Anyone got a guide on making one for a car? My Sierra will no doubt need a new chassis leg the full length at the back in the future, and was wondering if anyone was a past tool maker for car companies? Any advice? My plan was to make something that lined a chassis leg from motomobil in relation so that the rear beam sits true after both chassis legs are replaced, and so it doesnt crab... I will try and get some pics of it on other Sierras if I can so people can see what I mean. Also, will I have to do it when the car is on axle stands, and a dolly under the rear floor, or can I put it on the jig and do it while it is turned over? Or will this kink the chassis because a major structural piece is missing.


And the reason I am asking this question is just for future use, as I plan to restore this car again at some point, but no doubt it will need new rear chassis legs! I have repaired them for now...

Thanks in advance for any advice.

The chassis legs in question.

you will be pushed to find chassie legs mate will have make them or just get a root free shell ,or just cut sections out that are rooten and replace

cut one side out at a time and when you weld back in bolt the beam in an shock will line it up or make a simple jig if you can weld

You can get the sections from motomobil for 80 quid. And is that all that would be needed?

you rang them to see? carnt see why you need a jig just drill spot welds out un pick it and weld in .a side at a time ,if you can use a tap measure its easy

I should be fine with the welding when I come to do it, I'm doing a metal welding and fabrication apprenticeship later this year. And can I ask what a tap measure is?

clever twat lol stupid iphone auto correct tape measure ,id price all the panels up as it looks like it needs inner outa arches and sills from picture ,as you can pick shells up for next to nowt these days

SMILER258

I have repaired all those places, replacing the rear quarter atm. It has massive sentimental value so wont be reshelling, as otherwise it'd have been scrapped by now lol. And ah! Tape measure, I thought tap measure was a special tool of the trade

in that case just take ur time you can make a jig that bolts in diff mounts then across to both sides and bolts were the beam bolts and rite lots of measurements down drawing an that ,failing that you should be able down load the spec sheet for jig work on the car if its still available

SMILER258

Where would I be able to find this? And cheers for the help Dingla, absolute god when it comes to advice!

no problem iv repaired a few ,I use to have it all on discs as I used to jig cars straight ect ,im sure there would be some were on wed to down load it ,like say make a jig that bolts in the holes for diff and beam ,make sure holes are 100%same size as bolts and then make it so it sits on to sills or something like that,a part that wount alter when you cut chassie out ,that way the jig will be at rite height ,so will chassie leg ,if you get my poor English lol

So I should have a bar that goes across the sill, that joins to the allignment frame, so it is a clear indicator of wether it is level or not? And the holes that would let the bolts go into the chassis leg must have a very small tollerance so it cant move? just to clear up lol. And I will have a look on the net for the jig measurements, or will email fords design or history department for them. See if they will let me have em

yes if making a jig bolt holes need be 100% but could tack weld in and try beam in.with a jig I made I used angle iron over sill and the welded box across then to jig just another reference point to keep it straight

SMILER258

Brill! Everything I needed to know cleared up! You're a star lol I would add rep, but it seems I've given you too much already

It would be a one off, so I couldn't justify the price for the use I would get out of it.
