Exactly why i don't take my press drill, because i've one
My press drill is so bad, when i put an 1/2" drill bit on it, i obtain an 5/8" hole.
This press drill whoble like any other can do
So i prefere to pay to have precise hole than losing my time with this f... press drill

I've recieve my spur gear adaptor yesterday from the machine shop, i'll try to post some pics today.

OK take a look where my project is for now!
I'am realy satisfy to the result.
Here you can see the spur gear adaptor with the stock revo tranny output shaft. You can see the spline on the shaft, and it's the allen screw on the adaptor who'll lock it into the adaptor. But the hole in the adaptor and the diameter of the spline part on the shaft is at "zero", so it's taper. I'll have to heat the adaptor to slip the shaft into it.
The only thing i'am not sure is if i'll lock the allen screw a groove part of the spline, or if i'll make a flat spot on the top of the spline and lock it on this flat spot;



Here is a shoot with the mechanical brake that i'am to install on it.

Looks very, very nice. good work!

Excellant work !!!

Very interesting David, I thought that you were going to use a center diff? I see why you used the revo output shaft, to keep the stock center driveshaft length!

Also like the use of a bulkhead to do the mech brakes. Lokks good, can't wait to see it finished!

BEEFY!! I like. Looks really good. You should be able to make a lexan gear cover for the center gears real easy.

My first idea was to use a center diff, but it's quasi imposible to install a rear mechanical brake, the motor take all the space. And i don't want to use the controller to brake.
So i decide to make an adaptor and having an all time 4wd.

I hate to bust balls here but someone has to say it, locking a revo tranny in second would have accomplished the same thing and been much simpler, that being said, its nice work and a great accomplishment, there are center diffs for revo trannys as well that would allow front and rear brakes.........

Except this looks to be about 100x stronger, and looks WAY cooler ;).

absolutely agreed

Looks Great! Any reason why everything is deanodized except the optional motor mount brace?

Because i don't having time to deanodized the motor mount brace yet
I realy don't like the stock blue anodizing!

Speaking for myself I find that the revo center diff is worthless when running a powerful BL motor. Too much power gets wasted due to excessive power going to the front wheels spinning instead of to the ground.

I need to pick up a 1/8 diff to play with to see if I can get the diff action under control. After seeing David's setup I may try something similar but fitted with the center diff.

David, yours is coming along nicely! My only criticism is that you call it a "sliperential", yet I see no center diff . Any plans for installing one?
