Customized- Motorized Chinese Patcher

[GerryR]

Customized Chinese "Patcher" Leather Sewing Machine:

This is a Chinese Patcher that has been customized.  The frame on this unit is an aluminum alloy and not the typical rough cast iron frame.  It is precision cast and smooth.      Though the control arms are not "perfect" in appearance, they came chrome plated, which should resist rusting for the long term.  The presser foot tension control, the stitch length control and both thread tension controls now have custom made thumb nuts instead of the typical hex nuts, making adjustments a breeze.  The patcher uses the standard HAx1 home-style sewing machine needles of which there is a variety available for sewing leather.  The original bobbin winder was modified to run off the drive belt (see pictures).  Also, a spool holder has been added so larger cones of thread can be used.

I have added an Enduro speed control and motorized the patcher.  This unit runs on 220Vac, 60hz, 1ph.  (I was told that these units run fine on 120Vac, but at a slower speed.  I haven't tried it and would caution others about trying it.)  Everything is mounted to a base, which can be clamped to any bench or table (clamp provided), making it an extremely portable leather sewing machine.  The foot pedal is custom made to accept a cable-type control (think bicycle hand brake control) to activate the control unit.  Manual operation is still an option as there is a custom crank handle.

This machine will sew up to 5/16" (20 oz.) veg-tan leather.  I generally sew with size 92 thread on this type of machine.  You can sew with heavier thread, but the small bobbins limit the amount you can sew in one pass.  Size 138 is the max I have sewn with on a similar machine.  Please see pictures for more details.  Selling for $365.00, plus insured shipping, to the lower 48 states only.  It will ship in a box 36" x 18" x 16" and is appxox. 40 lbs.
