1930s dumptruck - Nylint
 

I'd ordered a WPL B1, "1/16 scale" M35 truck kit. It's small. Quick search and sloppy measurement, it appears to be 1/17.5 or 1/18 scale, and looks like a minitruck next to the cars.

Looked awesome, scaled wrong. Might as well make it weird...
Pic i can't find.

I had gotten this 'Nylint Classics' 'metal muscle' truck from my grandma for a birthday some time in the 1990s. They had atleast 5 trucks in the series: Dump, Stakebed, Tow, Fire pumper, Fire ladder.

I shortened up the wheelbase a little, trimmed the frame length some.
Then i put the fixed end of the leafsprings at the outside, and went spring-under axle. Trimmed the bumper off the rear crossmember, and pulled the trans out for now.

Then some internal body trimming, and a little chassis crossmember clearancing. Which got me to this point.

I think this might just work...

Haha fantastic work frizz. I ordered 2 of those but seller was a scammer. Got my money back thanks to ebay. Glad i didnt get them now but its perfect for that truck!

Re: 1930s dumptruck - Nylint
 

Looks great!

Re: 1930s dumptruck - Nylint
 

cool

Re: 1930s dumptruck - Nylint
 

As a 1/18 truck, the B1 is pretty good, but not stellar. As a 1/16 that will play around with 1/14, 1/12 scale...it's a donor.

There are no bearings, there are no differentials. All gears are plastic, looks probably nylon but i don't know. Driveshafts are plastic and the yokes don't inspire confidence. It's very toygrade. It's not a rock crawler with bulletproof drivetrain. These aren't tamiya semis you can let a kid ride on the trailer. But it can give cheap axles to get smaller vehicles moving. The 3D printer guys are going crazy and cranking out new parts weekly.

Anyway, i've always been impressed with the old trucks with how tiny of running gear they had, and just how capible they were. Plus this was the dumptruck i actually wanted to build first, the Structo was made since it was cool and fit the donor axles. I'm not planning on this being a primary dumptruck, but more of the company owners 'Restored Toy' that helped build the company and the owner takes out occasionally to do trade shows, events, and light jobs for fun in nice weather.

I need to make some more leaf springs, i've got single in front, doubled in back. It's still a little spongier than i'd like. I don't need to aim for huge capacity, the trucks only going to carry maybe 1-3 dragline scoops.

There's also a guy on the 'other' board building one of these WPL trucks into a (tamiya lunchbox) Dodge Tradesman, which i think would be fun to do as a 70s 'Vanning' custom. It's a decent little donor if you keep it reasonable.

Re: 1930s dumptruck - Nylint
 

I get what you're saying. Still looks pretty dang cool.

Re: 1930s dumptruck - Nylint
 

I haven't had a chance to get mine together yet. I'm sad to hear they are a lil small scale wise. I am however glad you were able to put er to good use by thinking outside the box, as you're so good at doing. That lil dumper looks absolutely AMAZING!

Re: 1930s dumptruck - Nylint
 

Thanks everybody, i'm glad you're liking the way this is going as much as i am!

Mild lift over stock and offroad tires. It will need some foams in the tires.

I know 4wd wasn't much of a common thing until after WW2, but there were some aftermarket companies doing it, so i'm not sure which way i'll go.

Looks like it fits right in. :)

Still needs work. Working on Mk.2

Mk 2 and mangled mk1
https://i.imgur.com/wBOOrAih.jpg

Servo height sitting on top of mount is pretty good, doesn't need the mount slot, i couldn't dig out the support matrix anyway. Dimentions and everything above clear the body great.

I quickly realized when i spec flat bottom on mk 2, i forgot about servo arm swing, and diff pumpkin clearance. I'll get it pulled back out and send pics and cutouts.

I made servo drag link out of copper again, ran to right tire which clears better and to minimize any bumpsteer through my "massive articulation". This is temporary, unless it works.

Re: 1930s dumptruck - Nylint
 

Very nice work on the servo mount design. Looking forward to see the final iteration. Do you have any plans for building something with the new WPL 6x6 chassis?

Re: 1930s dumptruck - Nylint
 

I'm just glad that I'm getting help from igotit over on scale, and my friend with the printer.

I don't have plans yet. I've got several things already in work i'd like to finish first. If i do get the 6x6, it's probably going to be an M35A2 as scale and detailed as i could make it. It's small to play with Tamiya semis, but looks really cool.

That looks awesome, Frizzy!

