This would be considered a peak and freak. Freak out at all the work.Close it up and say "I'm sorry, it just is not worth fixing. Maybe you should buy a new machine."
But new machines like 1951 vintage 301a Long Beds are not to be had, just like that. But there were a lot of them made and I am sure that there are many in much better shape than Sal.
God knows I am not trying to make a living from this avocation. I have HOURS and HOURS of labor in this clean up. No one can afford this machine now. Were I a professional, I would have shunned this project, most certainly. So I am glad I am not a professional. I feel quite proud of this accomplishment.
I also wonder what a professional would think, should he or she read this blog and learn of my stupidity. See this screw? I tried for thirty minutes to put a DIFFERENT screw in the hole that holds on the tension release lever. Thirty stupid minutes. Finally, I decided to try this screw. It worked in about 30 seconds. DUMB.
Or how about putting the looper on the hook backwards?
I put the clean parts back together, backwards, and wondered why the needle bent and pinged as it went through the cycle. I finally decided to check the photos I had taken. DUH. Once I turned it around, smooth as silk.
Will I remember for the next time? I don't know. I will, however, remember to keep the computer with the photos close at hand.
What would an OSMG do about this old motor? Probably do what I did, take the armature out and
clean the commutator and most likely replace the brushes.
I don't have new brushes so I checked them and cleaned the brush tubes. I put the motor was back together in fifteen minutes, this time. On Sunday it took me thirty. I wasted time by taking it ALL the way apart. Not necessary. Practice makes perfect; or close, anyway.
The electrical was a bit scary so I used another set up from a different machine to test it. I then decided that I wanted to re-wire it. I spent another 15 minutes trying to find its power cord and foot controller. Finally found it, in the last place I looked, in a drawer in a sewing machine cabinet in the shop. Geez. I have to write this stuff down.
It always amazes me that these old machines stitch after all that. The stitches are good. The tension needed tweaking, but NOT THE BOTTOM. I am just amazed.
Would I take on a project like this again? Hard to predict. Perhaps if it is a five dollar machine. I paid much more than that for Sal. I committed to the sale without looking at the machine. I am not sorry, not in the least. But I don't have to make a living doing this. And that, is a good thing.
