    4 jaw Bernerd 34M for Myford 7

    Thread Identification

    Looking again at your photo djswain is correct the pitch does not appear to match your gauge, try a 19 TPI gauge, this is used on British pipe threads but the diameter you quoted does not match any standard BSP thread. Where in the U.K. are you located ?

    Thread Identification

    To late to investigate further tonight but if it’s clearly an imperial pitch 20 TPI why measure the diameter in metric ? Your measurements equate to 0.7409” which suggests it’s 3/4 x 20 albeit 0.009” undersize, possibly a UN special I.e. none preferred size.

    Emco Maximat Super 11 Threading Lever

    Denn, Only just noticed this post, did you get the machine sorted? Peter above is correct regarding the feed/screw cutting lock system and this sounds to me to be the most likely cause of the problem so a strip down of the apron will be needed. Do you have a manual? I have the original that came...

    Advise on Myford leadscrew

    Basil, I just spotted this site ACME Leadscrew | ABSSAC They seem to do a suitable Acme threaded bar you could use to fabricate a new lead screw from, no prices but worth a call I recon ! John

    Advise on Myford leadscrew

    Alex, point taken, however as you point out Mazak is great for complex castings which this item is and you will find it is more wear resistant than you imagine. For a great many years Delapena used this material for replacement shoes on honing mandrel’s and I can vouch for their longevity...

    BAZMAK-Diary of a Myford super 7b lathe restoration

    Hi Baron, Don't want to clog up or hi-jack Bazmark's thread but if your interested the adaptor blank I used came from Myford [25 years back ??] I think they still do them Main point is they are much larger diameter blank and longer than any others you see many of which will be far to small or...

    BAZMAK-Diary of a Myford super 7b lathe restoration

    Hi Barry looking good but I would consider alloy for the shear pin, I think steel / iron may be too strong. Better too weak in the event of an error. I was going to add a photo of the shear pin for the Emco but failed ! guess you have to make an album on the site first ??? However it is soft...

    BAZMAK-Diary of a Myford super 7b lathe restoration

    Hi Barry, I have a pretty much identical machine purchased new around 1977, mine has the power cross feed as well. Regarding the bed casting I am sure they are considerably beefed up on the long bed, the casting is deeper thus keeping the stiffness and rigidity of a standard bed. One thing I...

    HSS Lathe form tool shaping

    George is on the money here, I too have made many HSS form tools this way for producing one to form a sphere or half sphere, it does depend on how accurate you need to be, is the sphere functional or cosmetic? I have also dressed a wheel to size to make the form. There is also merit in using...
