Tool Grinder (maybe)
#61
There's a couple of ways to do it, I can leave the tool mounted and swing the angle the other way and reset the clearance angle, or the method I use is to remount the cutter upside down and reset the clearance angle. A diamond hone removes the small burr that forms.
Here is a cutter I tried for the 14 1/2 degree pressure angle I need on the CNC plasma table racks. The Acme thread guage works nice.

thanks I have one also, looks like you need to put your thumb on top of the hammer not under it Big GrinBig Grin

after looking at your grinder I think I may take a stab at making something for my dual wheel grinder. have to give it some thinking first, to see if I can figure out how to make an adjuster that will allow me to push the bit in towards the wheel

Digging up an old thread, only been 6 years to get around to making another attachment, might actually get this thing tooled up by the time I die. lol
Found some interesting ideas on the net for drill sharpeners and combined them all.
First this jig aligns and positions the bit in the holder.

The plate at the front has horizontal lines scribed on it. The bit is positioned with one flute against a finger then slid along till the other cutting edge aligns with the scribes. The back stop is then set.

The older is then set in this jig that swings the bit over the face of the wheel. Cutting angle and clearance can be set to what ever. Here its 118 deg angle and 8 degrees clearance.

A screw under the holder sets the cut depth, spark out on both flutes and the web is centered.

The results on a 1 3/8 bit, could never get the edges even on this big a drill.

Actually two attachments, had to dress the wheel so made a dresser.

Note the wrinkle powder coat finish.

Glad I'm not the only one around with six year or older projects awaiting completion. Big Grin

Looks like it works pretty well, Greg. Thumbsup

Six year ones are the recent ones that I can still remember. Your just getting started on this retirement thing Tom, just wait.

I have two projects that are well over 10 years old and have yet to be started.  1) '66 Plymouth 2) early 1900's planner resto/mod Smiley-signs009
