I got tired of those cheap ass car dollies
You know the ones that go under your wheels, and I wanted to be able to pull a car down to bare body without having to build a rotisserie or having it tie up my lift. So I decided to do something about it. In the thought process I did some research and found something similar to these. So I ordered a set, when they got here they were kinda cheap, and not exactly something I would want to push one of my cars around on and trust. So I figured I would build something bigger and better. They are built from scratch, the only store bought part is the casters. These weigh about 35lbs a piece, each caster is rated at 650lbs. They took me about two weeks to build the first time after work each day. Think I could do it again in about 10 hours. On with the pics, tell me what you think guys.
![]() Had to have a set of 4 of course ![]() ![]() Full height is about 26 inches, could be built to whatever you need if you want to try it. ![]() Fully collapsed height is around 13 inches. Ground clearance at this height is about 1/8th of an inch, so needs to be on level ground. ![]() Locking wheels all the way around, dual grease bungs on each wheel. ![]() Made the tops adjustable to pinch the fold in the unibody on the underside of the car, I'm also making up extra pieces to go in here that will make cradles for use directly on the frame. These open up to 1 full inch. ![]() Duel handle adjustment to ensure a snug fit on the pinch weld. ![]() Some sexy welding, this took a while, ground all the welds out smooth, being sure not to compromise the penetration. ![]() ![]() ![]() |

Please post pics with the car on them, they're sexy by the way. I think this would be better in the fab section wouldn't it. Anyway they look real professional.

Looks really good, I could have used these about a month ago when I was stripping down my old wrecked civic.

Those look VERY nice, amazing job. You should post in the fabrication thread if you haven't already. Nice attention to detail with the weld grinding and paint. They look beefy and seem like they will last a very long time! What welding method did you use to make those?

Thanks guys, I can't patient them, companies already make some very similar called OTC dollies, I just made these a lot better quality then the ones I ordered from OTC first. As for making more, with the amour of steel, price of casters, and labor in them I'd have to get around $550 per pair to make it worth it or I could do a set of 4 at $1000. Like I said I made these beefy for me, they weren't cost effective haha. But definitely worth it to me all day.
As for the welder I have a miller syncrowave 350dx with the coolant option and autopulse. It will do TIG (which I have yet to learn how to do) and stick. I used MIG for the dollies on a miller 250 I have here in the house garage. |

No I'm going to be mocking up the rotisserie once I get it to the point of: No motor, no suspension, no interior, no fenders, no hood, and so on. Then I can do any repair work to the frame, mocking up of the cross bracing I'm going to make for under the car, and other things. I'll post pics of the rotisserie once its done in a few weeks.

Alright, got a really nice day today so I took the new dollies out and put my girlfriends coupe on them. Some of the fold in the under body was crushed by improper jacking by the previous owner so I had to fix that with a pair of pliers first but here is the final result for those that wanted to see the dollies in use.
Here they are on the drives side as far apart as possible. ![]() No hating on my cheap jack, I ordered a nice one when I realized my good floor jack somehow disappeared in the move. ![]() Here is the fit on the underbody, everything held up perfect, no denting or bowing from the car, and not even a creeeeek from the dollies ![]() Here is me under the car on a creeper with plenty of room if I wanted to work like that. ![]() A look under the car to the other side. I can turn these differently to give me more room between them or more room to work around the suspension. ![]() Another picture of them on the folds sitting nicely in the dolly tops. ![]() I actually moved the one towards the front of the car back a little bit as we later took the front of her car off to start her S13.4 Kouki conversion. The best part is, I just told her what to do and she is doing the work. haha Here she is getting her hands dirty ![]() Learning all the fun stuff involved in body work ![]() And now all done and stripped out. The good thing is I even made her drill out her own spot welds. hahaha ![]() No hating on her wheels/setup guys, the car was a ricer/drifterwanabee rescue. And done, let me know what you guys think of them in action. |
