My daughter has a 4”x4” riser in front of her garage that the door closes on and she needs ramps to get up it on the outside and down on the inside. I think the riser is to keep the water from flowing in there when it rains.
I made some plywood ones about 8 yrs ago and now the outer ones have deteriorated so I thought I’d try another design to see if they last any longer.
These ramps are made from treated wood and the overall size is 4”x 15” x 30”. There are 10 wedges bolted together with 3/4” pipes on the inside that are drilled tapped to 5/8- 11 thread. the 3 rd photo shows the pipes and bolts used to pull them all together. I added some 1/2×1” x 20”C-channels to spread the pressure to the thin ends where I could not put a bolt
The 4th and 5th shots show the quickie half sled I made to cut the wedges and the last shot is the drill set up to make the holes centers consistent. They all lined up very well. You can really get a lot of pressure with those big bolts, too. I was going to use threaded rod, but I did not want any rods ends sticking out the side. This was more fun anyway!!
