Q. We just started processing some cherry lumber that was planed S2S by the supplier. We are seeing a small number of checks developing, especially in the flat sawn pieces. We are really perplexed as to what is causing this.

Q. We have a machining problem. As we machine a piece, it is good until the last half inch. At this end, we all too often get a piece that chips out all the way to the end. Where should we look?

Summary of the pest, the problems it causes, and controls.

WEST PALM BEACH, Fla. -- Popular FDMC columnist Gene Wengert, aka “The Wood Doctor,” will make a house call during the Wood Pro Conference.

Q. We are processing wenge and have what looks like sap or resin pockets so that the finish does not darken like it darkens the rest of the wood.

Q. I heard that you said in a webinar that the variation of moisture content for lumber coming into the plant should be 0.3 standard deviation. Is this correct?

Q. What is going on with wood prices? Do you have a forecast?

Q. What humidity should we keep in our manufacturing plant? Is this 24/7 or can we have other values at night or during weekends?

Q. Once in a great while, we see a white paint turn dingy in small regions on a panel. Oftentimes this dinginess shows up a month or two after painting. What is this?

Q. When our crosscut or chop saws cut the end of oak strips, the end has many small splinters. Do these affect or cause the joint failure we see?
