The other down side of these is you can't turn the body up-side-down, but I'm yet to find a time when I need to do this, it also needs 2 people to flip the shell. They aren't heavy at all, but just too big to handle. Both the operations according to the requirement may be similar or different. Once machining at both the stations is over, the fixture is indexed through 180 degrees so that the first component is shifted to the second station for the second operation and the finished component to the first station. When you see some of the other cars they have had on these, the weight of the Minor is not really an issue. So much so that as I am a little tight for room, and I am feeling too old for grovelling on the floor as much as I used to, I was going to remove the front uprights and get it on the jig and roll it over and then take the torsion bars and rear axle off while it is on the jig. Then of course it would need moving on the jig to rebalance it. It enables the production of identical parts which are interchangeable. This facilitates the assembly operation. The finished component is then uploaded here, replaced by a fresh component and the first operation performed on it. The cycle goes on repeating, which enables mass production of components at a fairly high speed. Welding Fixtures

It enables a semi-skilled operator to perform the operations as the setting operation of the tool and the work is mechanised. This saves labour costs. Very sensible indeed. I talked to the guy yesterday and he explained that he would be supplying both the saloon and the traveller mounting options. I cant imagine how they differ at the moment as I don't have a saloon to compare. Perhaps its just the rear hole centres on the bumper mounts. However, every type of object cannot be machined on a capstan or turret lathe and may involve the use of drilling, milling, planning and grinding machines, etc. If such objects are to be produced in identical shapes and sizes on a mass scale, suitable devices have to be used for holding and locating purposes so that the repetition work can be done. These devices are the jigs and fixtures. What is Jig? All the Roll and Restore jigs have adjustable balance and clamp system meaning you will be able to adjust the shells Centre of gravity to make it easy to roll normally one hand operation. With this huge range of adjustment making them very universal it has made them very popular with both professional and home restorers.Brilliant idea, I think ill follow suit on this one, I'm now decided on the self loader/balancer anyway ill have a look today after whipping the engine out, if it looks remotely like the job I expect it to be then ill leave it until I can do it standing up with a cup of tea in one hand.

Finally, the elastic and velcro bands ensure everything stays in place!

The speed, feed and depth of cut for machining can be increased due to high clamping rigidity of jigs and fixtures.Welding another bar along the existing stump and then replacing the bumper iron as one of the last jobs (because I had not decided if I wanted a front bumper or not) Against this, a capstan and turret lathe can be easily adapted for repetition work on account of the multi-cooling arrangement and use of transverse stop this increases the rate of production. One thing I did notice with the jig, you need to bolt the disc with the holes on it for the locating pin yourself, that needs to be done when the car is at its correct height if you want it to sit straight. We got the car off the ground and it looked right so we bolted it up (you have to drill two holes yourself because they don't know where they need to be) and the car was level. We then found it was too high and we could not do a full rotation in his garage so it was lowered by extending the cross bar and splaying the legs. This then moves the location of the pin relative to the disc so instead of horizontal his now sits more like twenty to two. The function of these fixtures is to hold different components together in their proper relative position at the time of assembling them. For example, two or more steel plates can be held together in relative positions and riveted. Roll over jigs are great for body restoration and race preparation making welding in floors, sills and enclosed sections a lot less daunting especially for those newer to restoration been able to have the car body at a angle that not only is easier to work on but also allows you actually see what your doing there is also the safely aspect of not having to weld or angle grind underneath with all the hot sparks falling on you and burning your skin.
