:D I had my ML7 re-wired and reversing switch fitted recently I mounted the Dewhurst switch to casting this morning works like a dream. Two mates did the lecy work. Here's the whole tale http://woolnwood.blogspot.com.au/2015/05/its-just-bump-to-left-and-bump-to-right.html Oh raising blocks of Jarrah t lift it 40mm so cables could fit. |

Glad things are running but why reverse a ML7 or a ML7 series? The odds are that the chucks, catchplate and faceplate might unscrew in reverse. No problem with collets and stuff secured through the spindle but I will NOT reverse my 3 phase motor otherwise. Again, people say that the old Dewhurst is regarded as electrically unsafe. Maybe others will be able to correct me. Mine is ready for the skip. Norman |

I ran my Boxford with a inverter This gives speed control & reverse Never seen the chuck come loose Did plenty of reversing cutting metric threads John |

I have to agree with you John, I've run in reverse quite a few times on my AUD with no problems. Graham |

Fortunately, screwcutting normally only uses slow spindle speeds and you're not cutting in reverse so there's little risk of the chuck unscrewing. We used to have a Simonet lathe at work with screw on chucks. The chuck backplates had 2 or 3 slot's milled within a mm or so of the bore and a clamping collar squoze (is there such a word?) the backplate to the register on the spindle. Cheers Phil. |
