How fast is the forum with good advice today? It’s never let me down yet.
I am in the middle of using some nylon nuts and bolts to attach some better trucks onto an old Rivarossi passsenger car. What can I use to “freeze” the nylon nut in place on the nylon bolt…only ca?
Testors, Tenax 7, Proweld, pvc solvent don’t work on nylon.
It’s Sunday. Lots of guys viewing the forum. 2 hours before the hardware closes. Can I get an answer in time?
Of course, I think I might just have to use ca.
One of the properties of nylon is that it is impervious to glue. It might be possible to imbed the nuts in epoxy, but the chance of clogging the threads is very high. Since there are so many other methods to attach trucks, why are you trying to re-invent the wheel?
I would think Lock Tight Red formula might work. (or a soldering iron…[:-^])
Nope, no method as good as this. There are no replacement trucks available for this model. I have some very nice Walthers metal friction bearing trucks that are a close match, but have large holes. I have a stock of nylon 4-40 nuts and bolts from Microfasteners just for this purpose. A few nylon washers, a few nuts and presto! This job took only 5 minutes.
And now, with the helpful advice, I think I will…
just give the nut a touch with the soldering iron. Good idea. Thanks.
Why not just bushing the truck and use a appropriate size/ type machine screw (2-56) and a washer if nec.
Thanks for your responses, fellows.
Found the perfect way, though without any weird truck mounting techniques. The large holes were offset in the 3-axle truck anyway. So I drilled a perfectly-sized 4-40 hole on the other side of the centre axle…offset just as the over-large hole on the other side. The 4-40 nylon bolts are a perfect fit and a touch with the soldering iron on the bolt protrusion inside the floor of the cars was a perfect seal.
No need to find a bushing to fill the truck hole to 2-56 or any or fussy fitting. The basic nuts and bolts are perfect.
And the frame was perfect for gluing a kadee box on with a half-height shim. I would include a picture but all four are back together and on the track.
I’m glad you found a way to mount them. I guess you were really determined to use that nylon. I hope that you still have thread adjustment in case there’s a need for any truck/ bolster adjustments. I imagine that if those trucks ever need to be removed, you could always chisel off the melted/ peened threads inside the car.
In a case as this, I personally would have used steel or better brass screws for any future interior lighting. The PUs would be copies of the JB lighting kits. If you ever work in lighting, you can use axle wipers and run through the floor for instead of using the bolster.
