If you have ever tried to remove the screws holding the blades in a SS jointer or planer (I have) there is no need for "lock" washers. The screws are tight as He**.

So they would seem to be a worthy addition then?

very true, however many tightly fitted bolts and screws don't always stay that way under use. the forces generated by that machine are intense. Case in point, no matter how tightly you lace your shoes, they manage to need re-tying part way up the mountain.jsburger wrote: Fri Jul 25, 2025 9:36 pm If you have ever tried to remove the screws holding the blades in a SS jointer or planer (I have) there is no need for "lock" washers.

One of the last things I'd want, is one of those screws ejected at operating speed

ayatollahgondola,
You said,
You can choose to go ahead and put the Jointer Knives back in without washers under the screws or find replacements.
For general information.
I checked my Jointers yesterday afternoon for washers. My 1953 Model 4E Jointer does not have washers. My 1979 Model 505681 Jointer does have the washers. My 1998 Model 555483 Jointer "C" does not have the washers. I didn't check my other Model 4E Jointer which is disassembled awaiting restoration.
Below is a picture of the screw and washer from the 1979 Jointer. As you can see the washer is a flat washer with an outer diameter slightly smaller than the Cap Screw Head.

.
Two other Jointers I have owned and restored include a very early 1954 Magna Model 620 Jointer which was missing 2 of 3 wedges, all 9 Blade Lock Screws, didn't have any washers and all 6 knife leveling screws from the Cutter Head. Because most of the Cutter Head parts were missing, I don't know if it originally came with those washers but according to the Owner's Guide it should have. Of possible interest, that Jointer happens to have the lowest serial number I have seen for the Model 620 Jointer. It is less than 500 higher than the highest Model 4E Jointer serial number I have seen. It is possible it was made before the end of 1953.
The other one I had previously owned is a 1960 Magna Jointer Model Number 620-C – Goldie. I don't remember if it had the washers, but it should have had them.
Both of these were restored around eight years ago and resold.
You said,
I understand your concern, but it is very unlikely to happen. It is a good idea to check the screws periodically. If one happened to come out during operation the guards would keep it from flying up out of the Jointer.One of the last things I'd want, is one of those screws ejected at operating speed
