Singer 211u867 has air cylinders for lift, reverse, tension release, and thread cutter

I bought two of these machines but they don't have any solenoid or control panel to operate these features. What do I need to make these work?

Efka DC1550AB321 (Only in 220V single phase) or Mitsubishi XLG-554-10Y.  Solenoids for air are going to be required as well.  This sewing machine setup is not for the faint of heart, and requires extensive setup to get this project up and running.

Thanks I have been in industrial maintenance for 30 years. I can do the work to set it up.I just never have seen this type of setup.I would need air solenoid and switches to operate them. Would I need momentary switches or switches that have different positions? I could maybe come up with some 120c 

 and just wire some switches in to control them.

I agree with Gregg that timing is very important, but relative timing, not absolute. Unless you are setting up for high-performance production, you can rig something up.

Have a look at Automation Direct web site, they have everything imaginable for this sort of work.

Thanks!

Most of the servo motors with control boxes fire off 24VDC signals for things like presser foot lift, back tack, among other things.
