I have a fabric dyeing project in mind where I want the fabric to be
removed gradually from
the dye bath. My thought is to tack the fabric to a dowel, suspended
with nylon or cotton line and
wind the line onto the stem of the motor or some sort of spool. I don't
want to spend much
and it would be ideal if the motor had adjustable slow RPM's. Would be
okay if I could scavenge
from something easy to find.
The time would be pretty easy w/ one of the household security
lighting mechanical timers if don't need it to be exceptionally
precise (which doesn't sound as though would be).
A variable speed motor could be arranged by manipulating a variable
speed drill it would seem with some cams, etc., ...
Here are my links to places that sell gearmotors:
In order to embark on a new course, the only one that will
solve the problem: negotiations and peace with the Palestinians,
Gee.....I saw one possibility (gadget gurus would get to the right item
more quickly). I had not
remembered that there are still clocks with hands. Just a couple of
months ago, I made a new
wall clock for the kitchen. Is a battery clock motor strong enough?
Would a cheap electrical
clock be more or less strong? I guestimate the weight of the wet fabric
to be no more than a
pound, but I don't know about pulleys and torque and all that stuff.
I doubt the $2.00 clock mechs you can get at craft stores will lift
anywhere near a pound. You might need something like a grandfather
clock mech, which might run you more than you want to spend.
Besides, you asked for "adjustable RPMs" While some clocks mechs have
a "faster-slower" adjustment, I'm guessing the amount of adjustment
would be minuscule.
Slow is easy, a motor out of an ice maker or some other small gear
head motor will work. Mail order outfits like Hosfelt and All Surplus
sell these pretty cheap. Adjustable is tougher. That either gets you
to a stepper motor, gear head DC motor or some kind of variable
frequency drive cobbled up from a 555 or similar time base.
Attach a bucket to the line and a couple of pulleys. Trickle water
into the bucket from a slow hose.
As the bucket fills, the fabric will be drawn out. Adjust the length
of the line and speed of the trickle to match your needs.

I like your idea but would get a plastic bucket as an Ice Cream
container. Fill the bucket with water with a hole in the bucket.
Fill the bucket and put time markings on it. Fill to the time desired.
Use the bucket as the timer.
