I have selection of wrench’s and sockets that have been modified over the years for various one off jobs, in imperial and metric. Some were made from my “good tools”, but sometimes that’s all you have and it’s going to be the only way to get the job done. Now I also have 2 drawers full of sockets, wrench’s in both sizes just waiting to be modified, though often it is a size I don’t have that’s needed, why is that??? To small a wrench can be made larger, too large can be made smaller, welder if there’s one.
Had to make a few wrench’s for the shaper, neither standard imperial or metric, one or 2 much thinner. From a time when 32 seconds and 64ths it seems. Modified and size stamped.
