Awsome, Just Awsome. Any chance of you selling these?

And if not how would you perfectly center the hole in the output shaft?

I made a simple jig from a piece of 1/2'' X 1'' X 2'' steel. The jig has to be made very precisely, if you can make it with good precision then it will help you have perfectly centered holes in your shafts every time. I just put the output shaft in it, flush with the surface, tighten the set screw so the shaft doesn't move, I put the jig in a drill press vise much like this one and drill in the hole of the jig which guides the drill bit.

I FOUND IT!!!!
Here's where I got the idea, it was ''its-me'' that came up with the idea of the posts. I was sure he used 4 but apparently he used two. So finally, thank you its-me for the brilliant idea.

Here's the post

So here's how I installed the Traxxas output gear on the Hyper 7 CD that scjrss made. Here's the cap made from the Hyper 7 spur gear with the 4 holes that are threaded with M3 threads.



The red you see in the holes is just something I am trying to stop lube seapage between the threads and the screws. It's very sticky and tough tape used to tape the seams when you put vapor barrier on your house's walls.



Here's the CD assembled ready for the output gear.



Other than the center hole that was trimmed to let the 8X12X3.5 bearing go deeper in the gear, it didn't need any more modifications. The thick spokes of the output gear are lined up between the threaded holes of the cap.



Four M3X16 mm flathead screws that were trimmed down to 14.5 mm in length to secure the output gear to the CD.



And here is the final product ready to use.

Finally here's how I put the Traxxas output gear on the CowboyRay CD. Here's three shots of the machined diff cap. This is a well used cap so that's why it looks a little grungy.



A shot of the stock Traxxas output gear on the left and the modified one on the right. Some grinding was needed in the spokes for the screws to meet the holes in the cap and some grinding of the spokes from underneath the gear so it would fit on the cap's elevated portion.



Here's the CD assembled.



And here is the output gear on the cap lining up with the cap's holes for the screws.



The finish CowboyRay CD with the Traxxas output gear using 4 M3X8 mm flathead screws to secure it to the diff cap.

Are all of these CDs for the e-revo? I would really like another CD option for my nitro conversion. The LST diff option definitely looks like it would be easy to make. Great job btw.. the diff looks great.

Yes, they are all for the E-Revo.

I have a CD I made for my nitro Revo using scjrss's method but with Thuder Tiger S3 buggy parts like the CowboyRay CD. I will look into making a new CD for my nitro Revo with the Losi LST XXL parts and the ''it's-me'' post method. I will see if I can use the output gear from the nitro Revo Traxxas CD or maybe adapt a different Traxxas gear that has the same tooth count. Or maybe just use the same gear CowboyRay used.
