Betsy yelled at me Thursday night as we were leaving work.
"What are you doing, working with acetone in a non ventilated room?"
"Ummmm, geeee, Ummmm."
"And with a cough and a cold, no less. You KNOW better."
And she is right. I do know better. But really, I wasn't working with A LOT of acetone. And the container was all sealed up tight.
So today, when I went out to work with the ATFacetone mix, I opened the window. That should keep her happy.
I don't know that the miracle mix was all that spectacular. I put the lifter roller in the vice and blew the hair dryer straight onto it (as they say here in Otsego County) for five minutes. I also had the little heater warming my feet, until the circuit breaker flipped and I had to choose between the two. (Me and Carole King). I chose the hair dryer because I really really wanted to get that OTHER 201 back together. I am about 201d out. The roller was still stuck. No magic here. I dribbled some Tri flow and applied heat some more.
I set to work cleaning other parts as I heated the lifter roller. The bobbin case retaining ring was pretty gooey. I used Krud Kutter on it and rinsed with denatured alcohol.
Hmmmm, I wonder if Krud Kutter would work on the lifter roller? Worth a try, nothing else has seemed to work.
I dribbled some Krud Kutter on it and heated it up some more and then grabbed the plyers. I know that this was risky. I could really bugger up the roller with those metal teeth. But, something gave, every so slightly. And I just kept turning and turning and wiping Krud off the edge of the roller and finally I could turn it with my fingers. I rinsed everything in denatrued alcohol and applied copious amounts of Tri Flow. I kept turning the rollers until the exudate from around the roller was clear. Nice and smooth now. And reinstalled.
Honestly, it likely was a combination of all the solvents and the heat, rather than just one thing that got that roller rolling.
The machine sews nicely. I don't think there is any difference in speed. But at least I know that no one would be wearing a flat spot on the roller when the machine is in use. Plus, now I know how to adjust feed dog height on a 201-2. Might be useful to know.
