Dave, I was able to replace all the wooden things in my Burro
with one 4 x8 sheet of 1/2 inch birch plywood. I did reinforce the table top with some oak strips. I layed all of the old wood on the plywood first, making sure to get the grain on the cupboard doors going the proper direction and then figured out how to cut to maximize the use of the wood.
I used spar varnish on anything that might get wet - the storage covers. On the table top and cupboard doors I used a clear water based polycrylic. Congratulations. I hope you like your Burro
as much as I like mine.
