Shock Cap thread and 1/8" hinge pins

[LusBus]

Hello friends of the RC10

Does anybody know what thread the shock caps have? Diameter, pitch, angle?

And: I would like to use metric hingepins (3mm), but they would have to much play. Has anybody made experiences using a sort of bushing? Should be 3mm inside and 3,175mm outside diameter which leaves a very very thin wall (+/- 0.1mm). Has anybody found/made/used something like that? Should be possible, but would need a precise lathe (especially the chuck).

Thanks a lot

Probably easier to find tubing with the correct ID, then ream the parts to fit the tubing.

The easiest solution is probably to order the correct parts from Lunsford. They still make them.

The Lunsford set is also inexpensive compared to other options.

Are you sure you need new pins? If you only need a or 2 you can get them off e-bay for about $10 a pair.

I am not certain on the shock caps, but the new 10mm hardware from the element trucks does not thread on to the older shocks. Are you looking to make custom caps for your shocks? the shock cap threads and size stayed standard from the rc10 all the way to the rc10b4. So there a number of caps that would work.

On my team car build I really liked the composite caps.

Thanks for all the hints and ideas!

Concerning the hinge pins:
- Reaming the original parts would be an easy solution, but I don't want to work on original parts, they should stay original.
- Lunsford is a good idea, but very expensive. I will convert at least 10 cars...
- I have 5 Meters of 3mm round titanium Grade 5 bar stock here, so I will use this.

New solution/idea: I ordered titanium sheet metal 0.1mm, this ist not so expensive (1/- 10 dollars a 10cm x 1m roll) and I will cut little square pads and roll and insert them into the parts... I will post an update if this works well...

For the shock caps:
I will build a few cars (at least 6 with longer front arms using my twin-plate chassis, truck noseplate and longer front arms. So I need 6 pairs of longer shocks (they where called "rear short" at hte time)

I will use this chassis: https://www.rc10talk.com/viewtopic.php?f=35&t=47249
and these arms: https://www.rc10talk.com/viewtopic.php?f=35&t=47141

If you measure the lengths you need, the turnbuckle sets can be pieced together more cheaply from steel parts made by Schumacher. This site shows many of the options available:

The Quadra shock tower from Factory Works fits the truck bulkhead and uses the buggy length (0.71) shocks.

Alternatively, they also offer the RPM tower. It uses the truck length (1.02) shocks but has the correct geometry for a buggy. It also has more room for the body to pass through.

Thanks a lot.

To be very precise:

- Shock towers are not the problem, I will design and cut them on my own anyway. Of course I could design them for .71 Buggy shocks, but I like the look of the long shocks. So I have to make shocks, this is why I am looking for the thread (diameter, pitch, angle).

- Turnbuckles are not the problem, good idea the Schumachers, thanks a lot. But I will make them on my own from Aluminium.

- Hingepins: I want to use the rods I have, 5 Meters of 3mm Grade 5 round titanium bar stock. I will try the solution with the sheet metal, will post my experience with it here.

Did your hinge pin idea work?
