--- Quote from: bogstandard on September 22, 2009, 04:48:54 PM ---You've just reminded me John, so I have popped out to the shop and got my notes. Readings when I checked my lathe for doing imperial threading. I decided to check using the 16 TPI I already had set up. Which should give 0.0625" movement per revolution. No of turns on chuck Saddle movement 2 0.124" 4 0.249" 8 0.498" 16 0.998" 24 1.498" 32 1.998" 40 2.498" 48 2.998" So it looks like there was a minute amount of backlash to take up at the beginning, then after that, everything was absolutely perfect. So now I know that at least I can cut 16 TPI and know it is correct. I think I will do a few more different settings, just to see if it is still as accurate. John --- End quote --- magic. piece of mind for when you come to do any other imperial work. John S. |
