    The hard skin is usually not terribly thick. An electric portable disc grinder can get through the skin and let conventional tools cut the rest. You can run a quick test to see if the grinder went...

    The caliper picture is fuzzy, but it looks like it reads 5/8" for the top of the T-slot, which is the common size for that sort of mill. A set of 5/8" T-nuts with 1/2" studs and 1/2" flanged hex...

    You mean Malco Eagle Grips, not Matco. Malco is a big name in HVAC sheet metal tools, and some will have the new Eagle Grip handles on the traditional sheet metal tools.

    The above is probably quite accurate if in reference to a DSM-59 turret lathe. I have an ESM-59, the WWII-era previous model turret lathe and have enjoyed making a few thousand assorted neat little...

    Good news, Rick. I have some T-shirts around here somewhere that were supposed to be a ticket to ride that train. I guess I need to find them and schedule a visit.

    The short answer is that they do manual turning, facing and boring with greater precision than the average engine lathe. When in good condition, they can do a surface finish that you could mistake...

    I looked in my 1982 USA Maximat Super 11 sales brochure today and saw that the USA version has a D1-4 spindle nose. All the pictures show a drilled flange with a note that the picture does not show...

    On my first Hardinge lathe, I found the ball thrust bearing at the left of the pulley and a fiber washer at the right end and there was an adjustment for end play. I found there was enough room to...

    My first thought is that Hardinge used a ball thrust bearing at the left end of the headstock pulley from their first lathe in 1903, so it is a good idea. They did have a steel shell to cover the...

    German for thread pitch is Gewindesteigung, so Gg is probably the abbreviation. Languages with long words certainly need abbreviations.
