399 forum posts 167 photos | Hello, These were bought a few years ago at stationary engine rally. However they turned out to be bigger than the ones used I use on my lathe, they looked the same at the time! Can anyone suggest what size or type they are? Thanks Peter

399 forum posts 167 photos | Hi Bill & John, Thanks for your help. It looks like it is bigger than an S4 (147mm) as its 160mm long but the tool appature is right at 38mm. The S5 looks like it has a tool appature of 44mm from the lathes data. None of the data found so far gives the "V" locating dimentions that go onto the tool post. Wondered if it was an S4 with a slightly longer body? Wondered if anyone had an S4 to measure the fitting dimention? Peter |
