Thread: Metrotropolitan Vicker Single phase motor
26/11/2021 17:58:48

A friend has a Metropolitan Vicker single phase motor electric motor with TWO (2) slip rings and carbon brushes.( Not a Repulsion type) NO connection as far as he can see to the stator. The motor name plate picture which I am unable post here, says

Cat No.6001 or could be an L. Type BAL 47 Form ABL. By the name plate the motor is very old, but might have a lot of life yet. I'm in North York's, he is in Worcester. Any ideas regarding connecting the motor directly to the mains or should it have a face plate type starter. I have never seen such a motor, three slip rings and six terminals on the stator yes, is he missing some thing ? Any relevant comment / ideas will be much appreciated John

Thread: Does charging your car battery on fast charge damage it?

Dave W should you ever get that ford POP back, I'll forward you details of how to over come those Vacuum operated wind screen wipers and to fix advance/ retard to the distributer as well. I had a 1934 Austin 7 with the same problems and with 3rd brush dynamo. I can't remember, details of the POP dynamo or charging arrangement, I should, as wife's brother had one. I remember we changed the cylinder head from another Ford engine which raised the compression ratio and it then was quite a flier. Side valve engine of course, how crude was the valve adjustment.

Simon above, make the sacrificial ANODE the POSITIVE and the object to be de rusted Negative. I use diluted washing soda in a plastic bucket and wear some disposable gloves. You will be amazed how well it cleans things the first time you do it. Lots of scum and of course if you don't clean up the object further and protect it, it soon run again. John

Bountyboy, I've an illustrated booklet relating to your MARK l l KENNEDY portable power hack-saw, and new, they were £28-0-0 carriage paid. The NON powered units were £14-0-0, again carriage paid, no doubt by British Railways with a three wheel Scammel lorry. and trailer. Does any one know what the price is of a second hand one today, I haven't seen one advertised for a long time. John

Several years ag I covered a creosote stain with several application of Aluminium metal paint, not the wood primer, still OK. John

Thread: Vintage voltage

Regarding disassembling lead acid batteries and rebuilding dud cells, when I was in the army in 1953 we had a plant in Egypt doing just that, we made distilled water and diluted Vitriol acid for the batteries, so nothing new. For ingenuity and keeping banger going, travel round the Middle East and India, where you lorry drivers with G/boxes apart on the road side, tyres with patches on the outside, remarkable people, but needs must. Forgot, straight eight engines, running on four cylinders with length of copper wire to the spark plugs. Amazing, are we about to copy them, I don't think so, we have lost that what it takes, to quick to get on the phone . John

Thread: Where to buy Colchester Bantam/Student gears

Have you had a look in HPC gears in Chesterfield or Davall in Hatfield in Hertfordshire. In the past HPC would make special for a customer, but things have really changed. John

Thread: Guillotine
10/11/2021 14:00:51

Back again folks, the guillotine is one similar to the picture John P posted, thanks for that John. I would like it to cut ex washing machine, cooker, and fridge sides which I hack out using my angle grinder, ready for making a cabinets for another WS projects. John

09/11/2021 19:14:37

I would appreciate the opinions of readers of the bench top guillotine, on the market by machine dealers advertising in MEW and ME magazines. Are they any good at all ?. I have an angle grinder and several pairs of tin shears, would i be wasting my money ?. John

Thread: compressor motor caoacitors
27/10/2021 15:40:35

The start capacitor value will be between 80/110 micro farads and the value is not critical and the run around 10 micro farads. The start capacitor, the big one is a special AC electrolytic with a short time rating, once the motor is up to about 70% of full speed, the centrifugal switch opens and disconnects the capacitor. The run capacitor should have a working voltage of 400 as its in continue use. Both caps in parallel when the motor is stationary and one (10) when running. Most multi meter with a capacitance range, have working voltage of 9 volts and motor capacitor really need to be tested at full working voltage, 339.4, hence 400. John.

Thread: Microwave Oven
25/10/2021 16:19:09

Regarding Micro wave cookers, once discharged the capacitor, the high voltage diode are useful and the wire from the transformer for recycling. Some PC boards have useful components which can easily removed with a hot soldering iron. And, as some one already said the cabinet, if you can make a new door and chassis the cabinet are very useful, for a power supply etc. I might add some gas cooker, gas boilers and washing machine are a good source of sheet steel.

Ignatz, please tell me where you got the oil gun tip from as the club needs one, and yes, PTFE tape will easy cork it oil tight John

Thread: Vfd and motor efficiency
13/10/2021 09:38:53

Martin, a couple of years or so ago some on this site posted a series of picture of how he located the Star point on his motor and then reconnected it in Delta worth locating. Not a difficult thing to do, but a rewinder will be able to help out for a fee, think £50 plus an hour. John

Thread: Workshop lighting / energy costs

Many thanks Anthony worth knowing, I'll be getting to work with my Dremel as we have a couple of dud ones. John

07/10/2021 12:22:19

Hello Anthony, OK about the repair once you have the board out, but tell us how you gained access to the board. I thought the envelope was glass as before, is it now clear plastic ? I bought three lengths of LED with self adhesive backing, I attached it to some 25mm plastic angle and secured them to the roof of my workshop, all driven via an old computer PSU Easy to carry out, no main wiring involved, other than to PSU and what a transformation, lighting wise. Using LED strips you can cut them to length, as they are diodes in parallel and with careful use of the soldering iron join odd bits up to size. John

I've been using pallet wood to make hedgehog houses, made 20 and given them away on Freegle. One pallet had really hard wood runners (thick bits), I offered them to the wood burning neighbours, but no takers. Most folks don't have wood saws any more, just get the man in.

Thread: Myford clutch design - ME 4322
28/09/2021 17:49:19

I, and a couple of friend successfully made clutches for our super 7 following an article in MEW and which are still working OK today. I think it would also fit the ML7 just as well. perhaps a reader one might know which issue it was. John

Thread: Multimeter recommendations

RS safe blocks, very useful when carrying out repairs, but H&S thought they could be possibly dangerous so out they went in Colleges and Schools. I got mine at a Mobile Rally several years ago. Another useful bit of repair kit is a 13 amp socket outlet box with a length of flex and a 13 amp plug attached. ( A modified very short extension lead in effect) The socket outlet NEUTRAL is brought out externally, via very well insulated loop so that you can place a clamp type meter around the neutral, and measure the current without any disconnecting. (I have a UNI - T UT 210E , these clamp on type will also measure DC loads) The load is via 13 amp plug as normal, which is inserted into the adapted box. John.

Ah, but you don't get an Earth terminal on the Aldi meter. Some thing very special about an Avo, that special smell when you open the box and then see the quality workman ship or should I say Ladies work. Should any one be really interested in AVOs and all the they made and their repairs. I suggest you go to "Vintage Radio" where there are some experts and collectors. Not me i have only got eight. John
