Crossmember Fabrication?
I know that I always ask questions about fabrication and yall are probably thinking that Ill never do any of it, but Im just waiting on the summer and some more CO2/Ar welding gas (been doing too much wheeling to have time to go get some).
Anyways, do you think that if i made a new crossmember it would be strong enough? How thick (wall) of pipe would I have to use? Id use 1-3/4" pipe, but of what wall thickness?
My current crossmember is mounted to the passenger side of the axle to the cener of the truck, and is about 1-1/2 ft long, and obviously will have to be relocated to the driver's side frame. Ill make that mount too, out of 1/4" steel.
So, basically Im asking if yall think I can fabricate a crossmember strong enough (aside from welding skills) for an F-350 and it not break (or at least anytime soon, like within 2 years)?

what's the crossmember for? tranny mount? just a crossmember? track-bar? I would say use some 3/8" cold rolled steel plate or angle iron. and then use E7018 so it will be strong enough for just about any application.

Here is a crossmember and skid plate that a buddy made for his jeep:
Those bushings he got from www.mountainoffroad.com ...they'll help dampen any vibes.

Yeah, track bar too. For some reason ford called it a locater arm, so did superlift, so thats what Ive always called it...
By pipe I meant tube, not pipe... bad habit of mine...

I would use 1020 DOM 1.5" OD, wall thickness of .95", and 1.4" ID. that would be very strong and maybe even use heim joints on the ends to allow for a lil bit of bind, but i dunno if that would hurt the ride in terms of DW. Use 6010 root pass on about 115 amps and then use E7018AC as multi passes for added strength.
