Let down key info needed

[namonllor1953]

Hi Guys,
As you know, I pretty much have been making most of my handtools. Well, with that in mind, I’d like to make a set of Pocket Watch let down keys like those that Bob uses on his first watch video. Problem is, I don’t know what the measurements would be for the square tips. If some one would be kind enough to mic their set and post it for me, I would deeply appreciate it.
Thank you,
Ren
P.S. I did look fora set on Google but all I got were the hollow keys and not the square tipped ones I seek.

Hey Ren, Only if you post what you come up with I have several sets and there are a few extra measurements than you would need for a decent set of 3 double end let down tools. I dont think you have to be exact in the dimensions. could be some of these are worn a bit? One of my sets are #s 1,2,3,5,7,9.
1)1.55mm
2)1.30mm
3)1.20mm
4)1.17mm
5)1.07mm
6).98mm
7).95mm
.87mm
9).80mm
10).75mm
11).60mm
Uh Oh looks like I missed one in there 🙄 , I think it will be o.k though. William
