Short update, got a little more done on the Cracker Box and got the dump body mounted on the trailer frame with the lift motor and mechanism working. Need parts to finish it up. Got to pick up some suspension parts and tires. Here's a shot of where the cabs at.

Thanks Terry!

Besides all of the photos on the internet I found a spec brochure that has profile drawings with the over all dimensions and expanded the drawings in my copier until I got the dimensions according to scale and went from there, you have to start with good drawings because they become very pixelated as you expand them. if I'm happy with it when I'm done I'll build a dedicated chassis to the proper wheel base and see if I can find nice spoke wheels and other period correct details for it. |

Here's a reason why I built a dedicated test chassis. I bought one of these motor/planetary drives, 437RPM @ 12v. The volt range on the motor is 6-12v so I ran it off my 7.2V battery realizing it would be a little slower. It was actually to slow however smooth and controllable. So while taking a break from other projects on the bench I started playing with some stock cans I had laying around and found that bolting this Axial 27 turn up to the planetary gives me a good top speed and plenty of power. The true test will be going to a meet and load some construction equipment on it. Surprisingly I haven't found a less expensive alternatetive to replace the 3spd with. Buying new, the 12v planetary combo is $40 & the 27t Axial is $14, just need to figure out what to do with with the extra 12v motors down the road.

Kent,
I just picked up one of the servo city gear motors to try in the wrecker to save space over the 3 speed. Very nice looking unit, but I have 1 question. Did you pull the stock pinion off the 12v motor and reuse it as the picture appears or go to a different style pinion? Thanks |

Kent lookin great. Nice details - headlight buckets and the relief cut top center look good.

I have 3 trucks with the 437 rpm planet motors I like them a lot . I like the speed and they still have enough power to pull my grandkids on my Flatdeck . What to with the trannys now

Yes I just slid the pinion off the servo city motor and pressed it on the 550 I used, don't care for that type of pinion but its worked running around in the house so I'll run it until it fails. Quote:
Mike, I'm in the same boat but i'll figure something to do with them. What battery are you running with your motors? I just run 7.2 nimh and they seemed a little slow since those are 12v motors, that's why I swapped the motors, made a big difference. |

I'm running 7.2 batteries just like you haven't tried motor swap yet. But I can't play outside yet too much snow still .

We haven't had any snow to speek of just a lot of rain, been doing all my test runs in the basement. Let me know what you think when you get a chance to run.

Thanks for the information Kent.
I'm planning to swap out the 12v motor for a nice 27 turn 7.2 motor I have on hand. I tried 12v motors in a tank on 7.2 volts down at Danville back in the day. No power and way too slow. |

I can't test in the basement too many trains in the way ! And this weekend we are getting 3 inches more snow !

Kent - busy, my free hand is for turds as well. Grab a straight edge or I like to pre score using my calipers. Kind of hard on the tool but they've held up.
