Darrell,
Since you are the group guru on Oland tools, how many different grinds do
you use on your Oland bits? Also, do you normally use square tools bits
like
metal working bits, or round bits made from drill rod? TIA

Ken.. Darrell gave you the best possible answer, let me give ya the mickey
mouse
way.. (my specialty for years)

My 2 favorite Oland type tools are 3/4" dia bolts, about a foot long, with
3/8"
holes drilled in the threaded end and a hole at a right angle to that one
that's
threaded for a set screw...
Gives me a nice weight and feel and was very quick and inexpensive...

My reason for a round hole for the square peg, besides not being equipped
to
drill a square hole in a bolt, is that the set screw sitting on the flat
of one
side of the bit keeps it from rotating... since I grind the threads off of
the
bolt and grind off excess thickness around the bit hole, i tend to
orientate the
set screw in an "up" position and always put the bit in to fit that..

As to grind, I like to have several tips (cheap in bulk or from Harbor
Freight)
available.. a few sharpened roughly as Darrell points out, but mostly I
grind
whatever shape I want at the time for what I'm turning..
They're cheap and hold an edge well, so I might turn most of a box with a
rounded tip and then re-grind the tip to a flat skew or box scraper to
finish
the inside of the box... YMWV

Darrell, Mac,
Thanks for the input. I have been using a home made tool using 1/4 & 3/8 in
drill bits in a piece of cold roll 5/8 in bar stock. In the business end
there is one hole drilled straight in from the end and one at about 45
degrees so they intersect so I get by with one set screw. The grinds I've
been using mostly are similar to a minature round nose scraper. When Darrell
mentioned Oland grinds , I thought There might be a lot more than I'd been
using. Thanks.
