Ceramic Tool Holder, P/N 2265
In the past decade, use of carbide insert tools has become standard practice in professional machine shops and also in many home shops. Carbide allows you to cut harder materials like stainless steel or titanium and abrasive materials like fiberglass. However, if you want to cut hardened tool steel the newer ceramic tools make that possible, even on small home benchtop machine tools. Sherlineís holder includes a triangular ceramic insert. The shank is 3/8" square, so it is held in the optional P/N 7600 tool post. Learn more about the ceramic tool holder at www.sherline.com/2265pg.htm or read more about using carbide and ceramic insert tools at www.sherline.com/carbtool.pdf. Order Sherline P/N 2265 ($60.00).
Shop Tip of the Month
An Indicator Holder for the Lathe by Jim Knighton
Completed indicator stand shown in use on the lathe
There are times when you want to use a dial indicator to measure runout on a part being chucked up on the lathe. On big machines, machinists often use magnetic based stands to hold the indicator, but the Sherline lathe is primarily made of non-magnetic metals, so what to do? Some people screw down a thin steel plate next to the lathe to take a magnetic lathe, but Jim Knighton has a good solution on how to turn an indicator stand that clamps right to the crosslide table. He shows setup photos of how he held the material to turn it on the lathe and a photo of the finished stand in use. See www.sherline.com/tip45.htm. With a little aluminum and a spare hour or two, you can add this handy fixture to your shop.
