phildawson8270 Posted November 3, 2013 Report Share Posted November 3, 2013 As the title says. After next week, I am off work all week so I am going to get the fairing fitted. I need the material to be workable with hammer and vice, but strong enough to support the fairing. I was thinking 3mm aluminium, if not, what thickness should I grab a sheet of?

Superdunc Posted November 3, 2013 Report Share Posted November 3, 2013 3mm NS4/5241 will be fine and easy to work. Link to comment Share on other sites More sharing options...
phildawson8270 Posted November 3, 2013 Author Report Share Posted November 3, 2013 I can only seem to find 3mm thick in 1050 Is this too soft? Link to comment Share on other sites More sharing options...
Superdunc Posted November 3, 2013 Report Share Posted November 3, 2013 Yes 1050 is pure aluminium, and very soft. NS4 should be easy enough to source. Link to comment Share on other sites More sharing options...
phildawson8270 Posted November 3, 2013 Author Report Share Posted November 3, 2013 Google shows NS4 as 5251, was your 5241 a typo? If so, I have found a sheet of 5251 on ebay Link to comment Share on other sites More sharing options...
Superdunc Posted November 3, 2013 Report Share Posted November 3, 2013 Yep typo sorry. Link to comment Share on other sites More sharing options...
phildawson8270 Posted November 3, 2013 Author Report Share Posted November 3, 2013 Awesome, thanks for advice. It will arrive next week! Link to comment Share on other sites More sharing options...
Evilchicken0 Posted November 4, 2013 Report Share Posted November 4, 2013 Why not use a thinner gauge like 1.5mm but a channel or angle section which is gets its strength from its shape. You can get it at Leyland SDM too Link to comment Share on other sites More sharing options...
2moto Posted November 5, 2013 Report Share Posted November 5, 2013 I'd agree, 3 mm is a bit on the thick side. It'll be tough to bend which presumably, you'll need to for fairing brackets. Channels are even harder to bend. 2 mm 6082-T6 is what I use. Anneal it with a blow torch before bending. Plenty of strength, readily available.

phildawson8270 Posted November 5, 2013 Author Report Share Posted November 5, 2013 I have got some of the 3mm 5251 on the way. If I have trouble, then I will try out 2mm 6082. Don't really think it's worth the hassle with channels, far too much effort and work for 4 fairing brackets. Link to comment Share on other sites More sharing options...
phildawson8270 Posted November 6, 2013 Author Report Share Posted November 6, 2013 3mm arrived today, and it is pretty damn stiff, so I have just ordered some 2mm, so have a choice next week when I give it a go. Link to comment Share on other sites More sharing options...
2moto Posted November 6, 2013 Report Share Posted November 6, 2013 5251 is good stuff but really tough to cold form (bend). And, you can't anneal it. 6082 can be annealed pretty easily, but you have to bend it right away. 2 mm can be cold formed even without annealing unless you need tight, sharp bend, in which case it will tear.
