I really haven't used a biscuit joint much and am curious about its strength. I am needing to construct 4'x8' theatre flats that are double sided and covered with muslin as a piece of stock scenery. So I need a flat that is somewhat durable. It is been suggested that I use a half-lap joint, but those are a pain in the posterior to make without a dado set on my saw. Question is...is a biscuit joint sturdy enough for use on a soft theatre flat? Lord knows it would be the least painful.
