Hi All
I have just acquired a 1929 chassis in bits. It will be the basis of a reproduction "Cox" sports tourer. There is one around already (RX 2740) but I hope there will be room for another one! The chassis is all there but there are a couple of questions I have.
Firstly my 1930 RK has chassis cross members with open ends and support for the body at its extreme ends. The acquired chassis cross members are shorter and have webs that have been folded in. Both types appear to be "factory". Purves shows the open ends on a 1932 chassis and the folded web type on several diagrams prior to 1928. I can't find any reference to when the change actually happened. Did this change occur with the wider AD tourer in late 1929?
Secondly the offside chassis rail is bent (vertically but not laterally) and cracked across the rear engine mount hole. I've read Parazine's thread on restoring a top hat but his chassis was bent laterally and I think he has used new straight rails. My cross members seem pretty straight too. I'd rather keep the original rail so....
Options for repair... Cold bending back to straight then welding up the crack?... Heating to cherry red straightening then welding a strengthening plate under the top flange?
Advice very welcome
Cheers
Howard
