Take a good look there...

Do you know what that means?

Yes, I finally received the long-awaited new axes!

The supplier is two weeks late, and so am I, because I sent you the deadline he told me directly − I was stupid.

Good. Now the axles are there, that's the main thing.

That was the good news. Suffice to say, the sequel is less funny.

where it gets stuck

I was a little too rushed to quickly settle this problem of axles and bearings. I had planned to do a slightly tight fit on the axle. But I was wrong about the tolerances.

For Experts : I thought of doing H6m6, except that in fact the bore of the bearings were in M6 and not H6. So, I ended up with M6m6. It would have taken M6h6 or M6j6.

For the less expert: the shaft diameter is a few micrometers too big (1um = 0,001mm). You have to force it in − it deforms the bearing which suddenly no longer rolls well.

And now ?

I have two choices:

– Either have the shafts rectified. That's the real technical term. This means removing the few extra micrometers using a grinding machine.

– Either rebuild everything if they cannot be rectified.

Concretely, I was supposed to go to PACS tomorrow then leave for a few days in " honeymoon – something planned for a long time given the delays of the TGI. So I'm going to have to find a romantic moment between signing the paper and going on vacation to take care of these axes. I know a lady who will appreciate it. It's nice, entrepreneurship 🙂

So: I launch the rectification, and I disappear for a week. It will take at least that to recover a little. This kind of adventure weighs on morale.

Meanwhile, the factory is starting to work so that we have these damn axles very quickly. I don't know yet how long it will take them.
