An airplane cradle is indispensable for holding the fuselage during assembly, maintenance, or simply
while attaching the wings when you get to the fl ying fi eld. With its adjustable arms and cradle bases,
the Carl Goldberg Super Hold’em suits this purpose for most models up to “giant-scale.” And the
storage drawer and tool tray convert your Super Hold’em into a miniature, remote work bench for
working on your plane at the fi eld. The Super Hold’em can be assembled as-is, or fi nished with clear
varnish or paint. If applying a fi nish, note that the parts fi t is tight, so the notches in the cradle bases
and cross bars will have to be widened accordingly. This can be done with a strip of coarse sandpaper
glued to a sheet of plywood, but use care not to widen the notches too much. Otherwise, the parts will
fi t loosely and the stand may not be rigid.

1. Remove all the parts from their laser-cut blank sheets.
For the best fi nish, take your time to cut around each part
with a hobby knife where necessary.

2. With the exception of notches and slots where the parts
fi t together, sand the edges of all the parts smooth.

3. Glue the guide sticks to the large cradle arms with the
bottom of each stick even with the bottom of each arm (be
certain you have selected the large arms, not the small
arms). And it doesn’t matter which side of the arms you
glue the sticks to—there isn’t a right or a left. Optional:

Sand the sticks even with the beveled edge of the arms.

4. Use pliers to fl atten the spikes in both 6-32 blind nuts.

5. Mount a large arm and a small arm to each cradle base
with a 6-32 screw, a washer and the blind nut.

6. Optional: If you prefer the arms to remain level (without

the ability to tilt), glue the remaining two guide sticks to
the cradle bases even with the arms—be certain not to
inadvertently get any glue on the arms.

8. Glue one tube to each of the four vertical arms. Fit the
remaining two tubes over the horizontal portions of the
arms, but do not glue these tubes on. Note: If using your

cradle for a large model and spreading the arms wide,
longer pieces of horizontal tubing may be used. These will
have to be purchased separately.

Set the cradles aside while assembling

the cross bars and drawer.

7. Cut the foam cushion tubing into six 3-1/2" [90mm]
pieces. Slit each one all the way down.

9. Working over your workbench protected with a sheet of
clear sandwich wrap, a plastic bag or Top Flite® MonoKote®
backing (so glue won’t stick), assemble the “box” that will
contain the drawer. Glue the parts together. For now, don’t
build up large fi llets of glue–use just enough glue to hold
the parts together for handling during assembly. Later, more
glue may be added for reinforcement. Also, don’t worry
about getting the assembly perfectly “square.” Everything
will true up when you join the box to the cross bars.
