Art, Thank You for your reply.My name is Robin.I have been a Thoroughbred Horseman for 38 years.I have rode all of those years and still get on horses every day.I am in the "Tack" repair business out of necessity.There was no one around to repair wore out boots and chaps,at least no one that didn't sew with anything better than a nail and binder twine.I also have worked in the Jockeys Room for many years which brought a whole new batch of repairs(race saddles,light boots and girthes) I started repairing chaps and such with an old donated Singer table top machine.I then bought a knockoff Juki garment machine,which was not much better than the wore out Singer.A few years back I purchased a new Adler 267/373.This Adler does a nice job(of light work).The repairs I do in the Jockeys Room needed a special sewing machine ,I ended up with an Adler 30/10 Boot Patcher.I have been patching boots for a while now. A lot of the work that has been asked of me(exercise saddles,halters and race tack) is to heavy for either of these machines,so last summer I purchased the Artisan Toro 3000 that is why I asked about a Juki 441 (should have bought the 4000 for the added inches 16" throat over 9)I have never sewn with a machine of this caliber.I have been stumbling through repairs sewing a finger to my work every now and again.I just ordered the book you mentioned(Robert Stienke's Bridlework) on line for $50.I seem to have a problem sewing close to large buckles.I hope the book will answer a few questions.Again thanks for the help.
