G'day everyone,

Now that I have a press for the workshop, I now need some proper tooling for it. One thing that has been on the top of my list of things to do with the press is to cut keyways into parts (mostly gears). I have ordered a off the shelf 3mm keyway tool, however a the 5mm broach which was for sale was too tall for the press. So in this video I will try and recrate one using a piece of O1 tool steel.
