Members depodarcom Posted July 4 Members Report Posted July 4 I have complated my singer 45k25 table project by cutting old fur sewing machine table. I attached the main body but how can I activate foot lifter .I couldnit find any clue from old writings.For new machines it is called as knee lifter I guess. What should I do for activating my machine chain shaped foot lifter? Quote
Contributing Member friquant Posted July 4 Contributing Member Report Posted July 4 (edited) Beautiful table! A foot lift is activated by pressing down with your foot, a knee lift is activated by pressing to the right with your right knee. My Jiang Long came with both, but I had to ask how to install the knee lift. Here is the install video they sent me...the chain actuator reminded me of your singer. 937adbfd78d59f2d56efebcd9d6f1892.mp4 Edited July 4 by friquant Quote friquant. Like a frequent, piquant flyer.

Members SARK9 Posted July 4 Members Report Posted July 4 The simplest way would be by attaching the chain to a foot pedal, but you would probably have some real estate conflicts putting that on a treadle base. Next would be adapting a knee lift pad similar to the typical ones used on machines like the Consew 206 and several others. There are a few different styles sold as aftermarket kits and you could work out the geometry to suit. A small air cylinder is also an option (I have several on various machines) but they are generally all the way up or all the way down NOW as in "ON/OFF" unless you go full MacGyver on the attachments. The knee lift kits are probably the best bet and can be as cheap or dear as you like. -DC Quote Machines: Juki LU-563, Consew 206-RB5, Singer 20U33, Pfaff 481, Mitsubishi CU-865-22, Consew 29B, Rebadged Juki LU-562, Mitsubishi LS2-180, Seiko SK-6, Juki LG-158-1

I am also searching for "stirrup" that is used for horse riding.. Quote
AlZilla Posted July 4 Report Posted July 4 Unless you're going to sit at that machine, I think a knee lift is out. I have a broken bass drum pedal I'm in the process of adapting to operate the servo motor on a sewing machine. The "beater" is broken off, so I'm just going to attach the pedal frame to the table legs and attach the servo motor arm to the pedal. Maybe this pic will inspire something. Edit: I just saw your stirrup idea. That might work, too, if you could keep it from swinging all over the place. Maybe a chain guide of some kind down low, limiting it's swing. Great idea.

Just a nothing special bog standard servo from ebay: https://www.ebay.com/itm/356814829633 It says it's 750 watts but I bet when it gets here it's 550. It's got a 2 to 6 speed reducer already.

I thought you were going to use the kick drum lever to tell a separate servo to raise the presser foot. Quote friquant. Like a frequent, piquant flyer.

I'm suggesting he could engineer a pedal similar to what I'm doing to pull down the lever to control the servo motor on my project.

These types of stands had knee lifters, but since you don't have one a pedal attached to a tube around the tramp shaft would do the job.
