I have been making my Oland tools after the manner of Knud Oland but
whatever works for you, works for you. He made his tools as I illustrated on
the web site by drilling a round hole in the end of a round, not square,
tube and inserting a square tool bit in the round hole. It was held in place
with a set screw. This is a simple arrangement that works well. I drill a
hole about 2" deep for a 2 1/2" tool bit so that as it shortens I release
the set screw and bring up some more tool bit. When it gets too short for
the set screw to hold, I insert a new tool bit. If you braze it on, after it
gets sharpened down you have to remove it and braze on a new one. For that
matter, the set screw lets you take a half dozen inserts for a demo without
having to take a grinder to sharpen, just use a new tip. If you occasionally
need a different grind you could make a new tool or just switch tips.
