OK, please check me on this. Using bd^3 - h^3 (b-t), I find that an I-beam 6"wide, 4"tall, with .75" flanges and a 1.0" web gives me 25.489 in^4. If my math is correct, this would work perfectly well. At each end of the I-Beam, I'd weld a 8 x 6 x .5 plate to interface (welded) with the...

THANKS AGAIN! Being ingorant of the properties here, I passed over the shorter I beam idea assuming that the tubing would provide more efficient support. Such an I-beam would also be much easier to fabricate with less potential for weld failures. I'll post here in the next couple days after I...

Ah...a man with the math! Thank you, thank you thank you! To answer your last question first, if the trailer in not square behind the truck (usually the case), the sides of the truck box become the point of interference. OK, given the areas of concern per your response, I've rethought this and...

Thanks for the response, Mech. The reason for the additional clearance is to facilitate the back road use of the trailer where we often experience the gooseneck as the high point between a truck moving downhill while the trailer is still moving uphill. One "trailer shop" suggestion was to simply...

NOTE WEB PAGE HAS BEEN CORRECTED I have posted several pics on the following webpage. http://hometown.aol.com/wildwest2a/trailer.html Actual length of material to be removed would only be 2 feet rather than the 3 feet previously stated. Also, I wish to remove 5 inches high, leaving 3...

Application: Aluminum gooseneck horse trailer incorporates (2) 6 foot long 8 x 2.25 x .25 6062 aluminum C channel beams (sitting long side vertical) from each of the front corners of the box, coming to a point (forming a triangle with the front edge of the box) where they are welded together and...
