Thread: Single phase motor woes |

Thanks Joe, good advice |

Looking for some advice on a motor/pump issue. We have a hot tub,The main pump is driven by a single phase two speed motor. The symptoms are that the motor intermittently stalls in low speed. Sometimes it will run for hours and sometimes just for a few minutes before stalling. The pump seems free to turn by hand and it will always restart OK in either low or high speed mode. So I am suspecting something resulting in lower torque on the motor side, although I am not ruling out a worn-out pump. The motor wiring plate is marked 4P for low speed and 2P for high speed. It is a dual capacitor unit. The caps look in good condition with no signs of bulging. The motor doesn't seem to be hot. Would an intermittent run cap cause reduced torque resulting in a stall? Any advice from the motor experts on here would be appreciated. |
Thread: Dividing Plates |
26/11/2017 19:42:00 |
As an apprentice piece we had an exercise called a polygonal pyramid to get us used to working with a dividing head. A 3 inch turned blank of aluminium with steps of decreasing diameters. Onto this we had to mill polygons from 3 to about 10 sides. Mine went well apart from one was a few degrees out from backlash. That was over 35 years ago and I haven't used a dividing plate since... I would recommend this sort of exercise to practice before cutting anything important. |

If you Google "dividing head manual" and find the Grizzly manual. That has a good worked example. |
Thread: Not an industrial injury, but... |

We are drifting way off the original topic here (sorry) , but here is before and after from Saturday. Not a competition winner, but gives a good idea of what it is all about. I ran out of time to finish it tidily. The idea is to make the hedge stock proof by cutting the stems (pleaching) and laying down to fill the bottom of the hedge. Stakes and binders are put in to stabilise the hedge until it grows back up from the bottom, which it does surprisingly quickly. The idea of pleaching is to cut the stem almost through enough so that it can be bent over but allowing enough cambium to keep it alive. It takes skill to be able to do that quickly without going all the way through... There are many different regional styles, this is Midland. The competition was held on the main road between Burford and Stow on the Wold, just past The Merrymouth Inn if anyone wants to take a look. It is a great rural skill to learn and keep alive. Given the heavy rain on Saturday, I would have rather have been in the workshop though! |

A chap has just laid a hedge near me, it looks so much nicer than a hedge that has just been flailed into shape. It took a few days to do what a flail would do in a few minutes though. Mike The competition I entered, novices had to do 8 yards in 5 hours. Intermediate and open was 10 yards in the same time. As a novice who hasn't had that much experience, the time was very tight. Mind you I was the only competitor not using a chainsaw. |

Ditto with office hands. Did a a hedgelaying competition on Saturday for the first time. |

All the apprentice pieces I made, many useful tools, are stamped with my 4 digit BAe "Clock Number" I wonder what people will make of that in the future. |

Very sad news, my thoughts go out to his family and friends. He was a huge inspiration to many in this community. His "old school" triumph of experience and practice over theory brought him huge respect. This combined with a vicious British sense of humour means that he will be greatly missed on our online community. RIP Sir John, may you keep cursing Bridgeports and fixing what's broken where every you are. |
Thread: Faceplate or Independent Chuck? |
22/10/2017 14:10:55 |
Both have their uses, but a.4 jaw independent will get far more use than a faceplate. It depends what your are machining though. For example a faceplate is no good for machining a slide valve eccentric. There is no way you can hold it on a faceplate. The 4 jaw is invaluable for precision work, where you need better alignment that you can get from a 3 jaw. Also setting up work on a faceplate takes a lot more effort than a 4 jaw. If budget is tight buy the 4 jaw and invest in a faceplate later when you a get a job that needs it.

RS Components rswww.com do a range of slip and India stones from Norton. I have 211-9522 which is a good shape for finishing or touching up lathe tools. |
Thread: Can titanium be soldered to brass? |
28/09/2017 20:18:55 |
Another blast from the past. It seems that most of my posts here are reminiscing about my apprenticeship. I did a 3 months stint in the aircraft laboratories at Brooklands. I was helping out on a research project that was investigating a new surface treatment for preparation before bonding titanium. Mostly I was doing the grunt work of filing the edges of two test pieces that had been bonded. The objective being to have a clean surface so that you could see the progression of disbonding when a wedge was driven between the two and the sample subjected to a steam cabinet. We went through files in very quick order. I would think a epoxy glue should do the job after making sure the join is thoroughly clean and degreased. |
Thread: Colchester student lathe |

Slightly different scenario, when I first got my Chipmaster, which is VFD powered with the original variator and motor. It wouldn't run at full 3,000 RPM. It was drawing too much current. Following an oil change and a gentle run in with gradually increasing the speed. It will now run at top whack, provided it is warmed up first. Not that I really need 3000 RPM! |

Thread: Offshore wind now cheaper than Nucular |
11/09/2017 13:27:54 |
Last year wind was only generating for 36% of the time (according to the BBC news article). So something has to fill the gap. We don't have the ability to store renewable energy at any scale yet either. There is also going to a a significant change in electricity usage given the targetted move away from IC transport. All these electric cars will need charging. Nuclear has served this country well over the last 50 years or so, but alas we have lost all the knowledge and skills in our own industry where we were once world leaders. The legacy of Nuclear is very expensive, but it is a reliable source . There are no easy answers here. |
Thread: Raw black rubber |
30/08/2017 19:54:29 |
No idea on a source, but I spent a couple of weeks in the rubber moulding department at BAe Brooklands during my apprenticeship. They manufactured non standard seals and mouldings for both prototype and production use. There was a great variety of raw ingredients, which were mixed up and milled before moulding and curing. It really was like cooking, the recipe had to be followed exactly or the result was a disaster. Looking back on it now there was so much I picked up in those days, it just needs posts like these to jog my memory. |

In the aircraft industry (at least in the UK) fasteners with Unified threads were specially marked to prevent safety issues with mixing different thread types such as the OP suggested. This was three touching circles . Example about half way down the page **LINK** |
