Hi Duncan, welcome aboard.
I love the wooden frame that you have made for driving the turns an rather stylish piece of micro turning. You are obviously a craftsman with stylish artistic flair, and I look forward to seeing more of your endeavours in the future.
Hi, welcome and all good wishes. I gave all that gear away years ago that was left to me as I will not get into that depth of work !. Nice bit of turning. If I cannot obtain an essential spare part the job does not get done. Best regards, Mike the Jobber.
Hi @StuartBaker104 - you've obviously done your bronze research but just thought I'd add in something for consideration...
I know you're looking at phosphor bronzes in the main but there are also silicon bronzes. A good overview here ... https://www.avivametals.com/collections/silicon-bronze ... mentions "offers added strength in conjunction with the self-lubricity of silicon for excellent bearing and load properties". Handily, because silicon bronze is used for brazing, then rods of 1.6mm and 1.0mm OD can be sourced ... just the OD dimensions you need.
