Not sure this is the right forum but whatever! A while back I commented on someone’s post about a simple sharpening jig I had seen. (Credit to Robert Van Norman at Inside Passage) Anyways to prove the point I came across a blade Planner/Jointer that had seen at Kiefers place (Hitachi Koki F1000A) and bought it. got some new blades and made up this simple jig. After a bit a pm on this beautiful machine, honed the new blades installed them and was totally amazed with the finished on this basic 2 blade machine!
Jig is 2 slots cut at 45 degree’s in a chunk of hardwood then I start with a 1000 water stone rotated in a gentle fashion on top of the blades, followed by a final polish with a 8000 water stone! ? Hard to describe but very simple if you have seen it done. The results are amazing. The piece of Birch in the last pic is smooth as glass! best of all after blades start to dull just pop them out and re-hone them. Caution very easy to cut yourself so extreme care is required!

quite a few years ago I did much the same set up for my 16” planer blades.

Lived in a small town, so they had to be sent away, which I did, came back with a wave in em. Sent em back, got the same result. two weeks no planer.

cobbled up an arrangement similar to yours that attached to the grinder, did em myself.

I worked with some hard lumber, so had to use the grinder to get the “nicks” out,

It was expeditious and less frustrating than explaining to the local saw sharpener as to what was wrong with the non-straight edge on the product he expedited.

Nowadays I have access to really good sharpeners.

Downside on the wood guides on the grinder, the heat can start the wood smoldering. But it is a good workable method.

Good idea, if I don’t say so myself.

Need to make something similar for my DW733 blades. This reclaimed oak im using for my workbench has dulled/chipped 2 sets of blades one set is probably too far gone due to hitting a couple undetected nails, but the other just could use a good honing.

Just bought a new set of blades (2) and man they are very expensive!! Luckily I kept the old ones, just in case…well, me thinks that this is worth a try….nothing to lose but a re-furbished set of blades if it works!

That is a good jig Andre and similar to mine. I use a diamond stone to hone mine. First 600 grit and finish up with 1200 grit. Not as good a result as with water stones, but quite acceptable. My planer is also a two bladed one and it is part of a relatively inexpensive combination machine, but I have planed white oak, mahogany and hard maple with it and it does a great job, which I have to admit kind of surprises me. I’ve had it for about 17 years and it still does the business.

You said your blade slots are on a 45. Is that the angle on the blades?

Yes that is the blade angle, the purpose of the Jig is to put a micro bevel on the tips. After you are finished you will only see a fine hair line of Stupid Sharp! Happy to say that after running a bunch of birch and cedar trough the old Hitachi finish is still great.
