Rotating Chassis Jig
 

I built a jig for holding and rotating my chassis while working on it.

You will not believe how useful this thing was when doing everything from painting to welding to whatever.

I have made a silly video of it below:

Would highly recommend this if your at this stage and have an afternoon spare.

Nice work but....

Great idea, very useful, but forget the car rotisserie, I want one of your double decker bicycles!:D

Grand idea Jimbob and a cool video......;)

Keep it up.....Andrew

"The Rotating Chassis Master" I love it :D

if possible could you give me some dimensions.

cheers

very good you seem to have added quite alot of extra bracing to your chassis is there a particular reason for this?
Ray:)

I have seen chassis jigs made in a similar way, would make it a lot easier to weld up as non of that clambering malarky only to lean on a joint you just welded.....how many times and how many pairs of ovvies I went thru I dunno:(

I used to weld up 5mtr long stillages on a rotating jig, which after 45 mins of welding 6mm angle and 50x50x4 box would clamp it self around the jig. They used to make one hell of a bang as it hit the floor from 3ft up.
I would say if your planning on using one to finish weld a chassis I would make a removable flat base to clamp it to. Theres alot of unsupported weight in the middle of the chassis and don't forget that welds pull too no matter how careful you are.

I wouldn't clamp the chassis to weld it, it will move...:rolleyes:

And you think lifting a half welded chassis from the build table in to a rotating jig unsupported in the middle hanging by it's own weight will keep it straight?

I forgot, of course you are a clever sod and can weld every single joint while the chassis is sat flat on a table......:rolleyes:

Ok I give up.

The jig wasn't used until virtually all of my chassis was welded, the jig only became useful when I was doing things like painting prep, actual painting especially, preparation of aluminium panels, and a few small welded brackets and things. This is not a totally standard build so there has been a bit of fiddling about with things over time.

I wouldn't have considered hanging up a half finished chassis - such as only tack welded or something. The idea of using a table is so you keep your car straight, hanging it up in a jig like this put BIG loads on it.

I think that is a cracking rotating chassis jig Jimbob :)

Ideal for what you have used it for.

That youtube vid really made me smile, well done for such an entertaining video.
Shown it to all of the family & has entertained everyone :cool:

I don't think anyone meant to imply that you had welded your chassis up on that. ;) :)

just a thought and ill probably get shouted at but if you welded it with it sagging but only welded the top welds it probably wouldnt pull as the weight would keep it from moving. also once all the braces are in its a pretty strong structure.
awaiting abuse with baited breath lol

:D :D

I guess it wouldn't be too difficult to fabricate an open lattice bed to clamp the chassis to & then fix that to the rotating A frames ;)

Personaly, I have seen & used a fair few fully rotating fabrication jigs.

As they say, where's there a will, there's a way :)

I have used the Image Sports Cars Jig when I was asked to rework part of the chassis, the jig was made from damn heavy RHS and had cheaky wee slots where certain joints were to allow as much of the chassis to be welded prior to it being taken off. The jig rotated but not exactly a one man job as once the locating peg was removed all hell let loose and it swung upside down.....:D

I never meant my comments to be abusive..:o ..I'm a sarcastic sod and those that have met me might have noticed.

Never even thought about them in that way Mark :)

Your darn right about the real deal jigs being heavy duty & I guess that sort of thing is out of the question for a One off job.

If I were to set up a dedicated chassis assembly business I would invest the time & money in the correct jigwork.

There you go Mark ...Filling my head with silly ideas :D :o
