Glenn: Thank you very much for your help. The machine is getting closer and closer to working for me. Using a smaller needle and having a deeper slot on the throat plate has done a lot. Now I'm just working on reducing the speed, and will hopefully be able to get a "standard" speed reducer somewhere, otherwise I need to build one. Murray

Thanks Glenn. What I'm hearing is that it is possible to get this machine to work. How do I time the bobbin case opener? I know that it is adjusted by the screw at the 4 o'clock position relative to the bobbin, but I don't know when it should be "opening". I will open up the throat plate slot and see how that works.

Thanks Chris We're using a 134-35 size 24 needle. We started trying to sew with 277 thread, then 207, then 138. The 138 worked best, but still had jams. Perhaps I need to put in a smaller needle with the 138?

Hi There I need to see if I'm trying to do the impossible, and could use some help. My wife's 145 H3 is has a BSN configuration: medium weight fabric materials. I would like to sew heavy leather (5-6 oz) on it using #207 thread, and it's not going well. The machine will pierce the leather reasonably well (especially after I've added a servo motor), but the machine won't pull the top thread up consistently. I've played with the tensions to no avail. It will work for a few stitches, but eventually a loop will stay under the feed dog and jam. I've had to re-time it a dozen times as it will just slip the . I'm thinking the thread is too large to fit in the space between the needle plate and the rotary hook "keeper" that goes into the slot on the plate. Now, looking at the parts manual, I can see there are differences between the fabric and leather models beyond torque, so perhaps I'm trying to fit a square peg in a round hole. I know the rotary hook is different and, the flywheel too. Any suggestions? Can I make this machine work as is? Should I find the parts to convert it to a leather machine? Or just sell this machine as is and start again? Thanks Murray
