How to make Oland tools ?

The sides and bottom of the tool are beveled and the top is flat. What is the angle of the top face when you are cutting? It seems if you ride the bevel that you have a positive rake of 45 degrees and a sure catch. I must be missing something.

Thanks for your patience.

Derek.. I'll admit right off to being low-tech here...

When I'm working the inside of a bowl, I grind the Oland tip at the same angle as my bowl gouges... I have NO idea what that angle is, as I set up the jig to align with the bowl gouges when they were new, not to a specific degree..

Derek I must be missing something here. The face of the tool is angles at 45* from the top and you ride the bevel. I do it all the time without catches or at least no more than from a gouge. I seem to be missing the problem?

To me, one of the BIG advantages of the Oland-type tip is that you really have to work at it to get a catch.... the bevel on the bottom rides just like a gouge and the angle is pretty consistent with the angle of my standard tool rest... no problems with catches at all and nice shavings peeling off..

I guess I'll wade in here with my $.02 on how I make the tool.

-- I drilled a 11/32 hole, 2" deep, into the end of a 12" piece of 3/4" round mild steel rod.

-- 3/4" from the end of the rod I drilled and tapped a 1/4" set screw hole after having ground a 'flat' at that location.

-- I tapered the end of the steel rod to remove excess metal and to give it a sharper profile.

-- I intend to add a length (2'?) of 3/4" galvanized pipe to complete the handle. I'm having a bit of trouble finding a 'new' piece of pipe that will fit properly as most of the walls seem to be thinner these days and, as a result, the hole is more than 3/4". Guess I'll visit the junk yard

I found that the corners of the 1/4" HSS bits had to be eased slightly so that they would fit into the 11/32" hole.

I've taken the larger HSS bits and ground 1 1/2" of one end of each to a diameter that would fit into the drilled rod. This took a bit of time with my 6" grinder but the fit is good.

Thanks for the idea Darrell.
