Gotta love flea markets in Blacksmithing, General Discussion Posted August 18, 2014 There is actually a leg vise specific mounting plate that is supposed to go with that vise and to which that strap attaches. The strap as it stands now is not correct for mounting the vise. If you are not familiar with how the mounting system is supposed to work, I would be happy to take a picture of mine to show you. If your willing to send me a picture that would be great. I would much appreciate it, thanks.
