Thread: machining ''Peek'' ...and ''Carbon fibre'' |
14/10/2013 22:05:31 |
Carbon only splinters with incorrect tools 118 degree point derills splinter 90 degree points do not for bigger holes orbital drilling is used ,think of it like a circular pocket cycle on a cnc ising a flat bottom boring bit Are you trying to profile mill drill or pocket the carbon the only cutter which looks familiar in proffesional composites machining is the humble ball mill and then we use CVD or PCD to make those last the rest look more like Burrs All will have a different cutter geometry than a trditional carbide mill bit as the top and bottom face of the sheet will want to delaminate these are called (google) compression geometry milling tools 15 and 25 degree helix are normal here if your machining a few bits and bobs you will get by with DLC coated carbide, this is not for production use though they wont last
Easiest way to cut carbon sheet is high pressure water ,we use a 5 axis water jet in aerospace for this |
Thread: Why is this site so negative ? |

John is that a complaint abot complaining? The silver cross pram is still pressed in the UK down brighouse in yorkshire, i visited a company recently who had a workshop full of large old presses, you know the ones you used to find in industry which are 3 floors high every component is pressed there and they are still made in the UK It seems complaining is the order of the week a chap i follow pointed out some more negativity on twitter last night he runs a company called the Bicycle Academy basically teaching people to build bicycles, again and teaching them the right skills and the right way of doing things. Again a very nice gentleman organizes a show for handbuilt bicycles and is getting flak for moving the venue , I don't think a lot of people realize it takes a lot of work for any outlet and people give up precious time to do this paid or otherwise Its all to easy to complain |

Rowland Interesting I actually made the first ever europa whan it was known as aviation composites ,this was back in te days when Ivan ran it A slightly more costly example is to use the company watsons anodizing in barnsley ,thats where a lot of stuff was done in the early days of 001 in fact they will provide you with a finished panel Edited By mike mcdermid on 29/09/2013 12:20:55 |

I like John ponder what is next ,Progress means your generation and mine will be a curious antiquity Model engineering at the moment will move into the realms CNC as industry starts to move away and use more modern technology Machining lumps of metal is wasteful and needs skills there is already a massive massive discrepency as those skills dissapear (i work in one of europes most advanced manufacturing centres for this stuff and if some had their way composites and plastics are far better choices) they need to be taught ,only recently have University training colleges been set up here ,but its a bit late as over the last 20 years there have been no apprenticeships ,well in the sense of time served and such The next generation will not learn engineering as we define it They wont even have a use for CNC companies will buy a design from company A pay for it and print it either themselves or via company B , I dare say model engineers or those hobbiests of a mechanical ilk will buy the design and print it from an itunes like app store or you will become a designer for others to print your wor Its much the same as it is now when a drawing gets printed in MEW issue ??? but we wont be reading a drawing and machining it I agree with harold to some degree but not in others i have a Hurco VMC here in the shop and for some things it takes no longer to do the cam set up on the computer program and run the Job even for very simple things , however there are some things it is just easier to do manually Its certainly no slower to , people wonder why there are old manual machines in my shop ,there seems to be this middle ground of hobby CNCs which in all honesty I frown upon as toys, sure they are computer controlled and they cut metal but thats where the similarity stops, We are not there yet printed parts are still very poor at holding tolerance but it is coming, I dare say the generation after that will probably not 3d print an object ,a machine that arranges atoms will just materialize the product from a pallette of chemical elements, that last sentence isn't a technology my imagination just came up with, now imagine how tight a tolerance you can get with atoms MOST importantly however ,sometimes its just nice to make things by hand the old way?,if history serves even archeologists dig up things from 100s of years ago,that people have made by with their hands, i hope its just human nature |

Edited By blowlamp on 08/09/2013 20:17:51 Unfortunately this is not the case a very valid assumption is that there will be someone to take your or my place shortly , On the other hand i have also seen disgruntled members start their own succesful web endevours only to find that when they are in the hotseat it becomes apparent the moderation they once suffered (if that is the correct term) they now have to enforce Edited By mike mcdermid on 09/09/2013 20:24:37 |

