    Rotisseries and e30's

    I talked to a body shop recently about putting my car on a rotisserie to sandblast my car(s) and do other work I want to do. They wanted $100 to mount my car on one of theirs, and a $100 deposit to keep at my place for a month. However, I'm thinking I could build my own for not much more that will be much better, and it will be mine to keep! I have thousands of hours of welding experience, so I know what I'm doing when it comes to that... I'm not going to just use two engine stands connected together, I don't think that's safe at all, and some other plans I've seen seem sketchy to me. Since I don't have a lot of space, mine will be taylored for an e30 to be as safe and compact as possible to fit in my small garage. I plan on using it for future projects, as well as helping out others who want to borrow it or use it as model to build their own.

    Anyway, supporting a car on jackstands or a lift, and having one mounted on a rotisserie are obviously very different. I need input on what the do's and don't's of mounting an e30 on one are, specifically what the strongest points on the chassis are to bolt it to that will keep it from deforming. I don't want to assume that it's safe to simply use the front and rear bumper shock mounting points that I've seen done. I might do some seam welding, and I think it makes sense to make sure the frame is perfectly squared up before doing that. Yet, safety really is the biggest issue here; I don't even want to imagine a car falling off of it and hurting somebody, much less damaging the body because it isn't mounted correctly.

    Any advice would be appreciated!

    I don't think you can build a functional and safe rotisserie for ~$200. Looking online, if you were to buy one pre-made, ~$800 is looking like the cheapest, and that is for a smaller, lower-end one that you would probably want to avoid anyways.

    If you are serious, the first thing I would do is search for plans, look at already-made rotisseries and find a couple people with a solid understanding of basic physics. I would bet you could make a decent one for around $500, maybe a little less, but not $200.

    Also, rotisseries are fucking badddd, cannot wait to have my own.

      I ghetto rigged the shit out of mine.
      I took a 5k engine hoist and a 1k hoist. Got some chain, some bolts... I had a my car in the air about 4ft and was able to rotate it and prop it. Safe? nah. Effective? Hell yea.
      That being said,

      For $200 in materials you're better off bulding a pair of tilt stands.

            Haha sure, I'll have to re-measure a few things but I'm down!

                Maybe I'll put together a little diy. This one is for a late model, and I might be modifying it to do an early model. The only difference that I can see will be the height of the rear mounting point.

                      that is effing awesome. how is this for rotational balance? can you spin the car around with one hand and have it stay in position? it appears the car you have in the photos is a cabrio? that will change the balance point a bit.

                      just so you know, rotisseries have their limitations. they are great for working/welding on the bottom side of the car. they are not good for changing quarter panels or roof panels, etc.

                        No its a 325is late model. Balance is really good, could be a little better (a touch bottom heavy) but thats because of the room i had to work with in my garage. I can still move and roll the whole thing myself.

                          IronFreak, I'd really appreciate the measurements as well!
