Worked in the cool of the early morning making the 1" thick top plate for the hammer. Had a length already torch cut so I put it in the mill to square it up and get the length precise. Marked the 14 holes in it, punched, pecked, drilled to 5/16, set it atop the hammer on the ceiling plates, aligned, clamped, mag drilled through the 5/16 holes, removed the plate, drilled to 27/64 in the ceiling plates and power tapped them to 1/2 13 tpi. Drilled the top plate at the drill press to 9/16. Then made a short plate for the mounting of the aerofoil using the top plate holes and a transfer punch to mark the plate's holes. Drilled them in the drill press and then clamped the plate to the 1" top plate with bolts and set it atop the welding table. Made the aerofoil from 1"x4" flat with an annular cut hole for the lifting chain hook, and used the vertical bandsaw and sander for the profile. Notched it to fit over the aforementioned short plate using the vertical bandsaw and then sandblasted. The plate and top plate had been sand blasted earlier. Once positioned, I mig welded the aerofoil to its mounting plate using the bolted connection to the top plate to resist warpage deformation. Three passes of overlapping beads put a lot of heat into the assembly. Let it cool while I ran to town to fetch the sharpened dovetail bit, but was told sorry, Friday afternoon, blah-blah-blahcetera. Took lunch and then back at the 3rd world I worked on sizing the cast iron blanks for the V-guides. No shortage of things to do instead of cutting the anvil billet dovetail slot.

Hey John, I have a couple of sharpeners I use around baltimore. If you need someone additional let me know.
Have you considered setting up a shaper where you can sharpen the stuff yourself? Or perhaps getting a horizontal cutter custom cut? It could make hundreds of cuts before wearing. Seems your doing a fair number of dovetails these days!

Yes, I'm really busy. PTL. I'm experimenting with Toland and Son in Bel Air and will hopefully get their product tomorrow afternoon. Mikey called me about half an hour ago and I'll get his product on Friday the 30th. Mikey helped me years ago by grinding a regular HSS end mill into a 7 degree dovetail bit with spiral flutes. He's done four or five more over the years. So I'm very interested in your sources to find out if they can grind a bit from a regular bit like Mikey did. What he has been "really busy" with is selling two houses and buying another and being a newly wed. I do understand. I just need alternatives so that I can keep my fragile business moving.
