Does anyone have a source or a stash of 3/32” wheel retainers? I use them to keep prop blades on a 3/32+ Z-bar. Right now I’m cannibalizing one aircraft to fly another. Is there another solution to this problem rather than wheel retainers? If so I would like to hear it. Do you have any wheel retainers you would be will to part with?
I use the nylon keepers used on pushrod connectors. See: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXAHE6&P=SM
You can sometimes find just the nylon keepers without having to buy the whole connector.
Drill to 3/32 (or whatever diam.) and press on. Any scrap of nylon will work.
The other keeper is the spring like “doohickey” sold by Carl Goldberg.
I’ve used both on F1b’s (when we built our own!) and they are much lighter than brass wheel collars.– Norm
Thanks Norm. I will try the nylon “keepers.” What a good idea. The spring doohickies is what I’m looking for. I’ll give Goldberg a try.

Harry Higley & Sons ( http://www.harryhigley.com/ ) has 3/32 wheel retainers. They are steel, though, so a bit heavy. 😥
Thanks guys.
The nylon keepers/push rod connectors are not available through our local hobby shop. They (nylon buttons) have been replaced with a spring steel washer that must be destroyed to be removed. Don’t know what those things are called. As you suggested Norm, I’m going to try and find some material I can drill out to 3/32nds and use that. I would much prefer to make my own as it gives me more control over the out come.And CapnRog, thanks for the link. I didn’t buy the wheel collars as I had already been to the hobby shop and picked up a pair there. Now, if I can just keep track of that tiny Allen wrench.
Look at the R/C fittings. They have nylon wheel keepers for the electric planes (look like little caps). You can even use nylon control horns, drill a 3/32″ hole and trim until round. When I was a kid, I used nylon prop tips.

Will do. Thanks again.
Brodak Mfg., supplier of control line stuff, sells aluminum 3/32 wheel collars which are nicely rounded on one end and secured with allen set screws. I just completed a Z wire front end for a Mulvihill model and really like these. I believe their website is http://www.brodak.com.
Here is an update of my search for 3/32” wheel retainers. I bought steel collars and I’ve drilled out some plastic disks* and played around with them. What I found out is there is a considerable difference in weight, relatively speaking. In the process I had an idea for a different material…electrical shrink tubing. It looks good on the bench although it hasn’t been field-tested. Weight wise it is the winner.
Steel collars 1.0 gram
Spring coils .18 grams
Plastic disk .18 grams
Shrink tubing .02 gramsThe disks are plastic protectors from the Bayer Co. lancets used by diabetics.
