Debunking old stereotypes

I use 4mm threaded stock with my links. I then just thread that into the Revo ends...no drilling into the revo ends. That being said, I would drill the link material at about 1/8" and then tap that hole to 4mm.
Here is a link to a site that will give you drill bit sizes per screw size.

I order 4mm threaded steel in 1m lengths from McMaster Carr.

Just started building mine last night. Used 1/4" stainless tubing, .025 or .020 something wall. Insert 8-32 steel rod inside the stainless tubing and cut the tubing to fit btwn the 2 revo rod ends.
The 8-32 threads into the revo ends pretty easy by hand.
This is probably the easiest route. I have seen others take thicker tubing, thread the tubing, then take a small piece of all-thread rod and insert into the revo ends AND tubing. About the same, but you have a few extra steps.
The 4mm stuff mentioned above is just all thread by itself inserted into the rod ends. And it's steel.

I do similar but with 1/4" Delrin tube that I hollow out to 5/32" I.D....then push the 4mm threaded rod thru it....and cap off with Revo ends.
Well...the threaded rod looks alright, but I'd rather have something that looked better, so I'm sure I could sleeve it with some tubing. But I think after buying all the materials to make my own it'd cost around $10, whereas I can just but the 4 Revo Pushrods for like $16, and they come with rod ends and balls. It seems like it's way more worth it to just buy the pushrods.
Thanks for all the ideas. I'll keep them in mind for the future.
EDIT: This is just for upper links, as I have custom Delrin lowers.

I am lucky enough to work 10 minutes from McMaster's warehouse....so no shipping charges. It makes it more cost effective.
5' stick of Delrin tube = $3.25
3' lengths of threaded rod = $1.25 x 2 sticks = $2.50
Total Cost = $5.75 PLUS Revo Ends.
This is enough material to do all the links on one truck....and still have some leftovers.
Just yesterday I picked up:
5 sticks black Delrin tube
5 sticks white Delrin tube
12 lengths of threaded rod
and a 12" x 12" x 1/8" white Delrin sheet
Total cost was only $60....and that will keep me and my pals in links for a little while. Even after work tonight a pal is stopping by for me to throw together a set of lowers for him. It is nice to make your own....and be able to custom size whatever you may need.

See you are lucky. But Even $5.75 plus 8 rod ends (~$4) = $10. Obviously you have enough material to make more links, and it is nice to be able to customize them. Making them for friends or selling them for $10 a set or something would also be cool, since you're making a bunch anyways.

I use a 9/64 drill bit and tap with a 8/32 tap and use 8/32 3/4" long set screws from Fastenal instead off all thread that way you don't have to worry about jacking up threads cutting the all thread.Plus they have an allen key in the end,so installation is much easier.

did you have any issues getting .25 tubing over the 8-32 all thread? I am looking at mcmaster's right now and think the tolerances may be a little tight and wanted to know if you had any issues with that

The major diameter on 8-32 UNC thread is .164", so a .25" OD with .180" ID tube should fit no problem.
This is what I ordered from Grainger: Tubing, Welded, Inside Dia .194 In, Outside Dia 1/4 In, Length 6 Feet, Wall Thickness .028 In, Outside Dia Tolerance +.005 In/-0.005 In
It's listed under :3ADD8
Even at that ID there was plenty of room inside for the 8-32 to slide thru.

I only use 4mm set screws and revo ends for the lowers. I've never had a problem with 3mm set screws and traxxas 3mm ends on the uppers with 1/4 delrin drilled using jeepndougs drill bushings. I also use larger delrin lowers without problems. Tube and all-thread just has never seemed like a good idea to me. I do use thickwall alum 1/4 tube tapped 4mm for lowers. Plenty strong and easy to bend at what ever angle ya want. If ya really want strong, there are stainless and titanium links available. "thumbsup"
