RE: Making a threading dial - Mayhem - 09-05-2012 The angle is there Steve, as is the angle cut into the gear teeth. I was surprised myself, as I think this is the first time I have gotten down to eyeball it. This lathe was built (from best estimates) between 1890 and 1910. Most likely here in Western Australia by one of the larger mining companies. So there is no telling what the original gear looked like or whether the whole dial was an add on. Didn't they use a chalk mark back then? I keep meaning to sit down and document the journey from when I found her to what she is now but I haven't found the time yet.

Sounds like the inception of reverse engineering. |
