Cumberland Highpower Report post Posted April 15 (edited) They're excellent machines. My parents bought one at an auction 30 years ago for $125 and it was a real tank. They still use it for occasional projects. Easy to use, well made, precise. Only downside was the standard bobbin, but that's really a minor thing in this era. Make sure you have the smallest pulley on your motor. Also, I don't know the speed rating of your motor, 3450 vs 1725. They're all roughly interchangeable on the table. Needles should be 135x17 if I remember right. Yes of course it's good for leather and anything you can fit under the foot. Use 135x16 needles on leather. Size depends on thread you want to use, you can look online and find some data. 138 is the max thread. Edited April 15 by Cumberland Highpower Quote Share this post Link to post Share on other sites

fibersport Report post Posted April 16 Not to disagree with your findings but a Pfaff 145 H3 would normally use a 134-35 needle system. Now, they can be adjusted to run the more common 135x16 or 135x17, just make sure that you're running the correct needle. The Pfaff's are a great machine, I had a 145 and was able to find a 545 which I have now. I installed an analog servo motor with a 45mm pulley, I can run a stitch at a time for great control.

This evening the seller comes at my house to install a servo motor because for my projects this beauty runs too fast !! haha So it s important a pully of 45mm ? Yesterday it was the BIG cleaning up side down !! haha Quote Share this post Link to post Share on other sites
fibersport Report post Posted April 16 While you can use both needle systems, you might run into some problems if the machine is not adjusted correctly. It sounds like yours was set for the 135x16 or 135x17 so as long as it all works, go ahead with using them. The 45mm pulley on the motor will give you the slowest starting speed to make it easier to control the machine. A larger pulley on the motor will produce a faster starting speed on the machine. To slow it down any more will require a speed reducer but that's getting a little complicated for now, enjoy the machine with the servo motor with the smaller pulley if the previous owner installs one.
