Morning all.
I'm after a bit of advice as I'm just starting out with my Hercus 260.
I want to make a boring bar with a HSS cutter.
In principle I'm thinking a 12mm or 16mm mild steel bar with a 3mm or 6mm hole cut through the end at 45 degrees to the work and a grub screw to hold the HSS in place (3mm and 6mm DIA HSS seems readily available on eBay).
I want to be able to bore down the length of the piece and then face the inside off with the same tool, hence my thinking 45 degrees to make grinding the HSS easier.
Questions.
1. Does the above (45 degree) bit sound feasible / practical or is there a better way?
2. I suspect i may need to bore a few inches deep and maybe 1 - 2 inches diameter. With this in mind what size bar and HSS would you recommend?
Any thought or ideas would be most welcomed.
Thx
Jon
