Electronic foot control!
 

http://www.youtube.com/watch?v=C7bGt_BZk7Y I love it!

Now, I just have to research it out and decide what machine to modify.

My 328 K installed into a good table sounds like a very likely candidate to me. Just install the larger motor under the table and a belt like an industrial setup should work.

All gear drive, 15x1 needles, ZZ and cam stitches, drop dogs and that electronic controller with the high amperage motor sounds like the cats meow for everything from embroidery to upholstery....

do a video when you get it done!
