Hi everyone thought i would do a little article on make your own rotisserie, i made mine about 2 years ago and is probably the best thing you can make for working on your car, you can make one for around quarter of the price of a bought one and the main thing is that you can make it to suit the application that you want it for.
The whole frame is made from 40x40x5 RHS mild steel.
Im using my rotisserie for a MK1 ford escort i have mounted the front cradle on where the quarter bumper brackets mount with the two bolts that go through the chassis rail so all up the front cradle has 4xM10 8.8 high tensile bolts , the rear cradle is mounted on the leaf spring mount where i have used a M16 bolt to hold it in which is 8.8 high tensile.
The pivot point in the middle of the frame is a m20x130 8.8 high tensile they are that long so that when you rotate the car on the bolt it isnt turning on the thread it is turning on the plain shank of the bolt.
Here is a drawing of the end frame really easy to make.
This is the front cradle which if using for a different car you will need to make them to suit, you can see the two bolts holding the frame on at the front
Here is the back cradle it has two bolts through the chassis, you can also see the m20 bolts where the pivot is and the one at the bottom is the locking bolt.
Hope this info helps someone out and make there project that much easier, best of luck.
