Balls are no problem. Easy to find on ebay. Usually sold in different sizes in packets of 10 or so, all for pennies, free shipping from China or Hong Kong. As for tiny springs, I don't know. Maybe also available from the same chinese sources? _________________ my flickr stream |

I could use a source for small springs as well. I'm missing one that's about 2mm in diameter and about 4mm long that is used to engage the slow speed escapement on my Pentax MX. Without the spring, I don't have speeds slower than 1/15. _________________ Michael

I was also looking for some. My plan is to try McMaster-Carr (in USA, https://www.mcmaster.com/#compression-springs/=17b8bxn), since they seem to have some that can compress to around 2mm which might be enough or it might be possible to shorten them.
If a vendor like that doesn't cut it, you might want to look into making your own. I found this introduction video pretty useful: https://www.youtube.com/watch?v=jAawhg6JtyY |
