Ahhh, how times have changed, we used to cut up old biscuit tins and soft solder shapes similar for things like fuel tanks in control line models and model boats. Those skills are getting forgotten and the new taken as the only way to do things. I am not one to turn my nose up at 3D printing, but do mourn the passing of old hand skills.

Speaking of 3D printing.... I hadn't really paid it much attention until I saw your thread Joules on your solar shield.... and that led me to this thread... and some pondering and googling led me to here:
https://markforged.com/mark-one/
Has anyone used one of these?
One of the claims is the carbon fibre re-inforced plastic is as strong as 6061 Aluminium (stronger, in fact); does that seem reasonable?
I'm sure I could print some race car bits if it's as good as aluminium... things like engine mounts for example.

It certainly looks very impressive, but they all do on the vendors web sites :med:
Suffers from the small build volume issues that is very common with 3D printers - very few seem to produce large models

LOL, I wouldn't trust an engine mount that has been printed on one of our machines. The carbon stuff sold for printing is (very fine) chopped strand carbon in PLA. I was looking at it for quadcopter use till I realised on a sunny day that PLA is going to get over 50c and start softening. Not the ideal situation for a rigid airframe, think the old soft mint commercials. Could paint it white to reflect the heat though.
The other current big issue with carbon loaded PLA is how abrasive it is. You will destroy a brass nozzle in just a few hours. New stainless steel nozzles have been released that work much better, but I spotted the ultimate nozzle recently. It has a sapphire tip that should last a lifetime.
What is great, make your patterns in normal PLA, then vac bag your pre preg carbon over them unless it also needs cooking. We have done this with glass fibre tissue.
Ade, just looked at that printer and the glaring problem is that it literally lays a single filament along the print... Errrrrr, the filament isn't cross linked to the one below so no extra benefit in sheer. Alot of pennies for a concept I would step widely by.

Ade, this might be more of use in your area of interest.

You don't have to wind just tubes and cylinders with it.
