Rolex 2236 winding in a mainspring Flared end no hole

[quantieme]

Hi All, just gone to wind in the mainspring on this Rolex  cal 2236 to find that it does not have a hole but instead is flared on the end to sit in the flared part of the arbor. Does anyone know if there is a winder on the market for this as although I have not tried yet I am assuming that my standard winder will not work in this case. thanks. Any help or advice appreciated.

I have seen that some sellers on Ebay are selling mainsprings that they say are for 2235 and 2236 so again I am assuming the 2235 uses the same spring and Cousins sell a winder for the 2235  so would I be correct in assuming it would fit the 2236 does anyone know.

well after some research I have found out that this is a non serviceable part, because of the flared design, you have to buy the whole barrel complete.

And do You like it, do You intend to byu new barrel and give up assembling what You have?

I'd think it's worth trying to re-firt the spring in the barrel by hand; it's it otherwise going to be replaced you have nothing to loose!

I've managed it a couple of times, where I have not had a suitable winder.

yes, I bought a new barrel, it comes complete with the spring, arbor and lid as the original is a non serviceable item. Out of interest i tried winding the old one in by hand but it was very hard and it bent slightly so I would'nt recommend it.

I did try winding it in by hand just to see if it was possible but i ended up bending it slightly, i bought a new barrel complete which was a lot easier lol.