Re: 1930s dumptruck - Nylint
 

I figured out a mid body mount using a plastic strip and screw into an existing rivet hole. So the frame sockets onto the bumper extention, lays into the body watching crossmember location, then raise the plastic strip and rotate it across frame. Good enough.

Let's run some vintage equipment

Yes it pulled the Unit Crane. This one time. No it wasn't safe. It took ALL the truck had to pull the crane, motor smells hot. Only my 4wd Structo will be used to move the little Unit.

Re: 1930s dumptruck - Nylint
 

Moving high volume payload isn't exactly the priority with this truck.

https://i.imgur.com/VIOV4LWh.jpg

It takes a little more Accuracy hitting the bed with a load. Plus no cab-protector at all.

https://i.imgur.com/cdahEsJh.jpg

Chrome will Always get ya home, and i ain't kidding!

I'm kinda going for a Truck that started the business when new, they moved on, it came out of storage for a restoration, and sometimes gets lightly used more as a retired toy than a working truck

Due to the small bed and soft springs, it won't really 'Ride like a Dumptruck' and the little Figrelli / Actuonix bed actuator i got that didn't work for the bigger truck seems like it can pretty easily handle things on here.

Figreli L12-30-100-12S


Its able to dump a 12 oz beverage can. I think that should be about right for a load of dirt or crumb rubber. It doesn't have a tailgate so it's not like it'll get filled to Struck or Heaped.

I'll probably still add to the suspension limit. A little over a 12oz can in the bed is about where its either still up, or squats the shackles to the stop. If i upgrade, i'll probably just try to break some toy spring-motors to make some extra leafs.

Full up dump.

Re: 1930s dumptruck - Nylint
 

Sweet looking!

Re: 1930s dumptruck - Nylint
 

Thank you tgrzes!

Somewhere along the way this also got a leafspring upgrade with aluminum drops & shackles, and added more leafs cut from stock slider springs.
I also bumped it up to a newer gearbox with 180 motor.

Re: 1930s dumptruck - Nylint
 

WoooooHoooo a completely working dump truck....!!!!!
looks pretty good now lets get that Nylint working lol :D

Re: 1930s dumptruck - Nylint
 

Oh man... "Completely working" ? I just said now it can drive, steer, and dump.

Next you'll say i should still make a 2/3A battery pack, get an Rx and 2 Esc in there. Probably do a little bench seat interior. Maybe do some headlights and taillights.

Then you'll probably even reccomend a better motor over the 'Nothing-Special' 180 upgrade i already put in there. Something like:

Re: 1930s dumptruck - Nylint
 

:bounce: Hey that's a great idea..!!!!
good motor by the way you have excellent taste :D

Re: 1930s dumptruck - Nylint
 

I heard it was a good motor, over on another site a really talented builder suggested that one.

Re: 1930s dumptruck - Nylint
 

I used a 180 can motor like that in My Bruder Ram a Ninco NC2 they are out of production now the one you mentioned is one of the replacements. It's not super fast but it drives my Ram pick-up and pulls a trailer with my D5 on it and it weighs about 5 lbs and I'm using the same WPL gearbox

Re: 1930s dumptruck - Nylint
 

Sweet, that sounds like it'll be more than plenty of motor for this little truck. It should atleast get me up toward the axle-snapping and upgrading to metal diff housings stage.

What size esc are you running for it?

One should get me through this truck, and sounds like probably have enough for powering the Michigan Crane carrier.

Re: 1930s dumptruck - Nylint
 

It should be ok for that small a truck
I'm thinking the crane carrier is going to need more than a 180 can motor
I used the plastic axle housing with metal innards and the cheap 30a esc

Re: 1930s dumptruck - Nylint
 

This truck is pretty light, only cab & bed are steel. (Toy safety in the 90s ment less of the rusty & jagged steel i seem to like.)

Realistically I'd really been thinking more like one of the 370 motor gearbox for the crane carrier, or adapting something that's gonna be way WAY too big...perfect.

Plus a guy upgrading a couple of WPL rigs to Do Work might also unlock a couple of 'Bonus Trucks'...

Re: 1930s dumptruck - Nylint
 

I've down loaded a dual 370 mount for a WPL and a 550.. I want to experiment with them

Re: 1930s dumptruck - Nylint
 

Man that lil truck looks SHARP!

Re: 1930s dumptruck - Nylint
 

Thanks skeeter! I'm really happy with how it's coming along.

Bench seat, not sure about adding lights.

