Speed Dial Lock
July/Aug 79 (Revised 11/98)
the summer months, when your shop is open, children may venture
in to see all that interesting equipment. Not only is this dangerous
to them, but it can also mean you might be faced with a repair bill.
trouble starts when the kids turn the machines on or turn the Mark
V speed control handle. To prevent little hands from turning ON
the machine, always remove the key and put in a safe place. On older
models, use a safety padlock that slips through the holes in the
for the speed dial, you can keep this from being turned by making
a simple lock out of flat steel. A 25/32" hole in the lock fits
on the quill feed shaft under the quill lock handle. A 1/2" hole
fits over the knob on the speed control handle.
install, remove the quill feed lever and the quill lock. Then, with
your machine running, turn the speed dial until the knob is at the
top of the machine. Slip the speed dial lock over both the quill
shaft and the knob. Put all the other hardware back on, and your
machine’s completely safe!
