We discussed this before, no? You could use the flat punch to flatten and slightly tighten the hole in the rotor such that the axle (=shaft?) will hold in place. That looks very pretty! Nice job.

Does the tech sheet tell you how to remove the stem?

If you would: please. I have a Favorite staking/jewelling set, but that uses 8 and 4,7mm tools. Yours might be different.

Only harden after you have the shape and cutting faces 95% of the way to sharp, So yes! what I do is as follows: -Shape my cutter to the desired rake and relief, then sharpen the cutting face and relief faces to something that would cut brass. -Heat to a cherry red and hold at the temp depending on thickness of material. A 1/8in graver I would hold there for 30-45 seconds. -Immediately plunge into oil and swirl to maximize heat loss -Stone all faces of the cutter back to a nice finish with 3K oil stone, including the cutting face and relief faces -Temper with a torch to a light straw color only to about an inch from the cutting edge, this happens quickly if you arent paying attention and is why we want to stone to a nice finish before hand, so we can easily see the change -Let air cool after it has reached a straw color for a few seconds, then plunge into water or oil, doesn't matter at this point -Stone on a fine oil stone, I use a ruby stone, and it gets me a mirror finish.
