Default Structo dumptruck + Redcat Everest 1/16

Every construction company needs a haul truck, and it's much cheaper and easier to start there than with the excavator, or bulldozer, or the rest of them.

Here's the plan




I ended up with a mid-1960s Structo Hydraulic Dump Truck. A 1/16 Redcat Everest crawler is donor, axles were shaved and plastic melted and pushed to seal up some holes. I made the structo tires into pin drive, and retained the hubcaps and whitewall rings.

Added a set of Tamiya leafsprings that were longer than i wanted, i think it was the truck set instead of the semi. I curled sprung eyes on the 'b' spring to make a short enough to be main spring up front. I had wanted the rear axle further back, and less lift all around. Tuning leaf springs in a whole different animal, it's mostly in the shackle.

My body mount is pretty slick in how blindingly obvious it was. the cab and chassis were originally riveted to the frame, and after i spent way too much time trying to reinvent the wheel i realized i was being stupid. I stuck a bolt and nut through the bumper and cab and tightened that, those slide into the rivet holes. The back of the cab is located by the original tabs fitting in their slots in the chassis. If i need more security at the back, i'll make a magnet bracket.

trans


body





The body is steel, the chassis is steel, the bed is steel. The weathering is real.

I had to be a little abusive to the interior, but i'm hoping i can come up with something to look right in a 1960s work truck to cover the transmission protrusion.

I cut some corners in several aspects of the design, but i'm trying to make the "toy trucker indy show".

I admit it's not quite up there with the c&c milled, hydrocut, 3D printed rigs... but it was made with a drill, angle grinder, and files.

The dumps not working yet, but it atleast a truck.

I have always liked the home built by hand builds over the cnc milled/ printed projects. Good work man! Some smallish 1.55 wheel and tires would look good on that and offer alot more traction

That'd probably work really well, but the OD on my tires is 2.3 inches. I didn't see a whole lot of options that would keep a working truck look instead of going all highrider on dubs look.

I was thinking that my best shot would be a set of lego tires on custom rims like this build. http://www.scale4x4rc.org/forums/sho...ighlight=tonka

Bottom view



Got the interior back in. Trans clearance wasn't as brutal as i expected it to end up.



I know by the stunned silence you've all been wondering who would run such a modern, immaculate, classy, and well preserved vehicle in their fleet?



I'm ready to hit the meet!

I picked up a Helion (4300 rpm) 370 motor to replace the stock 260. So i moved up from an inline 6 to a flathead v8. It took making the motor mount holes ugly ovals, and a little file work on the skid mounts, and taking a ridge off the side of the trans.

Stock pinion is 14t, to 61t spur. not sure about 3 gears in trans. Axles are 14t pinion, 38t ring

I also picked up a delrin cutting board to use as spacers for a t-case drop.

Power and speed are up, and the driveshafts run a little smoother. I still need to redo the wheel adapter bushings, but it's getting better to drive.

I ran across an rc demolition derby video on youtube that mentioned Traxxas 7378 rims/tires. Its 1/16 scale stock car racetruck steelies, they look like 15" rims with fake tire sidewall. 12mm hex, 1 inch / 24 mm wide, use 1.9 tires, 2.5" tall tires. Yellow letter goodyear tire sidewall.. uses 24 / 26 mm tires from the buggy or rally cars.
7377 is bare rims.
I'm going to try checking into them, it's probably easier than getting custom lego tire rims machined.

Or i could plasti-dip or liquid latex these stock tires and see if that helped traction any.

Traxxas 7378 wheels, smoother running and not 1960s hard plastic. But not sure they're heavy duty looking enough.

Black rims look bad, and should feel bad.



Heres the new rims with some color on them. Argent, like rims should be if it's not a steelie or chrome.

Also got the t-case dropped lower so the drivelines are smoother.

It's still fun to play with your toys with someone else.

Not great pic, and i've got my 1970s tonka sandloader trailer on the back.

I've got a 70's style nylint dump you're convincing me to get started on.

Search around on the toy collector sites first, see what it is, and if the collectors need it more than you do. I've got a nylint lawn-care truck set that's worth around a grand, so make sure it's not worth crazy money to them. Steel trucks are awesome.

Yeah. I know some of the steel trucks are nuts. I picked up this one at a thrift store for $7. It was too narrow for tlt axles and I shelved it. I may have to revisit it and come up with a parts list.

Ok. Been so long it's actually a tonka. I got it for $1.49. And it's a plastic chassis with a 2001 copyright now that I'm looking closer. Which means zero concern about cutting it up.
Track width is 5.5-6" range, looks like 8-8.5" wheelbase. My tape measures are next to my 10mm sockets.

Oh yeah, I've got one of those i picked up for maybe $5. Right now it's in pieces with a couple coats of purple paint, and will be getting silver or gold flames.
Honestly, who puts a sunroof in a work truck that will have overhead loading?

It's about the same size as my Structo, bed is smaller. I'll try to grab comparison shot later.
