Re: ~1:12 Miller Century M100 Rotator wrecker

Thanks for the good words.

This was very much a "Might As Well" build, as in, "If I'm going to do (x) I Might As Well do (y)." I think I just really like the big tators, and wanted to do it right....

Re: ~1:12 Miller Century M100 Rotator wrecker

Thanks for the good words. Time-wise, been drawing this up for a coupla years on and off, lot of off. Actual assembly, few months. Joy of being semi-retired. Once I had a plan it's not so bad, other...

Re: ~1:12 Miller Century M100 Rotator wrecker

Thanks! I started out on a track to become an EE, got sidelined into software, but always enjoy electronics as a hobby. Which might be obvious her e=))

Re: ~1:12 Miller Century M100 Rotator wrecker

Thanks, yeah, tons of electronics, but that's something I enjoy. Mostly.

Not sure I follow the Q. Each board has plugs on it, color-coded and the wiring harnesses are color-coded, either by wire...

Re: 1:12 scratch trailer(s) for the Purple Nurple

Thanks. Having fun, key thing. And I can stack the conex trailer on top of the flatbed and still have room for another trailer on top =))

Wrt the Arduino, two reasons. One, I had some laying...

Re: ~1:12 Miller Century M100 Rotator wrecker

Finally, while a lot of tator operators use them purely for recovery and have a dedicated truck for towing, I wasn't gonna build a second truck just for the underlift. I have finite shelf space and...

Further indication of So. Many. Wires.

Inside the cab, one ESP32, with two DRV8833's for the underlift and a bunch of jumper points for the lightbars, and the ESC for the motor (you mean this...

Other random bits. Front axles are limited and ratio'ed by a baby Arduino (blue in pic), ie the frontmost turns more than the second.

Re: ~1:12 Miller Century M100 Rotator wrecker

As we know from the HEMTT, I tend to make my builds my way, mixing and matching, but since these trucks are bespoke in the real world, this one doesn't so much take liberties. There are some places I...

Re: ~1:12 Miller Century M100 Rotator wrecker

Now, what to put in the boxes? I opted to take some guidance from the 1:1 above, which I'm sure is a Miller showcase of everything they sell and not necessarily a realistic example of an actual...

Re: ~1:12 Miller Century M100 Rotator wrecker

As always, the devil is in the details. Wreckers in general, and crane ones particularly, have to carry lots of tools, equipment, and accessories to cope with whatever situation they encounter. This...

Re: ~1:12 Miller Century M100 Rotator wrecker

Part of the reason there's so many wires is the ridiculous number of actuators and servos, but also lights. I like lights. A lot.

There's some spotlights by the winches

Re: ~1:12 Miller Century M100 Rotator wrecker

One thing I discovered is that on many rotators, the crane doesn't just rotate, it slides. Yep, in addition to rotate, lift and extend, the dang moves about a third of the length of the truck. Makes...

Re: ~1:12 Miller Century M100 Rotator wrecker

Outrigger design sorted, next up was the crane proper. It's much like the outriggers, telescopes, but has three actuators rather than two and lightening holes.

Re: ~1:12 Miller Century M100 Rotator wrecker

Even with modified firmware, a traditional TX just won't have enough knobs & switches to control a beast like this. I opted, then, to graft an ESP32 and an array of switches and rotary encoders onto...

~1:12 Miller Century M100 Rotator wrecker

I've always been fascinated by the tow trucks for big rigs. The biggest of the big is the Century M100 rotator crane truck. For instance, a coupla 1:1's:

Re: 1:12 scratch trailer(s) for the Purple Nurple

Some time ago I'd made various shipping containers, conexes, whatever you call 'em, for my M1074 HEMTT/PLS (https://rctruckandconstruction.com/showthread.php?t=13835). It was always my intent to make...

Re: 1:12 scratch trailer(s) for the Purple Nurple

Already making some changes from lessons learned from the next trailer. Went to wider axles (167 shaft instead of 140), which look better in person but forgot to photo.

Re: 1:12 scratch trailer(s) for the Purple Nurple

Thanks! I was gonna say "It's my first trailer", because there's stuff I'd do differently the next time around ... until I counted and realized it's my fourth trailer =))

Re: 1:12 scratch trailer(s) for the Purple Nurple

Thanks, and I think part of why I didn't bother thinking it thru is that I have a shelf (actually cabinet top) in mind, which is like ten or twelve feet long. Already has the HEMMT on it, mind you,...

Re: 1:12 scratch trailer(s) for the Purple Nurple

Huh. Shows you how much attention I pay to trailers -- and my wife complains because I snap my head looking at semis when I'm driving =))

OTOH, in this case that might be a good thing, other than...

Re: Purple Nurple: ~1:12 Frobeliner cabover scratch build

Also occurs to me that doing 1:12 allows me to fudge using parts from both 1:14 and 1:10. Gives me a little more leeway in what Chinesium parts I can use/repurpose.

Re: 1:12 scratch trailer(s) for the Purple Nurple

And of course we gotta have lights. Dang near all my projects have lights, lots of 'em. That rear bumper, like the one on the Frobe, has translucent filament insets with LED's behind.

In this case...
