Default Don't buy links - build them!

Since I'm starting a new project I decided to see how hard (and expensive) it really is to build links for my AX10.

Cost:
1 pack of Traxxas Revo link ends (soooo much better than axial ends): $8.00
2 one foot lengths of 8/32 rod: $2.50
2 feet of stainless steel tube: $3.00

total cost $13.50 for homebuilt lowers versus $40 for axial parts at the LHS.

Also needed:
8/32 tap
tubing cutter
callipers (ideally)
demmel or saw for cutting rod

check out the stock axial 3mm thread compared to the 8/32 rod:


You can make them any length you want, Stainless won't snag on rocks the way Aluminum does, the Revo ends use metal balls and are way tougher, and if the 8/32 threads ever pull out you probably broke the rest of your rig anyway.

Tap the revo ends, measure and cut your rod to close to the length you need, adjust the length (you can unscrew the ends slightly to make the link longer or cut a bit more rod off to make them shorter), then measure the exposed rod and cut a length of tubing to sleeve it. Takes some time but it's not hard.

+1 on diy links. 1/4" brake line also works great over 8/32 all thread if you can't source stainless steel or want to buy everything locally. Delrin links are just as easy with JeepinDoug's drill bushings.

Yup that works.

This isn't really DIY but i'm sure a bunch of you old timers have those Traxxas steel links. They are the smooth silver 4mm, or longer black 4mm, can't remember part numbers. I like to chop the thread off the end, cut down the link to the proper length, and braze the thread back on. The links on my jk build are built that way.

Set of 8 Revo turn buckles and pushrods are $16 shipped on ebay and I get 4 strait links and 4 longer ones that I can bend to fit. Comes with all the rod ends and the length is good as well. JFYI.

10-32 threaded rod and 1/4 stainless tube work well for me.

I've swapped some of my links for those, and all of my rod ends on my other links to the Traxxas ones.

In my area delrin rod can be sourced alot cheaper than stainless tubing. Although steel links look a lil cooler hehe so I'm thinkin of trying it next time

Thanks, links saved It's super easy to chop those down and rebraze the threaded portion on the end.

I haven't seen one of those rigs in quite some time. Must be a super cool rig

I use Revo turnbuckles and pushrods as well but I had an extra set of Lunsford Titanium turnbuckles and rods so I used those. They are real light and extremely durable.

Thats the way I make links. Brake line, threaded rod, and rod ends.

I just tried out the threaded rod and brakline method last night. I busted out steering linkage and uppers and it worked out very well. It does add a little more weight but it is down low.

I need to make some bent links and I keep thinking this would be the easiest way as well... but you need male threaded rod ends and I can't seem to find any for RC. Where do you get yours? Mine will be for my Losi Mini so I don't want to get to big.

Why would you need male threaded rod ends? You could just make links using this method and then bend them or buy some aluminum tubing, bend it the tap and use long set screws to secure rod ends.. OR get some delrin rod (1/4", 5/16", 3/8"), drill and tap then heat and bend. No need for male rod ends at all.

Damnit! your right. I wasn't even thinking of using a long set screw... I'm new to crawling so I haven't really seen much, all I have to go off are my own thoughts, I'll be honest I'm mad at myself for overlooking that though its a simple enough solution.

I'm gonna go make some tomorrow, thanks for the help!

If you can't find long set screws another option is to cut sections of all-thread, that's how I made my delrin links. But I do recommend set screws as they are much easier to assemble.
