    Single phase induction motor start up problem

    Many thanks for that, Bob, but please do not do anything that takes up your time as Mr Sod and his associated Law have just paid me a visit. My bench testing cannot reproduce the fault - at least 50 starts on a B16 breaker and not one failure (wonder why I put a 16A breaker on my workshop ring...

    Single phase induction motor start up problem

    Interesting thought but somehow seems a bit of overkill for something with a 650W motor and driving a load with very little inertia. Bob - any thoughts on the idea of odd voltages occurring ? Rob

    My precioussssss........

    John - has the year really passed since you last 'suffered' this experience ? I do seem to remember a story of a rather magnificent hangover ? (hammer) (hammer) (hammer) Rob

    Single phase induction motor start up problem

    Hi Eric You'll see 9Fingers Bob's explanation of the starting arrangement of this motor near the beginning of the thread. I've had a suggestion of dust on the centrifugal switch contacts, but having suffered that for many years on another motor I doubt it is that unless this motor has...

    Please send me some boring wood!

    Is that 'Nope - I don't have all my fingers still' :lol: ... or 'Nope - I haven't looked!' Rob

    Single phase induction motor start up problem

    Thanks Eric - that's actually quite useful information. I hadn't thought of capacitors in series (equivalent to resistors in parallel). I'll need to see if I can find a suitably large value one to make it work - will dig into the electronic components junk box, but may need to 'charge' up any...

    Sawing a log guidance please

    I collect odd bits of wood and have two at the moment that I'm not sure how to process for the best. The type of wood isn't important as any answer will apply to all woods, but one is maple and the other almond. The almond is a crotch - how do I cut that to get the best out of it? The...

    Please send me some boring wood!

    Gus - Have you been following the thread in the General Woodworking forum on Yew ? Somewhat appropriate seeing you're in France - do you have all your fingers still? Rob

    My precioussssss........

    There is a solution to this problem - you make one for yourself and then copy it, having found how to make it, for selling. I have several bits like that - and it does help to pay for all those toys that you simply MUST have as a turner! And then I do a production run of rattles - it really...

    Single phase induction motor start up problem

    Thanks Paul - warning is fully appreciated. I've brought the motor home so that I can do some measurements on it. I did have an alarming phone discussion with Axminster's technical department this morning. The guy took the details, said he didn't know anything about this and put me on hold...

    Single phase induction motor start up problem

    Thanks for keeping going on this Bob - I tried measuring the capacitance with my 3 1/2 digit DVM, but it ran over scale. Its maximum is 200uF - I suppose that does indicate there is capacitance there at low power. Doing current measurements, etc will require a 'bring home to the laboratory' so...

    Single phase induction motor start up problem

    Any suggestions as to why after 3 years this is occurring ? The only possibilities that exist then is failing windings or mechanical overload, and I'm comfortable that it isn't the latter, though I could go the extra mile and disconnect all the oscillating gearbox from the motor shaft. The...

    Single phase induction motor start up problem

    Thanks again for your help, Bob - that explains the voltage rating, and agrees with Ebay in that there is a 2:1 price difference. Having said, if I can get the higher voltage one fitted I think I will go with that - I could use the excuse that it isn't my money but for all the effort of...

    Single phase induction motor start up problem

    Hi Bob - I was hoping you would be around somewhere ! I was thinking of PM'ing you but experiences of this type are well worth sharing. Many thanks for the final comment !! "Electrical understanding", as all of us who have *some*, can get you into trouble on occasions. :shock: (title of this...

    Thickness ant type of wood shelving for storage area

    The Sagulator is based on sound formulae for beam design. I cross checked a beam design I had done and got near enough identical answers. Rob

    Oi! Yew! Before I kill myself.....

    Not heard the term 'pineappled' before - I hope what Mr Google suggests this urban word means isn't quite what Pvt_Ryan meant ! :D :D Rob

    Single phase induction motor start up problem

    The wood working club has a bobbin sander made by Jet and bought from Axminster some 3 years ago. Recently it has been tripping the C32 RCBO on the ring it is on as it starts up. This is random. Many times it will work OK, but on the umpteenth time there's an initial spin of the motor and...

    Oi! Yew! Before I kill myself.....

    Just to offer some additional reassurance, I worked for a period with my cabinet maker brother, and made myself a desk of yew (now supports this keyboard and monitor) over 20 years ago at his premises. I never thought about any hazards, so it was machine cut, machine planed, hand planed and...

    OIling a wood carving

    We bought an 18" long sleeping wooden duck last summer. Makes a nice decoration by the pond. It's carved in a burr which at a guess, because the wood is definitely yellowish, is chestnut, and like all burrs is what might be described as characterful - ie has holes in it ! The seller told us...
