Looks like I'm getting my first straight knife jointer. What accessories do I need?

My 8” jointer has a segmented cutterhead so I’ve never had to change knives and I’m going to be getting a 20” jointer and it a traditional 4 knife cutterhead and has 3 sets of knives that came with it. I would rather use what it came with and then worry about putting a Byrd head on it later if the straight knives aren’t satisfactory.

What kind of accessories do I need for it? Any special jigs for setting the knives in place?
I have a dial gauge but not one with a magnetic base. Is that something else I should be looking at?

Any help is appreciated.

You can use Planer Pals to set the knives, then
set the tables in relation to the cutterhead.

I highly recommend the Oneway Multi Gauge for setting knives. The planer pals will get you close, but the one way lets you dial it in to .001”. You will see that as you tighten the jib screws to the cutter head the knives tend to me a few thousandths during the process. With the Oneway Multi Gauge, you can see exactly how much the blads moves while tightening and you can adjust for that movement.

After doing my dinky 6” jointer a couple times, and my 15” jet jointer a couple times, and my 8” jointer a couple times… you can’t beat a magnetic dial indicator. For one, it’s no frills straight to the point time honored precision. 2nd, multiple uses thru the shop for other things (table saw, drill press, etc). Sure other special $100 jigs will get the job done too. But can you use that jig on other machines? Would rather use that $100 for more router bits or clamps or vodka.

On the dial indicator, the one I have has a rounded point. Does that ever get to be a problem trying to center that on a sharp edged knife? Does it take a bit of work to make sure it’s centered correctly on the point to make sure there is not a small difference in the reading when moving it from one side of the knife to the other?

The best tip for setting straight jointer knives is called a button contact point.You can get one from mcmastercar for a couple dollars.
Bob Vaughn has a very good video that will get you pointed in the right direction.
If you have trouble let us know many of us have very good techniques and we can help you find yours.
Here’s what the tip looks like.

I’m happy with my SnapCheck from igaging.com. It’s a cheaper alternative to Oneway at about $20. The handle is cheap plastic, but the magnets keep it flat to the table.

Yep, a Jointer Pal and a SnapCheck will get it dialed in just fine. The Snapcheck is very reasonably priced, and I found mine at http://www.chipsfly.com

Dial indicator, no question. Get one of the sets that has multiple tips so you have a flat one like Aj2 pointed out. They are pretty reasonable, $30 or so for a complete setup (indicator, mag base, 20+ different tips, and a nice case to hold everything:


(click on image for an example sold on Amazon)

In addition to setting knives, you will constantly be finding new uses for it that you never even thought about.

One ‘tip’ though (pun intended)... those tips are not machined to close tolerances and can have some rough edges or machining marks that will mess with the accuracy. A little sanding and polishing might be needed on some to make them perfect, but that’s a quick and easy task.

Cheers,
Brad
