Crobalt cast alloy is an alternative tool bit to the 1/4" HSS tips usually used in the Diamond Tool Holders, its ideal for turning tough materials such as stainless, cast iron, and high carbon steels. Tougher and less brittle than carbide it can be ground using a normal aluminum oxide wheel, Crobalt contains 50% cobalt with the remainder being tungsten and chromium, there is no iron or steel in the alloy.
Watch the Diamond Toolholder in action doing a comparison test between M42 HSS (CoHSS) and Crobalt cast alloy -- both toolbits are 1/4" square.
They are being used in a Right Hand 12mm model Diamond Tool Holder, to turn 304 and 316 stainless bar and an interrupted cut on a piece of cast iron.
The lathe is a 1960s Colchester Chipmaster.
The Crobalt tips are 1/4" x 1/4" x 1 1/2" (6.35mm x 6.35mm x 38mm) and they come with square cut ends to be ground to the correct angle by the customer, using the Diamond Tool Holder grinding jig that comes with each tool holder kit.

Crobalt cast alloy is an alternative tool bit to the 3/16" HSS tips usually used in the Diamond Tool Holders, its ideal for turning tough materials such as stainless, cast iron, and high carbon steels. Tougher and less brittle than carbide it can be ground using a normal aluminum oxide wheel, Crobalt contains 50% cobalt with the remainder being tungsten and chromium. There is no iron or steel in the alloy.

The Crobalt tips come with square cut ends to be ground to the correct angle by the customer, using the Diamond Tool Holder grinding jig that comes with each tool holder kit. This particular size is specifically chosen to work on the ML8 Diamond Toolholder, both Right-hand and Left-hand models.
Crobalt cast alloy is an alternative tool bit to the 5/16" HSS tips usually used in the Diamond Tool Holders, its ideal for turning tough materials such as stainless, cast iron, and high carbon steels.

Drilling, Reaming, Tapping and Milling on the Drill Press. Many people sell the drill press short when it comes to machining. Rudy demonstrates many operations that make it a very important part of your shop.
Watch a brief clip from the DVD.
Did you ever wonder how high the valves should lift; what happens when you scale it up or down; how big the inlet passage should be; why small engines run so fast; how heavy it will be; how the flywheel effect changes with size; how to set your lathe for greater accuracy; or how to check tapers and angles? Rudy describes and illustrates his real world approach to problem solving on these and other subjects in the shop and at the drawing board. He includes an outline and drawings of examples used in the DVD presentation.

This DVD is an introduction to flux core arc welding, featuring extremely close-up demonstrations of actual welds in all positions. Steve discusses equipment, welding wires, fundamentals, self-shielded and gas shielded types. 56 minutes.
The FoR Inverted Parting Toolholder operates with the blade held in an upside down position and can be used on front or rear tool posts.
For lathes with a screw on chuck the holder must be used with a rear tool post.
Parting blade not included.

This DVD was produced in 2002 provides a "working knowledge" of the technical aspects, plus the welder skills necessary for using the Gas Metal Arc Welding process, commonly referred to as mig welding (solid wire with an externally furnished shielding gas). This process has been used in industry for a long time, but with the development of smaller, less expensive welding machines, it is becoming widespread in home shops because of its ease of operation. Steve also covers safety concerns inherent with all welding procedures. 45 minutes.
Rudy discusses lathe cutting tools in depth and then describes how each would be ground properly for optimum metal cutting. Also included are plans to build a grinding table that will increase your accuracy when grinding your lathe tools. For those of you using the Diamond Toolholder, Rudy goes into great detail about grinding the toolbit for it. 1 hour 45 minutes.
