pressure against the drive track. The tires were bald from
use when I bought them and I kept the air pressure in
them low to provide better traction.
IMPROVEMENTS: After using the turntable for several
productions, I find it would have been better to use a
gearmotor with a top speed of 45 rpm. This means a
sacrifice of inch/pounds of torque but I feel it would be
worth it. As it is now, one half turn takes 23 seconds. A
faster speed at times would be more desirable.
I also found out that crossbracing with 1 inch flat
slotted steel on the ends of the trusses was needed since
the overall height was not supported by the verticals alone.
I used medium weight slotted steel for the trusses. A
1/2 inch deflection occurred when I jumped at the middle
of the truss. While it is not a problem in terms of breakage
it did cause vertical scenery to wobble a little. Perhaps
crossbracing each truss will alleviate this problem. I would
also suggest using the heaviest weight slotted steel.
The caster wheels are made of semi-steel with sharp
edges that tend to cut into the track. I would recommend
a hard composite wheel with rounded edges for this
problem.
CONCLUSION: My experience with slotted steel had
been limited up to this point. I have always thought the
cost to be prohibitive. In addition, the construction
techniques needed for irregular or angular shapes seemed
to be too complex. However, in the case of the turntable,
it is my opinion that the slotted steel angle is an excellent
structural material. The cost, in terms of ease of assembly
and usage, is well worth it.
In my opinion, a turntable (figure 11) is an excellent
scene shifting device for the stage without wings or flies.
