnkhFf7tgybumj2R0wBMeT|tkp%3ABk9SR4aa6tv8YA Link to comment Share on other sites More sharing options...

trigolf Posted October 18, 2022 Report Share Posted October 18, 2022 I see that Superflex also make spring leaf buttons. I like the quality of their other bushes. Link to comment Share on other sites More sharing options...
Badwolf Posted October 18, 2022 Report Share Posted October 18, 2022 Annoying that. I was looking for some a couple of years ago and couldn't find any, anywhere. Now everyone's got them...wonderful. Anyway, it's not coming out again! Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted October 18, 2022 Report Share Posted October 18, 2022 There was a lot of conversation on here re this subject in February under “Rear Leaf Spring Refurbishment” I didn't know Superflex did them …otherwise I might not have struggled to make some! If do you want to make your own, probably the best material for this is UHMWPE- “ultra high molecular weight polyethylene” Cheap. available in bar form It will last longer than Teflon and polyurethane, rubber etc.Very tough, “ slippy - self-lubricating” It is very frustrating to turn on a lathe - I made quite a pile of failures to get a few accetable ones. It seems to be a material that shrugs off pretty much anything ( except high temperatures) Link to comment Share on other sites More sharing options...
Colin Lindsay Posted October 18, 2022 Report Share Posted October 18, 2022 When they stopped using these in Northern Ireland we lost a great source of material for everything from bonnet cones to bushes. Used to pick them up off the roadside and turn them in a lathe. Excellent quality material, so sadly missed. 1 Link to comment Share on other sites More sharing options...

ed.h Posted October 19, 2022 Report Share Posted October 19, 2022 For DIY spring buttons, the important material properties are friction coefficient and compression strength. It looked like most of my originals failed in compression. After consulting some material spec charts, I chose an acetal plastic (Delrin). It is nearly as slippery as Teflon, but much stronger in compression. Some pics here: http://bullfire.net/GT6/GT6-8/GT6-8.html Ed 1 Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted October 19, 2022 Report Share Posted October 19, 2022 I have used acetal, polyoxymethylene, POM, for anther purpose. On the lathe, it proved to be a pleasant surprise, turning very nicely in contrast to my experiences with UHMWPE. Apparently acetal can deteriorate in UV light, so available in black for outside use ( though can’t think much daylight gets between the leaves of a spring under a car) There are so many polymers around -it looks like we will be seeing more of PEEK - poly ether ether ketone everywhere from orthopaedic implants and fracture plates to light weight car components.
