You need a few tools that are pretty special to the purpose. Michael Morgan used to sell castings to make a straightedge, and I bought one and scraped it in on a granite surface plate. I then made some right-angle pieces, also. You can get an Anderson Bros. scraper and a few scraping blades. I made my own blades from large carbide inserts, and ground them on a diamond wheel. Instead of the old timer's Prussian blue dye, I use Canode, which is water soluble. It is not as good as the Prussian blue, but a LOT easier to get off you and your clothes. You need to make angle gauges that are a fit to the dovetails to make sure you maintain the correct angle. You also need to make some traveling gauge mounts to assure the dovetails remain parallel to each other. There are a couple ways to do this, even a pair of hardened and ground shafts can be used.
