putting feet on mill?

Aug 12, 2004 8 Replies

I am finally too embarrassed with the 2x6 wood pieces my Shizuoka B-3V bedmill has been resting on since it was delivered...oh, only two years ago! :-o



I have 4 feet that came with the mill, each is a steel cup thing with a hard rubbery insert. The steel cup is threaded for a 5/8" bolt. The mill has these ~1.25" threaded studs with a through hole for the 5/8" bolt. I am assuming you turn the studs to level the machine and the 5/8" bolt is just to keep the mill from slipping off the feet?



Ok, so uhm, how do I raise the 3.5 ton mill to get the feet on? I see a way to do it by going back and forth with shims and the leveling studs, but uhg...



Also, once the feet are on, what procedure should I use to level the machine. I read somewhere that you can tweak the feet on a mill to get that last little bit of accuracy. Should I worry about that or just get the machine level with the earth?


Thanks

Rick Do the feet you have look like these;

so then you use the 1.25" threaded stud to set the height of the machine and coarse level. The 5/8" bolt screws into the 'hat' on the mount and expands the mount to do the final leveling. Take the 5/8" bolt and grind the end of it till it is flat or slightly convex and grease it well before installing it in the foot. If you don't grind and grease then the bolt may gall to the mount, experience speaking here. Do not expand the foot more that ~3/8" as it may separate. The 5/8" bolt must be tight to the bottom of the mount or it is not correct and may move/settle a bit. The mfg site is

and your looking for leveling mount information. I'm guessing that you have LM5 mounts or equivalent from another mfg.

As far as raising the mill, use the 1.25" studs. Don't they screw in from the top? Raise the mill on the front end by screwing the studs into the base, grease 'um good, and onto the 2 by. When the front is off of the 2 by then shim up under the base behind the studs, back off the studs to release the 2 by and install the mounts on the front. Now raise the front pretty high so that you can get a spacer/pivot under the base, near the back, lower the front so that it rocks over to the front lifting the back and remove the rear 2 by and install the rear mounts. Use all 4 feet to raise the machine off the pivot. Set to height with the studs, and level with the mounts. lg no neat sig line

See if the local rental yard has a "Hydraulic Maintenance & Repair Kit" - e.g. a Hydraulic Jaw of life or spreader beak - that can get under the foot area and push up (You do have wood there) (you could cut a notch out for a point to lift on. It typically has spreader bars that can be against the floor and a lifting point inches above also.

then top search for EU09050881 with MSC part number just below selected. Gives you a picture of what I'm thinking of and what to show or just to buy.

e.g. one pumps it up - blocks under something to hold if the pump fails - then add footings on that side.

If you have a square object - not a long or wide base - then you have to lift by overhead hoist.

You might go this way with the hand pump - jack up all corners - around and around - blocking and leveling as you get higher and higher. Once up - then put on the feet and jack it up - take out shim and round and round you go down the stair steps of shims that makes the taller stack... until you are out and on the feet.

Not an easy job - hoist or the like is faster and easier. Still block before you work under the floating mill.

Thanks Larry,

I uploaded some pics of the feet to the metalworking.com dropbox.

Here is a closeup of the 1.25" stud (I really haven't measured it, just eyeballing):

The 5/8" bolt in that pic was from my junkbox...I don't know where the original bolts are. It does seem as if the 5/8" bolt presses down on the metal plate on top of the rubber pad...perhaps expanding it like you said???

Here is a shot of one side of the mill, showing it unhappy resting on wood:

Poor mill...it really wants some shoes.

I am going to try your grease and go idea tommorow, along with a large stack of shims....should take me oh, say 4 hours of turning (not much travel on those

1.25" studs. I tried a test lift of the mill with a solid steel 8 foot prybar...Mill 1, prybar 0. Damn big mill....sigh.

No railroad jack in the area? I love mine for just this sort of thing. Jack up the front until its high enough for the feet, install, lower and repeat on the rear.

suspect Gunner has one of these beautiful tools.

The 86A to be exact. Not bad for a $5 yard sale find, no? Its one of my most cherished possessions.

Little late now, but that pic was of a mount without the rubber insert. Adding the rubber insert makes it about an inch or inch and a half taller. Anyway, all mounted and done now!
