Making the sled for may BB mortar, Got a great deal on 2 in. hickory planks. 2 in. thick X 10 in. air dried for 15 years, I cut and planed out 4 pieces 1 3/4 thick by 10 in. by 30 in. long, Glued 2 pieces together for each side that is now 3 1/2 thick, Them 4 pieces is about all you want to lift, On the inside is 4 pieces of white pine,planks that will float,, pine to make it so I can lift it. Bolted together with 5 , 1/2 in. ready bolts. Thinking now after reading a different thread here, is the hickory okey, Thanks- Joe
