As usual you’ve got it down pat Gary. If it’s in a person’s budget I say avoid this all together with a spiral head jointer.

Great design on the jig and head setting trick.

GaryK,

Nice tutorial. You make it look so simple. Good job!

Could you stop by my shop and give a demonstration (that is, the next time I need to reset/sharpen/change blades). Lol.

Thanks for posting this. I need to calibrate/setup a jointer that I recently purchased and your jig/instructable is “Just what the Doctor ordered”.

I have watched videos, and read descriptions on setting jointer knives, and wondered why most of these people don’t lock the cutter head in position.
You mentioned using a wedge, which is the way I have always done it.
I didn’t see the wedge in your pictures, I put mine in front.
When I’m done the small wedge and the rest of the tools, for setting the knifes, are put away in one spot for the next time
Great little jig set.
I was going to buy some of those little magnets, for other things, but the shipping was as much as the magnets.
I never thought about the hobby store, great idea, there is one close by, I have been to, and they probably have those little magnets, so I will go check it out. Thanks

Changing jointer blades is a tedious job and I like your ideas. But I’m confused as to why you would want to be 1-2 thousands of an inch higher. I’ve always set them to the same height as my out feed table. Whats the benefit of going higher? It just makes sense to me to keep them at the same height.

bubinga – You don’t see the wedge because I wasn’t actually changing the blades at this time. Just taking pictures.

ScottN – I have found that when setting it exactly flush, I “bump” into the outfeed table sometimes. The extra difference assures that I never do. It has no affect on the jointing operation. Plus it makes the find top center a little easier having something to work with.

Magic !

So … do I have this right ? ISTR hearing/reading that … with metal (like the straight edge) ... you have to be REALLY careful not to nick the blades, during this sort of process.

Are they truly THAT soft/fragile ?

Not a thread-jack. Just a question about this brilliant, and near dummy-proof method :-)

The problem I had when installing my last set of knives was that the blades rose slightly when I tightened the screws down.

Not sure how wide your jointer is (mine is 8” and has 5 screws), but I will try this next time and see if it helps.

The Austrian Felder company have the easiest idea they have an inbuilt frame which comes out to fit the jointer knives when it’s returned it clicks into be locked at the correct height cannot be too high or low you can change knives in seconds as oposed to a long drawn out affair. Alistair

I have a question/observance. It was always my understanding that the outfeed table should be exactly the same height as the top-dead height of the blades. It seems to me that even at .002”, when the stock gets to the point when you would put downward pressure on the outfeed table, the stock would tip down on that side. I realize that the stock is probably flexing more than that but it seems it would also cause the jointed edge to be not quite perfectly straight. It would also seem to me that bumping into the outfeed table would indicate that the blades are set lower then the outfeed table.

D_Allen – Technically and theoretically you are correct.

The .002” won’t effect anything and just helps getting the part smoothly on the outfeed table.

Making a final pass with a perfectly sharp leading edge, I have found that any pressure on the end of the board will catch on the outfeed table.

I mainly do it for the first couple of passes when the lumber is not flat. It just gives it a little extra clearance.

I think the knives are that fragile Neil. Be careful to not nick them. That is the reason we are taught to not set our manual hand planes on their shoe. Instead we lay them on their sides.

Thank you Gary. Figuring out top dead center has baffled me, your method looks dead easy to do.
