Planing Glued-Up Stock

Figure 21-15. If you wish to plane glued-up stock, scrub the wood with a wet rag while the glue is still wet. Be sure to remove all the glue on the surface of the stock. If any surface glue remains after the glue dries, remove it with a scraper or a belt sander. Warning: Allow the glued-up stock to dry at least 24 hours before planing it.

Your planer is designed for planing wood. Other materials, including glue, will dull or damage the knives. However, on those occasions when you need to true up glued-together stock, follow this procedure to minimize the damage to the knives:

After you glue up the stock, scrub all the glue off the surface with a wet rag (Figure 21-15). This will prevent glue beads from forming on the surface of the wood. Allow the glue to dry at least 24 hours; then check the stock for any surface glue you might have missed. If you find any, remove it with a scraper or a belt sander. Warning: Glued-up stock must dry for 24 hours prior to planing. If it doesn't, the stock may come apart in the planer.

When you plane glued-up stock, take a shallow depth of cut (1/32" or less) and use a slower feed rate than normal.When you're finished, check the planer knives for built-up pitch and signs of wear.
