DIY full length ramp

I made mine out of old railway ties, the finished height is 3.5 ft off the ground. The ramp angle is quite low, I'd guess around 12-15 degrees. The chin spoiler barely makes contact but does no damage. It's perfectly level on top, and strong enough to support a one ton pickup truck

I'll never use old railway ties again. It was truly backbreaking work. Next time I'll weld something out of steel. If you use 2x12 it should be strong enough, make sure to double up the boards on the outside.

 

I saw some long ramps at a swap meet that were so inexpensive, I was sorry I made my own. Search the internet. What I did was to make starter ramps for my standard ramps, triangular shape. I made them by laminating 2x4's, screwing them together with drywall screws. They extend the ramp a little over a foot, and allow me to go up forward or reverse. They contact the ground on one face and the ramp on another. As for something home made, to hold a car up while I am underneath? made of wood?, the only thing I would trust would be solid wood, like laminated lumber or railroad ties.

 

Of course, if the ramp is outside, you will have to use treated lumber and treated screws. Otherwise it will quickly decay
