I am planning to build bookcases, 7' high by 4' wide and 1' deep using 3/4" oak plywood and 3/4" oak solid-wood facing on the edges of the sides and shelf facings. My question is whether I can safely glue the facing to the plywood without fear of expansion and contraction of the solid wood. Art Daniel via the internet You have absolutely nothing to be concerned about with regard to the solid-oak facings on your plywood edges. The solid lumber is simply not wide enough to expand or contract with noticeable movement. You might want to give some further thought to the 4' shelf length if you plan to load them down with books or other heavy objects. The shelves could sag some, especially if they are adjustable and therefore not supported along their back edge. Any length past 36" on 34" ply that will see real weight is prone to sag. Some cabinetmakers would say that any length beyond 30" risks some sagging. — Steve Shanesy, editor and publisher Does a Damaged Lever Cap on a Plane Hurt its Performance?

Two spots were knocked out of the left bottom side. Is this a bad problem? Can or should I try and replace the lever cap? James Lissner Bellevue, Washington Damage to the lever cap isn't as much a problem as damage to the chipbreaker (another problem on older planes). The main job of the lever cap is to hold the blade and chipbreaker assembly tightly against the frog. Its role in removing shavings is minimal. However, if the damage is severe, it can interfere with the removal of your plane's shavings or even compress the chipbreaker and blade 16 Popular Woodworking June 2002 |
