price! Sometimes those accessories can be found very cheaply because they
have wandered away from their parent machine over the years. All the
accessories I've seen have been well made.
As a lathe, the Shopsmith is a pretty good one for spindle turning. I
bought a faceplate from the company about twenty years ago, back when they
had a chain of stores. The 10ER, at least, has a 5/8 spindle diameter
that takes all kinds of tooling, including a fair amount of stuff from
other companies. The drill chuck, faceplate, sanding disc, etc. mount
with a setscrew against a flat on the spindle. Sawblades mount on a
threaded arbor between compression washers, with the arbor/blade assembly
mounting on the spindle.
Washing machine motors are a great way to power your shop. They're
generally 1/2 hp, and if you get them out of top-loader washers you have
the option of mounting them with the shaft vertical, as you want for a
drill press or spindle shaper. When a washing machine craps out, it's
almost never the motor that went wrong!
When you tear out the motor, be sure to get the wiring diagram! It's
usually on paper and glued to some surface on the inside of the machine's
shell. Cut out the piece of sheet metal drawing and all if you have to.
You need this because washer motors have a great many color-coded wires.
Figure them out and you often can select two speeds, and reverse, the
motor with just switches. Each company does it differently, which is why
you have to use the diagram to figure it all out.
If you feel you need more than 1/2 hp, there's no law says you can't belt
two or more motors to one shaft. You may want individual switches on each
of the motors--motors draw more current to start than they do in normal
running, and if two of them start at once you may find yourself blowing
the breaker. If this happens, try switching one motor on and then
starting the second after the first has come up to speed. If things still
blow, you can settle for less power, lead an extension cord for one motor
from another circuit in your shop, or rewire with heavier-duty wire and
breaker. "Slow-blow" breakers are also available and a good idea for
power tool circuits; they absorb short-term overloads of a few seconds
(like starting a motor) while still keeping your wiring from overheating
and starting a fire somewhere.
