BGK, I know what your saying on those deck boards! I buy almost all my lumber from Menards. I still call around for prices, and menards always blows home depot and lowes out of the water on prices and the quality of the lumber. Ya and about those my buddy works at a dairy and he gave me about 5 barrels that were full of vannilla flavoring. smelled real good! A 3/4 pipe thread PVC plug works great for the center of those bung plugs. I also used silicone on the threads. probaly over kill but didnt want thise leaking. The plugs were cheap. like 4 for a buck.
Mine also came from a dairy. I have a couple that dont have the caps, but my barrels are wierd one side is fine thread the other is coarse, so it could be real fun finding caps.. I planned to silicone mine also.. My holes are alot bigger than 3/4 maybe 1 1/2 will work on the coarse one.. Thanks for the tip.. Did you say you got 15 barrels under your dock?
