Requirements: able to transport it out to the island of Nantucket, put in to place for wheelchair accessability and store when we're not there.
This project might be useful to anyone who has a friend/loved one in a chair that visits occasionally
Step 1: Parts
Something to think about if you're building one of these. The top ramp section must go flush up to the door step but the lower ramp section must be high enough to clear the end of the step, allowing it to line up with the end of the upper ramp.
So, a sheet of 3/4" ply (smooth on one side) cut in to 3 sections. 2 of 48"32" will make the ramps and the other 48x32 will be used for the sides and ends.
Some 2x1" for securing the end & sides
A load of 1 1/4" deck screws
Acrylic deck dust to provide a non slip surface.
