digging a grave for the digger

nah... i see now aftrer looking at that pic magnified, it must have slipped when i ws tightening the screws, it still held the paper so i assumed it was good, thats a major gap there tho, so I'm feeling much less defensiveness and much more chagrin
fml i hate messing up soomething SO easy..... ugh so angry at myself now lol

I'll get a shovel.

I'll grab the fire extinguisher!

I'll grab a beer!

i used the paper method to set the mesh, its set the same way with every other one I've done, it was tight with a little wiggle, i think it could possibly have been the age of the gear it was around 25 years old, but the mesh was good

Was is the key word here. The motor must have slipped. I can see the wear, and I can see the mesh. The mesh is very loose. You see the lower area of the spur teeth?

This area is undamaged. So your motor had to have moved at some point, because this area of the gear still looks new, as seen by the nice molded in radiused edge on the teeth.

Shift happens!!!
It was only a spur gear... I've seen you break so much worse!

what had happened wuz..... i saw something shiny as i was tightening the screws, and there was a dog barking at the sun in the middle of the night, so when the northern wind blew in from the west it must have moved the motor... mhm yup gotta be it


the vomit was on myslef btw nopt you brotherman

It happens. Another thing, when tightening your motor screws, think about this... You have two screws on either side. When facing the screws, turning the one on the right has a tendency to lift the motor, loosening the mesh. Turning the one on the right has a tendency to lower the motor, tightening your mesh.

This is why, when tightening your motor screws, you should do it in stages. Loosely snug them down so you can still move the motor. Then little by little, going back and forth, slowly tighten them. I may go back and firth 10 times before I get a motor tightened, just to keep from moving the mesh.

I dontdo the paper method. Too loise for my tastes. I snug the motor then rock the spur. If I don't see movement, I loosen the mesh JUST TO THE POINT I see movement. You have to really focus. Once you see a slight movement of the spur, you're golden.

A dark force was at work. Look closer.

This is exactly what baboons would do to a lion cub, given the opportunity.

I vote @Doom!

Well in this case we know who the baboon was!

I don't wanna be the sacrifice again, last time it hurt!

Someone finally put to words exactly how I mess gears. I always get trashed for saying the paper method is too loose. But if you’re using a standard sheet of printer paper or even notebook paper, it sets the mesh way too loose for 32 pitch (and anything smaller).

Yeah, gears just need a tiny bit of air to breathe. You just don't want them pressing against each other. That builds up heat. Anything more than a very slight gap and you are no longer meshing on the intended contact patch of the teeth, which is basically centerline of the tooth (pitch diameter).

The paper method is ok. But it does introduce a bit too much play for me.

That thermal receipt paper that most businesses use nowadays is thin enough for getting good pinion/spur gear mesh if doing "paper method" on 48P gears and works very well on 32P gears, but taking your gear mesh to the next level of certainty...

Onion skin paper would likely be even thinner.

Rice paper (rolling papers) are already cut into handy, small size for ease of use, ultra thin and come in a dispenser thats small enough to fit in any tool box or road case.

I don't really use paper to set mesh much but I think a pack of zigzags might be a good solution for ppl who do.
