Look in the build section there is picture after picture with full discriptions on how to reinforce a pan stamped chassis.

Wheather stamped or not reinforcing is the same, look at the examples in the build section.

Flyinb is working on a Murry, and it is very flexy laterally through the center.
When you run the tube the length of the frame, how des that stop the lateral flex?

I don't know how it works, but it has always made a big difference in all the ones I've built.

In order for the frame to flex laterally, it has to flex from end to end on either side Rooster, by stiffening the chassis and preventing the end to end flex it removes lateral flex as well.

Likewise when you stick a prepared front end under one, and a heavier rear axle, that works into the equation as well, with the sides reinforced.

If the pan is that light you'll probably also want to reinforce the engine mount using a little heavier plate under the engine, especially if you're running a modified engine, and you'll want to add a heavier plate under the tranny tieing that into both side supports. (unless you run a transaxle of course).

Everything you weld in there stiffens the chassis a little bit! The sum total of which adds up to a lot.

OK,

I was just thinkin, you see most of the flex in the chassis diagonally from corner to corner, across the middle section where the sides are not as tall under the running boards.
If you built an X brace in that area, maybe you wouldn't need the extra weight all along the sides.

I agree it would be strong.  I would think it would probably screw up your clutch setup though.  Also, all I have ever done for reinforcing is run a piece of angle iron or 2 x 1 square tube up each side.  I cant imagine you wanting to use much less than that for the diagonals, so you would actually end up gaining weight as the diagonals are longer than the sides themselves

Thats an excelent way to do it, and that frame definately has no flex, also the holes kept the weight down. Only down side if if your running a belt type set up you could run into problems. But in that case, he was running a horizontal motor.
