Re: Need help identifying feed screw threads on Smithy AT-300

Yes like Harold said there were very accurate screws made on manual equipment, and if you go looking, the high accuracy ones and some of the better lathe and machine tool manufacturer's verified there's on specialized test equipment that could measure lead/lag errors in the screw pitch. If I recall ...

Re: Need help identifying feed screw threads on Smithy AT-300

Accuracy costs, the more you want the more it's going to cost. However that dealer has already proven the supposedly interchangeable items there stocking and charging you for aren't worth buying if the fit between those critical parts is that bad. If it were me I'd be thinking of how to do this righ...

Re: opinion; old German milling machine

The 7th and 11th pictures of the speed and feed placard shows inches of feed per minute. The machines old enough it could very well be imperial. Not insurmountable if you cut close to dimension, measure as you would be doing anyway and then use a magnetic base with a metric indicator against whichev...

Re: opinion; old German milling machine

On the surface that looks to be a good stout machine Liveaboard. No nod on the head but that's not really an obstacle for most and it makes the head much more rigid. From what I can see the table looks to be free of those apprentice marks as well. That hand wheel seems to indicate it does have a qui...

Re: opinion; old German milling machine

Depending on the mill design Spro quite a few of them didn't have what we would think of as a table Y axis. Most of them seem to use a hand operated and/or power fed ram for the Y. I think that's what they mean about any mill having an advancing head.That was done probably due to the variety of tilt...

Re: opinion; old German milling machine

A whole lot of these Euro style mills are far different than what were used to in N.A. with our almost universal use of Bridgeport types since many come with built in power feeds in both X,Y and on the knee. A multitude of different heads were also offered as well as some having those quill feeds. S...

Not as far as I know John, I've ordered tooling from the UK and Europe without any duty owing.

Re: opinion; old German milling machine

510 GBP is probably dirt cheap for a machine like that if it's in good usable condition. For obvious reasons it's extremely difficult to request internal pictures of the machines spindle tapers, but it would be a question I'd be asking any seller about. And any rust is not a good thing. It would be ...

Re: opinion; old German milling machine

I'm the opposite and passed on a beautiful condition Deford lathe in the UK when I was looking for a new lathe simply because it was metric. It's now likely most in Europe would prefer a metric machine though, so anything imperial likely sells for quite a bit less. A mill is different than a lathe (...

Re: Help with a morgon model cbl-940 lathe please

Proper way oil on the way's and slides does imo make enough of a difference to be worth the effort of getting it. Vactra no. 2 is one brand. A light weight machine oil or even hydraulic oil can be used in any areas with bushings. The head stock I'd want to go with the factory recommendations. Deterg...

Re: Lathe table build

That looks like it's going to be a real pleasure to use Glenn. My mill is the same with the motor rpm display on the vfd, I either run it at 60 Hz where the factory numbers should be close for each pulley ratio or I have to calculate what the spindle rpm should be. I really should add a cheap sensor...

Re: opinion; old German milling machine

This is only one web site of many giving spindle taper standards.http://www.tools-n-gizmos.com/specs/Tapers.html Since your in Europe, then a Google search from there would turn up better and more specific European web sites giving the angles and measurements. The Germans have a set of standards for...
