How much UHMW?

[alaskajosh]

I found delrin spring liners, but they only got to 2 1/4, the rovers are 2 1/2.

I'd say those would be worth a shot! It's only an 1/8" shy on either side. How's the cost?

The problem is they have a lip on the end to wrap around the spring to keep it in place, so you need that extra 1/8" to get the wrap, otherwise its too thick. The cost was around $16/20 ft @ speedway motors (much more attractive than $55/54 ft at mcmaster for the thin uhmw tape). My understanding is the delrin strips are slick like uhmw, but nearly bullet proof against abrasion.

Terri-no worries! The part# for mcmaster on your site is for the very thin adhesive tape. If I can find some delrin strips that work, I'll get you the info in case you want to post it on your site.

Anyone have a place, online or not, that deals with springs/spring liners specifically? I cant find a spring shop here in Greenville, SC...if so, post their number/site here or PM me and ill do the leg work/testing.

Whats going on, mike?

I called them and asked...they can send the disks but said drilling the spring is nearly impossible without the right tools.

This is a rebuild I've been putting off and would like to find out how it works for you.
Did they give you a price on the delrin anti-friction pads? I'd also like to go the POR15 with Delrin pad route.
I just need to buy a nice drill bit that can eat through the leaf spring steel.

I looked up the delrin liner you were talking about on speedway motors and think it looks like a really good option!! If Terri-ann is reporting that her plastic doesn't need adhesive (or a lip) to keep it more or less located why don't you get this stuff and just trim that lip off? With a razor knife or run carefully through a table saw or something? Try it and let us know how it works.. I wish I'd have tried this stuff!

josh, you're so willing to spend my money; much like my girlfriend

Seriously though, it may be worth a shot, but I want to try and find 2.5" with a lip first

[albersj51]

Did some searching today and called a few spring shops as well as speedway, but no dice on the liner with the lip. I'm going to measure my springs tonight and may order the flat liner from speedway. A review will be a while off since the old girl is in a million pieces.

Good stuff! Thanks yorker. My concern with the tips is the need to drill into the spring, which as I understand it, is a huge pain!

[bkreutz]

A good cobalt bit will work. (note I said good, this excludes the Harbor Freight cobalt coated bits)

[yorker]

Yeah they can be fun to drill. I don't think you really have to drill all the leaves though. Check out a few modern 1/2 ton trucks in your local parking lot to get some ideas.

[albersj51]

I called the guy at the link you sent and he said you only need the tabs/liner on the longest 3 or 4 springs, since that's where most of the movement and friction is.
