A 6 inch long boring bar mounted in a QC tool holder. The 3/4 diameter
steel boring bar accepts 1/2 shank C2/C6 brazed carbide boring tools or
1/4 square HSS tools in a 1/2 diameter adapter as shown. The cutters are
secured by set screws.
The same boring bar in a shop-made holder that replaces the regular lathe
toolpost, using the same mounting stud. This is a very rigid setup.
Tool holder and tools for the regular four way lathe tool post.
The cutting tools are ½ shank C2/C6 brazed carbide or ½ shank
home-made insert holder. All tools with ½ shank fit in the ¾
boring bar above. (Note that the aluminum tool holder was to be
temporary, made thirty years ago - somehow I keep finding uses for it.)
