![]() 6956 forum posts 229 photos | In this lull in the rain I went out to unwrap and re-oil a machine I have in storage and ended up taking a bit off it. So instead of sensibly using the engine crane and big trolley I messed around with ratchet straps and my smallest skate to get the dirty 200lb lump along and over the door threshold. Really should modify that door but now the lump is cosy and dry in the living room. (no 'lump' is not code for 'wife' you will be suprised to hear I am not married.) |

![]() 5068 forum posts 3 photos | Well attacked the tailstock this evening.
This is what took the time
That square block replaces the round keeper, it's bored the same size as the barrel, has a fixed key fitted and a lock.
These are the bits that go in.
On the left a dummy barrel, made out of stainless because I had it in the right size, keyway nearly to the end so it can slide thru the square keep block but not come out because of the key and bushed to take the screw shaft extension.
max usable travel. |

![]() 5068 forum posts 3 photos | John, Great minds ? Already worked out where I can get the two screws without being in plain sight, not that it matters, and miss the graduations. They are not that critical as I'm fitting one of the cheap linear scales with remote DRO to it. Got these on the other lathe and they work fine for what i do. I know you have a proper DRO on yours but for my work that's overkill.
I have posted this on the HSM forum as well and can't believe the number of replies I got saying just cut the tangs off ?
Hang on they fit one lathe, 20mm out on another and 1 1/8" on this one but alter the tooling to just fit one ? It already fits one. The fault is in the machines not the tooling.
Anyway I have now got, or will have shortly when I fix the linkage, an increase from 3" travel to nearly 6" and lever feed to boot without loosing the screw feed, AND the flat earth society will be pleased to know i haven't had to drill any holes in my machine.
That's a definite No- No, can't drill holes in your machine but it's Ok to chop the tangs off |

2032 forum posts 41 photos | I am no fan of butchery of machines but frankly if its yours make it work your way..especially if you can put it back the way you found it..nice work John. Ps (?) Does that make me a flat earther? |

![]() 6956 forum posts 229 photos | Nice mod JS. Unfortunately it shows why magazines are on the decline, a few pictures and anyone with half a brain can do it - who needs drawings or a long article. Can't understand the 'don't drill' attitude. The great thing about owning a Landrover is you find chopping great chunks out let alone a few holes is the norm while shineymobile owners worry about the slightest scuff from car park door opening clashes. |

![]() 5068 forum posts 3 photos | You would be surprised by how many that do need the article. I once posted something on the web that simple it was only about 4 tapped holes in a block of metal and a guy asked for drawings. When I pointed out that mine wouldn't fit his machine and to take the idea and run with it i was castigated for not being helpful.
You can't spend your life riding round Tesco's car park with L plates on, at some point you need to get out on the road.
As regards altering machines we all work differently and who says the manufacturer got it right in the first place ? Why did Myford make the 7 series carriage move 0.861" per hand wheel turn ? When with a bit of forethought it could have gone exactly 1" and no need for expensive, complex hand wheels to be offered as extras. But hey it's a Myford [ faces East, incanting 3 hail Mary's, 2 Moore and Wrights and a Mitutoyo ]

2032 forum posts 41 photos | It might be a matter of confidence. .if it can be unbolted and a new "better" one made , then there is no risk of wrecking your machine....if it requires sawing bits off..well you need to know you are right.... Cautious but not devout |

![]() 6956 forum posts 229 photos | I'd hazard a guess that it would invoke the same level of interest as the screwcutting clutch so might need drawings for up to a dozen popular lathes. JS shudders at the work involved but perhaps that is where MEW could employ a pro draughtsman. |

1058 forum posts 16 photos | Modified my Mk3 Worden &C grinder to give variable wheel head hight. Used some bits that were surplus to requirements for the Quorn. As it turns out the wheel centre to column centre distance is exactly the same as the Quorn wheelhead so that can be swapped onto the Worden should the need arise I plan to drill the column and mill a slot in similar to what has been done on the Quorn so that I can have a screw operated rise and fall. the wheelhead will also be keyed to the column to maintain registration of the wheel to the table. |

![]() 314 forum posts 44 photos | I came up with a ridiculously (to me) complicated arrangement to drill the steam passage on the S50 cylinder at an angle. According to Tubal Cain's article, that I'm following, the angle is about 14 degrees. So, not having an angle vice, I clamped the cylinder on an angle plate and rested this on a piece of 3/4" square bar that was clamped 3" from where the angle plate touched the table giving an angle of 14 degrees. Was quite pleased with the result although I haven't taken a pic of it. Before the final clamps were fitted. Final arrangement of clamps Gary |

![]() 19226 forum posts 749 photos 86 articles | Hi Gary, I still have the jig I made for my Stuart 10V.. it's a piece of wood with a 90-degree notch cut out of it at the appropriate angle This is one job where the cheap and cheerful angle vices everyone sells come into their own. I always eyeball the path of the drill before commiting - I haven't gone wrong, yet... Neil |
OuBallie | 18/02/2014 09:23:07 |
![]() 1181 forum posts 669 photos | With you there Neil. Every steam passage I've drilled has been done on the drilling machine, the angle gauged using Mk.1 eyeball and a normal vice to hold the cylinder blocks. Quick and easy. Geoff - Treatment caught up with me again, so incapable of doing much right now. Bummer! |

![]() 19226 forum posts 749 photos 86 articles | Well, last night I gave my workshop a deep clean(ish) in preparation for a distinguished visitor. All ready for battle to recommence on several projects... Today fixed a carpet cleaning machine. Series wound motor had some blown windings which had caused arcing at a circuit board. Ominous yellow flashes from within the machine followed by the circuit breaker going. Ther sparking had caused much tracking across the circuit board. Unlike a computerised washing machine board that died the same way, this one only has two diodes and a capacitor, plus a pair of connectors on it. Amazingly at up to £38 the most expensive is as much as the cheapest washing machine board - go figure? Apart from swapping the motors, all that was needed was getting all the carbon off the board to get the resitance between the mains terminals back over 200Mohms from 7kohms! Neil |
