A wheelchair ramp's surface is two sided MDO (medium density overlay) plywood. It extends over a step from the door sill to a brick walk. I chamfered the end of the plywood slightly at the brick walk, but there is some concern that the end may be a trip hazard.
As a short term solution I tapered a 4" wide piece of rift red oak (what I had on hand) from 3/4" thick to 1/16" at the other edge. Red oak is not as weather tolerant as white oak, but I'm more concerned that it may split before it rots.
Aluminum and other metals is not an option because of the likely marking of the bricks. As a long term solution I've wondered about essentially making 3/4" white oak plywood by using urea formaldehyde glue on layers of 1/16" rift white oak with alternating grain directions.
Does this sound reasonable? Thanks.
