I don't know anything about mechanical design, stress areas, etc... but I do know that looks hella kewl ...if you've ever had to screw on a shock end on an xray shaft ...you'd know what I mean a hex on the opposite end like that would be so kewl

that is the best, most simplest and best "updated design of a old design" idea i have ever seen!!

that would eliminate all the pliers on the shaft problems. honestly, that would not cost much more to make than it costs to make a screw. seriously. there is nothing difficult in it and all the kudos to gain.

I actually thought this was the single coolest and most innovative feature of the JRX-S. I built an Xray the day before I built the Losi, and after wringing my wrists trying to get those shock ends on, the Losi was like a breath of fresh air.

Mugen shocks uses 3mm nuts which I think is better.

We talked about stress points earlier.
Wouldn't putting a thread on top of the shaft for a button screw be even more stress than just a hex hole?
OR
Does the addition of the button head screw add the stability back to the weakened shock shaft?
Also how is the security of the screw? Being as how shocks take the most action on a run, would you need thread lock?
Anybody got pics of the new Losi Shock Shaft?

I don't know if Losi says to thread lock them but I would.

I have a solution for X-Ray owners : get decent shocks Never had an issue with that running tamiya shocks and i tell you right away, it's a nice idea, only thing is it's impossible to make for different reasons, one of which being the fact that if you make a hex print at the end of the shaft and you use e-clips to keep the piston in place, you either end up with shafts with a lot of material at the end after the piston or with a very weak shock shaft. Also, for those who don't know, there is no such thing as a precision screw.

I think this is a great idea.

However, as has been mentioned, the extra cost of machining may be prohibitive. If the hex is indeed machined in the end, it would have to be "Shaped". This means that a very small, probably square or triangular cutter is punched up and down as the tool and work-peice rotate in a manner to correctly form the hex. THis is how internal gears are made when they are not all the way through. (that type of operation is usually broached, unless a very close tolerance and great finish are required). I am a journey level machinist, with over 800 hours in gear machining....

the main dificulty lies in the mere size of the work peice and tooling required to do this.

I am thinking an external hex, just larger than the shaft OD would work. The shoulder of the hex could be used to hold the pistion on one side as well, so you would only need the one e-clip on the other side. Then you could use pliars or better yet, a nut driver to firmly hold the shaft. It would also help reduce any problems with stripping.

I used to use my dremel to grind a slot in the end of the shock shaft, lot like the hex in the drawing, (only slot, not a hex ). But the dremeling has to be very accurate and some shafts hardly give you any material to work with so the slot ends up very shallow.

Yeah, i thought of that too. But like you said, it would leave the shafts pretty weak up top and you risk damaging the pistons when you put then in or out.
I don't see machining costs being that much of an issue.
If they were offered as option parts, you could charge more to compensate.
Right now I pay $9.00 for 2 xray shafts.
I would be willing to pay anywhere from $13-18 a pair for the convenience of the hex screw.

You guys might check out our locking shock shaft pliers at www.teamtamale.com on the RC Car Tools page. These hold the shock shaft of just about any shock securely without fear of damaging the shaft.
