pic: Another Cheap Wood Frame Idea

If you think it could use improvement, I suggest you build one yourself, and see where the weaknesses are, and let us know how to make it better! After all, it only costs $20 and an hour of labor. (yes, I'm making a big assumption, that you have the machinery necessary to build it....but that is mostly the same machinery that has been required to build bumpers the past two years)

could you tell us the dimensions?

ill see if i can get to home depot today or tomorrow

did you apply the glue then staple it?

luckily gorrilla glue is cheap

The dimensions are based on a few things that you can probably be the best judge of....length and width a bit less than the maximum allowed, the inward offset of the sides is enough to allow the wheels and chains of your choice, and the height is enough to fit the transmissions in. We chose 26" x 36" x 5.5" overall size, and 2.25" side offset. You can do whatever you want!

Yes, we used Titebond premium wood glue, because there were three bottle of it in the fab shop, and we used 1/4" crown x 7/8" staples because they were in the pneumatic staple gun, and it seemed like they'd work. You could use nails, brads, small wood screws, other sizes of staples, etc. Just beware that using a fastener into the edge of plywood is not very strong, so getting a good glue joint is kind of important.

And thanks for all the great info Rick!

ever thought about taking a piece of aluminium angle for each corner and bolting the wood to it, as well as gluing the corners

I've been thinking about the corners, and I still think that the triangular gussets on the top are all that's needed. And they are needed, they add a LOT of strength and stiffness to the design.
