The Jacobs Armature Chuck Mode100CR, when mounted by means of tapered arbor in the tailstock of a lathe, replaces a center. It provides an accurate support for turning~round work when a center can not be used. The stationary brass jaws provide an excellent bearing surface. The jaws can be adjusted to the diameter of the work to be supported and then locked.

TT Tap Collets are used in the Hardinge® TT-5/8 and TT-3/4 Tap Holders. These collets are stocked in ANSI (USA) and ISO (England) standards. The ANSI Inch-series tap collets relate to taps manufactured in the United States. Metric collets manufactured in the United States have the same shank sizes as those used for the inch series. The metric collets manufactured to the ISO standard have different shank sizes than the ANSI series metric collets.

Making a square bushing to grind lathe tools in a round collet
The Gorton 265 needs one of these for making hss tools. I have a 1/2″ one but the bulk of my lathe tooling is 3/8″
This video is a huge help
Helps eliminate chatter and stick-slip of slides and ways
Improves finish and quality of parts
Helps reduce wear and keeps sliding surfaces smooth, lubricated and clean
When you need oil for your machine, many types of oil will work – even motor oil. However, the best oil to use is oil designed specifically for lubricating machine ways. This type of oil has an additive that helps the oil stick to the surface.
Mobil Vactra Oil Numbered Series products are recommended for the lubrication of machine tool slideway systems. They are designed for use with combinations of cast iron, steel and non-metallic way materials. Mobil machine oil may be applied by hand, forced-feed lubricator or in flood application by circulation system.
Mobil Vactra Oil No. 2 is also suitable for circulating application in large machines and as a moderate duty hydraulic fluid. Mobil machine oil can be used for lubrication of ball screws, linear guides, headstocks, translating screws.
“Cutting oil is designed to flow TOWARDS the heat.
Way oil and motor oil flows AWAY from heat and smokes off more readily. You can probably use cutting oil for way oil, although that is not the most economical use for it”
