Solution for idler wheel noise

[porto]

SUPERRRRRR !
I did that and it's very very good for the vibrations to go down from the idler because I think these are the main vibration who transmit in lenco plate.
Everybody needs to do this but I don't have PTFE washer and I wrapped all the washers in PTFE band and the results are very very good.
Thank you alexkorf !

Delrin® washers work very effectively in this application.  Garrard and Dual changed over from fiber to Delrin® or other low-friction plastics in exactly this kind of application, in the early 1960s.   

Used to be they were easily obtainable when scrapping out old VCRs but that trove of parts is just about depleted these days.

PFTE sheets are quite cheap on ebay (less than 10 euro) and I think are a must for anyone with a Lenco. I replaced all Nylatron parts in mine with PFTE (bearing and motor thrustpads). However the idler washers are the only part where using PFTE made an immediately audible difference in sound.

One EU based seller of these sheets:

I got mine here, they go well with PTFE washers.

Yes more   I traded the rest for the ptfe washers with a friend who builds
rc car models. So unfortunately I have none left to give to the other guys - but maybe
the ebay-seller ships europe-/worldwide

But I could buy a whole lot for everybody and send them out step by step.

That would be excellent if you could do it Chris!
I would be in for 3 or 4

Mmmmh.
No, that was my spare one.
I bought a couple of them today.

It´s a bit funny, since it only costs about 90 cents but maybe we could do that?

Yes please. I trade you for a couple of Bedaroe Bitter.

what kind of noise do the fiber washers make?
I apply a liberal dose of grease on mine, and haven't heard any noise. So I'm curious.

That WAS the trick on old record changers and turntables of all kinds, way back when only the fiber washers were available.  It worked well but the grease tended to dry out and had to be cleaned off and replenished in a year or two.

OK,.. that makes sense. I'm still so prone to taking the thing apart, and tweaking, that nothing has the chance to get to that point.
What do you think of lube products like Tri-Flow, a teflon enriched "oil"-like lubricant?  I've used it to soak precision bearing for my fishing reels, with literal overnight baths in it; and they'd cast immensely better after an overnight soak in Tri-Flow.

I've been trying to track down some ptfe sheet stock around here, but, nothing in the immediate area.

[GP49]

In light lubrication, Tri-Flow™ works well.  I would not try it where the solids might cause a problem, such as sintered bronze bearings where anything particulate might clog the material. 

I seem to remember it as "Tri-Flon" but the name changed.  Perhaps DuPont, the owner of the Teflon® name had given permission for the use of "Flon" but withdrew it?  Sherwin-Williams, the manufacturer of Tri-Flow™, now appears to use generic PTFE (that's what it says in their advertising, not the brand name Teflon®).   Or maybe DuPont never gave permission at all?

Guy, Michael.
I would love to do that for you but if you look at Felix` (flencolix) link above, there´s no contest here.
Mine cost 1.10 a piece (I said 90 cents but made a mistake) and I will use that link, too.

Thank you for the hint, Mike. This brand of lubricants isn't widely advertised in Europe, but I can immediately see areas where it might be very useful. Will order a couple of bottles asap.

Glad it was of use!

I've tried everywhere around my local area to find ptfe washers, or even of delrin - I even went to the best hardware/machining supply store in the county.  The best I could do was a come back monday, and I'll drill out some rod stock for you, and make some with a cut-off tool and a lathe.
I found that #4 flat nylon washers (sae standard) for an electronics supply house fit the shaft, and still allow the spring clip to fit, barely.
I'm trying those out right now. They seem to work well enough, but are about 2x thicker than needed; if one washer could be split into two, they'd be ideal..
