Just had an aggravating time forcing the 4-40 blind nuts into the nylon sliders. Brodak kit parts. What experiences or options have you used?
-
Drilled out the center hole a bit than set T-nuts with some epoxy and a tap or two with a ball peen hammer. This sets the barbs into the nylon. Haven't had one come loose yet. 8)

I do the same with these exceptions.......rough the nylon first where the epoxy will be and I use a vise to push them in instead of the hammer. I have bad fingers as it is and I always end up whacking one! LOL H^^
-
Thats about what I did, but used CA and kicker then chased the glue out with a tap.
-
Brodak used to supply the assembly with the nylon sliders installed. Probably a cost savings. John should be made aware of the difficuties, but they will most likely cost more.

I by-pass the issue by making my sliders out of aluminum with nylon inserts for the lines (nylon eyelets really). That way I just tap the aluminum for the screw. Not sure I'd trust a blind nut in nylon even with epoxy or CA, but it must work as others have used it successfully.
-
I make my sliders from plywood and bush the line holes with short pieces of Goldenrod RC flexible pushrods. I put the sliders in a second ply (the part glued into the wing) part and the Goldenrod acts as a guide to keep it all lined up.

Would anyone have any photo's of their home made sliders? I much prefer building my own stuff whenever possible. Makes the whole experience even better! H^^

I use phenolic with a blind nut epoxied in, and brass eyelets.
Its easier to build the slotted part versus cutting it from a solid piece of ply.
I use 1/8" square spruce or bass sticks.
The 1/8" sticks give the right slot spacing for the 4-40 bolt .

Control Line Central sells the "home-made" Tom Morris leadout guides. I got the link, thinking there was a picture there. No pic, but here is the link --

The ones from CLC are not as neat as the ones Alan Perret showed. The CLCs are essentially like the Brodaks, but made of ply and longer eyelets like Alan's pics.

I like to put an elastic stop nut on the back of cap screw. Not tight enough to stop the slider from moving. Just a precaution to eliminate losing the "T" nut, or the slider. Guess how I learned this? ~^

I make my sliders like Randy Ryan does. I drill the holes in the slider plywood before I saw the slider out.
