My jack and stands were tied up under my 2002 Civic. I have plastic ramps in the Accord trunk 3.5 hours away. My new schemes and plans weren't working. I just bought a 2x8, cut it in half, cut each half at a 45° angle, glued the pieces together one at a time, clamped them, and then screwed them together. Two 2x8s raised Mom's car just 3", but it was enough to change the oil, and if one of the ramps went under the car, it was only a 3" drop.
This is the closest image I can find to the ramps in the garage:
Is that a 2x6 on top, with corners from a bed frame attached to the end?
Somehow it looks like a 2x7.
I watched this video just because the thumbnail confused me. He just built simple ramps, but they are in two pieces, with hinges in the middle, and a weak latch that couldn't possibly hold up as long as the rest:
The comment section was weird. People insisted this was better than metal ramps and less likely to move while you are trying to climb it, which would largely be dependent on the weight, and steel ramps weigh more.
One guy said that a stack of 2x8s were too heavy and needed holes drilled in them.
One guy absolutely insisted that flat 2x8s would fail with part of a vehicle on top of them.
Maybe Project Farm will test ramps some day, but I am sure that he has 100 more interesting ideas.
The guy in the video said he had 3" left from each 2x8, which he could have screwed to the 3" board on the top of the ramp, but they wouldn't fit together the way he wanted.
He said that he didn't cut the boards at a 45° angle because cars can climb 2" boards just fine, but someone pointed out that a car wouldn't have a problem going over the top board.
I kind of want to see Project Farm test chock blocks, but that sounds even more boring than ramps.
Someone tell me how well 2x4s work for chock blocks!
