I was lucky to get acjacobson to make me one of his great checkmakers in 7 MM. Knowing that .014 alum. was not thick enough for 7 MM [ .253 + .028= .281] I got some of Latherunners .016 rolls [.253+.032=285] works great. Any of you looking for a great tool for 7 MM might try twisting acjacobsons arm. Any one wanting alum. in .016 try Latherunners rolls dead soft and forms great.
