No luck finding cheap offcuts anywhere and I didn't want to risk the scrap yard and end up with something unknown that I couldn't get a finish on, so I paid retail price for this lump from a steel supplier near work yesterday. 4140, 200mm diameter, 75mm long (or thick I guess). I've never milled a T-slot so starting with a circular one has me nervous. I'm thinking of using a trepanning tool in the lathe to cut the opening of the slot, as I'll be facing it and cutting the other features in the lathe- anyone got any thoughts or advice on that?
