David, I think you will find 19mm bearings cheaper than 3/4". I find imperial size stuff is getting pricey now it is not used often. |

As above, skim in the lathe including the main roller if required. A job like this is not size critical. Make bronze bushes to suit the new spindle size or sleeve the spindle to suit roller bearings if that was your plan. I would not make it again. |

A cheap and easy option is a fan. I tried a dehumidifier and was emptying 2 or 3 litres a day, it was then I gave up and find that a fan running is all that is needed to move the air around. |

Well I had a very prompt quote for an A4 size piece of 6mm felt. £15 I can live with that, but £13.84 postage; no thanks. |

Philip, you where a long way from me in Brum. Happy days and a very good training at the GEC. I did six years as an apprentice toolmaker and still can't see how modern apprenticeships can be done in three years. |

Thanks for the link Grizzly, I have sent an enquiry. I never found them when I searched before. |

"Just use a magnet it's less messy" but not for the 400 series stainless which is magnetic. |

I do not wish to hi jack the thread but; has anyone got a supplier for felt to make oil/bearing seals. I have tried chiropody felt but it is to soft. I need a sheet about 1/4" thick for seals on an old motorcycle. Chris. |

Phillip, I can not answer your question but I also served my time at the GEC. Moulded Plastics Division toolroom from 1963 until 1970. Where where you ? I know they had sites all over the country. |

It is pre war Brit stuff for me and a Yamaha Diversion owned for 20 years. I also make/modify/repair lots of stuff for other peoples bikes. A very enjoyable way to spend my twilight years, |
Thread: Valuation of Boxford model A lathe and EMCO FB2 vertical milling machine |
02/12/2015 15:59:46 |
Nice lathe a copy of the South Bend I had for 45 years. As for value a local dealer has had one in his showroom for a year or two with a £1100 price tag. I sold my well worn South Bend for £200 a few years ago. The Boxford will be snapped up soon due to its size to fit in a home workshop, any tooling with it ? No idea on the mill, Iv'e never seen one. |
Thread: metric 123 blocks?? |

I would just use the Imperial ones you have and a calculator. Job done for no cost. |
Thread: Preventing scaling |

It is a shame you do not have any local engineering or toolmaking companies to put these kind of jobs in with their batch. When I ran a mould making tool room we specified "Vacuum Hardening" for parts we wanted to come out clean. I was always willing to put odd bits in with our work as most times we where no where near the minimum order value. |
Thread: Modifying a hardened Machine Vice |
01/12/2015 13:29:25 |
Working all my life as an Injection mould toolmaker I have cut plenty of hardened steel. We got to the stage where we would rough out to around 2mm per face then harden to 52/54 HRC and finish after to eliminate distortion from hardening. Modern coated carbide cutters work well, keep as ridgid as possible don't be tempted to use big cutters 6/8mm for what you intend to do is fine. Keep the speed up and light pecks of around 0.010"/0.020" a fairly rapid feed rate so the carbide does not dwell and rub. Good eye protection is a must and may be gloves, the chips come off fast and hot. |
Thread: HI, I'm Iain |

Welcome Iain, from another newby. My machinery is a bit bigger to cope with motorcycle parts and not models. Enjoy the forum and the hobby, when you get in the workshop time evaporates ! Chris. |

For BSA unit singles Rupert Ratio's books are highly recommended. They give what it should/should not have and all the fixes to make them reliable. |
Thread: Chipmaster power issues |

I have not seen the Clark converter but do have two differing ways of running my machinery. The lathe has a three HP motor that is not dual wired to run 240v or 440v so that runs off a Transwave static converter of around 4.5HP capacity at the 400 volts. My Bridgeport mill was originally wired to run off the same Transwave kit but was never happy and would stop after a short run time. This was changed to a digital inverter drive (a cheap Chinese one for around £90) the motor was changed delta to star or the other way around and runs perfectly. I did not do the wiring, that was done by a friend who knows what he is doing. What I am saying is these things are not a plug and play, most ordinary household electricians have no idea on the three phase wiring . |
Thread: Internal Combustion Engine Supercharger |

Having a life long desire to compete in various forms of motorsport I have "Blown" a few of my cars. Always by buying the blower and making up the bits to fit and get it to work. Is your wallet big enough for a steel crank? I would be reluctant to add a blower to an original Seven. Maybe get hold of a reliant engine to play around with. If you do go ahead I suggest casting the main casing. A good aluminium foundry local to me (20 miles) here in the Midlands if you require castings. Chris. |
Thread: Finding the centre of a hole |
29/11/2015 16:40:28 |
In my 50 years of toolmaking nothing beat the piece of bent 1/4" round bar to hold the DTI. Simple and effective and used in a drill chuck or collet. I have several sizes made up to centre work pieces round square of rectangular all use the same bars. So bend a piece of bar to suit the diameter of your attachment for holding the DTI. For most work bend at 90 degrees with say 2" x 3" and job done. |
Thread: Turning 304 stainless |
28/11/2015 22:23:18 |
I take it that it is a motorcycle wheel spindle. I am not a lover of stainless for this type of application but have made a few. (I would use EN16T). To get reasonable results try turning at around 500/650 RPM and apply a little cutting compound to the work piece. This should stop it knocking the tool about, if no better go a little slower. Screw cut to within 5 or 10 thou and run a die down with plenty of compound to ease the cutting.Lubricate the threads when fitting the nuts to prevent galling. Chris. |
