Don B's Ramps.
We're proud to have Don B as one of the ramp plans crew. He's built a lot of stuff and has helped answer many questions that readers have sent in. He's also sent in the best construction photos we've gotten.
First there's his spine ramp which he's since torn down. This page also has some thoughts on the ramp and on ramps with tight transitions.
Second and most recent, Don B teamed up with his buddy Master Carpenter Don M, and the professionalism really starts to shine. Together they built Don B's new mini ramp. ( It actually has very similar dimensions (almost exactly) to the "R.P.D.O. mini II" ) What we have as an awesome photo journal of the entire ramp building process. This is truly one well built ramp.
