Well on July 2nd our restoration team has almost completed another mining equipment project.

A 1920's Jeffrey model 35 B shortwall cutting machine.
This machine was last used in the eastern Ohio Bituminous coal fields.

This was the most dangerous piece of equipment to operate in a deep mine. More people were killed either by operating or by the coal dust caused by the cutting action of the teeth latter causing "BLACK LUNG".

This machine quickly gots its name as the:

"WIDOW MAKER"

35 hp
6ft cutting bar
250 Volts DC
Built by Jeffrey in Columbus, Ohio

This piece of equipment when aquired has not operated in over 60+ yrs.

Basically everything was locked up & seized so bad that it made this project challenging. Our team had to disassemble the gearbox by 70% just to remove the cutting bar to brake the chain loose. Finally after getting covered in grease & coal dust we began to reassemble. Our first test trial of operating the cutter at full voltage was completed successfully on July 2nd.

ah yes, although youre late. mike already sent me a video on my phone a few days ago when you first sparked it up. also, you forgot to mention the rectifiers you blew up getting it to run. from what i hear that was quite spectacular! :lol: almost as spectacular as when i once turned out mine motor into a welder.
