AJ talking about his all time favorite shop tip reminded me again of my all-time-best, award-winning, life-altering, if-he-never-came-up-with-anything-else-in-his-whole-life-it-would-be-worth-it-for-this, shop tip.

I' sure I mentioned this at one point, but it's so good it bears occasional repeating for the benefit of those who might have missed it the last time around. A few grains of fine sand dropped into the glue line before clamping boards together will eliminate the frustrating tendency for pieces slipping around under clamping pressure. This has saved me countless hours of frustration and I'm still working on the 10-lb. bag of fine washed aquarium sand I bought for four bucks back in 1978.
