A bit of unexpected success today.

Angle aluminum is very useful in building an obs, wheels can run on it, the angle part can be used to guide with more wheels say on a ROR. Its thin and strong.

But its straight, no use on a dome. I need to make a curved rolling slot cover with extra wheels also for guiding and some way to stop it falling off. Im thinking more tedious chunky circular bits in plywood from a large sheet.

BUT NO, you can bend angle aluminum into a circle without some fancy bending machine, I kid you not!. (I can hear mechanical experts saying duh, im not a mechanical expert).

Upon googling, turns out you can turn angle aluminum into butter and bend anywhich way by annealing it!.

Looses some strength but I dont care. to anneal, you heat up to a specific temp and let it cool naturally. How to know the temp?. its nuts, do some squiggly lines with a sharpy (a sort of texta, bunnings have them) and when you heat the al with a blow torch you know the temp is right when the sharpy lines disappear.

So off to bunnings, get a bunch of angle al, a blow torch, sharpys and start learning. The test went very very well!.
