She runs!!
Blink Blink :shock:!! I can not get over how cool this build is.
What else need to be done before its complete?
A good bit. Drive train, shocks, electronics, interior, roof rack, accessories, lights, finish the body just to name a few
I gotta say, your work always amazes me! Every build gets better and better. Great job on the Willys. Can't wait to see more!"thumbsup"
I might have to give the metal body thing a try, I love the damage!!!
That means a lot coming from you! Go for it man! I'd love to see what you come up with8)
holy hell, i was out of rc crawling til i saw this"thumbsup"
If I can pull just one more person back into the fold mu job is fulfilled! :ror:
Well here is an update!
I finally got to working on the tranny. I saw some people here use planitary gear drives from cordless drills so Luckly I scored one from my old man and promptly tore it apart.
I had to cut the drill chuck off the tranny as the screw was seized.
the nice thing about this drill is the planetary gears are all metal and pretty large
I knew it would take a significant amount of modifications to get the tranny to work in the truck.
The first thing was changing the functionally of the tranny. the drill originally had an adjustable clutch on it. this worked by a ring pressing on a series of two bearings
these bearings resided in the holes in the back of the tranny
which in turn engaged the tabs on the end of the planetary ring.
reducing pressure on the outer ring caused the planetary ring to skip past the bearings providing the ratcheting effect. This posed a problem since i have no means to apply pressure to the ring to lock the tranny. To solve the problem I took the planetary ring and positioned it so the tabs were engaged in the holes in the case.
then I took the ring from the outside and turned it down just enough to fit inside the case
the provided enough pressure on the inside to lock up the tranny.
the next item to tackle was attaching the tranny to the T-case. At first I thought about running a coupler between them but space was short and after thinking about it a while came up with a simple solution. I took the output shaft from the tranny and milled the end flat, then I drilled a hole the same size as the input on the T-case, I milled a flat spot on the shaft and finally drilled and tapped a hole for a setscrew.
I knew I was going to need space for the drive shaft so i chucked the tranny up in a cheep X - Y vice i have and milled some clearance for the shaft.
It's not perfect but it will do
Now to mount the tranny in the truck I drew up a plate and cut it out of an old road sign
the whole thing assembled makes a nice compact unit.
I mocked the assembly to get a feel for how it will fit
for the front I made up some small tabs
then for the rear a made some plates to mount the T-case
Here it is all mounted
and here is the clearance for the front shaft which worked out well
At this point i was desperate to get it running so I quickly added tabs for the steering
I was a little to anxious and placed them wrong, as you can see here the pitman arm interferes with the tie rod when the suspension cycles, I really had no choice as the motor is right behind the servo but it will do for now.
Here she is all ready to rock!
I threw in some electronics and took her for a spin. It still has the 550 that came with the drill tranny so it's a bit slow but the gearing is awesome and with a 7 turn or brushless system it should be perfict!
