I’ll assume by vibration you mean an unbalanced chunk a wood. If the lathe is vibrating with lo load something is wrong with it. I owned the same lathe. Add a shelf and put several hundred pounds of weight on it. Create a “torsion box by closing in the outside of the legs on each end, and close in the back. Makes for a ridid stand and adds mass so the lathe doesnt jump around with unbalanced work.

Many have put a shelf under the lathe and put heavy stuff on it

i did away with the flimsy metal legs and built a stand on wheels, that lock, large shelf, stack blanks and misc. on, i still use it even having the new to me Jet unit, i learned on the dang thing, kinda hate to send it down the road
good luck, sure is fun

I’ve got a 15.5×49” hickory slab and a bunch of 8/4 hickory sitting around doing nothing.

Mass is the key. A heavy stand to absorb the vibration will make a big difference. If the lathe is fixed to the stand rigidly, I doubt if there’s much improvement to be made in that arena.

The crawling and vibration problems are closely related to the feed speed, so the speed loop and system parameters of the feed servo system must also be analyzed.

Feed speed cut depth and tool edge speed)is operator controlled, there is no speed loop or system parameters for a reeves drive.

If you don’t want to make a dedicated stand, just attach it to some plywood and clamp the plywood down to your bench basically joining the bench’s mass to the lathe. You don’t need a long sheet—just 2 pieces big enough to attach to both ends and to accommodate clamps (that are not in your way). On my Excelsior, which is a clone, I usually was able to dampen vibrations from unbalanced blanks simply by attaching a couple of clamps to my bench that would sort of corral it into place. If it is so out of balance that didn’t work while turning at a slower speed, I would remount the blank so it was better balanced or take it to the band saw to cut off a corner or something to balance it better. I only had a couple of blanks where I had to clamp the lathe down.

I built a base for my husband’s lathe. Added weight in the bottom section.
The enclosure and platforms helped to make the stand very sturdy

I am in process of buidling a bench / ballast box for mine. Mind you, the lathe itself isn’t light, and if you use say 2 bags of quickcrete for ballast, you will suddenly be around 300lbs before storing any tools on it. Moving it may become a problem. I have not removed the bed extension behind the head even thoguh I should…

As far as unladen vibration, not really, at least nothing that cannot be attributed to a decade old drive belt now.

When it DOES get shaky, it is because I have put an out of balance work piece on it, and haven’t trued it up / balanced it yet. The vibration goes all the way through the base to the feet and it kind of dances.

FOR NOW, I have a platform across the spreaders, and I can put a foot on it and hold it down without any trouble, however a ballast / storage cabinet would be best, or a couple of tool drawers and ballast box like BB1 shows works well too. Just put a bag or two of quickcrete in there, or even just play sand, old cast off dull drill bits, broken wrenches, anything to add weight to hold it down…
