How To make A Clock Part 11 - Making, Polishing And Bluing The Bezel Screws

8/3/2015

Its surprising how much of the time required for clockmaking is spent making screws! They're such a small, apparently insignificant part, yet they require a surprisingly large number of operations to complete.

In this video, I go through all of the steps to make a hardened, and tempered screw, focusing on the 4 screws required to fasten the chapter ring inside the bezel.

Be sure to watch the companion Spare Parts video: Drilling And Tapping A Small Blind Hole.

Hugs from Brazil. Very nice job, with skills and pacience. But what kind of brass do you use? Thank you.

Hi there Julio,

I use a free machining leaded brass (approx 3%) for the rod stock, and what is called "engravers brass" for the sheet stock. Its a leaded brass too but it has a half or full hard temper.

Metal specifications vary across the globe, and it is a little difficult to pull it all together to be sure of what you are buying locally. For reference in the UK, the rod stock is referred to as CZ121 and the sheet stock as CZ121 (with a hard temper).

Confirm your local stock to be consistent with that, and you're good to go.

Cheers,
Chris.

What alloy steel did you use? That's a truly beautiful blue you're getting. You mention alloy matters (in some video) but don't say which you're using here.
Thumbs up in general and may you have every success! I've been enjoying your work and thanks for sharing.
