jacks
Kurt Loup, Baton Rouge
>Chris and Joe,
Yes, they are trailer tongue jacks I purchased from Harbor Freight for about $13 each. I replaced the crank arm with a bicycle sprocket as can be seen on my tablesaw. The bicycle shop gave me enough chain so that I can link 4 together at each corner. They will mount to the inside of the stretchers. My tests show that they will easily raise the bench, but I'm not sure if the smaller footprint will be too unstable. If stability is a problem, I can slide blocks under the feet or slide a block underneath with casters to move the bench around. The jacks will provide between 12-18" of adjustment over the current height of the bench, 33.5". I can easily turn the sprocket by hand. I expected more resistance with the weight of the bench, but it is actually not much more resistance than turning without a load. The jacks are rated for 2000 lbs. each. The bench hidden in the back is a traditional cabinet maker's bench with a shoulder vise and tail vise made from plans in the book Making Workbenches by Sam Allen. I like the shoulder vise, but I don't like the holding power of the round dogs. The angled sqare dogs hold better on the new bench. Can't remember if the round dog holes are angled.
