Lol, I bet I'm older than you think I am.Not bad Dan, for a young guy (sorry...I couldn't resist)
I am surprised that you didn't put machine leveling feet on the base though. It would have helped with that uneven stance/vibrating.
I don't know how tall you are, but that machine is sitting way too close to the ground for me. My table sits at ~44" off the ground and well above my waist when I'm in front of it. But then I'm 6'3" and too old to stoop for very long. I'm sure you'll do fine.
