half round of 3mm steel

[gaz1]

ive wanted a size of pipe 3mm thick by 660mm and I had some 3mm sheet handy so decided id give it a go with rolling it into a round shape

heres the results via a wagon ratchet and finally a big vise to close the shape smaller still

heres some pics of rolling it in the end I used a vise to bend the edges so they didnt cut my straps by standing and pushing on it a gas bottle to roll it smaller.

then a 8" lamp post to get even smaller or as much as a circle as possible and got it too about 10 1/2" from a flat sheet of steel 26" high x 18"





in end i ended up using a large vise to get it smaller on the width from 10 1/2" to 7 1/2"



ive had fun making it like that

ive also decided i want a bender/ roller machine to do more of these

this is the shape i was roughly wanted to get after straightening it out its near enough to what im wanting



a half round into some straight bits but i can do this with a half round pipe and a u shape to make the front part and a little bit of welding to join up with both ways used

as this item needs to be 3mm thick

May i ask what its for?
Your also going to need some really big heavy duty rolls to be doing 3mm sheet

the metal is for the back of a rocket stove

im not going any bigger than a metre and it has to be stored outside so anything has to be removed and put away otherwise it will get pinched even if its in the garden the only thing i can leave outside is the leg posts the jack and beams have to be put away
