Looks like it's coming together fantastic....
Love these builds I DO..
Front axle work .....Supper cool.
Rear axle...Sweet Idea... might be stealing some of that, yup.

6x4 would be be over the top, But I also like the looks of the "Mud drag racer" with those tires used ... could be a sweet theme.

Keep it coming.

Default Hairball's T-bucket

All in favor of traditional T-bucket say "aye".
*cricket chirp*
All in favor of crazy 6x4 T-bucket say "ZOMGWTFBBQ!!!11!!"

Dang. Ok. Time to get cracking then.
We're going to be 4 wheel drive now. Can this be moved to 1.9 please?

So Saturday was a busy day. Deciding over the top crazy 6x4 meant I could play with trying something I've thought about doing but never have.
It started with pulling out the very first crawler I ever built

Based off a mini LST with dual gear motor drive, two full size servos, and a custom chassis with a lazy Susan bearing in the middle


A piece of spring steel on the bottom acted like a slick skid and limit spring for the bearing
Stampede wheels, narrowed, and Moab tires with BB's rounded out this 2006-7 project.
Today I robbed the chain drive off of it.


One of the sprockets had been drilled out to 8mm, I found a piece of rod and made a bushing to get to 5mm


Then clearanced the head of a bolt so it wouldn't hit the roller chain while playing the role of set screw.


Added a couple of chunks of 1" square tube and a Wheely King knuckle to support the end of the xc01 driveshaft.




Added some vertical supports for the upper sprocket


Chain, sprocket, WK knuckle, Jugg driveshaft.


And of course the WK transmission attached to the end of the Jugg driveshaft.

McMaster Carr, the chain is #25 stainless I ordered one foot of it and two small sprockets using the work account at the old job.

Just enough room for a u joint and the straight WK axle.


My frame was going to be short so I added some extensions


Went with rod for the cross members


Starting to get the rear transmission lined up


Made a couple of side plates after narrowing the trans mounting tabs to make it about knuckle wide.


I've been doing everything freehand holding up metal and referencing where to cut it with a thumb nail then taking it to the bench vise, holding the thumbnail "about a blade width" above the vise, and using the vise jaws as a cutting edge for the sawzall
I actually measured here and was 46.5mm on one side, and 46.9 on the other inside frame rail to transmission side plate. I'm impressed. I was hoping for "kinda centered"


Welded in a couple of struts to hold trans in place. Did this with the knuckle and trans mounted, just used a bottle of water to cool things off quicker after giving it the zap.


Another look at narrowing the WK axle, second one.


Looks a little better than the first.


Starting to look pretty good.







Here's how it sits now. The straight U-joint to trans is going to be really weird trying to make suspension for. That's the next challenge. I may end up making the trans rigid with the axles and put the pivot up high like a rail truck. We shall see.

Haven't given up yet. Got busy with monster trucks again. Scrapped my ideas for trying swing arms for individual axles. Decided that since I had the radius arms up front, I should do some out back too.

Pulled the wheels back off


Started bending up some rod


Welded on some M3x20 bolts for rod ends.


Put the wheels back on.
Not really digging the gold wires.
Thinking about something else.


These look better!


Had to redo the rod work to clear the deeper offset wheels.


That's starting to look interesting.

Huge tires fit the bill for sure.. Moe better.
I think your on to something doing rear radius arms too.

Liking the new direction and looks even more.
I need..yes, Need to see Vid of this once up and running..Going to be supper cool.

I like just looking at it....aahhahaaha ..Draws the eye in and on it.
Keep the wheel and tire choice for sure.

Thanks for the feedback, it really does help. I got one side down and one to go. Then will be getting the servo mounted and figuring where to hide the truck go parts

Got some work done this morning.


Knocked out the other side rod.


Mandatory flex shot. Almost 2-5/16"


This will be interesting to see how well it works with open diffs


Put some rear shocks on to help do something.





This just looks so good




Tried something. I don't think the bed will work.


A work bench you can clean with an angle grinder is so underrated.