I'd been kinda looking at some of the Steelie or Spoke style wheels, but none quite do it for me. The Jeep or Toyota FJ aren't too far off

If a guy builds a dumptruck, it's kinda nice if the bed actuator motor is set up so ya can disconnect the Dump from ESC, plug in a battery pack and it drive the bed up for cab clearance.

Re: 1930s dumptruck - Nylint
 

Ya ever take a model to an rc meet hoping to drive around on some roads, and move some crumb rubber?
...then after you've been over there a while, realize at some point you had borrowed the Rx and Escs to put in something else. Yep. Really smooth.

I've been staring at the truck for years, trying to figure out what it is. Now i'm kinda leaning a little more 1926-32 instead of 1930s?

Ford AA
Mack BB / BC / BF / BG / BJ / BL
REO FA

From what i'm seeing, it's likely in the range of 1 ton to 1-1/2 ton payload, but could possibly be up to 8 tons?

Re: 1930s dumptruck - Nylint
 

I think it needs smaller tires and more "period" looking wheels...
check your email.....

Re: 1930s dumptruck - Nylint
 

Yeah jerry i know those wheels aren't very period, but they fit the lug pattern and the tire shop was willing to mount tires on them. It kept the diffs from dragging the ground.

I know you've mentioned WPL and Lego tires. I'm assumung your Street tread is Lego 62.4x20s, with Offroad tread being WPL sized?

I don't think the attachments came through correctly with that email?

Re: 1930s dumptruck - Nylint
 

Yeah the Lego's are my "street tire and the WPL "rock tire" (it's what they call it) is the off road, they are smaller and narrower than what you have on there now.
I'll check that email...

Trying out something Old, or New. Nice.
I need to lower it more. It's already Spring-Under. Going to need to stiffen the leafs, longer eyes, or add a leaf. Probably do some lowering blocks also.

But why are split-rims only a vintage thing?
https://bangshift.com/general-news/v...heel-mounting/

My friend printed 2 Single wheels, then nuked the hot section of his printer trying to print a pair of dually rims. Turns out this truck can only run singles.

Re: 1930s dumptruck - Nylint
 

Looks a lot better....just need a little paint green and black....
The WPL rock tires and a little smaller if you need to go that route....
I double up on the WPL springs and put the little plastic "helper" springs on...
Worked in a garage as a kid... NEVER put air in a split rim unless it's in a cage.... If it does blow off you'll survive but you'll need clean clothes because it sounds like a bomb going off...right in your face

Re: 1930s dumptruck - Nylint
 

Thanks, I'm pretty happy with wheel size now. Fenders aren't as stuffed, and should be a lot easier to keep from rubbing with suspension travel.

Yeah, i know the split-rim wheels i work around have something like a 15psi (temperature-adjusted) window where you can change nitrogen pressure while it's installed on axle. If they're out of range on the chart, gotta vent it, pull the valve core, and send it out for overhaul.

Green & Black might work. I'm not real sure on a color plan

To help lower the truck even more and bring up the spring rate, the spring eyes were stretched farther apart at frame attach points. One of the cheap wpl B first gen axle halves has broken, and the plastic spring spacers are falling apart. I should probably do some lowering blocks.

Picked up the professor motor tuned 180 motor jerry suggested. Nsr 3015 King balanced monor 38,500 rpm 310g-cm torque. Their picker didn't seem to like my order-comments, or maybe they didn't feel good in their skills of an artist to Draw a Dragon?

That jungle-website finally decided (after a couple tries) i could get some parts Delivered. So this gets (2each) 30a esc, and 6ch rx.

Current Goal: have this ready to run, so it can just sit outside in the big car for the Toy Truck Show when i find out the "rc toy trucking" demo thing actually isn't *THIS* group, and i that can't play with them...
Maybe try to terrorize some hallways anyway, get kicked out of the hotel.

Re: 1930s dumptruck - Nylint
 

Those wheels look a little more "period" ... and lowering it would help the look too I think those shackles make it sit up pretty high
I found these the other day...

https://www.aliexpress.us/item/32568...yAdapt=glo2usa

I think I might order one or two just to have on hand they look "handy"

Re: 1930s dumptruck - Nylint
 

I agree, a shackle delete would be the easy way to lower the truck.

It should be fun watching the modern Hydro equipment trying to load crumb rubber into my truck. Maybe 1-2 scoops...

Nice looking gearbox, i'm sure you'll find some really cool uses for that.
