For your frame - modifing 2 cheapo engine stands into a rotisserie would be plenty strong and quite inexpensive to do. Extend the tubing that has the 2 casters mounted to it, 36" is too narrow to safely roll a frame on. IF it was me, I would extend that tubing to 60" wheel to wheel and feel comfortable. 750-lb-capacity-engine-stand- $46 Use this 20% off coupon and save some more Last edited by Old Fool; 01-17-2013 at 06:05 AM. |

Build one..Works better and every car body needs some sort of adapter to mount the body to your rotessirie.. so you will need some welding skills to fab up that piece..
the engine stands are a decent start.. Sam

built mine
I found these free plans I googled harwoodperformance, and clicked rotosserie, and made modifications to use steel I had in the rack, I spent $ 35 for new castors and bolts. But i had a lot of free steel. The last body we used it for was a 48 jeepster, no problems, I have a large roll around gantry crane that makes it easier to hook everything up. The crane is large enough to straddle my 6 wheel equipment trailer and tall enough to use if I ever have to pull the engine out of my backhoe again.

I've got a home-built one that I bought for $300. One big question for you other rotisserie guys:
How do you go about finding the center of gravity so it rolls over freely and doesn't have a heavy spot? TIA! Russ |

I had a design of one yrs ago when I back hafted a Monza town coupe and was laying on my back getting tattooed from the slag from the up welds.It was going to double as a frame machine where I could set it up/adjust it for level.I never figured a way to not have to re-level it everytime I would have to move it out of the way.
I have heard of guys building them so they are motorized to turn it and have hydro cylinders to lift it up.That would be the cat's meow!. |

Getting a body balanced on a rotisserie is a bit of a trial and error deal..the adapter is mounted to the body so the axis is centered side to side and then with an adjustable mount the weight is centered in the vertical axis of rotation..When you build yours some sort of pin or brake needs to be installed so you can lock the body in one place while you are working. after one spot is completed then unlock the body and turn it ti the next spot and work on that until it is done and can come off the rotisserie..

eyeball it
do a rough estimate of where you think the center should be. then set the arms to that height , then pull the pin to see how it swings. Re adjust the height of the arms as needed. I could spin the body pretty easy once I got it right. My gantry crane makes lifting a body easy with a chain hoist. and you do need some sort of safety locking device to keep it place.

I have an Auto TwirillerPlus model rotissure. It is a very heavy duty well built unit that has built in adjusters for setting that balance point. I have had the body of a 57 cadillac convertible with doors and trunk lid in place on this unit. It is a very strong rotissure as this is one of the heaviest cars you could possible put on such a unit. I beleive the cost of this unit back in 07 was around 1200 with shipping to a freight depot. Do yourself a favor and look into one of these...............

Here is a roto I have made and used for 2 different cars. It was just an afternoon project. You can estimate your center. When it is off, you lay the car on the side and measure the weight at a specific spot. It is easy to calculate how much the car needs to move. You can modify the roto to change the pivot and your done.
