Paddy_SP Posted May 26, 2017 Share Posted May 26, 2017 I've been refurbing my B & C posts - which were like most of those found on nearly 25 year-old Defenders, with the lower half resembling papier maché in many places... Anyway - after welding in a length of 40mm box along the horizontal section, I found that it'd bowed like a banana. Now this is obviously something you have to expect with long weld runs, so I made up a damned great jig to pull it straight again. When I'd got the bend down to a couple of millimetres, it occurred to me to see how bent the other side was - which I hadn't touched at that stage. Blow me - it was also like a banana, albeit not quite so bad... The problem therefore, is how straight should I make it? I haven't got enough of the rest of the bodywork in place to offer it up, and I'd hate to go to a lot of effort only to find that LR - in their wisdom, had designed the chassis to allow for distortion during production!

ballcock Posted May 26, 2017 Share Posted May 26, 2017 I believe they should be straight, I hope so as I made sure mine were when I repaired them. Quote Link to comment Share on other sites More sharing options...
western Posted May 26, 2017 Share Posted May 26, 2017 bottom sill channel should be straight, the B post should be vertical & C post is angled from sill then goes vertical to match rear side panel. Quote Link to comment Share on other sites More sharing options...
Paddy_SP Posted May 26, 2017 Author Share Posted May 26, 2017 Thanks, Gentlemen - it was the bottom sill channel (well, now it's box) that I was concerned about, but wasn't at all sure what the LR production 'tolerances' were! Quote Link to comment Share on other sites More sharing options...

If you are making this in box section how do you plan to bolt the bottom cill trim and body mounts in place? Quote Link to comment Share on other sites More sharing options...
western Posted May 27, 2017 Share Posted May 27, 2017 we used 50mm x 30mm x rectangular box 3mm wall thickness on my 110 just drilled & tapped the box for the floor plates & sill panels. Quote Link to comment Share on other sites More sharing options...
Paddy_SP Posted May 27, 2017 Author Share Posted May 27, 2017 Yes, I've installed threaded bosses in some places, and drilled various mounting holes as per the original locations. Quote Link to comment Share on other sites More sharing options...
