I decided to purchase a Jig and went for the Huddersfield spare one, simply because it was powder coated which meant that I wouldn't need to spend extra on paint. The Jig looks like a clone of the rolloverjigs.com one however it is a superb piece of kit. The only drawback was it wasn't supplied with instructions and how to set it up so it took me a wee while to get right plus it was supplied with a gate latch to use as the lock. The latch was too big for the frame and in my opinion wasn't safe and looked very flimsy. I emailed H.S about it but they never got back to me.......
Here is the Jig assembled
I have since added castor wheels and braced the frame to stop the feet from flipping over. I don't have photos of that but I do have a video
