Wheeled clamp - video

[Toolmaker51]

PJ's knows about my giant solid oak table from Long Beach Naval Ship Yard lofting room. 5'5" x 14', I estimate 350 pounds.
A roller is imperative come moving day from garage to my building. The rolling clamp is good, Beserklyboy's tandem trolley even better. The weight issue is minor compared to astronomical center of gravity and length.
