I think what worked was loosening the two large screws which let me change the bottom arm which restored the timing. It still wasn’t catching the bobbin but I think I was too rough putting it in and a small metal plate got bent a bit. I noticed in your video the bobbin dropped in easily. So I adjusted that. I also added a lot of oil. One of the places where the thread goes through two small plates was tight. I noticed it went up and down with turning the handle but not much. After I oiled it, it went up more and loosened the plates. I think the thread was getting stuck there. It misses a stitch on occasion. I am not sure how to adjust the cam for the thread lever or if that would help. On the front of the machine is a small screw but they are stuck and won’t adjust. I added some oil so maybe. Right now I don’t mind an occasional missed stitch. Thanks so much everyone for the help! I will get the thread changed to smaller and I am also going to buy a lot of needles at once! Cindy

I got it working! Thanks so much for your expertise! I didn't make the best decision on getting this machine. I knew I wanted a patcher/hand crank and this one was for sale on Kijiji. I am a Hand Therapist and definitely no expert in sewing leather or machine repair. So I am very grateful for the assistance! I did break the needle. I had gone to a sewing store and they gave me 332 needles which I saw in a post from Constabulary that the 332 long or 88 would work. The ones I got don't work they are too short. Can you tell me if they are the long? From previous posts it sounds like needles are hard to find, the machine has 657 needle as the recommended. Any suggestions on where I can go to purchase some? Thanks

Is this the cam track? It looks like I should be able to just pull it towards me but its not budging. It doesn't look like there is anything to unscrew. Do you think the circle has anything to do with getting it off? Thanks for your help. It is greatly appreaciated! Cindy

Thanks for the advice. I did hold the thread snug this time and the thread catches but does not go around the bobbin. I also think there is a timing issue. I have minimal experience with sewing machines do you think it needs a professional or is it relatively easy to get the timing in sync. I watched Constabulary's video several times and noticed the hook is at the needle when the needle is down. With my machine it seems to be back at the bobbin when the needle is down.

I recently purchased this machine to sew leather wrist braces/splints. When I went to pick it up it was working well. I transported it in the back of my SUV about 4 hours and we were careful loading it. When I got it home I purchased thread Nylon 70. Watched the videos on this website for threading and winding the bobbin. Now it is not working, and I am not sure why. If anyone has suggestions on what I could try I would be grateful. Thanks Cindy
