Rotisserie build

65-408

Member
If anyone is interested, I am building a rotisserie. I was able to get pretty much all the tubing/material from the scrap pile at work. I think the only thing I had to buy is the hydraulic cylinders ($30 each at harbor freight). Here is the CAD model:

Here is the outer pivot, it was a loose fit, so I cut some sleeves from some 2" exhaust tubing, welded them in and bored the ID:

Here is the inner pivot piece with the groove cut in for the thrust bolt:

And here is my newest tool, a Dake 25 ton press that they were going to scrap at work. Got it for the scrap price, it just needed a new leather packing (and a good cleaning). I built the little press brake frame for it. Here it is bending the 1/8" thick steel C-channels, only took about 5 tons...

Nice looking build, did you make your own plans or purchase them? Nice press you got that was being scrapped.

Safety lock/bolt in there somewhere in case of a hydraulic failure?

Not sure on the through bolts yet, but it is not left on the jack. The clamp plates are 1/4" think and will squeeze on the tubing with the force of (2) 1/2" bolts. So it is held with friction, and a whole lot of it... I will test it once I have it together to see if it is enough.

My design around the tubing pieces that I had from the scrap pile...
 
Nice build! Some locking casters or some type of jack bolts to stop the whole thing from rolling on you might be nice.
 
Here are the completed pivot assys, they spin easy:

The bases:

And the cross bars:

Just need to wait for some 1/4" plate to end up in the scrap bin for the clamp plates...
 
Nice work, the only thing I would consider is lowering the attachment points. I have learned that "if" you can attach and remove the rotisserie with the wheels are on the car it saves a lot of work especially when test fitting an engine. Mine is close and if I would lower one gusset it would go down another 4 inches to do that. Also make sure the jacks have enough travel to lift the car enough to be able to flip it over. I used a farm jack with a 48" travel. It also can be mounted low and has enough travel to easily lift the car high enough to flip. Just something to consider.

OH, when raising the car I keep a safety bolt just under the jack head and move it up as the car goes up. If the jack fails it can't drop more than a few inches.

Test fit, goes together easy and the clamp plates work really well. I wanted to be able to break it down for storage, so it is nice that the vertical column can come off the base.

Here is the pivot with the clamp bolt (have to get a shorter one) to lock it in position, not sure if friction will be enough here, we'll see how it works.

Just have to make a pocket for the lift cylinder to go into.
