new member with a Pfaff 145

[Hurbie]

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

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.

i tried reading every thread regarding the 145 , so far no luck in finding what 6B means .

1 means flat bed machine

4 means horizontally placed hook

5 means single needle + walking foot

subclass 6 = for general work

B I am not sure, B as standalone means needle, hook, feed an plate for light fabric (A = thin, B = light, C = medium, D = Heavy), but you have 6B and not 6-B

H = high throw

L  = leather

they can have different needle systems, according to subclass

that is a very informative piece , thanks for that !

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.

Changing to servo motor may give you enough slow sewing control. If not add a speed reducer pulley as finding a larger hand-wheel probably is going to be difficult.

ok , i'll wait for the motor to arrive and see how that goes .

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.

B is the sub class.  goes to C, C/D the D for heaviest.  6 is the max. stitch length.
