DIY Swirler Stein

The rc car arm makes it easy to make adjustments but, you can fab an arm.
You can run the wire outside for the pump. I would zip tie it to the down pipe and not bring it into the box though.
Some of the people wire the motor with solderless connectors, the type that are crimped on the wire. I will be soldering them on the connectors and then use heat shrink to cover the soldered area.
 
I ran my wires down the pipe and used solderless connectors. I like the connectors because it allows me to remove the MJ any time I need to.

I can understand your interest in not burning down your house. I was initially hesitant to cut my wires too. However, you're just cutting two wires and reconnecting them after threading the ends through the pipe. It's not like you need to run any 'new' wires. I'm glad I did it.
 
I am not so worried about removing the powerhead from the unit. The way I am going to attach the powerhead will require me to remove the whole thing anyway.
 
OK.
Again, pardon my ignorance here. For the wire from the motor, I imagine this is a wire with a plug on the end of it which you splice to the motor? Assuming that's correct, a plug has a larger and a smaller prong, each of which is connected to a wire inside the cord separated by a seam along the axis of the wire - does it matter which wire is connected to which part of the motor?
 
The larger blade is neutral and the smaller is live. On the motor it does not mater what wire goes to what connector.
 
Looks like the right motor.

Gear motors run hot. It's the way they are made. I can touch mine but not for long.
 
i seem to remember seeing something of this fashion that somebody made from one of those cheap clip-on desk fans....but can't for the life of me find it :mad2:
 
So these do run pretty hot then... But not hot enough to melt the plastic housing or to burn themselves out? I did not see any ventilation holes in the pics posted. I wonder about this since a microwave turntable would not be running 24/7/365.
 
I ran it open over night, and it did not seem that hot. I haven't finished my power head mount so they are no in use yet. They do have a bunch of torque. When I was experimenting I managed to break a the motor arm, it was to long.
 
These motors are actually designed for continuous use so they are fine to run 24/7. I ran a ventilation hole and piped in a small unused air pump because heat was a concern in the original thread and the success of an uncooled unit was in question. I don't believe it matters though. I couldn't tell a difference in the heat of the motor or the heat within the box either way (air pump on or off).
 
I ran both of my originals for ~30 months without problems (somewhere around month 20 I accidently dropped one in salt water and didn't notice it for ~30 minutes...good thing it was not plugged in at the time...and it still ran fine after giving it a few days to dry out). The heat really is a non-issue. Continuous use, same.
 
Those guys at HVAC Appliance Parts Supplies on Ebay are great. I notified them that one of my motors is making a grinding noise. I also told them that I glued an arm to the shaft of the motor, and am using them for something that they are not intended for . They said no problem and are sending me a new motor. How cool is that?
 
About this cool... :D
