Re: Synchronome contacts pitted

Perspex works well and is easy to work.  It also looks almost indistinguishable from glass.  You can buy a rod of perspex very reasonably and make the rollers in a small lathe.  Glass is more difficult, but can be done.  I have not seen any for sale.

A supply for the glass rollers for the ‘back stop’ or detent that runs on the count wheel would be great. Has anyone any news on a source for them?  I think I recall Jan Wright produced some a few years ago and they all sold out like hot cakes. I am currently using a delrin one kindly made by a friend but I fancy glass would have the lowest friction in that application.

Hi, Naing,

There are reproduction gathering arms for sale right now on eBay for 25 US dollars plus a nominal shipping cost. Just enter the search term “Synchronome”. Making one would be an interesting challenge, but if you want one right now, here you go.
