96 forum posts 24 photos | I used to have a problem with parting off on my Myford , I tried various parting tools, hss,carbide and a tipped parting system ,these all failed and through research and trial and error ,I found that the following all contributed too ' chatter ' spindle speed, width of parting tool, work piece support and lack of coolant. through my own experience the latter all helped , a low spindle speed ,a form of coolant ,I use wd40 on aluminium, a thin parting tool ie 1.5 mm ground from hss and locking the saddle and parting off as close too the chuck as possible all helped ,personally I found a rear tool post has to be the most effective way of parting off , also intermittent cutting causes bad chatter .

533 forum posts | Good point, Norman. If, like me, you do much smaller-scale work (O gauge loco building in my case) then one of these sets is the dog's b******s: - but see kit at bottom of next catalogue page (523C), for some reason I can't get the link to go there. Rather expensive, but if you look in th MSC monthly sales flyer they are often much reduced (£86 + VAT instead of £135 + VAT this month). For parting off thin-walled 2 mm brass tube there's nothing to beat it. David Edited By David Littlewood on 23/01/2013 12:35:25 |

3681 forum posts 70 photos | I part on my S7 usually dry and with a Q Cut type tool, just been cutting some MS round bar 200 - 400rpm, also some 3mm at 1000 rpm. What is the problem? I agree with David Littlewood, the Minithin system is also great, use it for e clip grooves and similar, made my own toolholders though. |

49 forum posts 9 photos | good news! was itching to try the new advice, so I went in the garage today to investigate this backgear thing....
undid the little screw and slid the piece back, and my back gear was spinning fine! By now I was already pleased with it |
