Arjan Posted May 28, 2020 Share Posted May 28, 2020 As English is not my native language, this is not easy to describe but I'll do my best.... I'm building an elevating roof on the 110 - basically a section of 180 x 110 cm. that is lifted some 70 cm. to give standing height. Almost everything part & bits wise is here but one thing : the corners. 8 of them. The fabric is attached to 20x20 mm. aluminum angle profile but I need to make rounded corners - not 90 degree sharp ones. I found a few places who 'll gladly make them for me but they require a 2nd mortgage for the privilege.. As we have many people here from many backgrounds and skills, I hope somebody here has an idea. 3D printing ? Open for suggestions ! Many thanks.

FridgeFreezer Posted May 28, 2020 Share Posted May 28, 2020 Cut and weld? Quote Link to comment Share on other sites More sharing options...
landroversforever Posted May 28, 2020 Share Posted May 28, 2020 Any little body shops nearby that Would have a shrinker? Shrinking on of the sides of the angle would bend it. Quote Link to comment Share on other sites More sharing options...
Arjan Posted May 28, 2020 Author Share Posted May 28, 2020 Out here in rural France, those shops are simply not there. And fabrication places that are there don't even want to talk to you. To give you an idea : I have a galvanizing plant 30 miles away and they do not want to touch a chassis to do, so I'll be dragging it 1600 miles over 4 Borders to get it done..... Deep, deep sigh...

Arjan Posted May 28, 2020 Author Share Posted May 28, 2020 cutting & welding is an option..... However, I can't weld aluminum Quote Link to comment Share on other sites More sharing options...
landroversforever Posted May 28, 2020 Share Posted May 28, 2020 That’s a pain. Is it something you could sketch and get made over here? Quote Link to comment Share on other sites More sharing options...
mmgemini Posted May 28, 2020 Share Posted May 28, 2020 How about you make and bend both the inner and outer pieces then join them with a "U" tube pop rivited into place.Alaralite is good uesed on alluminiun Quote Link to comment Share on other sites More sharing options...
Blanco Posted May 28, 2020 Share Posted May 28, 2020 Shackleton on here experimented with the low temp soldering on aluminium, didn't seem too difficult, might be worth having a play? make the pieces individually out of 20mm flat bar and solder them up after??

elbekko Posted May 28, 2020 Share Posted May 28, 2020 Or rivet stuff together. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 28, 2020 Share Posted May 28, 2020 We need a bit more information what thickness aluminium angle are you looking at shrinking machines have a limited capacity unless you have access to industrial equipment what diameter curvature and length of material past curve regards Stephen Quote Link to comment Share on other sites More sharing options...
Arjan Posted May 28, 2020 Author Share Posted May 28, 2020 I'll try to do better.. May have found a solution using a 80 mm "nylon pole"I have in the workshop.. Let me finish some trains etc. and I'll get back.. Quote Link to comment Share on other sites More sharing options...
secondjeremy Posted May 28, 2020 Share Posted May 28, 2020 If plastic will do you you can buy blocks of the stuff from e-bay. You may then be able to shape it with router. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 28, 2020 Share Posted May 28, 2020 (edited) Hi Arjan been thinking about this you could form your own curved angle sections out of flat sheet with a few basic tools ie a hammer some clamps and a couple of pieces of hardwood I have done this before you need to create the profile you want out of hardwood and then clamp your shaped piece of flat aluminium in between both pieces of wood with the section of aluminium you want to form up outside of the clamped area then just gently tap it up and form it around the hardwood the aluminium being very malleable will shrink and stretch as required with the hammer I could give you a bit of a picture tutorial at the weekend if you want regards Stephen Edited May 28, 2020 by Stellaghost Addition Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted May 30, 2020 Share Posted May 30, 2020 So had a wee shot at this below are the results for about half an hour's work done quite roughly results would be mint with a bit more care so raw ingredients first some 3mm aluminium cut to shape and a couple of blocks of hardwood all formed quickly with a jig saw Then clamped in vice and started gradually knocking over with hammer Semi finished result you can see where the aluminium has stretched upwards picture in next post will show end result regards Stephen Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 30, 2020 Share Posted May 30, 2020 (edited) Me again picture shows final result with excess trimmed off so quite doable with basic tools regards Stephen Edited May 30, 2020 by Stellaghost 2 Quote Link to comment Share on other sites More sharing options...

Arjan Posted May 30, 2020 Author Share Posted May 30, 2020 So, if I understand this correctly, this started with a flat pieve of aluminium you basically gently bashed into the bent and then grinded off the excess ? Sounds simple - and doable for 8 corners..... Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted May 30, 2020 Share Posted May 30, 2020 (edited) You've got it formers to be hard work or metal regards Stephen Edited May 30, 2020 by Stellaghost Quote Link to comment Share on other sites More sharing options...
