What's better, bend the side rails or cut them ??? to form the angle.

bend it
its alot smooter well it looks that way
i would just about think its easier to bend it but i dont know
to bend the rails for my ramp the welder person just took it to some place to bend it
some machine
but i read in frmx that to bend flintys ramp they just got the rails and got a few blokes to swing off both ends to bend it

i don't think that was for the rails i think it was just for the actual ramp surface stuff

lol nah, it was for the metal man, u just screw the suface onto the metal and it goes into shape ;)

and yeah FMXXX, i would say that bending is better - but only if some fabrication place is building it.

It very simple to cut it (jsut like on sliders site) and get it perfect

well i think that idd get a fabrication place to bend the metal if i built another ramp, cause a. they could get it perfect cause they have special tools for that ect and itdd be realitivly cheap i think?
b. when we bent out metal, we had a problem with it twisting when we bent it so it took lots longer to put it together.

I pay 40 bucks per stick to have it bent. One reason is due to a non constant radius of my angle.

When doing it the old school way, be sure all of your cuts are square or you could have a pretzel. Also, make sure the weld (the dark line on every piece of square tubing except for Chrome Molly) is on the bottom. Don't cut this or it will twist more.

I helped Vince Morgan cut and bend rails for his Rev.3 ramp and it took us only 2 hours to finish 2 rails. One was slightly bent, about 2", but was easy to straighten as we were adding the cross supports. We also had 2 welders going; that saved a lot of time.

im not sure wether all fabricators do it this way but to get the bend i wanted they said to get string or draw a line from the top of the lip to the bottom then from the middle draw a line from the string or line thing to where the surface is to get the bend
prolly dusnt make sense
but is that wat the other fabricators do?

hey slider (or anyone else)?would it work if i made the supports like to the hight that they need to be then welded them to the base and sides. next i lay it on its side and bend it to the supports and weld it down. get what im sayin? will that work? has anyone esle tried it?

If you're saying what I think you're saying, that's what we did. We welded all of our uprights up and got the basics of the frame, and got 1"x2" and bent it to the uprights and tacked it and welded it. I guess that warps it or shortens it somehow.. but ours came out exactly how we expected it to...

RedBull, I only did this one time, Rev.1, and ended up with a rocking horse. Then when I cut the supports to make the bottom straight, the angle increased by almost 2" at the sweet spot.

when we had 1 side of our ramp done, we tacked the main frame parts (the vertical and horizontal peices) to the one we had done. then we welded the bottom of the peice we needed to bend to the frame part and heated it in the approrpriate spots and pounded on it with a BFH (large hammer) and that worked really good cause you dont gotta keep moving it and bending it to see if its right.
