Alignment cones 2x2.75 x30°

[Frank S]

That's simple just follow my threads as I post them the next thread http://www.homemadetools.net/forum/set-up-block-63032 shows them in use. They are only needed for setting up and locating the center of a bore to be bored out Since I am only having to bore the 2 plates stacked together set up is fairly straight forward care must be taken to make sure the bar is perpendicular to the plates which would be much easier when dealing with a fabricated part where the plates are say a foot or more apart like those of a backhoe bucket or the bearing locations in the boom but the concept never changes a pair of well fitting tapered cones on a cylinder pased through a bore or pair of bores will locate the center or said bore
