hand made end mill?

[taterbug]

ok guys, my memory is getting full, so Im not sure Im remembering this correctly.

Did one of youse smart guys make an end mill by hand?  For cutting on a tumbler?  Maybe?  was it called a tumbler mill?  I'm trying to search, but I'm obviously doing something wrong...

Thanks for the help...

When I made lock tumblers using a link to connect the mainspring I altered a 3/32x1/2 Woodruff key cutter by thinning it .020  to .073 for slotting the arm of the tumbler and I have have them from common drill rod but the altered ones work better.An end mill is another type of tool and MIGHT be made by altering a drill by grinding it flat across the end and reshaping it to establish cutting edges and flutes that can cut.This can  be a study in altering tools but end mills are Noe cheap and in abundance from a wide variety of industrial supply shops.

Best way today is to just use a lathe.  You could have someone turn you some tumbler blanks pretty cheap if you don't have one.
