How to Tighten Cannon Pinion so Pocket Watch Hands Work (with Watchmakers Staking Tool)

We're going to be going over how to use our Staking Tool Set to tighten up these three different types of Canon pinions. One of the obvious signs of a loose cannon pinion is - it's really EASY to pull off the center post. It should have a lot of tension or friction, so you can't pull it off so easy like that. Since your watch hands attached to the cannon pinion, a loose cannon pinion can cause several problems. One problem could be that your hour hand moves, but your minute hand doesn't move. Another problem you could have is your watch is running and it's winding and setting satisfactory, but the hands don't move at all. So it needs a good TIGHT fit on that Center Post so that it turns along with this post, so that your HOUR hand and your MINUTE hand (that are attached to the pinion) turn too! (Like THESE watch hands that are connected to the canyon pinion are doing here.) I'm going to get started with the stumps and the punches that we'll be using to tighten up these Cannon pinions. Now this stump is called a "crotch stump" and this is the only stump we'll be using today. You'll notice it has a little v slot in the center of it. Now if you go to my channel page you'll find a whole playlist of videos that are really organized. You can easily find different videos on staking tools and watch repair and other videos related to pocket watches. One of the punches we'll be using is named the "peen
punch". Now for this one special Canon opinion I'll be doing, I'll be using this special punch it's called a "roller closing punch" - a four-sided roller closing
punch. Also I'll be using this tapered shaft as a handle. I'll slide my cannon pinions on it and that way I can maneuver them around as I'm working on them with the staking tool set. So first we're going to center our Die plate up with our "centering punch". That's all this punch is used for - is to center up your Die Plate - and that way we get everything in alignment. Now we can put our stump that we're going to be using in the Die Plate.
We're going to start on our first cannon pinion. Now this style of Cannon pinion is the most common you'll see on some of the older 18 size pocket watches. It's a full tube style Cannon pinion. Now you see how I use that tapered shaft. I use it as a handle and it helps me hold that Cannon pinion so I can work on it. Now I'll be using this "peen punch" to make an indention on this Cannon
pinion. Now I take the Cannon pinion and rest it in the center of that stump that I'm using. Here it is from a different angle, so you can see a little bit better how it rests in the center of that stump - in that v slot. So we take the peen punch and rest it on the Cannon pinion and with a few light taps with my 3 oz brass hammer, it leaves a small indention, which in turn tightens up the cannon pinion. Now we should have a good friction fit with our Cannon pinion on our Center wheel arbor. Our next Canon pinion we'll be working on is a little different. It's a "split tube" Cannon pinion. You find this style on most of your LATER year pocket watches. We'll be tightening this one down about the same way we did the other one. The only difference is we'll be peening down that piece of metal that's on the
top. There it is -a tightened down Cannon
pinion!
