Through the course of working on the Mausingfield action I took a moment to burn some video footage summarizing how we cut features like ejection ports. On the surface this fixture may strike some as being a bit elaborate and silly for such a mundane purpose as cutting away the stock to expose the ejection port. Its a deceptively simple process; one that can drive you nuts when your after the cleanest fit possible. Squeezing a stock from the sides in a fixture distorts it, so youll never get the receiver to sit right when attempting to inspect your work. This leads to lots of rework and chasing the rabbit when trying to get this spot on. This fixture uses the actual action as the holding device for the stock. That means the stock is essentially static. No distortion. With some creative programming were able to replicate the exact port geometry w/o contacting the receiver. This gives us the mirrored fit Im after and allows me to inspect the progress as is because the action is in the stock the same way it would be when assembled. The ability to rotate the assembly is a powerful tool because ejection ports (M700s for instance) are not parallel to the raceways. They angle downward. The ability to rotate the fixture means I can duplicate that angle perfectly. Hope you like the clip. Just tossed it together and stitched in some music so that it didnt look so Charlie Chaplin while watching it.
