Hi all- I’ve just had a couple very affordable Edge Finders for the Nomad ER-11 collets made. I started with a couple of sets of cheap wigglers <tinyurl.com/y82qmjkv> and had a local Cylindrical grinding service <fcjprecisiongrinding.co.uk> reduce the shaft diameter to 6 and 7mm, respectively. Tim did the job while I was waiting and charged me UK£ 15 /chuck. In total the edge finder cost me UK£ 20 and the total length is 82mm.
Best.
