Thread: Stuart No 10 cylinder ports |
31/10/2020 12:38:42 |
I've started to assemble the engine but have come up with a problem, the slide valve looks on the big size. as when the cam rotates no gap in the valve chest for air intake. On my drawing the slide valve is 5/8ths long is this correct for the Stuart No 10 cylinder. The valve chest on my drawing is 7/8ths so something must be wrong as that leaves 1/8 either side. Or I've done something drastically wrong. Bob.

Thread: Bending small copper tube |
29/10/2020 09:23:59 |
I have been looking for a pipe bender that will take various small size tubes, looking at the Dubro on You Tube it looks so easy to make your own but looks like a one size tube. Prices for this bender are between £16 and £44 on line, a cheaper on Toolzone at £13 are they any good ? they take various sizes and for £13 its not worth the effort to make your own. Bob |
Thread: Medical needles |
25/10/2020 02:47:22 |
Correct what Martin has said about the council collecting these needles, I have telephoned them but they didn't reply back, I suppose they are working from home. Reading these posts I would rather keep hold of them, I can inject my moving parts with oil. Bob |

Seems like they are useful, I'll think I shall hang on to them. Bob |

Thanks for the replies.At the moment I'm cleaning a pendulum clock Bob, this is the second time I've done it as it stopped after the first clean after six months. I have put the problem down to a sticky balance after I used proper clock oil, I have recleaned it all with No 1 concentrated cleaning fluid. Putting it back I will use one of these hypodermic needles with a dash of 3 in 4 oil,hopefully that will do the trick, not clock oil. Bob |

Tried all that Martin. Shame as the tiny hole in the needle looked useful , I will keep a few and smash them up. Bob |

After my operation I have 30 needles that have been used,trying to dispose them has been a problem as the chemist will not except them. Looking at them they look a good tool for a oiler on moving parts on engines and other uses. I have made a few steam lubricated and drilling a very small hole I have found that the oil soon goes as the hole is obviously to big but have drilled the recommended size. Would the needle if inserted in the lubricator be to smaller hole for the steam heated oil to pass. I shall smash them up if this will not work. Bob |
Thread: Square block with round steel balls inside |
16/10/2020 10:20:15 |
Thanks Paul, it was a long time ago so my memory got it wrong. Bob |

I am stuck indoors still recovering from a operation so I'm a bt bored at the moment so asking this question. In the early seventies my father who was on maintenance at Vauxhall motors Luton was in the apprentice school and he told me at the time that a competition with Opel Germany , how many balls in a square block can be turned. By all accounts Luton won I think six balls, if this is true is there a web site that can explain the process. Bob |

Thanks that's brilliant, Jason, John, Bob |

I'm making R R Raymans high speed marine engine from bar stock,the drawing calls for a Stuart No 10 cylinder. The drawing has no measurements for the port central distances from exhaust to the ports. Any idea please for this as knowing me I would work it out but bound to be incorrect. Thanks Bob |
Thread: Electric Smart Meters |

Very interesting link from Anthony code of practice the right to refuse 2013. Edited By BOB BLACKSHAW on 14/10/2020 11:25:22 |
Thread: Big Bang : Tallboy bomb |
14/10/2020 10:29:33 |
In the early eighties I worked in Bremen Germany, I visited the U-Boat bunker at Rekum, [ Valentin-Rekum U-Boat Bunker ]. If you can find it on Google maps its on the river Weser and the top of the bunker is full of craters, I was told that after the war it was used by these large bombs as a target but the concrete is so tough that it could not be breached. I have just googled the bunker and a web site is up and running, haven't seen it yet. Bob |
Thread: Electric Smart Meters |
14/10/2020 10:15:30 |
Very interesting replies here ,thanks. I am holding out not having the smart meter fitted but looks likely that I will be put on the higher tariff if I don't conform, in my opinion energy is good value for money so if I pay a bit more I will cut down on a over priced cup of coffee in town and that will pay for the differences. Bob I |

Thanks for the replies. I think that energy is cheap but its what goes with the meter, control over me in my house. The general public think nothing of spending £3.00 for a cup of coffee, how much energy is £3.00, it will go a long way. My father is 93 and has a smart meter, a few months ago my wife was vacuuming , the kettle was on, I was microwaving his dinner, he was watching the smart meter with concern as it is on his shelf in the living room.

Hello all, I am with British Gas for electric and gas on a contract with 8 month of the end. When signing up as with all energy companies they state that a smart meter will be installed at some time on the contract. I've had two e-mails stating that your smart meter needs to be installed, if not then I will be put on another tariff, can this be done or is this a gee up,I send my readings every month and my account is well in credit. I'm not ready for a smart meter and the problem when changing suppliers at the end of a contract.I had a chap from National Grid at my home a two years ago I had a problem with my inverter on the lathe, so the power problem was the inverter, he said at the time do not have a smart meter, he explained and in my opinion quite frightening how your power can be controlled, can't remember exactly but was worrying. So do I given in or just ignore these e-mails. Bob |

Thread: Bolts or studs |
06/10/2020 10:42:22 |
Thanks for the replies. That is a great looking traction engine you made Colin is it a working model. Bob |

I've part made A A Raymans high speed marine engine at 2/3rds from the drawing. I've noticed and on other steam engines that studs and nuts are used on the cylinder and valve chest,Is this for a authentic look or some other reason .All the engines I've made I have used bolts, as for the studs are they usually cut down from bolts or is studding for 2mm any good as I brought some a few years ago and it is rubbish, or are they generally made on the lathe. I'm sitting at home lethargic after my operation, sorry if this is a dumb question. Bob |
