Thread: "Sticky in process"... Miscellaneous facts about drying lumber

  1. #16
    About log sealer, no retailer in my area has any for sale, and looking at it online is expensive. Ran across a formula once for a wood preservative, had you take a quart of linseed oil, a piece of parafin wax melted, think it was a cup full, and remainder paint thinner, mixed up to make a gallon. Found if you just melted the parafin, and poured it into the thinner, it stayed liquid. So, does anyone make their own log end sealer this way?

    Jim, I haven’t but I know that there are a lot of homemade formulas out there. One nice thing about the commercial end sealer from UC Coatings or Bailey’s is that it evaporates off of the lumber during the kiln sterilization schedule. That is beneficial for commercial milling and drying concerns because the lumber does not have to be trimmed before planing.

    You can order a 5 gallon pail from Bailey’s for around $80.00.

    I tried a modified version of what my uncle did drying wood out of his woods. He used a large clear plastic tent with pallets on the ground. and stacked racked lumber up to about 8 feet tall.
    He put a humidistat with an exhaust fan inside tent durning the summer. He closed the tent and left small holes at bottom. The sun heated air raised the temp and the fan removed moisture.

    I created a 2 x 2 wood framed box on top of sawhorses, stacked the wood (550 board feet green about 1 week from saw mill) with slats inside the wood frame. Then I sealed up the frame with plastic leaving a humidifier on one end with a duct taped drain line out the bottom.
    I started with the moisture setting of 65%(that's the highest setting), and left undisturbed for 3 weeks. At each 3 week time period I adjusted to a slightly lower level till the lowest set point.
    I felt there was plenty of air flow as the dehumidifier fan circulated enough air that the plastic fluttered over box frame. The ash lumber felt like a feather compared to when I stacked it.
    The dehumidifier seem to add heat to the box from running constantly.
    This was my first attempt at drying lumber.

    I found a plan for the Virginia Tech Solar Kiln, by searching solar kiln virginia tech. Has measurements, just build away. Mine has the door hung, need to find the vent covers, Menards is OUT. Frame the openings for the vents, insulate put the plastic sheeting on the doors, and sheet the inside of the doors before painting. Handled some sackcrete bags Saturday, can hardly walk now. Guess it will be a while before I get this thing finished. The rest of the kiln is finished inside, was hoping to get the thing painted soon.
