Members CustomDoug Posted August 21, 2011 Members Report Posted August 21, 2011 Has anyone used a modern servo motor on a typical vintage Singer 29K table base (bi-level)? Actually mine's a long arm 29K62 but I doubt that'd make any difference. What alterations to the table, base and/or motor would need to be made - if possible at all. Would there need to be some sort of offset brackets made up? Anyone got pics? Quote Does Anyone Know Where the Love of God Goes When the Waves Turn Minutes to Hours?
Moderator Wizcrafts Posted August 21, 2011 Moderator Report Posted August 21, 2011 In order for you to mount a servo motor on that machine you will need cut out the space between the existing belt holes (unless you assemble the belt with a c-clip), and drill some mounting holes in the iron base and maybe even add a wooden platform for the motor to bolt onto. I found a cheaper and easier solution for my long arm patcher, with parts I bought from Toledo Industrial Sewing Machines (866-362-7397). See the photo below. The kit came with a 21 inch ribbed vinyl belt which was too short for this particular machine. That's why I used a thin leather belt. It works okay after I sprayed it with belt no slip spray. Total investment was about $100 and an hour of my time figuring out where to drill and tap the hole. The 5/16" x 18 screw was included. I have my own 1/4" drill and 5/16x18 tap. If your machine is flat across the back, you can mount the motor with the bracket facing down and use the 21 inch vinyl belt, which gives much better grip.

Moderator Wizcrafts Posted August 21, 2011 Moderator Report Posted August 21, 2011 Here is a picture of the same size motor, ready to be installed on a flat back patcher, in such a position as to be able to use a 21" home style no slip ribbed belt...

Members CustomDoug Posted August 21, 2011 Author Members Report Posted August 21, 2011 Wiz awesome of you to post the pics but I honestly can't completely make out what's going on - the pics are too big, could you resize them by chance? Also, is that appx. $100 besides the cost of the servo motor (you said total but I'm confused)? Quote Does Anyone Know Where the Love of God Goes When the Waves Turn Minutes to Hours?
Members amuckart Posted August 21, 2011 Members Report Posted August 21, 2011 When I saw this I thought about how I'd do it, and figured as I'd pull the patcher off the stand, install a plate between the patcher and the stand sticking out the back and bolt the motor to that. From there you could rig an extension from the pittman of the stand's existing pedal to the motor control, and it's all totally reversible if you ever want to take the motor off again. You'd need to be a bit careful about the size of motor you chose though, a full-size industrial job might be too heavy, but from the looks of the ones Wiz posted pics of you don't need a big motor to drive a patcher.

Members wolfe9 Posted August 21, 2011 Members Report Posted August 21, 2011 What Wiz used on that one was a small can motor like what was on home or light duty machines (not a servo ) Like amuckart said , I always try to do things that are reversible if possible just incase I want to sell it in the future.

Moderator Wizcrafts Posted August 21, 2011 Moderator Report Posted August 21, 2011 The motor I used is an AlphaSew 150 watt home motor. This is the most powerful motor of this type. It has a solid state foot control pedal. The only problem I have is a bit of slippage of the leather belt, until the wheel gets into motion. I am searching for a longer rubber or vinyl belt, which won't slip much at all. Once the AlphaSew motor starts the machine sewing, it keeps going until I stop it. The reduction factor is really high, going from the tiny pulley on the motor to the large pulley on the machine. The price I mentioned was everything, including the thin leather belt and C clip. But, I already had a tap to thread the hole for the bolt. The machine can still be operated by the hand wheel, even with the belt attached.

Members CustomDoug Posted August 21, 2011 Author Members Report Posted August 21, 2011 Wizcrafts the pictures are so big I can not tell about the size of the pulley on your machine.... since your handwheel is on the front - is the pulley (that the leather belt's attached to) the same size as the stock hand wheel pulley? Quote Does Anyone Know Where the Love of God Goes When the Waves Turn Minutes to Hours?
Members CustomDoug Posted August 21, 2011 Author Members Report Posted August 21, 2011 ..um nevermind, I think I see that it is actually the stock pulley after all - handwheel is seperated and moved to the front by itself (duh ).

Members CustomDoug Posted August 21, 2011 Author Members Report Posted August 21, 2011 I think I'll give Bob a shout and try to source some of this stuff - thanks ! Quote Does Anyone Know Where the Love of God Goes When the Waves Turn Minutes to Hours?
