Shopsmith Motor Project

[everettdavis]

Similar to the Bearing project, I have now begun a Shopsmith Motor Project.

I will be requesting input, photos and comments and managing it as we did the Bearing project

6 Nov 2017 I attached a pdf of how I am considering trying to present the various motors. This one is an A.O. Smith 1 1/8 HP one:

I have attached a work in process PDF to show you where I am taking this.

It is almost too large for the forum posting now as an attachment.

When it does become too large I will create a temporary Google Drive location for it and place a link to the most current file, removing the attachment here.

I just thought some folks might like a quick peek.

The Bearing Project was very interesting and quite helpful as have been the posts regarding Shopsmith Setscrews.

I have doubts about putting that much effort into a Shopsmith Motor Project. The vast majority (maybe all) of the Shopsmith motors have been treated as proprietary. That and the way they are built (physical configuration) makes them almost impossible to replace with anything other than another Shopsmith motor. The information required to do that is all available on the label of the motor being replaced.

About the only thing to learn is that not all Shopsmith motors have sealed bearings. Some actually have to be oiled.

I will be watching though and collecting information as this project develops. Who knows. I may be very surprised.

No matter what, you are to be commended Everett for your hard work and dedication to these projects. The entire Shopsmith community benefits.

That said, I really think you will enjoy where this goes.

Are you thinking about things like rewiring some of the shopsmith motors to run forward and reverse? I'd like to do that and while there are threads here on the subject perhaps some new information and or photo's could be taken if it would make the process more clear.

I have a headstock that I got that has the A O Smith motor (not verified yet but I was told it does). And after having the powerpro I really find a lot of uses for the reverse and wouldn't mind having my shorty be reversible, well I could get a third powerpro but this might be a cheaper path.

I am not that expert, sadly our late friend Bill Mayo was, and there is an excellent thread as you mentioned where others have done some of the motors.

Take the Franklin original motor for starters: where the Motor Sheave spring was retained by a washer and a (left hand thread) nut, which was kept tightened by the rotation of the motor.... reverse the motor and it has the potential to spin off and release the spring on the motor, as well as other undesirable things on selected shaper and router components on the output quill / accessory side.

I am open to what we include in the Appendices and that well could fit in with others contributing to it... disclaimers etc for do at your own risk.

I am starting with the Franklin Electric 3/4 in the original Mark 5. John Burger is considering working on the 10E and 10ER motors.

Here is where I am beginning....

Next came a A.O. Smith still with the left hand thread retaining nut on the Motor Sheave spring.

I must have been dead wrong when I said I would have doubts regarding the usefulness of what this project creates.

I am not particularly interested in rewiring motors or even replacing bearings/bushings but understanding the configurations of the various applications is of interest.

For example: We frequently speak of some motors being reversible while others are not. While the motors in my Mark V are not reversible, the motors in my Crafters Station and Power Station are.

Some motors are sealed and require no periodic lubrication while others have oil cups and need to be serviced. The Crafters Station and Power Staion have motors that need to be oiled periodically.

I am also curious as to why Shopsmith (maybe Emerson) decided to bearing the one motor winding so deep that it cannot be extracted. If it could be, that motor would likely be reversible too. We'll probably not answer that question and I'll remain curious forever.

This forum has already taught me that some data (motor specifications) is available for research even though I was unable to find it via an online search. http://www.shopsmith.com/ss_forum/woodw ... ml#p240865

Two functionally equal motors of different vintage. My Crafters Station and Power Station. These motors have 5/8" shafts.

I just posted a pdf on the first page to give you an idea of how I am progressing and where I am taking this.

It is almost too large for the forum posting now, so I will move it to a temporary Google Drive as we work together to flesh this out.

I hope you find it of benefit. I hope I have it finished by Christmas, but I will keep it updated and put a date by it for the last revision.

I have encountered two separate versions of a 1.125 HP (1 1/8 HP) A.O. Smith motors that are in different housings and have different labels.

I do not have disassembled photos of both motors to prove or disprove they are mechanically the same inside, have the same centrifugal switches etc.

I presume the C48L2A1 is the earliest version and the C48L2A16 is the latter. I am curious if there were a A11, A12, A13, or A14 versions released through the years.

I am trying to do due diligence to the Motor Guide I am working on and need to know what others have observed relative to this and other variants through the years. Not only on A.O. Smith but all the brands we know have been used.

Any information, especially photos of motor tags would be helpful.

See attached.

I so miss my late friend Bill Mayo. He would have so much to contribute.
