meyers no.58 Making Jaw Inserts for Meyer's No.58 Movement Holder

[Stagesmith]

I don't know why I was limited to a 3DPrinting forum, but oh well.

I managed to grab a much coveted Meyer's No.58 Movement holder off ebay, but it only came with the second to smallest jaw inserts.

Not to be detered I reverse engineered how to machine the jaw inserts.

I made a small insert set as a test and then made a set for size 16s pocket watches.

I'll make a few more to fill out the set.

I made these from Aluminum, but might try glass-filled Delrin as an experiment

The drawing could easily be used to design the jaw inserts for 3D printing in Nylon or a hard Urethane

I realize this sounds stupid, but what did you use and how did you make the cuts to partition then original round piece into the two sections?

Very cool.  I have a full set of the original jaws, which gives a lot of flexibility.  But I like that you came up with some extra designs.  You should consider selling sets of those. 

I was thinking of 3D printing some, if I had a movement that the existing jaws aren't suitable for.  I did have one movement where the jaws were pressing in on the teeth of the barrel, where a custom set of jaws would have been beneficial (maybe a straight wall instead of the sloped wall grabbing surface).

That’s some great work. I love my Meyers and I could have used the pocket watch holder last week. I don’t usually work on pw so I used the vise from my case back opener
