Forming aluminium U channel

[W.olly]

Hi all, i have a little project to finish off and i really want to add a trim around the edge.

It is boat hatch as here

The perpsex/acrylic or what ever it is i forgot now is 8mm thick and i am wanting to put a 12x12x2 mm channel around the edge.

Before i go faffing about trying to make the jig using the spare 8mm sheet i have i was wondering if it will work without distorting the channel to much if at all.

The radius is near 100mm and this is an idea for a jig to roll the channel around the jig made from the spare 8mm piece i have so then i can do it in one shot forts screwed down into the perspex at the start to hold it tight in place with 4mm SS screws.


A Bearing of 37 OD x12 x12 to roll it around.
3mm thick SS to hold the channel edge down for crumpling.
Pivoted on the 8mm bush inside a 12x2 Oilite bush just to protect the perspex a bit.

This lever will be moved onto each corner.

Once done removed and fitted to the screen above, the hinged side will be cut to get around the hinges so that will make it a little easier to fit the frame around i hope.

Is it worth trying to do ?


Cheers

Anybody done anything similar.

only via the copper pipe former not tried it yet with steel

however if principle is the same then it should be easy enough to create

i have this type of bender

outside rolling maybe able to do but inside im not too sure on it should be able to do it though

I think your plans will work, take care though as this bloke almost come a cropper.

Ooo i like that nit of kit, keep my eyes open for when i have a spare few quid for one

Thats a lot bigger than what i will be using so my plan is good to go

Is it or does it look to have crimpled a little on the top radius on the frame ?

It did look a little flimsy made from wood. Still done the job for him.


Thanks guys

nearest ones to it is the wolf or clarke compact bender but i have the harbour freight one

its got plenty of uses to it including rolling things with it

Not sure if the annealing in the video was very effective.
Hope this helps.
