That format of mill is pretty common, there are bound to be a few people who have noticed prices on ebay or on this forum.

It looks pretty well cared for so I would hesitantly suggest £400, a good few are less but they last for decades and you can't tell condition from photos.

Reference similar-ish machines new:

warco

axminster

Around £350-£400 for this RongFu lookalike. Probably the 20 or 25 model. Good solid machine I have the Ajax MD version.

Hi Gaz, this mill is in actual fact, similar to the Chester Eagle 25, Chester Eagle and the Warco Economy, Warco Economy The size of the table, the position of the depth stop and the shape of the column base and also the spindle stroke are all pointers.

Regards Nick.

Checking for wear?

X axis. My leadscrew and nut were very badly worn towards the middle of the travel. I removed the leadscrew and nut to examine the wear and it was in a terrible state. I suppose you could see if the backlash is worse or better at the ends and middle of the slide travel to indicate the same issue. The same for the Y axis.

Z axis. You could also check for backlash in the worm and wheel. Again, mine was in terrible condition and required an eccentric bush to be fitted to the operating shaft to reduce the backlash to a reasonable level.

I'd say that the bearings might be tricky to examine without removing or stripping. Perhaps just run it and see how quiet it is or isn't.

You could also take a picture of the nice clean, shiny table with no prangs or drill holes. If it does have some mistakes, it is only fair to take a picture of it for the new owner.

Having said all this. Why worry if your friend is selling it. Just advertise it honestly indicating that its age and say that it has been used and allow the new user to make his or her mind up. You could try and check the backlash without stripping it as best as you can. From Nigel's research and my experience, it looks like a fair price might be £600?

It looks very like a Rong Fu RF25, sold by Warco as the "Economy", I think.

That may give a rough guide as to the current price.

Take a look at what dealers are asking for such a machine, but remember that a dealer has to make a profit, so will have added a mark up to whatever they paid for a machine. Consequently, your price should be lower.

Occasionally, there may be one in Warco's used machine list.
