I haven't fallen off the edge, or given up. I have my scraper with carbide blade. The sharpening system is functional. I even got a bigger granite plate. My efforts have been going into making the straight edge that I will need for fitting the dovetails. I got a hunk of Durabar and started carving. Visual inconsistencies showed up in the metal while machinin the bar true. That was thrashed about in http://www.hobby-machinist.com/thre...o-peel-off-of-virgin-metal.43907/#post-376831
The bar is squared up as much as my machinery is capable of. The angle that allows the straight edge to enter the dovetail is cut. I am now hogging out the lightening pockets. The photo shows the pockets already drilled. I should get an end mill holder today, so that I can proceed to the removal of the rest of the pocket. I have had persistent problems with the mill being sucked out of the collet when taking heavy cuts. I am hoping that the holder with its set screw will keep the depth from increasing. I expect to stress relieve and final machine the straight edge next week.
