Someone in the Juki 98 yahoo group suggested that I put shelf liner under it as well. I had to raise up the machine a bit anyway since it was about 1/4" too low.. it helped a lot.. so I put several layers under it and then realized that the back needed more than the front. I think the machine isn't quite level! That might be a part of it..
So then I looked around my room and saw the Janome under machine mat that I got when I bought my Janome years ago. That helped A LOT. It doesn't shake nearly as much as it did before.
I then took it out and put it on the desk that I used to sew on (we couldn't use that one because we felt the drawer wasn't as sturdy as the one we cut up. wow. Never noticed just how much my machine liked to jump before. There is a certain mid range speed that I sew at that makes it dance. That Janome mat might just be what I need to fix the issue at least to the point that I can actually use the machine.
I'm really happy - or at least much happier than I was when I went to bed last night.
I think the next time my father in law comes up we'll try a few more things. We still need to cut the plexiglass that I need to the left of the machine for accessing the bobbin. I might take my machine down to the glass cutter store and have them cut me a piece to form fit to the machine. That would be sweet
