Hurbie Report post Posted October 30 (edited) Hello all , i found this forum looking for info to set up my "new" (close to 60 years old) Pfaff 145-6B H2L , i can't seem to find exactly what the letter combination means. i gues it's a H2 machine , for Leather , but what does the 6B mean ? after cleaning and oiling the machine , i used a u-tube video to set her up (from a german man, lot's of information in this) . lot's off fidling but for the moment she seems to run (and sew) very nice . am i correct that it uses the 134 style needle's , it had o longer needle in it , so adjusted it for the shorter needle . and another question , does anybody know the max stich length on this model , at the moment the max seems 5mm . thanks for your time Hurbie Edited October 30 by Hurbie Quote Share this post Link to post Share on other sites
fibersport Report post Posted October 30 Nice looking machine, easily will last another 60 years. There is another recent Pfaff thread, there are some great links to information on the Pfaff machines. Quote Share this post Link to post Share on other sites

Hurbie Report post Posted November 3 does anybody know if you can fit a bigger handwheel on this machine (to slow it down a bit ) and where to get one ? , i also planned to do a servo upgrade. Quote Share this post Link to post Share on other sites

If not add a speed reducer pulley as finding a larger hand-wheel probably is going to be difficult. kgg Quote Share this post Link to post Share on other sites

fibersport Report post Posted November 3 If you put a smaller pulley on the motor, I think 2" or 45mm is the smallest they make, it should slow it down just right. I also removed the brake shoes on my analog servo motor as well, made start up much predictable and smoother. Quote Share this post Link to post Share on other sites
