Building a Bouncer
 

I've decided it's time to build a rock bouncer, have loved the look of them since I found out they even existed.

I will be using AR60 axles, but the rear will get converted to a center pumpkin, so I need to order another housing.

I've decided to try a 1/16 Traxxas transmission, with some custom set screw/pins and shims to take up the gap as the outputs are 4mm, and the shafts are 5mm WB8 HD's. Nothing some 0.019 aluminum can't fix.

I'll also be going sensored brushless on this one, for a more authentic bouncer feel, haha. I'm thinking a waterproofed MMP from Holmes, and a Tekin ROC 412



Got a long way to go, but I'll be using the 1/4 brake line again for this chassis.


Now to name it, hmm

Great start! I like the 1/16 tranny.

Re: Building a Bouncer
 

Made a full scale side view to plan things out, and got the chassis started.

After all the aluminum brazing I was doing in building Slimer, brazing steel is a cake walk! And about 100 times faster!!

Re: Building a Bouncer
 

Nice start! I really like your hand renderings.

Re: Building a Bouncer
 

Thanks guys. I can't take all the credit on the idea to use the 1/16 Traxxas tranny though, grunt95 suggested it in a conversation about building this rig last weekend at the snow crawl, before I knew what size tire I was going to run. I was debating between 1.55, 1.9, and 2.2, obviously I went 2.2 though. Hopefully it holds up, but I've seen metal gears and cases for them if it comes to that :mrgreen:

Re: Building a Bouncer
 

Really like the looks of this !!! like the tranny idea also. As for a name...... I cant come up with many other names that don't evolve some type of spider theme. the overhead view resembles a spider body very much..... hmmm

Re: Building a Bouncer
 

I'm impressed with you drawing skills nice work. They clearly show the direction your heading with this build.

Re: Building a Bouncer
 

Guess I could just call it something fairly tame, like Webster, haha

Re: Building a Bouncer
 

Interested to see the trans do work. It looks smaller than the axial direct drive setup.

Re: Building a Bouncer
 

Got the mounts for the tranny made and brazed in. Ah, steel is so much easier and faster to braze than aluminum, haha

X2!!
About to start building a similar truck. Keen to see further chassis construction for some tips :)

Re: Building a Bouncer
 

Got a couple more pieces made and brazed on. I set a few thing in places they might end up, but I think the battery is gonna go up front, and have all the electronics out back.

Name it venom. Looks like a snake head "thumbsup"

Re: Building a Bouncer
 

i like it!

Re: Building a Bouncer
 

how does one do the transmission conversion? :mrgreen: x2 on venom

Re: Building a Bouncer
 

How did superdrty like my post twice?? O_o

Re: Building a Bouncer
 

He's brazing words now.

Re: Building a Bouncer
 

I have no idea how I liked your post twice, haha, that's odd, but funny.

I got 3 more pieces made and brazed in, and you can start to see the shape its going to take on.

Also got an idea sketched down for a engine/cover to help hide the motor and battery. TT LS. I'll probably just build it out of styrene.

Nice drawings, just a shame reverse rotation turbos aren't that common
