I've heard of the sand filled tube bending and not tried it - it looks like it works beautifully. I'm binge watching to catch up and looking forwards to the next episodes. Thanks
I guess I never understood the Superleggera building system. I thought the tube frame was there to support the body shell otherwise what's the point? Wouldn't it be better to make the body panels out of a thicker material that would hold it's form better and make bracing and brackets to mount those panels?
It does appear to have a quite bit of extra unnecessary tubing to carry. Most of the old racers would have had a lot less tubing on the outer frame and less weight. I've kept a bit of extra tubing behind the bodywork so if there is a small accident or someone leans on the car in the centre of a panel it doesn't cause a giant dent, only a small one. I think you're correct, that some well placed bracing and brackets built in to the bodywork could probably be just as strong and lighter as the Superleggera. I'm not sure how old Lotus' attach the frame to chassis but imagine it is lighter.
Much enjoyed as ever. Amazing precision on those bends and great to see it done "old school". The bolts as end plugs I'd not seen before. Will there be some sort of padding to take up the gap between the "not touching" tubes and the body skin?
The metal frame will be painted and I've been told to wrap electrical tape around the steel tube where it's close to the aluminium to prevent corrosion. Ideally the frame should be just under the aluminium but undoubtedly there will be a few tubes touching. Glad you liked it!
@@GasoliniASMR To be authentic it should be something to hold water :) Was interested if the tube needed to be close enough to provide support if someone was to lean on it perhaps, but not touch and fret in normal running. If its to never touch it could be a finger width away, and save a lot of bother. Its a level of detail I've never thought about. I expect in period some did, some not, and some lasted more than a single Mille Miglia, and some not.
@@thedoingnotthedone yes, I think I could chop out a lot of the tubes in the centre of the frame to save weight, but I am keeping them in case someone leans on the panels or for small dings that could turn into giant dents. I'm sure there'll be a few tubes touching in places but as you say they were never designed as concours cars

Thanks Pierre. Glad you are enjoying them!
Great work - so much information without a single word! Nicely done.
Thanks! Much appreciated
It's looking good!
cheers Ben

congratulation. beautiful job.
Thanks!
Bravo
Very interesting. Could the tube framework be built first and used also as a wire form buck?
Yes, I believe that would be possible and would save time building the wooden buck. I hope to make a wire form buck for another project in the future.

Possibly some foam cladding type tubes would be an idea to fill the gap. Thanks for the thought!

What wall thickness is the 5/8 tubing
It was 16swg or 1.6mm
