what should a guy use to build a tunnel extension
08 Phazer one piece? cover exhaust hole and add 12" to tunnel for extension
3003, 5052, 6061,????
.050" .063" ?????
stock tunnel seems to measure @ .060?
 
Same thickness and probably 6061. You might get away with .o50 but why bother. Check the pricesess and there is probably not much difference.
 
.063" or thicker 5052

Any other aluminum will be brittle, and not bend well.
 
thanks guys
Rick I thought u guys only posted at night lol
love reading yours & Calebs build
 
I'd use 5052 .063 like Rick mentioned. CR uses 6061 which is stonger, but more $$ than 5052 and harder to work with. 2024 is even stronger and bends good with a slightly larger radius but it's almost triple the cost. If you can, bend with the direction of the grain(so you're bends end up perpendicular to the grain)it will be stronger and less prone to cracking.

As far as I'm aware, every aftermarket tunnel is 5052 except for CR Racing.

3003 H-18(full hardened) has an ultimate strength of 29,000 psi, Brinell load of 55, and shear strength of 16,000 psi
5052 H-18(full hardened) has an ultimate strength of 41,000 psi, Brinell load of 85, and shear strength of 24,000 psi
6061-T6 has an ultimate load of 45,000 psi, Brinell load of 95, and shear strength of 30,000 psi
2024-T3 has an ultimate load of 62,000 psi, Brinell load of 120, and shear strength of 41,000 psi
7075-T6 has an ultimate load of 76,000 psi, Brinell load of 150, and shear strength of 46,000 psi

Those were numbers I grabbed quick out of an old handbook, the numbers might have changed since 1985 haha. If any of them are incorrect feel free to correct me and I'll edit my post.
 
Don't forget 2014-T6 and 6082-T6 which are very common around here. I don't know any numbers in standard units, but they are normally referred to as the second and third strongest after 7075-T6. The drawbacks are that they - like 7075-T6 - do not bend very well. They are also - like 7075-T6 - much more sensitive to corrosion, especially compared to 5052.
 
Alatalo : did you work with aluminum. I need some material for my project. Can i buy some from you ?
Sorry for off topic.
 
thought I read you were done posting till your sled was rideable ha ha
