Jacking up Gold Crown 3 to replace feet

Any suggestions for 'best practices" to elevate a GC 3 to replace feet? Don't want to cause slate seams to crack, Thinking hydrolic car jack each end?

1200 pound table so lifting by hand not in the cards.

Thanks

I made a brace out of some scrap 4x4 and 1" plywood for my GCI. I jacked it up from the frame.

That looks good & sound. One thing you might keep in mind... don't let it remain in a stressed situation... too long. That situation isn't too highly stressed, but it is on a angle. Hope it worked great for you....

Worked like a charm. I had to take the feet back to the powder coater because they didn't do it right the first time. I jacked the table up, removed the feet and replaced them with 3/4" bolts that rested on some 1" plywood pads until I got the feet back from powder.

Got a 3 ton floor jack ready. Ken said always lift from side NOT ends. Will acquire piece of 6 x 6 today. New feet due Thursday.

Thanks for your thoughts.
Hope leveling is easy.

Ends worked for me. No damage whatsoever.

Unless you have some machinist levels, you'll probably need a mechanic to come out and re-level.

No it is not. I did it on my Diamond Professional. Roll it, changed 2 feet, rolled it to opposit side and changed the other 2. Why would this be a joke? A lot easier on the slates than picking up the ends.

Diamonds are more or less designed to be shifted this way, the one piece slates that is. Not sure how they recommend to move the 3 piece designs. Different tables. It's like offering advice on how to work on a car by saying "first you need to unscrew the carburetor" because your car has one, compare same to same.

First, he lifted the frame, not the slate.

Second, the legs are not designed for that kind of side load.

Third, tipping the weight of the slates is problematic as you need to control the descent when it goes over center. The frame is made for vertical loading, not side loading.

Personally, I would have done two things differently. I would have used an I-beam spreader across the frame and I would have used a bottle jack. The bottle jack lifts vertical, a floor jack lifts in an arc, necessitating rolling or pulling.

I could be wrong on all of this, but I've done a lot of lifting, moving, and setting-up of extremely expensive equipment.

Good for you, I don't know that he specified anything other than replacing the feet. The Diamond Professional I have has the same feet as Gold Crowns. I replaced mine with the table completely assembled and useable by rolling one way, replacing 2 feet, then rolling the other way and replacing the other two. Set it down and relevel with the feet adjustments and good to go. Not difficult and no reason to make it difficult.

It puts an awful lot of load on the threaded inserts that the feet are threaded into.... On a Gold Crown (assuming that it has leveling feet), the threaded inserts are only held in by one tiny wood screw. Pivoting the table, as you suggest, will undoubtedly pull those wood screws out.

Additionally, with a 3-piece slate table, you had better hope that your slate screws are tight, and that your seams are glued.

Might not be a huge deal.... Might end in disaster....

Good for you. You didn't know what you were doing and it worked for you. Your advice is bad and I explained why.

One jack is all that is needed. Do one end at a time.
