Make This Planer Blade Sharpening Jig 

Peter Brown I'll have the beer on ice :D

n8guy Maybe, if you are doing a ton of planing (which I'm not). Even buying the oem replacements, it would take a lot of replacements to come close the cost of one of those spiral cutters. I bought off-brand replacement knives for it for half the cost of the oem's and they appear to be just as good as the originals. Sharpen those once and they are half price again.

John Heisz Yeah, for me, one of the biggest advantages is the surface the Shelix leaves. By many accounts, there's no need to even sand afterwards. I think watching RU-vid user "mtmwood" use one like most people use a drum sander on end grain hardwood is what sealed the deal for me. But yeah, definitely a significant expense.

Mike Fulton Give it a try. When the blades are throwaways, there nothing to lose.

wordsnwood The nicks were deep and wide, and there's not much room (with the pins) to stagger them, so I'll have to live with it. Until the next sharpening :) I did that follow me panning shot in another video, the first zero clearance miter saw fence video, I think. The 4k video give a lot more flexibility for stuff like that and for just regular shots, since the camera can be further back and I can just crop in close in editing. I render my videos to 720p mostly, so there's a lot of leeway.

queazocotal Most of the big industrial models had knife grinders built in, at least the older ones did.

Shop built After these are dull again, I will see if I can get a second sharpening out of them. Looks like it's possible.

John Heisz Hy John! I don't know the Dewalt blades and how many sharpening you can get out of them safely, but I sharpened my really old homemade planer's blades 4 times already without problem (originally were 35 mm wide blades, now they are approximately 28 mm wide (I hit nails with them several times, that's the curse of recycling)). Now I'm planning to buy a new set of blades because I think it will be not safe to sharpen them again. With another full sharpening they can go down to 25-26 mm in width, and I think they will not seating securely enough in the blade locking mechanism (which is not a high quality one) to take the risk. But I think 4 sharpening out of 1 set is really a good result. Though I'm not sharpen them the way you showed, but on a dedicated blade sharpener machine at my friend. Best wishes from Hungary (and sorry for my poor English)!

***** This planer uses disposable blades that are indexed to the cutter head.

Sorry I missed that info (I watched your video at the office :))). Mines are machine steel blades with a very simple screw lock mechanism, and are quite wide originally and probably that is why I able to sharpen them so many times.

@@JohnHeisz Why can't you just keep sharpening them over and over?

GarageWoodworks I'd be tempted to grind them off, but the hold down bolt holes are pretty tight too, so not a lot of room to move. I figure it's best to try for one or maybe two sharpenings then trash them. If i had my time back, I would have bought a different planer, but I got this one at a pretty good price at the time.

John Heisz I too have been in this same predicament. Since it was a gift, it was hard to say no. Also, since mine was free, I have been considering the shelix head upgrade for this. Have you considered this or looked into it? I know ~1k total investment(at retail) would mean a lot for the planer and upgrade, but the carbide tips would mean ~3-4x longer durability per edge and are indexable 4x each blade purchase. From what I can see, replacements are ~$90 USD to completely replace all cutters on the head. This would mean 3 of the 4 edges from a 2 pack set for ~$90 would be used in the first side. That means you would have 2 2/3 sides remaining between sharpenings. I know its a ton of doe to throw down, but for people like me that plane by the trailer load, its gonna save a ton once I can come up with the cash to get the upgrade. Is it worth it or am I missing something?

Bellevue Woodshop After both edges were sharpened, I took the burr off with the blade flat on the stone. Could take these further with a very fine diamond stone, but I don't think it's needed.

Phil Sale It's like getting them for half price, since they'll do at least twice the cutting :)

Jer's Woodshop No Chuck and no tracking, I'm using a 4k camera now :)

***** Ah, that explains it...thanks...

Omarateastwind Another concern is that a lot of blades are hardened but only at the edge. That way you get a very hard blade that holds an edge, but the whole thing isn't as susceptible to breaking. As you sharpen the blade, you are removing this hardened edge and eventually you will be left with nothing but soft steel.

No it was yellow poupon.

Froma tron Filler? Even when I first started making videos there wasn't any filler.
