Thank you Dwight. I was introduced to leatherwork in Turkey. After that everything was/is self teaching...

My sewing machine is an old Juki DNU 241H. I recently bought it and I could only found over internet a manual which is not very detailed. It states that it can sew with maximum 24 size needle and the standard would be size 23. Size 23 needle was just good for thread size 10/3 but you could see my corners... and adjusting the tension was a headache. On the same seam there are stitched where it seems like the bobbin thread is tight/top thread is too loose THEN there are some stiches ok, and there are some stiches which looks the opposite way (boobin thread loose or top thread too tight). I can't understand why on the same seam the tension varries .

Thank you for the advice. I will trythat, I also start to believe my machine can't handle the thickness of the thread..

Yes, I leave the needle in the leather.

when I reach the corner point, I lift the presser foot, turn the leather to 90 degree, drop the presser foot then continue sewing. But my corners look awful. What I am doing wrong ? Please help.

Thank you CowboyBob and Random. The guy who is selling it (new and used sewing machine dealer) doesn't recommend changing the motor. He says the motor is an old Italian brand and even it is an old one, it is better than new motors and he can make some changes to it (I am not technical at all...my appologize) to reduce the speed. I want to use the machine to sew wallets (goat skin), and bags. For bags I use vegetable tanned leather.

Will this machine sew 2 layers (and maximum would be 3 layers) of 5 oz leather? Thank you.

Thank you so much for your answer.

I am thinking of purchasing this machine (second hand, obviously...). I would like to know what is the maximum thickness for thread this machine can sew with? Can it sew with z277? Thank you.

I thought that I PM you, but I think I sent a message to myself:) I am not very familiar with LW forum. There is no loop anymore, that spring adjustment solved the problem. Now the handle moves a bit hard, sometimes the foot get stuck "in the air" and same time I cannot move the handle, then I push a bit the bobbin shuttle and/or force the needle to go down just to force same time the foot to go down. I think I will try tomorrow, I tried enough for today... Thank you trekster for your patience and all your help.

I hope this is not going to happen to me/my machine. It's not easy to get Tippmann Boss spare parts here in Europe. Before I purchased the Boss, I was thinking of Sailrite Ultrafeed. Now I see that spare parts /components are very easy to find for Sailrite. Boss uses very long needles that I need to purchase on internet.

When I lower the handle, also the Arm-Bracket Thread Take-Up CAR-11 is moving down and then the take-up lever has no support and that's why is moving down...

Yes, the take-up lever moved down almost 1 inch.

I tried that but the take-up lever won't move. I discovered another solution: I squeezed a small piece of sponge in the thread guide H. It works until the small piece of sponge falls down, the re-place again the sponge.... trekster, thank you very much for your assistance. I can not say enough how much I appreciate it. I saw a post with a problem that looks same : http://leatherworker...showtopic=38480 but I checked my machine and I have AR-49 spring...
