26mm Spring Pin Hack

[rmcsherry]

Thanks for sharing this, I've now got a set of 20mm spring bars and some spare tubes on the way!

Hmm, don't really see the way of securing that springbar's pin against the wider lug hole (non threaded one)?
That's the standard springbar you supplied the link to above, its pin-ends are simply too thing for panerai lug holes and will shot thru

cheers,

Those are,i believe,the single shouder spring bars. Pardon my ignorance,but is there a particular Panerai which does not have threaded lug holes. I am wearing my Fiddy right now and it looks as if they may work just fine. All they have to do is "snap" on either side to hold the strap. No chance of "shooting through". :wink:

The problem with these, [types] is they are made for strap buckless or conventional watches, they are too small in diameter. These aren't even 'single shoulder' pins so they'd probably rattle around and fall out. (At 1.80mm the overall pin here is about the size of Piano wire I was using, and then it gradutes smaller on both ends.)

I am talking about spring pins that are in result, near as strong as the lugs they are attached to. No worry about failure or breakage ... conventional hollow spring pins are generally made of brass or soft steel and can be broken merely by pulling on them. This spring pin hack is based on Milspec solid lug pins which are used for strength and anti-failure risk. I prefer to drift them however to allow for strap changes - the downside on solid lugs is generally they are splined or sweated in permantly.

This modification is two-part. One it "looks" like the originals, and two, it's actually functional. The current available retail, single shoulder Swiss made spring pins are just too small. The end pins are too small a diameter and so while they will work, they don't look good at all. I will add some images showing them next to these hand-made variations ..

(easier, would be leave the original REP screw end pins in, that takes no effort and no costs!)

Understood. :wink: Now i see what you are trying to acheive.