The body of the linked-to eBay ad in the OP does say it is "suitable for Myford and other lathes" so I don't think they are trying to pass it off as genuine Nottingham product. It is perfectly legal to use the brand name to describe parts, new and used, in that manner ie, fits brand x, suitable for brand x etc. Happens all the time with car and motorcycle aftermarket parts. But yes the ad's headline "Cabinet, Myford lathe" is a little close to the wind. But basically can be read as "Cabinet for Myford lathe", which would be perfectly legal. But legal is one thing and companies threatening to pull much needed advertising revenue is another, especially in struggling small specialist publications with a competitor or two only too happy to take the business. RDG would have paid a lot for the Myford name so one can't blame them for doing what they can to protect it. And as far as freedom of speech in forums goes, it's like going to someone's house: You are free to say whatever you want. They are free to kick you out if they don't like your presence or what you say. Freedom of speech never has been formally enshrined in British law. And its defamation laws are the most draconian in the world outside Russia, China, North Korea etc. So don't feel singled out. It was the made using original patterns that got my attention, i first thought these guys must have made these for the original Beeston Myford, then it dawned the original paterns belong to RDG now To be honest its getting to be like America a patent or trademark weather its morally right or wrong or which side of the trademark /patent your on ,it means nothing unless your the guy with the biggest lawyer ,think its called legal engineering , Edited By mike mcdermid on 08/09/2013 13:20:25 |
Thread: ME/MEW Articles? |
08/09/2013 12:20:34 |
I think refurbishment, modifications to machines you have could make, forums are full of people asking these questions those old tips workshop tips that are becoming forgotten , history of tools/manufacturers things like custom tools .plans drawings ,was reading Geo H thomas book the other day , boring bars homemade? might make good articles / might not |
Thread: Stepperhead feedback |
08/09/2013 12:14:31 |
This is going to sound very harsh and this isn't a reflection of the lathe whatsoever as it was simply superb in terms of engineering and excecution When every issue of MEW fearured some aspect of its construction however i really did lose interest in the magazine as a whole, there seemed to be little in it other than ads and how to build a lathe which was for the most part something too big/complex a project certainly for me to be interested in and maybe a lot of others. If it had been a supplement sure i would have probably kept them for reading aside or if there was a website dedicated also as i could browse at my leasure

Mike, In the case of the link above RDG/Myford would be in their rights to have it removed as it is not described correctly. The company has use the Myford name directly when they have no right to do so and it is not a genine Myford item.
Now if they were to describe it as "Lathe Cabinet SUITABLE for Myford" then there is nothing in UK law that RDG/Myford or Ebay can do anything about it.
This has been the crux of the whole episode going back nearly 2 years. RDG/Myford have been removing items off Ebay that have been correctly described as either suitable for or genuine items from the Nottingham factory, pre the sale to RDG be they new or used.
Which reminds me I have to get some photos of a set of brand new GENUINE Myford VM-B lead screws and nuts sorted to go on Ebay, Probably the last new set in the world.

I agree i think they are pushing the boat a little far with their ad

I noticed it last nigth when i found this on ebay and was wondering if RDG/Myford would be throwing their toys out the pram Myford advertise on this site so i suppose being as they spend more money on ME than you do it makes sense (awaits denial of moderators) to keep them sweet, This happened a lot with motorcycle publications where a bad review meant spitting the dummy out with the publisher TBH Anna there are plenty of other lathe manufacturers out there who ake products cheaper and as noted by the users on here who like their cheaper machines ,folks will vote with their pounds and pence not what gets deleted at the request of a company who are using the edinburgh defence or backpedal when they get a bit of backlash regards their actions. Its the internet, sadly this is what happens and moderators of websites can come under fire from companies who would like to threaten action, because of opinions voiced by others on their site, its a rock and a hard place for them, its not just this website tthis kind of thing happens on ,a lot of others are far worse

Actually reading the Myford lathes user group quite taken aback by the fact myford want 8K for a new or remanufactured Super 7 As im selling on my V10p and just having witnessed a Boxford 330 go for 900 quid on ebay (gutted to say the least) It piqued my interest to phone boxford in Halifax and enquire as to just how much a new 280 would cost 8600 QUID for a new UK manufactured lathe and their order books are full im told by orders from the NEW University training colleges This is good news in my book as it seems there is investment going on in engineering and you can buy a damn fine machine for your money Im wondering which company i would spend that kind of money with |

Thread: threading metric on an imperial lathe |
01/08/2013 22:34:49 |
Good evening all. John The threads are indeed just for fasteners and the like ,Say for example a long shaft with 10-15mm of thread on the end Graham it is an Emco V10 i have read the user manual and it mentions either metric or imperial gearboxes Harold Unfortunately I do not have any change gears other than those that came with the machine,there is very little wear in the machine however, so i would say the leadscrew is pretty accurate? Many thanks for the replies, Where would i get metric change gears? Mike
