Gustav · **8mm axles -** 10.27.2005, 04:51 PM

Does anyone know what size of nut/threaded section is used on the UE 8mm axles.I'm going to make some 8mm axles for the LST.

If it's more than 5mm are there some 14mm hexes that fit,i'd be using 8x16mm bearings so i doubt they could be much bigger than 5mm anyway for the hex to fit the inner race.

Also any suggestions for material and/or hardening would be much appreciated.I'm guessing tempering will make them too brittle,maybe it's possible to differentially heat treat them to just harden the pin area.

I was going to try to get hold of some spring steel,bad idea?

Thanks.

Ah,Ok i should have looked more carefully,they use a 6mm thread and come with a hex.oops.

The LST 2 uses 8mm axles but they're hollow buggy style,i doubt they're much stronger than a solid 6mm axle,they use a wierd 15x21mm bearing that retains the CVD pin.I might give them a try first.

Hollow tubes many times are stronger than a solid one...

you mean for the weight? A hollow 8mm axle isn't as strong as a solid 8mm axle of the same material.not in this universe anyway?;)

I have heard the same. The hollow tube is stronger than the solid. I think it depends on how hollow it is as well. I have not done test to determine this for sure.

Gustav · 10.28.2005, 05:43 PM

No that's wrong,a hollow tube is alot stronger than a solid cylinder of the same weight that's all,boring out a cylider doesn't make it stronger.

The UE axles eliminate the drive pin weakspot which according to them make their axle 10x stronger than a solid axle with the weakspot.Hollow buggy axles use a drive pin (the ones i've seen anyway).I'd bet my house on the fact that those 8mm UE axles are many times stronger than a hollow buggy 8mm axle.

I agree with the ue axles are strong. That is why I bought them.
As long as it hold up to your needs gustav that is the important part right. :D

Yep,i am going to give those LST2 axles a try,they may well be up to the job.If they're not the plan is to make some 8mm axles for the LST copying the UE design and using their hexes.I can make them on my lathe and have a friend do the threads and hex area(he's much better at it than me)That would be the bomb:cool: .Those things are seriously stout,i'll be impressed if you damage yours coolhand.

coolhandcountry · 10.28.2005, 06:01 PM

Had no luck on damage so far. They still like the day I got them. I love this ue stuff. I don't like the price. The cvd is not bad though. I kept breaking some of the other stuff up. By the time I break it and buy some more it cost more than the ue.

I've actually had good luck with the MIP 6mm axles,busted plenty of wheels but never bent an axle yet,i'm just planning ahead.50+mph tumbles are a different ball game to the 35mph ish speeds i do now.The one advantage for the 6mm is i use 6x16mm bearings with them which is alot of bearing, so good for the kind of speeds i hope to go with the 1950 on 8s.

Gustav · 10.28.2005, 06:27 PM

Coolhand,(or anyone with these axles),i don't suppose you could do me a favor and next time you have your axles out, measure the length of the part that the bearings sit on,if it's a similar length i might be able to just use the UE axles in my knuckles and just make a coupling to use with my CVD bones.

It's the length from the hexed area to the flange that i'd need ie just the length within the knuckle that the bearings sit on.Also the internal diameter of the part that the cvd bone fits into would be useful too.

I have a pic of them be side a rd logic axle. If that would help you out any. I can take a meaurement on a rd logic. I have one sitting in the parts lot.
It is 19 mm to the threads from the sholder for the bearing.

Gustav · 10.28.2005, 06:54 PM

Coolhand,you're a diamond!

I think that may be too short though,i'd need it to be 19mm to the hex on the UE but it must be shorter than that because the measurement for the RD logics must include the hex area aswell?

These are 19mm just for the area the bearings sit on.Do the UE fit any maxx knuckle?they're not specific to the ue knuckes and longer?(wishful thinking)

i appreciate your help though.Not to worry,i just spent alot on 6x16mm bearings.

coolhandcountry · 10.28.2005, 09:34 PM

I think it will be to short as well. It should be about 12 mm to back of the hex. That is an estimate. Bearings plus washer. I do what I can gustav. Let me know if I can help you any. Yes the ue fits most knuckle made for the maxx. What about the 6 mm version of the ue. Would that be better for you. stronger than stock yet retain your new bearings.

Gustav · 10.28.2005, 09:52 PM

I think they're quite a bit too short,the LST uses a 10mm spacer between the bearings which is quite a bit more than the space between the bearings on the maxx,this is the important measurement i think since they both use 5mm wide bearings.

Thanks though,it's reasonably strong with the setup i've got now and i've still got some options if the Lehner proves too much for these CVDs.It's the last slight area of concern on the truck,the rest is extremely durable after all i've done and ready for some big power!
