Some questions about Alburnum

Jason McSpadden

>Yesterday I was trying to read some of Alburnum's website, alot of it comes in phonetic greek, but the english had these words about a joiners bench, "The bench top is 2-inch thick spruce board, 10-inch wide edge butt joined with dowel reinforcements. The front apron is the same material the bottom edge having a fine bead shot at the edge. This beading also relieves tension within the wood and keeps boards and beams from warping."

My questions are, "What does that last sentence mean? Is it true?

I'm wanting to build a Nicholson style bench that this seems to describe but I'm unsure what he means by this. Is it something that I should do?

Thanks,

Jason

>Reminds me of the rabbet(s)on the back of baseboards and molding to prevent cupping, but a fine bead is a far cry from a wide rabbet.

>that the backing out on baseboards was primarily to ease fitting, in case of irregularities in the plaster/drywall joint.

>I've heard from a few diferent sources that it's for both (one source being the shop where I buy my custom moldings). On smaller moldings the rabbet can be almost the whole width, so in this case it's obviously more for fitting than anything else, but on some wide baseboard I've installed (9") there were three 2" rabbets equally spaced across the width (no wood taken off between them), which hardly helps with fitting at all.

>It's for both. Like when putting on 12" wide siding I have ripped several saw kerfs in the back to keep everything for warping, but if you have a gentle full width relief that is to make it fit better. The best thing for getting trim to fit drywall is a good bead of calk, most of the time it won't follow the wave pattern of the wall if it has any thickness at all. In offices they contact cemeted the mplding on which makes for a tight fit.

Your equally spaced ribs do help with fitting to a flat surface. You get enough surface to support nailing but everything else is relieved in case there are minor things like a slightly exposed screw or blob of plaster, anything that might be high.
