Damn, I'm just catching this thread for the first time, and jeez, I feel for you Bub. What a kick to the stomach. I have a buddy who swore by his cheapo Harbor Freight lift, until his toppled, so I was shocked to heard yours was a Handy.
I've got the SAM 2, with the side extensions and the leg stablizers, and I'm going to go and inspect this now. Whenever I've ever moved it around, I always had the table fully risen, and I moved it around like a wheel barrel from the rear. The wheels are in the front, so it just never would have registered to move it around from the front. However, in your scenario, I can see exactly what you're talking about so thank you for the heads up. I too will be figuring out the bast way to add a carrage bolt and nut in a manner that it doesn't interfere with the side extensions.
Good luck man!
