4 forum posts | A new member. I have recently purchased a Myford 10. I have found two new parts but sold for Myford 7. Both are massively cheaper than parts sold for Myford 10. Could anyone tell me if they would fit my machine or they they could be modified to fit? I am looking at a travelling steady and a quick change tool post. Can anyone help please? Thank you |

1297 forum posts 50 photos | Sorry, but both the travelling steady and the QCTP are different, and unique to both machines. As you say both are much more expensive for the ML10, largely dictated by their relative rarity compared to the ML/S7 versions. |

467 forum posts 60 photos | David, I find it difficult to believe that there is a significant difference for the steady. Myford ML10 is 3 3/8" centre height versus 3 1/2" for the ML7 and both look like they use a 'T' bolt fixing to the cross slide. What am I missing? I can't comment on the QCTP because I've never used them. Phil H |

Phil On a pure point of accuracy, the ML10 is 3.25" centre, not 3 3/8 The clamping flange is different on the 7 and 10 travelling steady castings - and if one would fit the other, I can't see why Myford would have gone to the trouble of casting a new travelling steady for the ML10 when it was introduced in 1968, if the steady for the 7/S7 that had been around for 20 years before it would fit

467 forum posts 60 photos | I agree with ega. Make your own or modify the ML7 steady. David, you are right - 3.25" rather than 3 3/8" sorry. Phil H |

1817 forum posts 2 photos | I am a touch puzzled by the quick change toolpost. Are we talking about the Dickson type or the Myford boat type holder? If it is the Dickson type, then I have one each of the Myford Dickson QCTP on an ML7 and ML10. The ones I have were recently manufactured by a guy who used to make them for Myford. The only snag is that if using a Myford QCTP on the ML10, then you are restricted to using tooling which is 6mm square, unless you mill a bit off the bottom of the tool holders. The ML7 can use 10mm square tools, maybe a touch more. Andrew. |

1297 forum posts 50 photos | Andrew The boat type holder would be a 4 way holder, and not a QCTP, would it not, so I assumed (dangerous, I know) that Graham is referring to the latter, the Dickson type. I believe the Myford QCTP is a different one for the 7 and 10, as original equipment. Certainly 'new' Myford list the current QCTP as fitting the 7/S7 and 254, but NOT the ML10. Whilst they are physically interchangeable, I am not sure they are the same height, and thus cause the problems you mention. The rear toolpost is different from the 7/S7 amd ML10 too.

David, Not important I know but looks like we were both wrong. Myford information says 3 5/16" centre height. Phil H |

1504 forum posts 142 photos | David, Phil H, I don't want to start a pedantry competition, but the drawing in my ML10 manual shows 3.25" This is a 2010 issue. See lathe number at bottom of page - maybe earlier ones were different. Excuse it being a bit askew.

467 forum posts 60 photos | I wont bother to scan the information but mine was bought in about 1982ish. Perhaps they changed later on. My information definitely says 3 5/16".

4 forum posts | Thank you for the information. Has anyone tried the Chinese quick change tool posts which seem to be aluminium? Seems soft to me for a tool post. Can anyone tell me why the Myford 10 travelling tool post is canted over whereas the Myford 7 is straight? Does anyone know what the difference is between the two machines regarding the fixing point for the travelling steady? Thank you |

467 forum posts 60 photos | Graham, Once again, I can't answer any questions on the tool posts and unfortunately, I am only able to partially answer your steady questions Perhaps somebody with an ML7 travelling steady would be kind enough to help out. I have easy access to a Myford Suoer 7 lathe and a Myford ML10 travelling steady but frustratingly, I don't have an ML7 travelling steady. With the limited view that I have, it looks like the steady for both machines are fixed in exactly the same way because the ML10 travelling steady will fit the Myford Super 7 (but with the difference in the centre height of course). The steady base has two machined pads with a recess between them (presumably to ensure positive contact via the two pads onto the flat surface of the saddle - I will take a photo for you). It has a hexagonal head screw to hold the steady down to a tapped hold in the saddle. The holes must be the same on both machines. The canting of the steady obviously takes the steady contact pads back towards the tailstock end and the joggle is sufficient to prevent contact with the cross slide. Why the joggle? I can only assume that it helps the steady and toolpost get closer to the headstock end to improve its useful range. The ML7 has a gap in the bed and hence, a different geometry. Its saddle stops before the spindle nose - I can only assume that the ML10 saddle can get a bit closer to its nose - hence a joggle on its steady. Sorry the answer is incomplete but it might get you slightly closer to a decision. Phil H |
