Lubricant for small movement

Question

Hi everyone. I've been fiddling with several small movement. φ15~20mm The puzzle is such I always use HP1300 to oil the second and the third wheel. Sometimes I thought HP1300 maybe too thick for those slow movements. They have lower friction and smaller pivots. I already swap 9010 to oil the third wheel. What if I use 9010 to oil the second wheel as well. Will I gain or lose performence? Thank you!

The Mobeius list below points out the viscosity so should help you decide on the best course of action to take.  One would assume lighter movements require lighter lubricants but the forces they endure are the same.

I think the lubrication scheme would be almost the same down to a certain size, I seldom work on watches smaller than 7 ¾´´´ nowadays and in that size I use the same lubricats as I would on a regular 11 l½ ‴. 
Just so one get a sense of size difference I took a pic. A 2824-2 vs 2671

So 2824-2 tech sheet with lubrication recomendations

And the 2671 tech sheet.

I don't know. I don't have 9020. But what I'm thinking is HP500 and something like that. Honestly I don't know much about lubricant

most common choice for lubrication is Moebius which can be found at the link below. They even have a lubrication chart you can download to add to the confusion and a lot of tech sheets where you get some of the specifications.. iin the absence of any real specifications usually what everyone goes by is viscosity.. Lighter oils for fast moving parts heavier oils for slow moving parts..

typically I work on pocket watches this means the lightest oil on my bench is 9020  I use it almost everything except the really heavy stuff like center wheel HP 1300..

    • I think that a rolling fixture is useful only when making the blade from a blank. Othewise two strokes per side on an aluminum oxide do for me. I let the flat guide itself  and slide in one direction only. . Of course the smaller the driver the less tactile feedback.I hqve one screwdriver holder with an embedded oxide strip and find it extremely handy. 
    • Hi Just out of interest, was the broken part of the balance in the packet with the roller and the rest of the balance.   cheers  
    • Hi John and welcome to the happy factory
    • Even though your package is opened I don't suppose you get a picture of the bits and pieces of the package for us? Then a caution factory packages or basically the paper envelopes that typically watch parts come in except balance completes usually come in very special packages but any of the paper envelopes always require caution because it's standard operating practice for a lot watchmakers to put the old part back in the package.  Often times they didn't label that it's the used parts sometimes they do.
    • Hi all, Hopefully I'm on the right forum this time!  Thought while I was struggling getting my first project back together, I would try a pocket watch as I'd read they were a bit easier, so I bought this off Ebay. I've fallen at the first hurdle as I can't work out how to get the back off! Don't think it screws off, as I've tried without success, so thought it must prise off, but again no luck. I don't want to apply too much force, just in case it actually does screw off. Anyone any experience/thoughts on this please.
