Has anyone ever built there own chassis.i am thinking it can't be that hard.i assume you can buy all the spring holders crossmembers ect.i was going to buy a galvi one but I reckon I can trace the chassis legs shape with cardboard and transphere to steel plate and build it . I love to know if anyone has done it before.

Thanks andy
 
First of all you need to build a jig out of heavy steel and set that up accurately and level, then you can start making your own chassis.
You will of course need all the skills necessary for stress relieving the sections as you build them or else even the jig wont save you from creating a mutant.
For a one off buy a ready made chassis built by someone who knows what they are doing.
If you plan on knocking out 2 or 3 a month then get the jig set up.
 
Thanks but I was a plater I know what am doing with steel. ie made things from steel. The jig is for doing it again and again. Anyone know cause I don't how to get the chassis rails shape into a program called vectors for a profile burner to save me doing it by hand. I recon that could make it for about £500 inc galvi. So I think I will try £500 or £2000
 
Hi

May i ask plse , if u built ur own chassis would it then have to be inspected or vin plated for insurance purposes

Will u have have to work off blueprints and how can u get it all square etc without some form jig

Not a criticism just in intrigued

Many Thks

It's just metal .to square it up cross measure with a tape.a jig is only to make it faster to build don't need to measure. My idea is I'll buy spring holders ECT but make crossmember ECT. I am just wondering how to take the shape of a 500mm section and put that into a computer file so a profile burner can cut it out . It would make the process a lot faster.i the chassis number stamp it yourself.

Just a thought, but a landrover chassis isn't actually that good, it has the inbuilt weakness that mud and dirt will always get trapped inside the box section, and cause rust over time.

If I was going to make a chassis from scratch, I would use a heavier gauge metal, and use an upside down U section for the chassis rails.Then galvanise it.

That was the method employed on the UMM Alter, and the chassis on those last almost for ever.

Many thks, never seen one of those machines apart from on TV , look very impressive

Wonder if a chassis built from tubing could be a better design and stronger ???

Something like this

Still has the inherent weakness of the voids inside being difficult to rustproof, and trapping dirt.

On the UMM, dirt and mud just fell out of the upside down section when dry.

Ah i see, will have a search ref the UMM

Thks , just finding it interesting

They were an excellent vehicle. Many people think they are where landrover should have gone.
Simple, leaf springs, galv U section chassis, cutaway wings like a lightweight for better visibility. And they used a proven existing diesel engine, the PSA 2.5.

Many Thks, remember them now , PSA , is that the French engines plse

Still searching for the chassis design

As used in Peugeot cars, a very well thought of engine, and with good parts availability.

UMM haven't been around for a while, not sure if the chassis plans will have made it on to the net.

Thks, Just released like a doughnut the engine in mine is a PSA design then JLR done some further mods to it, ie deeper sump etc etc

Never seen the stretch version, lol , would certainally be an alternative if u didn’t want a landy

Trying to think if it was the Aussies that really liked them

Haven’t found anything yet

If I ever needed a working vehicle again, I would probably look at getting a UMM, there is an active owners club who help with parts, and still quite a few on the road.

Fortunately, the only working vehicle I need these days is my boat.

I hadn't. Not seen a UMM in the flesh for donkeys years. One of the blokes I used to work with had one, but that was back in the 80s.
