This one took me awhile. 1/2" thick Red Oak on 1/4" BB backer. Rather then using "rails" like the plans, I when with a full sized backer board. Cut with #3 Pegas MGT blades. I usually get my R.O. from the local big box store (Menards), but I have not been pleased with the quality lately. Uneven coloring and excessive warping, etc. Problems I never have when I buy from Ocooch Hardwoods so I will be ordering a lot more from them this year.
