I'm looking for a way to resharpen my planer blades, and other flat tools,
(and drill bits).
Once upon a time, a stone water wheel (electrically powered)was available,
but I don't see many around any more, they turned at slow RPM.
I always thought that slow and cool was better, when sharpening steel.
I found this tool ,http://busybeetools.ca/cgi-bin/picture10?&NETID2248180314081804725&NTITEM ฒ337, but the RPM is way up at 3450, wouldn't
that cause high heat on the planer blade.
Also does anyone have any experiance with a tool like this, what's the
accuracy of home grinders?
I've seen yet others that use a vented steel wheel with sand paper, and yet
others with a glass wheel and sand paper.
Should I just keep buying new blades, or just send then out for
refinishing, (have done both).
