I was servicing my made in Sweden Varnamo Mill, I made a oiler from grease gun to lube Vertical Head and when I oiled the Quill it snugged up and took quite a strokes for it to loosen up,tolerance must be tight.Was wanting to enlighten anyone who get's one of these not to grease those things that looks like grease zerks.When I finished refurbishing this machine nearly 3 years ago I greased the head and Hydro Locked the quill took me a long time to get it free and was tight for a long time after that.

Very nice machine! Does the round tag on the head mean 50 weight? I have a Swedish radial drill(not for sale) I still have to pick up.

Just curious: Is it possible that those are to be used with an oil gun? My Webb mill and the BP's with which I've come in contact use oil but they have oil cups with spring lids. My Webb will have a stiff spindle when cold in the shop, especially after oiling. I'm sure that tolerances on Mill spindles in general are in the low ten-thousandths range.

That's a very nice restoration.

It sounds like the grease caused a hydraulic lock up.

What I have learned is they are oiled with coupler similar to grease gun,but with oil.
That's a very nice restoration.

For sure that what locked it just thought I would share my experience,save headache for someone else.

That is a Brembo Hyd. Disc Brake for Tapping and for locking Vertical Head to do Tooling changes.

That is a nice looking mill. I think I saw one like it at an auction sale once. I was just wondering where they all universals?
That is the horizontal part in the column with the cap on it, isn't it ?

Yup, that machine can also be called the Brute Forcer mill, as it just doesn't seem to vibrate nor stop when taking beefy cuts. Weighs more than you think and has the feel of a solid heavy machine :)

You are correct that cover for horizontal that I am not using,is 50 Taper and had15 HP motor on it.

Ya Jaakko very pleased I saved this machine from scrapyard, is very sturdy!

lol, classic mistake.....you're not the first or wont be the last. Zerks on a machine tool are almost never for grease unless you find specific instructions for it otherwise. Make that mistake and there's not choice but to take it apart and clean

Nice.
Varnamo, and scandinavian stuff in general, is usually very well built.
Work is very expensive, and education is universal, so anything made in scandinavia has always had to compete at the high end.

Kone elevators and cranes are a good example.
(I come from Finland, and live in Spain, fwiw..)

Yes quality and design seems very good,very nice to operate and with it's size capabilities for it is just about endless.My first thought it was way to big,but would consider a larger machine.

I have stroked the quill about 100 times and is still snug is that normal after lubeing,it took six months for it to free up after greasing by mistake,the quill is 5" dia and has oil over entire surface.

Maybe it's been suggested, but can you remove that fitting? If so it's possible for some grease to expel. Perhaps moving it up and down with the fitting off will help free it up.

On a related note- some years ago I built a rotary table. I took special care to fit the rotating part to the base such that it moved freely but had no discernable play. It's been so long that I don't recall if I used any oil while fitting the parts, but I probably did use what's called Nutrol, which is a blend of solvent and light oil. Once I was happy with the fit, I cleaned it, greased it and tried to assemble it. The parts came partially together and seized. What a fricken hassle getting it apart again :( My conclusion was that grease molecules are larger than light oil molecules, enough so to darn near weld the pieces together.
