Help with making rotisserie

[Jocigar]

I have gathered some good info on this in general.

I plan on making an ebody only rotisserie, since I have a few of them in-line.   

Question; rather than making the hieght adjustable on the swivel neck, can anyone give me the correct hieght for both the front and back to achieve clearance and good center of balance.  (using straight couplers with no drop)

THanks!!

Measure across the back of your car from side to side for a full measurement, then half that measurement, that will give you your height, add a little more for ground clearance, job done

[Jocigar]

thanks,

I believe there should be an elevation change from the front to rear for properly balancing the body ?

I used the bodyline for reference. Mine was a tad heavy on the bottom side so I would centre it about 2" below the line, front and back

Try a site search on this subject.  It has been covered pretty well more than once.  I built my own and it worked perfectly but I don't remember the numbers.  My measurements, and others should be found through a search.  I still have my rotisserie and it is available at a very good price if you are anywhere near Olympia, Washington.  PK

Sorry if I am not catching on, do you level the body line? 

if so, then the front overall elevation will be lower than the back, Correct?

[dutch]

yes.  on mine, the turning points were in the centre of the body line. Worked like a charm. I built it with fenders on the car.  use a piece of tape along the front ( and rear) of the car,  taped to the centre of the body line on both fenders, it`s easy to position the turning points that way.
As said, if I had to build another, I`d place the centre 2" below the line this time. 

One more thing to consider;  it`s a lot easier to fit all sheetmetal if there`s enough clearance for the front and rear valance to fit.  There has been a thread on the matter a while ago.

    I don`t know what you mean ..?   the axles you use to hang the body onto ,should be level with the lower connecting beam / floor, and must be inline with eachother. That way the body will always rotate smooth, no matter how it hangs... That body line just was my guide line.

[Jocigar]

You are correct, the two stands must be in-line to each other.   

Since I wanted to make the hieght non adjustable I thought I need to make one shorter for the offset.    I guess I need more coffee today!

I want to make it as simple as possible for cuda frame only,  I will make both same height  and use straight connection in rear fork and have a fixed 5" drop in front fork... sound good??

something like this but fixed hieght and more beefy.

the two stands must be in-line to each other. The rear will be attached straight to the rear cross member using the bumper holes.  The forward stand needs to have a drop fork of about 10' in order to bolt to the frame rails.

The axis of rotation must be on the same line, hence term "axis of rotation".  Having them offset is analagous to a bent crank which does not spin well.

The cg is fairly close to a horizontal line thru the gas filler hole.

If you want I can measure up my rotisserie for you.
I made it to fit my cuda, and it fits/works perfectly.
The body shell bolts on via the bumper mounting points.
The front attachment is the same unit I use for towing my car, just flipped upside down and the towball attachment swapped for the rotisserie attachment.
It has a simple system for balancing the shell.
I also made a couple of telescoping legs that bolt on to the front leaf spring hangers, so you can jump inside the car without it spinning. Very handy!

Have a plan how to get it down once you are ready. I did not have adjustment up and down. Ended up calling the towing guys with the airbags...

[dutch]

I made a different construction to get the car on and off the rotisserie. I used 2 solid square bars 1,5x1,5" as stands. The bushings that hold the axles are sliding up and down between them. I only needed a floorjack and a block of wood to get it up and down.  I used a steel motorcycle chain sprocket with a steel pin to secure it in any position.

THanks all for the help !!!   Nice thread... pictures are great.

Thinking of going 40" high and have the legs 60" wide for stability (sound right?)....  Aaron's concept looks simple and not too heavy.

thanks for the drop info Paulo!
