Do any of you know where or if someone supplies drying motors that are variable speed. In the 6 to 30 rpm range?

Sent you an email, Mark

Mark,
One of the best sources is to use a DC gear motor with an adjustable DC power supply to drive a motor that has that speed range.

Good luck

Check out surplus stores in your area, as well as on line internet sites and @#$%& sites for the best prices.

I was able to find a couple very heavy duty DC gear motors with a speed range of 0-50 rpm at a very good price including the controller. In this case, the controller plugs into AC power and the dial on the controller adjusts the speed from 0 to the maximum 50 rpm.

I just did a quick search and here is a nice 30 rpm 12 volt dc motor available at a decent price:

Connect this to an adjustable 0-12 volts DC power supply and you will be set.

In case you haven't considered it - a power wrapper does a nice job of applying finish.
If you have a power wrapper, you can simply leave the rod in the wrapper until you finish applying the finish and then move the finish applied rod over to your slow constant speed dryer.

This way, if you want to speed your finish application to 50- or 200 rpm, you can do so.
I generally do this and normally use a finish speed of about 150 rpm. This rpm allows the finish to be applied very quickly and then have the rod moved to the 6 rpm constant speed dryer for final drying.

Good luck

I have a RW-XL3 wrapper with a finishing motor attached. I do have a 6 rpm drying motor which I do move rods to dry. Sometimes I want more speed. Never tried finishing in the 100 rpm range. My wrapping motor is variable, foot controled. The foot control is extremely sensitive.

Mark,
If you want to make the foot control less sensitive, simply install a lamp dimmer in series with the foot pedal.
These are the typical big box dimmers available at any of the home building stores for less than $10.

By adding the dimmer in series with the foot pedal, you will reduce the overall top speed of the wrapper, but you will reduce the sensitivity of the pedal in direct proportion to the amount that you advance the dimmer.

Take care
Roger

Roger, thanks for the comments!

Mark,
The sensitivity that you speak about is one of the main reasons that I have moved over to DC style gear motors to use as power wrapping motors.
The DC gear motors have an advantage of excellent torque, even with a low applied voltage as is the case when first applying voltage to the motor for excellent low speed operation.

Good luck
Roger
