looking at buying a 45k21

[LomaeArts]

I have opportunity to buy a Singer 45k21 biult in 1942.  The seller says it works well and has just been serviced.

The photos look good and the price is not unrealistic.  

I thought I would take some of my leather and sew 2 and 3 layers of 3mm combination chrome leather.

Is it posibble to detail what I should look for when inspecting the machine?

I'd like to announce I am now the proud owner of a 45k25. 

It was originally in a cobbler shop, before going to another leather working shop. It has been in storage collecting grime for a bit. 

The table was a custom job the also had a sole stitcher mounted on it. 

I am in the progress of fabricating a pedestal mount for it and add a servo motor. 

Photos to come.

She's a November 1950 model.  I came with the oil bath but I doubt I will fit it again.

Sorry i did not see your first post but looks like you done well with that purchase. Nice clean looking machine. so is it sewing well? I see you found out some parts were on the wrong way?? That will last you probably another 100yrs . Looks like your missing your bobbin winder or did you take it off also?

It came with a table mounted Winder. 

It sews really well. 

I am waiting for pulleys, flang bearings and new V belts to try it out properly. 

I am also waiting for more bobbin to be delivered.

I have an Adler 105, which is similar to your 45, I have a 50 mm pulley on the motor  put a new "M" belt on it, the pulleys are 3/8 not 1/2 inch like normal V Belts and now it stitches at my speed.

My servo mot0r spins at 3500 RPM, way to fast for my liking.  if I change the motor pulley for 65 to 50mm , I fear it will still be too fast.

Hopefuly if Aust Post does what they say they will, I will have a 5 stepped pulley and a new M V belt a day or two.  then I can play with hte final placementof the secondary shaft and the motor.

If you use the large pulley on the flywheel and a 50mm on the motor, you should have about 3:1 reduction. Add a 3:1 speed reducer and you should have about 9:1 overall reduction.

Which servo do you have? You should be able to change the parameters and reduce the top speed and the startup speed. I recently got my Pfaff 335 working again, I fitted the servo (cheap $100 unit off ebay) to the top of the table and replaced the handwheel with a large pulley, then reduced the top speed and startup speed parameters and it goes nice and slow now.
