I was looking at free woorworking plans,
and came across this plan for an "A-frame rabbit hutch" which is almost identical to many ark/tractor plans. I wish I'd had it last weekend
when much experimentation was necessary for our ark. Much timesaving work already done here with
guesswork eliminated- materials list with cost,
instructions and diagrams. Nice.
