Members PappyUSA Posted May 10, 2013 Members Report Posted May 10, 2013 Thanks PappyUSA. Were you using a 250 needle? Sorry I can't remember, I gave the machine to my son so it's not here for me to look at. The way I picked the size was by whatching the needle slide down a 346 thread at about 45 degrees. 346 is all I used to work with. That Boss is an excelent maching for sewing horsehide holsters. Jumping off point for bobbin tension is about 16 .oz of pull and then fine tune from there. Trigger pull scale is what I used to use to measure it. After you get used to it you'll find the Boss to be a perfect holster machine. Quote
Members RoosterShooter Posted May 11, 2013 Author Members Report Posted May 11, 2013 (edited) Thanks PappyUSA. I never thought to use my trigger pull scale! That's a good tip. Chavez .... Follow the instructions of the manual plus a few steps. 1) Loop the thread around the Secondary Tensioner as you do on the Primary Tensioner. 2) Start turning BOTH of the tensioner wheels down 1/2 turn and the bobbin tension 1 full turn each test. 3) After you get a perfect stitch line using your settings ..... do one more 1/4 turn on both Tensioner Wheels & 1/2 turn on the bobbin, for good measure, and lock it down. .
