Guys, what is the best thickness to use for making a trans tunnel? This one shouldn't cause much controversy. Thanks!
I use 20 gauge for smaller parts, for a whole floorpan 18 gauge won't need as much beading for strength. Now a related question; what are people paying for sheet metal? If I bring cash to the steel yard and don't need a receipt, I get a 4' X 10' sheet of 20 gauge hot rolled for $40. I think that is reasonable.
I used 18ga. on my trans tunnel and if I'd had 20 I would have used it. 4x8 sheet of 18ga. was $75 last time I bought one.
20 for the tunnel, easier to form and the curved shape gives it plenty of strength. 18 for the flat floor sections. Never saw hot rolled thinner than 16 ga; but,then again, never thought hot rolled was useful for automotive sheet metal. Posted using the Full Custom H.A.M.B. App!
I use 18 ga for all floors and firewalls, built a heavy duty bead roller so I have no problem with that part. .If you dont have access to a slip roll, it might be eaiser to form 20 ga for a tunnel. SPEEDY
I picked up a sheet of 4 x 8 18 gauge to make Brenda's sign frame for her Flower Shop last week and it was 64 bucks. HRP
