Thread: Harrison Milling Machine Zaxis gib strips |
10/11/2018 11:18:57 |
Hi Andy, That's perfect thanks - now I know exactly what the parts list is saying (why Harrisons' thought that just listing some part numbers without showing a picture was O.K remains beyond me) I will turn up the necessary parts and incorporate then in my rebuild. Machine is now starting to look good again and I have got rid of all the looseness and slack and with the 'Z' axis finally incorporating the adjustment modifications and all the oil ways clear iof the old congealed grease everything runs very smoothly indeed. Thanks again for taking the time and trouble for sending me all the information and photos. Phil M |

Hello again Does anyone have any details or pictures of the later version of the vertical gib adjusters on this mill? I have the parts list but it says that "later models had their gib adjusters modified" It gives( no pictures or further details and I cannot see how to adjust the "new style" gibs (easy to understand why they were changed) I would like to incorporate the new style during my extensive rebuild - I believe the housings for the vertical slide retainers have externally threaded bushes in them unlike mine which just has plain holes with the retaining bolts through plain holes. I cannot give any picture as what I have already said is the total amount of information that I have been able to find - a plain Allen screw through a plain hole Google is absolutely no use whatever! isimbard brunel |

Edited By MAC on 04/03/2012 10:29:07 Now that we have sunk to the level of 'ad hominem' attacks I feel that I am wasting my time here. As Ian Hewson has very sensibly said' you know best and will never listen' Thank you so much for elucidating ChrisH - such a pity you weren't quite so erudite in the first place As I have already said I feel that this has now become a total waste of my time and this will be my last post on this subject In fact it will be my last post here on ANY subject as there seem to be so many 'armchair experts' who have an opinion (right.wrong or irrelevant) on just sbout EVERY subject raised here and appear to come here for no other reason than to see their (often totally irrelevant) views published. I feel being in the workshop will be far more rewarding So carry on sharpening your slitting saws and electrocuting yourselves - Quite simply my dears - I don't give a damn |

As a guess, I'd say ChrisH's lights had been wired in series?
Two bulbs wired in series? Remove one and the other gets brighter? Now I just HAVE to see that Illustrates my point exactly! |

Firstly to Terry - I'm very sorry to hear of your devastating fire and am glad that your loss was only replaceable items. You seem to be the only person so far who has understood what I am saying. I am not going to go into further details about specific incidents as I feel they will serve absolutely no purpose and that whatever 'professionals' , qualified' people, 'experts' - call them what you like - say, you all obviously know far better. Far preferable to keep your heads stuck firmly up your own bums and carry on regardless. After all the fire brigade, ambulance service and hospitals are there for you if you are fortunate enough to survive when it all goes wrong. Sadly in my experience it is innocent third parties who suffer the most. You won't take any notice of my experience, you wont take any notice of Terry's experience as you all know FAR MORE and can quote apocryphal stories about 'quqlified' people getting things wrong that you havehad to put right! I would be absolutely FASCINATED to hear details of what was actually wrong with your installation ChrisH - you seem to be implying some sort of high impedance supply from your description but I cannot fathom out exactly what you are saying - but then i'm only a chartered electrical engineer wit almost 40 years EXPERIENCE in the industry and obviously know ABSOLUTELY NOTHING. There is none so blind as he who WILL not see. |

HMMM Just as I expected. Maybe if like me you had been involved in electrical accident investigation work then you would have different views. As a junior engineer with the local board I well remember my first 'big one'. This was a housefire caused by faulty wiringwhich had been done by 'grandad' - he knew exactky what he was doing - 'he was in REME during the war and was a TV repairman after demob' Result - house fire where his daughter and her 5 year old twin daughters DIED When you have stood in the garden of a house like that and witnessed the burned bedding and furniture, The charred teddy bears and the melted toys - the same toys that yiour OWN six year old plays with - then you might take a slightly different view Then go into the charred and blackened house and childrens bedroom and witness the smoke blackened remains of the bunk beds and see the actual CLEAN UNBLACKENED outline on the floor under the bed where the twins were 'hiding' in terror NOW TRY NOT THROWING YOUR GUTS UP The photograpf of those two little girs is still so vivid to me and often comes back to me in nightmares over 25 years later Nobody can say that these things don't happen because they do - thankfully they are rare but they happen. Maybe the worst that happens is that you get a 'jolt' - perhaps you have a pacemaker?Perhaps ypur wife has one? Or a visitor has one? Apart from killing yourselves (which is fine by me) you stand the chance of killing OTHERS and also stand the chance losing your HOME - for which you WILL NOT be insured. The fire may also spread to neigboring houses / adjoining property, vehicles, caravans, boats or whatever else might be close enough - again you will NOT be insured I can assure you that in my career that this is NOT the only incident I have investigated and am now glad to be working in another area of the electricity supply industry although I still get called upon to be a professional witness from time to time which when it is a domestic incident is always harrowing. BS7671 and part P regulations are there for a reason and no, its not some cartel / conspiracy / government plot - they are there to protect YOU and I and are here to stay like it or not NICEIC registered electricians have to have £M2 third party insurance liability - have you?

