[@bobc8694]

When it comes to the balance on the rear axle. If you are going to be hitting that kinda top speed it would be money well spent to have the complete spinning assembly balanced. With everything all together brake disc , sprocket,axles , basically everything that's spinning. I'd even mark the lug nuts and have them on and then always put them on the same stud that they had been on when it was balanced to me I'd say it's just a good thing to do it can even play into the safety of things and bearings and such will last longer definitely a ton of work you have done looks pretty good ! Anyways have a great day

[@rexschimmer7394]

Matt, Great rear axle design! Looks like you could put 1000 hps through it. Mounting the brake calipers on the bottom of the rotor is not a good idea as you will have a very difficult time bleeding the air out of the system. You need to have the bleed screws vertical so that the air in the system gathers at that spot. We have the caliper (you only really need one with a solid axle) mounted on the top of the rotor and it is a real pain to bleed. I like the split sprocket also, makes it easy to change. One more thing, when you are "lathing" a long part you should really put a center in the part and use a bearing style center on your tail stock to hold up the end of the shaft you are "lathing". Even with a fair amount of shaft in the chuck if you take any amount of cut at the unsupported end you will have deflection no matter how tight you make the chuck. Keep it coming! Rex

[@DukeOfTwist]

Good point Rex, but I think you'll find it was the spool he was lathing was hollow with splines.

[@rexschimmer7394]

Make an aluminum plug that is a 2-.003 press into the splines, drive it in with a BFH, indicate the end of the shaft to be concentric, cut a center in the plug, machine "OPs" sorry "lathe" the shaft with live center in tail stock.

[@brucecarr6258]

FYI, we designed those axle bearings long, long ago, and for drag racing, which is a little different use, so a few thoughts if I may. I see you're running two on each axle. The bearings are double-sealed single row ball bearings, and are based on old GM and Ford live axle shaft bearings that are pressed on, one at the end of each axle shaft. Then three's a ring to keep it in place. This was because in drag racing, you have to run C-clip eliminators for obvious reasons. I don't know how well a pair of those will run in parallel unless the ball track grinding has improved a lot. Also, related to that, they were originally designed to run a bit on the loose side, first because the inner race expands a bit when it's pressed on, but also to compensate for often destructive tire shake from drag slicks, an issue you don't have. The lube might be OK, or might need to be looked into, not sure what's in there these days but it used to be a rather thick lithium-based grease so at 300mph it wouldn't all fling out to the outer ball track and/or overheat. You might want the efficiency of less viscosity. You showed the outer O-rings still there, but you don't need that O-ring outer ... that's there to stop differential fluid from leaking out, onto the brakes or tires, both of which are a very bad thing. Finally, if you're not running hybrid ceramic, you might consider that (although I've never done it myself), and look into the issue of seal drag ... we never considered lube viscosity or seal drag as issues with multi-thousand HP applications, but yours begs for every little bit of help. Cheers!

[@DukeOfTwist]

Drag racers are the best 'break it - remake it' engineers. All my life, I've always been drawn back to the sport, today I ran a TNT event at an Aussie Strip.

[@SuperfastMatt]

Great info. I pulled off the outer o rings. I also removed the seals between the two bearings, but I left the outer ones on to keep the salt and dust out. I chucked up one of the bearings in the lathe and spun it at it’s expected max rpm for three minutes and didn’t see hardly any increase in temperature, so I don’t expect any issues with heat or seal drag.

[@brucecarr6258]

@@SuperfastMatt Great engineering brain, already out in front of it. Glad you tested to your own max RPM, which is going to be significantly higher than the max RPM it would see with fully grown drag slicks. Took me a while to figure out that whole secret-PSI delta RPM thing, since those crazies use tire growth as an important part of a wildly nonlinear variable final ratio. Nobody would share telemetry for tire diameter thru the lights.

One other idea you could use for the rear axles would be stub shafts like what's on old C3 Vettes and maybe other cars. Basically just like what you had made, a flange on a short splined shaft. Downside is you're stuck with whatever ones you could buy off the shelf.

[@martylawson1638]

Actually you CAN twist and flex a drive chain. (just not as much as bicycle chain) Afik, lots of sprint cars do it. The key is to always guide the chain into the sprockets lined up and square. Aka, tight side has to stay in-line, but you can use sliders to nudge the slack side inline. This is what the rear-sprocket guide/slider is for on a dirt-bike.
