We still need to cut and add the plexiglass to the left of the machine. I think this will work. I might look for a floor mat that is a little lower than the Janome mat so that the machine would be completely flush with the desk top but for now I'm just happy that it isn't making me dizzy from the bouncing when running the machine.
I have built many a cabinet and desk for myself, for many different reasons. And judging by your pictures here, my best guess for most of your problem is going to be in the shelf support system you have going on. The metal brackets that once supported the drawer is NOT strong enough to support your machine for any length of time nor will it help stop the extra vibration when the machine is running. I'm not saying this can't be fixed, I just want you to understand why it is giving you so much problem. The added padding you put in will help for a while but in the long run, one day it's going to give in and I hope you are not using it when it does because you will get hurt.
With all that said, maybe I can help a bit in suggesting a better support system that will last longer and maybe forever if you can add it. The first thing I see is that the self you have in there is NOT going all the way across to the sides, it looks like it's just hang in mid air. This would seem like it's only support is on the brackets. I can't see the type of brackets so I can't help with that but you mentioned that they are to hard to remove so what I would do is get another piece of 3/4" thick plywood and cut it to go under what you have but extent it all the way across the bottom. Screw it in place so it is well supported by the whole frame of the table. If that doesn't fix most of the vibration and keep you safe I don't know what will. You guys are on the right track but it's a matter of corrected support for the machinery going on here.
I hope you take this as helpful and not just trying to be picking or something because it's meant to be as helpful as I can without coming over and fixing it for you. You really do have a great idea here so don't scrap it. You will get it done and be a very happy camper not spending tons of money.
