An idea for putting a square hole at the end of a round one, without having to use special tooling. Mill brass bar stock into a pair of small L shapes, with one leg just as long as the width of the tap shank.Position the two pieces to make a square hole then silver solder together. Cut off excess leg length. Turn the outside of that assembly round, and smaller than the OD of your tap hat.Counterbore the top of the tap hat to fit the square hole piece then silver solder together. If the L parts could be held together for the turning, the assembly could be silver soldered in one step
If you're making these with through holes, you could make custom sized square broaches to push through. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
