Corner legs are used for legging up lower
platforms that are 12 to 18 inch tall. We usually make the corner
legs from scrap 1 x 6 stock , cut to length and stapled together
with 1 1/4" narrow crown staples.
These legs are then stapled into the corners
of platform frames on one side only and then screwed on the other
side.
Note: if both sides are stapled the legs
will not come off easily when struck. We want the students to
be aware of the needs for a successful strike as the scenery
is constructed.
A bottom stringer may be added to 18"
platforms but not to 12" ones. No additional cross bracing
seems to be needed.
