DKeuhn - I'll have to figure out how to post a picture when I am done. THANK YOU pictures always help! I will go ahead with the Vaseline and I'm still waiting for the Tri Flow. I'll use another machines foot pedal for a test. A lead pipe - hmmm it is flakey I will take another look, I thought it was a wrapped wire......
Livesimplemama - I am going to guess you already removed the sewing table portion of the base? There are 4 screws if you haven't taken it off yet. It slides right off. I did not take my light entirely off.