Kwil, I know what you mean but by the same token I work with women every day but I've never understood them! Bob Apparently in a recent interview Steven Hawking admitted that he didn't understand women - what hope is there for the likes of us?
But seriously as a chartered electricl engineer some of the questions and answers about electrical topics that I frequently see on this forum absolutely TERRIFY me. I for one would be far hrappier if all electrical questions in here were banned by the moderators and the very sound advice "If you are in any doubt then consult a qualified and registered electrician" was placed after every electrical question
You can't hear it, you can't see it, you can't smell it and by the time you feel it then its usually too late. |

Maybe its just me but I can't see any earth connection on this motor. If you have the slightest doubt (which apparently you do or you wouldn't be asking) then consult a registered electrician. Regulations state that any work is undertaken by a COMPETANT person - these regulations are there for a REASON. You cannot see it, you cannot smell it ,you cannot hear it and by the time you feel it it may well be too late! |

15/02/2012 20:44:40 |
I totally agree with Ian - if you have the SLIGHTEST doubt about what you are doing then consult a N.I.C.E.I.C registered electrician. I suggest you do NOT try DIY fixes suggested here - a lot of what has beeen suggested is just plain WRONG!!!
DONT RISK YOUR OWN OR YOUR FAMILY'S LIFE
And no its not costly when you think of the alternative
I have no intention of listing my qualifications here but suffice to say that I am employed in a very senior capacity by a large electricity generating company. Edited By Kinlet Hall 4936 on 15/02/2012 20:55:45 |

What is even more irritating are the replies that always start with:
I've not done this but....
or : are you sure its not?.....
as though the person asking the question is a complete buffon with absolutely NO knowledge or intellegence and then goes on at great length as to how they did something not remotely related to the original question.
There seem to be far too many people here with far too much time to waste on the internet and very little engineering/model making experience.
There are of course some exeptions. - it will indeed be VERY interesting to see who replies to this! |
Thread: Is this scrap? |
06/02/2012 12:04:49 |
No - I am not a youngster but I value my time and the older you get the more you realize how limited and valuable it is. I certainly do NOT waste it by sharpening slitting saws, hacksaw blades, centre drills, end mills (all explained in the Quorn book) or even drills under 1/8. Settig up the grinder, jig, fixture or whatever you use takes far too long - just try setting up the quorn and sharpening the ends of the teeth and the helix and see how long it takes"and unless you have an air spindle the results are suspect at best.
STOP WASTING TIME! |

Thread: Drilling brass - seizing |
29/01/2012 20:11:03 |
Maybe this is total rubbish and a "grade 1" wind-up but a very old and experienced machinist once told me to use milk as a lubricant for drilling and reaming gunmetal and PB. Something to do with emulsified fat particlesI in suspension apparently. I have never tried it but would be interested if someone has any experience of this.The chap who told me this produced some of the best work I have ever seen so I'm really not sure!

Chris,
I think you will find that genuine Calor dealers will exchange your butane bottle for a propane one at no cost apart from the refill charge for the gas. You can also swap for a larger or smaller bottle again at no cost apart from the refill charge.
This only applies to genuine Calor bottles as far as I know

Now you've got a milling machine why not make your own?
Make them 'more rectangular' so there's more metal in the bottom of the tee slot to spread the load further i.e more length running along the direction of the tee slot.

Thread: SPEEDY Lagging |
16/12/2011 20:14:43 |
As far as I am aware LBSC didnt lag his boilers. If you have already built the smokebox then you may have to cobble something up to give you a bit more room.It will obviously run without lagging but will be better if you can arrange something. |

Mesh is the same as delta.
There will be four terminals , one with 3 wires going to it and the other 3 wiuth one wire each. The one with threee wires is the 'star' point and you need to disconnect all those wires and reconnect them, one each, to the three terminals with one wire each so that you now have three terminals with 2 wires on each one - these are the 3 'delta' wiring terminals.
The plate that covers the terminals usually has the correct colours of the wires listed on it so that you dont connect the two ends of the same winding together.
While Nigel may have a point please DONT go digging into the windings at this point as these motors are usually dual voltage and are most unlikely to require such drastic surgery.
If you have any further questions then please PM me

In the reprint "Workshop Techniqes" he shows then ALL as 5/8 I have not personally built this (on the ever lengthening to do list) I have used this type of locking device many tines and never really found the distance critica - not that I would ever question a master like GHT of course.If you have (or can scrounge) a bit of 1 1/2 sq. bar then why not try a mock up - bore the main hole for the column and try each length either side of the bore.

Buy an old "Enots" oil gun. They never leak and mine cost 50p from a stall at a traction engine rally - and it still had oil in it! |
