I suggest the new experiment:

Seal test boards with shellac – all sides, one side and end grain, one side only. Finish another set with BLO, no shellac. Another board with waterborne lacquer (all sides). Keep it over one season. Also, measure waterborne-finished board immediately and after some 2 weeks.

Tom,thankyou for letting in your feedbunk,lol burner.That was a very wise test.I built a rolltop desk out of ash for my daughter here in Iowa in 2004,it was a beauty,still is but they moved to Las Vegas in July of 2005.Temps were 110 with 7 to 10% humidity.She called one morning in september stating theres a crack in the desktop,she was heartbroken thinking they did something wrong.but tried to asure her it wasnt anything they did.And thought it had it be the humidity.Its hard to believe but when we visited them in Oct.the crack was about 3/16s but not very noticeable,so thats how its stayed.

I thought what is called 4 foot wide MDF board is actually 49″ wide.

You mean the MDF expanded? Wow, that’s pretty cool!

I will say this about MDF. I bought a 4×8x3/4 piece of MDF at a local lumber yard and they loaded it into the bed of my truck. When I got home the piece was actually stuck in the 4′ wide opening between the wheel wells of my truck. The MDF had been stored in an outside situation. I never measured the MDF nor did I measure the distance between the wheel wells; but I would say that the piece of MDF was between 1/2″ and 3/4″ wider than it should have been.

I’ll be interested for sure to see the results for finished samples. It sure seems like a shell of polyurethane would keep the moisture out (or in), but who knows.

While you’re at it, I’d also like to see the same experiment run on MDF, plywood, and particle board. I believe these are all considered to be more stable than solid wood, but are they really? And if so, by how much?

interesting indeed.

I have a set of french double doors that in the winter have a good 1/2″ gap between them, and now that it’s been raining and decently got, they touch when closed. Sometimes you can barely even get them closed. This on Long Island, in New York.

Very interesting, Tom.

I notice Ash is pretty stable in spite of high rel. humidity. That can be helpful here where we have large seasonal changes.

Yeah – definitely an interesting experiment. I’ve got some other plans for cool experiments planned for the future. This could be fun!
