If I had room for a 20 liter drum of oil, I could've bought a bigger lathe. Mike Taglieri miket--nyc@... Everyone has his reasons. - Jean Renoir "The Rules of the Game"

Group: I do allot of research building my machine and find much of the sought information very hard to come by. I had posted a request a few days ago about saddle gib adjustment dimensions and

My copy isn't handy so I can't confirm this, but I think there's a section on electric motors and their acceptable temperature rise in Machinery's Handbook. Mike Taglieri miket--nyc@... Everyone

By the time you get spindle & LS at exactly the right place you'll have spent far more time than if you simply reversed with the LS engaged. Cutting integer imperial threads with an imperial LS there

Ian, I don't think it would work, because what you are trying to accomplish is to get all the changewheels back, relative to one another, into the same "start position", and for threads foreign to the

Hello Chris and Ian, Don't worry about the name, Ian - I'll answer to anything. My "Warco WM180" is 7x 12, and shares a lot of features (saddle and everything above it) with a regular mini-lathe. It's

G'day John et al. Thank you for replying. I have had a few moments to digest what you are saying. Spindle angle is also important in the equation. Thus the Spindle must be at a set angle, the saddle

John's right. When a leadscrew is used to cut a pitch of its own "nationality", the right place to engage the half-nuts turns up frequently. Imagine holding two rulers, ruler 1 graduated in 16ths of

Hi Ian, Half the time I don't understand myself either so don't feel bad. ;-) Put a handle on the spindle and install the required for metric gears onto the lathe and walk through some turns with a

G'day John. I saw the timing of some of your missals; quite late. With a metric LS the chaser dial does not have the same relationship to the thread as for imperial. Apart from really odd-ball threads

Hi Ian, An extended tag - I'd never interpretted that passage quite that way! Just thinking out loud, if you had your RH carriage stop and always started from there, dropping the half nuts in at the

Hi Ian, You are making an assumption that when the lead screw is at a specific point when the spindle is at an equally repeatable location. That's essentially how the thread chasing dial works. If you

G'day all. On another topic, John (born4something) and I have been discussing thread chasing dials. If you have a metric lead screw you need a range of pinions on the dial to suit different threads.

Chris, The best bet is to find a good supplier of unbranded lathes that come from the same manufacturers as the branded models but cost from ?260 - there's no need to pay more. You can get a model

G'day Chris. CORRECTION. The guy was Andy Franks not Alan. My apologies Andy. One good trun deserves another. Regards, Ian wrote:

G'day Paul, Just to say what you said is great. Making tools, to make tools, to make tools.......... One good turn deserves another. Regards, Ian wrote: spindle,

G'day Chris. Have a look at the machines close-up if you can. A guy named Alan from the UK sent me a picture of his lathe, I think it was a Chester, and it had some significant improvements over the

A rule of thumb for the max projection from the chuck jaws is 2-3 times the diameter so a 3" long piece would be fine Gerry Leeds UK
