Happy New Year to all.
I've wrestled the rolling chassis into the garage and have been removing the front axle and suspension.
By g, them springs is heavy but nothing like the front axle lol ¯\(°_o)/¯
But hey the Chassis is way more manigable to handle without the axle and springs ◉‿◉
Restoration of a Series 3 chassis doesn't seem to happen !
Repair, yes lots are repaired with a new section cut and welded in, outriggers replaced even entire sections disgarded and replaced.
But all the replacement leg parts are 4bits of steel welded at the edge, and the origonal was constructed of two U shaped halves welded together. Which rather reminds me of the look of the seam which runs down a stocking leg.
All the new/replacement chassis are made from four bits welded at the corner, usually of 3mm steel and often galv too.
But but the origonals' legs are of two halves welded and of 2mm steel, all the crosmembers and some other stuff being of 3mm steel.
For most folk I don't think these subtle differences matter.
Ok so having a 3mm replacement section on a 2mm chassis will not flex in the same way, transferring extra stress on to the original parts, but a Landy's chassis is well over any required strength, so this doesn't really matter that much.
But anybody that knows their stuff can immediately see the differance at a glance.
In the original 2mm chassis, there are unseen internal structures in key places. They can reveal themselves when you try to cut a bad bit out to replace.
I have seen just one professional chassis restorer who completely OTT, had an entire Jig set up to every bolt hole in the chassis. So it must have cost tens of thousands, well beyond reality for all but the ludicrously wealthy.
Having said that I have built a car on a Jig which used several hundred pieces specific to that car, in a Vibba approved body repair shop. It was decades ago, but great experiance.
Anyway what was interesting was that this guy was restoring a chassis which used the same two U sections welded together as my Landy.
What interested me was that for the section he was restoring, he cut half of the U section along the weld and then through at each end.
Consiqently he pulled a section away from the side, leaving the other original half in place.
This ment he could remake the corroded part to weld back using the removed section as a pattern, but also that he had awesome access to the inside of the chassis all round the affected area, so this could be cleaned and made good too.
He was careful to well support the rest of the chassis as to place no stress on the section being worked on.
It got me to thinking; maybe the original chassis can be repaired and in a way that would be completely undetectable even to the most experienced eye.
Would this not be a concourse restoration ??
