Thread: 3D Printer On sale in Currys for under £1,200 |

Accepting the limitations on resolution/surface finish, some of the ideas I have had include:
Not an earth-shattering list, by any standards. Neil Surely for sandcasting moulds, you could use hollow patterns? |

Hi Martin, for some reason I don't see one side of each spoke Thanks Neil |
Thread: Calculating volume in metric |
02/01/2014 19:02:45 |
It cheers my Imperial sensitivities to see so many 'up to date' metric head advocating the long-deprecated cubic centimetre! Neil |

Google's Picassa will rotate videos for viewing but not save them in the new format. I think the (excellent but tricky to get the best out of) Pazera free video converter will allow you to rotate videos.b It also converts GP3 phone videos and quicktime ones to a windows friendly format. Neil |
Thread: Slitting saw advice |
01/01/2014 20:19:54 |
I vaguely recall only slitting one side of the eccentric, so it could be tightened up to compensate for wear (as if it will ever be run for THAT long!) I'll go and check... ...indeed that IS what I did. The cut is dead square and very neat - I am totally bewildered how I could have made such a good job of it without a very thin slitting saw. I can only think I used a razor saw and ran it along the top of the vice? If only the rest of the thing was as well made - it was my first 'proper' attempt at model engineering! Neil |
Thread: Celebration!!!!!!!!!! |

Thanks John, After this DIY all gets done I plan to get back in the workshop and make a smaller drive gear and go back and conquer the1 in 10 track at Derby If anyone would like a look at the plans as they are now (comments welcome) just send me a PM Neil |
Thread: supercharged V12 2 stroke |

I hate it when people's jigs and fixtures look better than my finished work... Neil |
Thread: Surface finish |
01/01/2014 19:22:28 |
Hello Gordon, Looking at your second picture, there's quite a large 'step' at the top of the test piece which suggests to me that you are taking quite a hefty cut. Is it possible you are driving the shaper a bit too hard? Neil |

I hate Dalo poens ... but what did I do today? > kitchen table Well if that is eligible can I mention that I tiled the kitchen? At least the 18" above the worktops, with the exception of finishing round the plug sockets. £4.20 for 8 50mm socket-fixing screws - I should have made my owm actually i [probably will need to make 2 as one socket is now 3/4" further out from the wall - whoever built our kitchen extension did not work to ME standards of squareness and accuracy! Happy New Year to all! Neil

I learnt not to guide drywall screws into plasterboard with my fingers. The darn Wickes screws left well over a dozen little steel splinters in my left index finger and thumb Neil |

Very neat. Makes the rough-hewn sled my Suffolk is on look a bit sickly... Neil |

Hello H, I have nearly finished drawn up plans. I'm hoping to write it up for ME in the New Year. Neil |
Thread: newby needs help with lathe |
30/12/2013 12:07:02 |
Hi Simon, Others may disagree, but as this is a fairly modest sized lathe witha relatively light spindle, you could consider getting a backplate made that has the mounting holes and register for fitting mini-lathe sized chucks. This would keep the costs down and you would only need one backplate for 3 & 4 jaw chucks and a ER collet chuck (if you ever want one) Neil

FWIW I cut the eccentric strap for my 10V with a junior hacksaw as the only slitting saw I had at the time was 1/16" thick. There is plenty of metal for cleaning up the cut surfaces, even if a thin slitting saw wanders a bit. Neil |
Thread: Shaper cutting tools |
29/12/2013 17:50:19 |
Hi Mike, I went self employed... but most of the time its been DIY keeping me out of the workshop and off the computer! Neil |

Thanks Martin, It imports, but I'm not sure if what I get is what you intend! Neil |
Thread: Adept No.2 Shaper |
29/12/2013 17:42:27 |
Hi Paul, Back in the day Hoover made some very lovely motors for machine tools, so it [probably isn't from a washing machine if it looks like the one below. If it has oil cups at each end pop a drop or two of oil in every day you use it. Neil |

Can anyone give me a link to a 'test' DXF file to test the import on this programme? > they have a tooth difference of 5 teeth. Sounds like my Dad's mouth... before he got his false teeth. Neil Edited By Stub Mandrel on 29/12/2013 11:34:23 |
Thread: Shaper cutting tools |
29/12/2013 11:28:25 |
Someone recently pointed out that much carbide tooling needs to be worked fast so that the heat generated softens the cut, but the reciprocating action of a shaper limits the speed that can be achieved. That said I know some tipped tooling is meant for finer cuts and slower speeds, but this is the area where the superiority of tipped tools over HSS becomes a moot point. Neil |

Hi Graham, Your main problems (aside from and excess of rigidity at the expense of flexibility) could be:
That said you could address any or all of these with ingenuity. Neil |
