how do i post a pic?

You posted one! So is that an aluminum diff cup for the LST?

Yes, just a little mock up to show the idea.That's a maximizer diff cup with a vertigo locker and the plate in between is from a hot racing diff cup for the LST which has the right shape inside for the outdrive/pin/bevel gear .Those 3 just just screw together and if i counter sink the screws into the diff locker that will form the flat slipper plate.

Then it's just over to Billy's to borrow his skills and his lathe,a couple of bearings to buy and suitable a nut,i'm using the strobe pads and spur adapter,make a 6mm shaft,the other slipper plate and voila slipper/diff.
(well maybe not quite that simple but near enough)

Don't forget that you need a die to put a thread on the 10mm part. I will have to do some more searching to find an alternate way to do it from what you are doing that would cost less.

Yeah,you could do it for much less! just i already have these parts and reckon they should work.I'll never use the locker anyway because when i tried it it did nothing but bend MIPs.

Billy tells me that adding threads to shafts is no problem,any threads per inch i want so if you can find someone with a lathe you should be able to make the whole part on that.

You could integrate the shape inside for the bevel gear(it's just a little raised section and a recess for an o-ring to sit in) into the part or you could just use the diff ring gear in between since it already has the shape in it (just remove the part the bearing sits on) or if you like i'll send you the plate from a hot racing diff for free.(it's the same as the ring gear just without the teeth so you could just use the ring gear if you buy a complete diff on e-bay.

That would be good if you could send me the plate. But you are are in the UK, right? I am over in California, so shipping might be a bit much.

I shouldn't think so it's pretty small,if i just send it international air.if it gets lost in transit i've got more so i could make a second attempt.Just PM me your address.if it costs more than a few quid i'll let you know first,if not i'll just pay it myself it's really no problem at all.

Yeah the plate itself is steel but the diff cups were some kind of really crappy alloy so the bevel shafts just moved into the metal killing the bevel gears so i've got a few kicking around.I think you should be fine with the stock cup, i never had any trouble with those only when i "upgraded" to the lame hot racing ones.Maximizers are solid though(and shiny).there 7075 which is roughly twice the hardness of 6061.The others clearly weren't 6061 though.The plastic ones outlasted them considerably.In fact they're still intact.

Just a thought though, are you sure your XTM diff is like that.All the bevel gears i've ever seen are the same as the LST.The savage diffs are the same any way.The LST diff wouldn't be a bad choice though,and because it's a f/r diff you'll have one less set screw to check since on one side (in our case,on both sides normally) the shaft and outdrive cup are the same part.

Gustav, you have a PM. BTW, thanks!

The XTM diff has output gears that are solidly connected to the internal gears. Because the XTM diff uses 6mm outputs, I will just be using the output cups that I currently use. It will be easier for the front (the diff output thing)!

So wait, this might actually happen? Travis, let me know if you come up with anything that works!

We will see how things go. I will be getting more and more busy as the start of school gets closer, but I should have free time for sure. The biggest problem that I forsee is the making of the backplate.

EDIT:
I just took a look at the Savage diff. It is also a good candidate, and there are ones on Ebay that are cheaper than the LST diff. So the Savage diff seems to be a better candidate.

Does anybody know how much the ofna diff with the 51t or something close to that plastic spur costs with mounts ?. My stock diff has a 46t spur. If its not to exspensive i might get one to try in my mugen buggy mounts, If it does'nt fit i might have to use the ofna mounts. It's just a thought. If it's pricy i'll stick with my hardened pinon idea.

The cheapest I have seen was on ebay hippie. Try there. Had one the other week for 15.

If anybody has one with mounts, i have trade bait. But i wont discuss it public. You know what to do.
