Click increasement factor is that buying more usually means lower price per item as well.
Especially with the basic small Chinese parts.
So I have 20 of them brass studs on their way, since the second 10 were half the time cheaper...
Also goes for bearings, diff balls and what not.

J-B Weld on it's way (and one for my brother's birthday)!
I suspect this stuff will come in handy lots of times. Not only for the crossmembers...
Looking at my other (few) cars, I think I'll fabricate a couple more of them.

Oh my, I'm even finishing this little project...
Hollow carbon outside, steel center and brass ends with 2mm thread (fixed with epoxy) :



Too bad the carbon of the one on the right cracked in the process but I can fabricate about a dozen if I like.
I'll finish these ones first though...

High end production equipment :



First step of repairing the crack - superglue and some sanding :



Filling the top end with epoxy using a safety pin :



Then a 2mm (laptop) stud gets inserted...
Keeping an eye on this at first so they stay aligned and then it'll take a day to harden.



If these prototypes work well I'm gonna make some more.

The general idea :



The end.

I don't believe that - it's going to go through several rebuilds, some involving bloo anodised alloy & titanium fasteners

No hop ups (yet) but some further development making the system height adjustable for a Hummer body.
I took the original part on which the Humvee shell clamps in front - and chopped that up (even more than on the picture) :



Then I needed some kind of hollow 5mm tube that I could fit over the body posts... and found I had some carbon in that size!
This will be made into vertical posts that can be attached to the Hummer bit above with epoxy.
Cutting and drilling the stuff is a very fiddly job. It tends to crack easily.
So I'm constantly impregnating (no, not making babies) the carbon with CA glue and sanding that in the process.



Much ado (this thread) about what only seem to be some tiny bits (the work that went into them though) :



The bottom two crossmembers are actually a bit too short...
Got the length exactly right (61mm) with the third one I made.
Anyway, the height adjustable front :



And a double crosslink on the rear (couldn't get a focused image there , tried a few times):



Added some Grasshopper wheel nuts to compensate for the shortness of the bottom one.
I think I'll make a few more crossmembers in the exact size...

Like this, there's 12mm adjustability - limited by the front (8mm down and 4mm up from where it is now).
But different basic body posts would make a much larger range available.

I've got something like that on my BF:


thread rod from hobbystore with 2x2 nuts

Cool! That looks stronger, what I fiddled together a bit slicker.
