I decided to build my own set of car ramps as most sets you can buy are too steep and narrow for most modern cars. I came up with the idea of a flat pack design that is self jigging which would hopefully minimise distortion and mean each ramp turns out the same.
I used the trial version of Turbo CAD, and drew out a design with interlocking tabs for 3mm mild steel sheet. I live near a laser cutter so could collect the parts instead of paying for postage. Each ramp is made from 5 parts + lengths of 20mm x 20mm x 3mm angle cut to 300mm long.

Cable ties used to hold the parts together while they were tack welded.
Then stitch welded together.
20mm x 20mm x 3mm angle tacked in position using a length of 50mm x 3mm flat as a spacer.
The end frames are made from 40mm x 40mm x 2.5mm box section for the base and 30mm x 30mm x 2.5mm box for the top and a 4 ton bottle jack.
Ramps grit blasted and powder coated next to a ramp that you can buy.
The ramps are 95cm long x 30cm wide x 25cm high, the ends are 50cm long x 25cm high collapsed and 38cm high raised.
