Hi, I am new to this forum and would appreciate a few tips.
I have a 12 1/2 lunch box planer (Jet JWP 12). I've been working with real old (30 yrs +) tropical hardwood (mearbau/ipil and selangan Batu).
The wood is killing my HSS blades, I typically manage to plane 30 ft before the blades are dull.
Most of the wood is clean, if not I belt sand off old varnish/paint and wipe down before passing it through the planer.
Given the significant down time, I decided to try carbide blades. As most US/UK websites would not ship overseas, I custom ordered some from china. Well, they were cheap ( about $26 before shipping for a single blade), and I have 10 pairs
( due to their minimum order number), I contemplated selling the others I don't need.
The bad news was that the blades were not sharpened adequately, the blades are dull. It needs a tiny fraction ( 0.1 mm more taken off the bevel)
How can I sharpen these ? I've built a jig for HSS blades , but is it worth while trying to lap these blades on a diamond stone ( DMT or equalivent)
