Hi Chris They will probably have a slight chamfer on the ends ,,,, :thumbup: Any way what you making :poke: :poke: :poke: ,,,,,,,,,musical box ? Rob |

:( :( :( Money was refunded this morning with a phone call telling me that all lengths of the 1/32" are discontinued :( Looks like I`m back onto cutting them from 1/32" silver steel. Hopefully my order from College Engineering Supplies will be here this weekend, I`ve been waiting nearly a week now. Rob - I`m back onto my very first original project I ever picked in 2004 when I purchased a Unimat 3 at university. (stupidly with no experience back then) . I`m building Dr Woodwards Gearless Clock - designed and build write up by Wilding: I`ll start my project log soon with more details. I`m pretty crystal clear with how it all runs now, just need to figure out the maintaining works but I think that`ll become more obvious once the motion works/main train is together. Anyway, back on topic. ... :( :( about the dowel pins, what a cracking buy they would have been. Absolutely spot on!! I`m basically trying to make them from silver steel. Chris |

Smallest I can find from other suppliers is 1/16 ... looks like that idea is now washed away, nay mind! |

Chris, Is this the escapement you are building? http://www.angelfire.com/ut/horology/bpinwhl.html Joe |

Hi Joe, sorry, never replied. By now you have probably seen my Dr Woodwards Gearless clock thread, so no, your escapement shows a pin wheel escapement. Mine is an escapement using a pin wheel but using a gated detent, so no really as shown in the image. Regarding digging this thread back up to the top, I`ve had a horrific weekend trying to cut these pins! You don`t appreciate how thin 1/32" until you see the steel wire. I setup my dremel which cut the steel OK, but I couldn`t get the disk to cut near enough to any sort of jig I was holding the wire in. The only method that worked involved me chucking the wire up to lightly file the taper and then chucking the wire back up, setting the jig to put the wire to the right length, cutting the pin with the dremel and then re-chucking the wire to file the sharp edge made by the dremel. It took me nearly 4-8 minutes a pin. Now I know I need more patience, but that was taking the biscuit to do all 60 pins! I tried parting with a stop held in the tailstock for length and the cut was so messy that even right up to the chuck I was bending the wire a little. I could have used a split collet but it wasn`t worth wasting more time in another method I thought wasn`t going to work. Anyway, I spent last night building a pin punch as suggested on the Gadget Builder website.... I hope that works OK !! I didn`t get chance to try it before bed!! |
