Dave,any board that has a bend that is similar to a piece of sheet metal bent sharply in a tool for that purpose should
just be cut off before any facing is done.
I was flashing back to some of the used jointers I’ve seen. Mostly Craigslist ads.
Never assume the knives in a used jointer that hasn’t been set buy you are correct. I’ve seen knives too thick,too wide. And once I saw the gibs backwards.
I tested a jointer out in Oxnard once that had the tables so out of wack I almost got my self in some big trouble with a piece of hickory.
Im also guilty of jointing longer then needed boards for the simple pleasure of using my machine.
Good Luck

Bumbling forward into the unknown.
If you wish to understand safety, you will have to be very careful in how you interpret the information provided.
Some people don't use guards, some use all of the safety devices on the market, and swear that you are suicidal if you don't,
Some work with their fingers a fraction of an inch from the blades and are relaxed and comfortable, some quake in fear at the thought of being within a foot of the blade.
Maybe you should ask about the facts, the results, not the opinions.
Find out who had the most accidents, and under what conditions.
understand also that safety is a personal thing, not a statistic, Statistics are great for insurance purposes. If you are the one in a million that it happens to, it's very personal.
Study and understand you machine, tooling and materials, And you will work with confidence and control. Smooth, relaxed, but firm motions.
Develop process and procedures that work for you.
Have the discipline to follow them.
Don't follow others.
Understand Yourself, and the pressure to get stuff done, learn to know when to quit and pick it up tomorrow.
Learn to live in the second.
The only job that exists is the one that you are doing now.
Only when that one is done do you become aware of the next one.
Eventually there will be no more to do and you will be finished.
If you think ahead you will not be concentrating on what you are doing.
Safety is in your control.
I have a 12" Invicta jointer with Byrd head. When face jointing I usually use a home made hooked push block on the back end of the board, and a rubber grout float for the front push block. Rubber grout floats are cheap and grip the wood very well. When I am face jointing a lot of longer stock I swing the power feeder around and set it up. It makes things a lot faster and safer.
Good thread. None of us is so experienced to not benefit from a safety refresher. The jointer is a deceptive machine from a safety standpoint, not as obviously menacing as a table saw or spindle shaper. I once had a guy tell me a table saw can cut your finger or hand off, but a jointer will turn it into scalloped potatoes.
The only two practices I can add/echo to what we've heard here already;
1. Pay attention, stay present in the moment. I happen to think lapse in concentration is the root of many workshop accidents. I don't think any manner of safety aids are a substitute for the operator's focus.
2. Try to hook your pinky finger over the top of the jointer fence, or top of the board when edge jointing. When your hand is hooked or anchored to something, whether the machine fence, or the workpiece, it's one line of defense to prevent it from flying into the cutter. I try to practice this at the miter saw, jointer, router table, everywhere I can. Learned it from a woodworking master who has all ten fingers, none shortened.

I just ran across a Craigslist posting that made me think of this thread. The last sentence reads "This jointer has severed me well".
