Hi,

I have the Porter Cable 6” benchtop jointer. I’ve never sharpened the knives and now I am getting uneven cutting on my workpieces—when I make a bunch of passes part of the piece is cut deeper than the rest. I’m going to check to make sure the fence is 90 to the table but I figure it’s time to sharpen the blades.

I’d really like to try to sharpen them in place since I hear it can be a pain to get them setup right again. Anyone have a good (read: not too complicated) method for sharpening in place? Any jig I can buy that makes it easy? I’m a novice so making complicated jigs probably wont work.

I came across this video on youtube: https://www.youtube.com/watch?v=AN9cE5aNCFo it looks like he is using a jig.

Any advice is appreciated.

Thanks,

Nathan

I do believe they have to be machined ground. Setting them is fairly easy with a couple magnetic based torpedo levels. I do more edge jointing then flat/face, so I keep moving my fence in and out to get equal wear on my blades.

I replaced mine on my Grizzly for the first time last month. I set them without a jig just a piece of al bar stock. They are now set better than they came from the factory. You shouldn’t be scared to maintain your machine. An unmaintained machine is unsafe.

+1 conifer. When doing edge jointing I move my fence in order not to wear any one spot on the knives.

You’re better off just buying new blades when you compare the cost of resharpening.

Don’t try to do them yourself.

Resetting the blades is not that difficult follow the manufacturer’s instructions.
A magnetic jig is very hand.

I have a very simple jig to sharpen mine. If you want, PM me and I’ll send you some pictures of it. It is basically a 2×4 with two 45 degrees angel cuts on each sides. I put the blades in and use a diamond sharpener on top.

Just replace them. New blades are often less than the resharpening fee.
I used a Snapcheck digtal gauge last time I replaced mine. It kept everything within .002” of the outfeed table. It is a pain though. I think when they are dull again I will get the Shelix head.

I dont know where you live, here in WI they charge .10-.15 and inch so for a 3 blade 6” jointer at .15 an inch, thats just less then 10$, thats what I pay.

Thanks for the advice. It sounds like replacing the blades is the way to go. I found these on Amazon the match the model I have:

http://www.amazon.com/POWERTEC-148015-6-Inch-Jointer-PC160JT/dp/B005NYXS5W/ref=pd_sim_sbs_201_1?ie=UTF8&dpID=41i4bLoqWWL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=1XH2HWJY6MW3ZAZ279DK

They don’t look like they are awesome quality so if anyone has other suggestions? Also some folks made reference to a snapcheck digital gauge—any advice on how to get them installed? The Porter Cable manual has no instructions at all on how to remove and replace.

Thanks,

Nathan
