I just got a Pac Bay Wrapper with the good chuck. It sure would be nice to have a reverse switch...are there any kits that exsist already or are there any reasons for me not to rig my own?

I just turn it backwards by hand.

That's what I've been doing, but if I'm down towards the tip, it's a little tougher...I was just being lazy and thinking of adding a sw half way down.

When I`m near the tip take the belt off and do it all by hand.It is easier that way for me.

Contact PacBay directly. Aks for Bonnie and she'll direct you to the right person. They are great people and always willing to help.

There is one option if you decide to stay with AC 110v power.

You can obtain a motor - which brings the armature and brush windings to the outside of the motor. These will be 4 wires. then, depending on how you hook them up, you can reverse the direction of the motor.

For example:

[www.grainger.com] -- This is the style motor that is reversible.
I have used a 1/2 dozen of these motors to build power wrappers. I use the 300 rpm model. Then, I use 1:1 pulleys to drive a chuck, or I have used a chuck adapter to mount the chuck directly on the output shaft of the motor.

When I use this setup in a power wrapper, I use a double pole double pole switch to take the 4 motor wires, and reconfigure them at the flip of the switch to reverse motor direction.

I don't know if the replacement 5000 rpm motor would have the appropriate speed and mounting configuration for the pac bay wrapper.

--
Another option is to use a dc motor.
All of my current power wrappers use a 24 volt dc 300 rpm gear motor. I have built a 0-24 volt dc power supply - where the voltage is controlled by a foot pedal. Then, I use a one to one pulley setup to drive the lathe chuck. I then use a switch to reverse the polarity of the voltage to the motor and reverse the motor.

Thanks Fred...that's a definite DUH on my part...I guess it would make it easier to take the belt off and do it by hand.
And thank you Russ for that info...I will call them today...it seems everyone in this business is friendly and great to work with! I love it.
Extremely good information Roger...I can see you have already spent some time on this issue. I'm not looking to change my motor out, just wanted to see if the one Pac Bay uses is reversible. Your DC motor setup you have sounds perfect.
Thanks again!
Terry

I hope Bob Lee reads this, because we get asked about reverse all the time...

I do like Fred and drop the belt.

The four wires that Roger talks about feed the field coil & brushes. By reversing the polarity to either (switching polarity on one or the other, but not both) the motor will reverse direction. You've probably seen this done mechanically on an old school drill motor or electric impact wrench. On those older tools where you would rotate the cap or housing on the end of the motor 180 degrees to reverse the tool's direction, what's happening is you are rotating the brushes relationship to the field coil 180 degrees, changing the motors direction. This is more commonly done now days by simply reversing the polarity to one or the other (brushes or field) by means of a switch as Roger points out. It would mean removing the wires from the brush holders and extending them to feed the "line" side of a double pole (?) switch. The two outputs (four terminals) of the switch would then go back to the brush holders. One feeding +/-, the other feeding -/+.

Two problems doing it on the sewing machine motor on your wrapper. First, the wiring is all internal and there really isn't room to route four more wires into the motor safely. Second, it's liable to unscrew the chuck from the driveshaft under load.

Drop the belt. lol

On my wrapper from Pac Bay, if I turn the switch off from the dryer position, and then turn it back on, the rotation of the motor changes? I have not done any mods. to it.

The drier motor will do that. The wrapping will not.You can also stall the drying motor with your hand and it will switch.I do this to keep it rotating towards me so it dont loosen up.

Mark,
Right on.
I have pulled several sewing machine motors apart - as is commonly found on the pac bay wrapper, and did exactly what you described.

It is a bit of a tough go, and it takes great care to do the wire extension, and packing so that you don't have any shorts or problems with the motor.
However, if you take your time - have the skills and soldering iron to to the job correctly, nearly any motor can be modified as described above.

Take care
Roger

p.s.
Note:
This motor rotation is only true for brush type motors. It will not work for common single speed induction motors.
