By ten this morning I had all the parts back in the 201-2 motor and was ready to attach it to the machine. I still had to make the connectors and since I cannot crimp I decided to make my own out of the ends of the wire. More soldering. I had not measured the motor lead wires so I had to figure out how long to make them. I pulled the motor from the miscreant 201 and used them as the template.
I had bragged somewhere, maybe here, that I can pull a motor from a 201 in five minutes. I was guessing. I have never timed myself. Today I did. Three minutes. Really. From start to finish including re-attaching the terminal screw. Of course, the motor has been off and on that machine many times in the past year. Pulling the motor off of a 61 year old machine that hasn't been serviced in YEARS is another story.
So I got the motor and the machine running. It is always a relief when everything works. I decided that was enough. Yeah right.
I noticed that the tension release pin was not releasing the tension as it should. More time and frustration dealing with that. I had not wanted to take the presser bar off. But it was so dirty and I had to figure out what was going on with the presser bar lifter. I got everything clean and shiny and re set the presser bar height at "no more than 19/64ths of an inch above the needle plate..." Really? How the heck do you measure 19/64s?
Well 19/64ths is a bit more than a fourth. (3/64ths to be precise). I borrowed an idea from Rain and measured the height of some playing cards. When I got to 1/4 I added a couple more cards and called it good. I bound them all together and use them under the presser foot when I am adjusting the presser bar height. Works fine.
Finally, after dinner, I tested the stitch on the Pittsburgh 201. I was pretty surprised to see that it made a nearly perfect stitch right off the bat. I had taken the tension adjusting spring COMPLETELY off of the bobbin case when I was cleaning it. I tightened it back down all the way when I re-installed it and then backed it off a bit. Nothing scientific there. I set the top tension at 4 and it was just a bit tight. Then I gave it all out power and it was just as slow as the miscreant. I was BUMMED. But as I held the controller down it started to speed up. After a bit it was going fast enough. I started sewing with it and just made row after row of stitches. Then it made a clunk and slowed right down. To almost nothing. CRAP. I took the hand wheel off and looked at the worm. It was fine. Nicely lubricated. I put it back together and tried the motor with no load. It was ok. Then I put it out of bobbin winder mode and it was still ok. Then I gave it full power for about three minutes and it kept gaining speed and gaining speed until it was hauling you know what. And then I stitched with it. At top speed. And it stitches beautifully.
I tired some really tiny stitches. I tried some regular stitches. I am not unhappy.
Now I have to figure out what the devil is wrong with the other 201. But I am sewing tomorrow. Promise.
