PM 727 Z Axis Power Feed

Have you seen this thread? http://www.hobby-machinist.com/threads/pm-727m-powered-z-axis.45294/

To use a power feed like on the PM-833 you would first have to determine if the stub shaft for the crank on the PM-727 is long enough and has a diameter that can adapt the power unit and bevel gear and you would need to come up with a way to bolt the power feed to the mill. This manual shows how they typically install. http://www.shars.com/media/manuals/user_manual_XYZ_shars.pdf

The PM-932 & PM-940 use a gear motor coupled directly to the Z axis lead screw on the top of the column.

I re-purposed the gear motor off my PM-932 to raise and lower the table on my heavy duty drill press. http://www.hobby-machinist.com/threads/something-a-little-different.55567/#post-463941

Any of these methods will require some modification and fabrication of parts.
 
Thanks Jbolt. I would prefer the motor that you shared the link in the Shars. I have seed the other link, but I am not electrically inclined in the least. I would think it would be easier to use the power feed from share. Think I will reach out to matt.

I completely understand the electrical part. I'm the same way but I get stubborn and grind my through. The amazing help available help on this forum makes some projects possible that I would not have ever attempted on my own.

You can do better on pricing on the power feeds if you shop around you just need to know which model will be adaptable.

Definitely run it by Matt. You never know what he has in the works.
 
Jbolt- Just communicated with Matt and he had a good point...the one on the 932 is 220V. I am going to shop around as the z axis on Shars is looking good. Need to see if it is 220 or 110.
 
Hey buddy, are you wanting to power the quill or the entire head assembly?

Hey Lee- I want to power the entire head. Thanks for reaching out. Let me know if you have any thoughts. I know you did your 727 but not sure I am equipped to do the setup you had?
 
I went through several iterations before I finally found a solution I am happy with. I'll put together some info and forward it to you.

Thanks Lee. That would be great. I am starting to get tired of cranking that handle:)
 
I know exactly ly what you mean.
