I'm digging up this old thread because I was able to snag the original pictures on google. What caliber did you have this jig made for? I am making a 9mm can once my form comes back and I am hoping to find a jig to do the vent holes with. The design is great!

So good to hear your K baffle design turned out well! I am waiting on my first forum 1 stamp to come in for a k baffle design. How did you drill your holes? Did you have a lathe? I only have access to a drill press and am worried I'll screw it up.
