Congratulations! you have completed the kit for the Harp Wheels. Now you’re ready to move
your instrument across mountains and valleys.
Engage the cam on the wheel, and make sure that
it prevents the wheel from moving while it is in the
locked position. Also, disengage the cam to ensure
that the wheel spins freely while the cam is not in
the lock position.
___ 15.
____14. Tip the cam forward about 5 degrees. This will help
hold the brake in place while you drill the top pilot
hole. Align the brake next to the wheel. Let the brake
rest on top of the wheel. (fig. 14A)
Keep the brake aligned and use a 7/64” drill bit to
bore a pilot hole, in the top hole. Then insert the
1-1/4” wood screw into the pilot hole you just drilled.
Do not tighten the screw all the way down.
Repeat process for the the lower hole. Be sure the
brake stays aligned for this step.
Once both screws have been inserted, you can tight-
en them down all the way. (fig. 14B)
Repeat this process for the other brake.

FIG. 14B
Insert the carriage bolt into the main brake part. Put the remain-
ing 1/4” washer between the main brake part and the 1/4” lock nut.
(fig. 13B)
Use a 1/2” socket or wrench to tighten the
lock nut. (fig. 13C)
This nut needs to be tight enough to keep
the cam from moving when it’s engaged
on the wheel, but loose enough to be able
to move it without too much effort.
