What is the magic of Boring Bar manufacturing?
I didn't want to hijack a currently running thread.
I don't get it. I have 3= 3/4" boring bars of different lengths that I found at yard sales. BUT, to me they look like 3/4" round stock fixed up on one end to accommodate a cutting bit. if a guy is working at home and not on a production setup, why is it so necessary to have a commercially built boring bar that's been heat treated?
I said I have 3 3/4" boring bars, but I have no 1/2 bars. I've had to make my own and it's not a big deal and they work for those times when I need to bore less then 1" holes.
I'll be damn'd if I'd pay $100.00 for something I can easily make for my home shop for about $5.00. I'd find another place for the money.
If I worked commercially I'd no doubt think differently as maybe I'd want to take deeper cuts to work faster. (btw, flea markets around here frequently have 3/4 and 1" boring bars but I've never seen smaller ones.)
related question: What can you do with a "face mill", in a home shop where time is in abundance, that you can't do with a fly-cutter? I'm asking because I really don't know. Would it be useable to de-bark D2 tool steel before machining? Knife makers chew up belts getting through the bark on D2.

Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.
It is true, there is nothing free about freedom, don't be so quick to give it away.
