I did this at TechShop Menlo Park. http://www.techshop.com
have a 18 year old dog who has trouble with stairs so I needed to build her a ramp to get in and out of my new house boat.
Step 1: Cutting Wood
We started with one bog long piece of wood and cut it into 3 pieces to make a collapsible ramp.
Step 2: Hinges
Srewing in hinges on either side so the pieces would fold.
Step 3: Latches
Installing latches so that the board would stay flat for the dog to walk on.
Step 4: Doggy Ramp Is Ready
I will staple some carpeting on it so that she has better grip to walk on. This will make my baby's life a little less painful.
