New to the site, already appreciate the wisdom I've found.

Starting a big project that I wood appreciate some thoughts on.

I'm building a 100' x 6' seawall (with deadman/ tiebacks) on a finger lake in NY. I'm now in the process of logging the black locust for the wall out of a small woodlot we have. Many of the trees fell year's ago and those are the ones I'm dragging out first. I will then cut some standing trees for the remainder.

Then the plan is to have portable mill saw the timbers. I'm invisioning 8-10" beams on the bottom that will taper to 5-6" on the top (considering the size of logs I have to work with). I would like flush face on the wall. Should I only have the mill cut 3 or 4 sides? 3 would give more material in the wall, 4 would give me the flxability to flip the timber for a possible better fit when building the wall.

I contacted Bill at logfinish.com about products that I could use to preserve the locust. He checked with some specific product specialists / chemists and they all said that due to the density of the wood he had no stand out suggestion. A Borate based product would not penetrate well. He did say a log pretreatment would last approx a year and a deck sealer would be a possible option on the face of the wall. Essentially, just use the natural design of the wood for protection. The wall will be built in December (when the lake level goes down). Should I be worried about checking/ splitting? Any other thoughts?

Thanks, Lavarock
