your first, basic Masonite slider, sand the narrow edges into a
45-60-degree angle so they’ll slide and not bump and stop when
hauled around the layout. Draw a center-line down the back
(smooth) side of the Masonite slider. Measure in three scale feet
from both long ends, and mark.
You’ve now established where the roofing nails will be epoxied.
Roofing nails are especially friendly for this job because of their
great, big, flat heads. Measure the distance between the nails’
points to make sure you’re on the mark, it should be a scale 12
feet. Then leave the epoxied nails alone for 24 hours so your
five-minute epoxy cures to full strength.

drilling with a hand
drill or drill press, a
little cutting oil, while
not necessary, is ex-

3/16” drill bit allows
the nails a little slop,
which is good; we
don’t want our sled
binding. And calipers
are always good for
getting true measure-
ments and starting
holes, although not in
steel.
