HBM extension tool and tap grinding - YouTube (https://www.youtube.com/watch?v=WWU2xYBwEzg&t=56s)
Hello to all of you.
The last 2 months have been very busy hence no posts. I have been busy, with my boiler, ready for 2nd hydro in the new year.
My Kearns borer had a rigidity problem when working on larger holes so a heavy bar is in progress. Also a job grinding spiral flute taps has come up. As they are used in 4340 pre hard the regrind is not so easy.
Keep safe during the hols.
