Waltham 1899 17j won't wind fully keeps slipping

[BUSAKAZ]

Hi all, this is my first post so please be gentle, I can wind it up about 4 turns and then something slips and looses all its tension and I wind it again and it does the same thing, so I brought a new mainspring from cousins uk out of the GR book page 195 under 16s 1899 witch lists it as part no 6991-TR as a 0.19 thickness, in my E.& J. SWIGART CO book it lists it as 4 different sizes 0.19  0.18  0.17  0.16  0.15, when I put the new spring in it done the same thing so I striped it down again thinking winding pinion teeth and crown wheel are badly warn but they are not !!, so with the crown wheel removed I tried to wind it up with a screwdriver and it still slipped, so I tried to close the spring tighter you guessed it SNAP, so I got another one but an 0.18 thickness put it in and still the same so my question is what am I doing wrong ??? do I still need to squeeze it in or should it be ok straight out of the box.

Many thanks Kaz

what you have is a Waltham motor barrel, the problem is at the other end, the spring slips at the barrel hook.

The end of the spring must be shaped to match the barrel wall, some explanation here :

Thanks for the reply, this is a pic of the actual spring, it all looks spot on to me but I know nothing, do you mean bend it in a bit the last 5 mm ?, I can't see how it can jump out as it is hooked it and the more you wind it the tighter it becomes.

many thanks for your help Kaz

The problem is that the mainspring slips on the barrel wall ; not at the arbor

This is a picture from Chicago School ; look here, sec 171 :

It's really nice. How do you wind it? Where did you sourced the case?

I like these conversions. I know a lot of people feel they are a Frankenstein watch but in my opinion it's nothing different than putting a seagull movement in a aftermarket case and making your own dial. Hey, Tiffany never made their own watches. I think these watches allow people to wear a beautiful movement again. Im in the process of making one as well as a gift. Good luck your watch looks great

I drilled a hole in the side and put a stem in a pin vice and just wind it like a key wound pocket watch.(hunter movement)

the case I came across on eBay with some other stuff, I can't believe how accurate the watch keeps time.
