Snowy Posted May 31, 2015 Author Share Posted May 31, 2015 So it is ok to do with no other bracing? My roll over jig is connected to the bumper mounts front and rear? Thanks Quote Link to comment Share on other sites More sharing options...
mantadoc Posted May 31, 2015 Share Posted May 31, 2015 To be honest it depends on how solid, and rigid, the remaining bits are. Especially the inner wing joints to the bulkhead and foot wells. If they are at all soggy, or if in doubt it may well be worth bracing. Quote Link to comment Share on other sites More sharing options...
Snowy Posted May 31, 2015 Author Share Posted May 31, 2015 The car is solid enough. It just doesn't seem like a good idea. But if it works it works. I did the drivers side chassis rail from underneath only cutting out sections at a time. But if you can cut the whole lot out without any issues then I will do the passenger side like that.

eldoradoCoupe Posted May 31, 2015 Share Posted May 31, 2015 I put a brace on mine which doubled as a dolly. Aldo supported the inner wings against the floor with 2 vertical props. I tried to do them bit by bit but ended up chopping the whole lot one side at a time. I used a bit of threaded bar like in your pics to keep an eye on the position of the chassis rail holes. The passenger side didn't move at all but the driver side had moved by about 1mm by the time it was done, see the 3rd pic, (the bar started out bang in the middle). Anyway, not sure if it needed all that or not, maybe would only have a moved 1mm without it, but I felt a lot more comfortable about it! 1 Quote Link to comment Share on other sites More sharing options...
Kevin Abbott Posted May 31, 2015 Share Posted May 31, 2015 (edited) Most of the strength is in the inner wings and ' A' posts. I did those first and the sills on the ground so it was very strong. Then I did one at a time and didn't put any stress on the shell when welding it Edited May 31, 2015 by Kevin Abbott Quote Link to comment Share on other sites More sharing options...
mantasrme Posted June 2, 2015 Share Posted June 2, 2015 I always make sure the inner wing tops and upper A panels are solid then there is enough strength to transfer the load from the front to the main structure to do a rail at a time easily. You can even do the rail and sill the same side (assuming it's mostly just the outer sill) If in doubt about the shell bracing never hurts, as long as you don't find you put it right where you want to access to weld later. 1 Quote Link to comment Share on other sites More sharing options...
Retro Power Posted June 2, 2015 Share Posted June 2, 2015 Ditto all the above, it's strong enough if the a panels and inner wings etc are good 1 Quote Link to comment Share on other sites More sharing options...
Snowy Posted June 3, 2015 Author Share Posted June 3, 2015 Thanks guys. I always thought the strength came from the rails. Thanks Quote Link to comment Share on other sites More sharing options...
