|Thread: Garador door closer|
That capacitor shouldn't be even warm, electrolytic capacitors age and dry out and then become in effect a series resistor, hence the heat. Have a look on RS, Farnell, Rapid, ESR for a replacement and look out for the continue band along its length that is the negative, got to get it soldered in right first time. I have some where a complete door system, motor, arms and I think two hand sets etc, was all working when my friend moved to a double garage bungalow.? Might you be interested ? John
|Thread: What Did You Do Today 2021|
Nigel regarding early Myford gear box, I had one and fitted it to a lathe about 20 years ago. I think I had to shim the G/box mounting away from the bed to get correct alignment of the lead screw. Also I found much to my dismay several gears with teeth missing, I bough gears from HPC at Chesterfield which I had to sleeve. Took some time, but work out OK in the end. John
|Thread: Myford ML7 service in Devon|
I suggest you have a look on Ebay as a guide to the lathe is worth, and as others have said try and locate any attachments for the lathe. Also if there is a Model Engineer/ railway club in the area, contact the secretary as the members might offer help with identification of any accessories for the lathe. John
|Thread: RAF to give up flying planes.|
Don't know about Spitfires, but some where in WWII there was "LINK TRAINERS" and if you live near a training air field you would be please.
|Thread: Lathe Move|
If its on a pallet, then Pallet Ways is who you are looking for. An old friend of mine has had lots of machines moved by by them. For us, its some where on Teeside, maybe nation wide. John.
|Thread: Multimeter recommendations|
Fluke for me. Anchor Trading at Notts used to sell ex army ones, but Anchor had a big fire a few years ago. Aldi and Lidl will do for most things. Forget the capacitance rang for motor Caps, as those caps should be tested at main work full voltage not 9 volts, and how often do those cap fail anyway. An Avo or similar is the best for testing the likes of diodes and transistor out of circuit testing. John
|Thread: MIG gas/gasless welders - recommendations?|
I agree with Dave above re the welding forum, also a good book " Farm welding" lot of good pictures. No signs of the farmers friend, bale twine at all. John
|Thread: Pinnacle PDM-20|
Scarborough mens (Mates) have been given a Pinnacle PDM - 20 mill/drill. Has any one got the same mill which was made in Taiwan but badge under a different name. Apparently several dealer sold similar if not the same machine in the 1970/80.We would like a handbook or a copy. An advert for a Pinnacle drilling machine is entirely different machine. Thanks to the three respondents, but no help. John
|Thread: Machine Lamp Recommendation?|
I have two 30 LED "sewing machine lights" on my super 7 which work from the mains. They come with a two pin plug, which I removed and fitted a 13 amp ones. The lights have a small circular magnet at the end of flexible piece around 10" long, got them via ebay and they are listed as "sewing machine lights". Wife has one on the sewing machine and I've one for soldering. John
|Thread: Myford super 7 lead screw|
A friend who is miles apart from me, has dismantle his Myford super 7 lathe to give it a once in a life time clean, now he cannot get the lead screw back in position, passed the apron. Can any one who dismantle a Myford offer any explanation of what he should be doing. I have looked in my handbook where there is good exploded diagram, but no text. If a reader can help, please PM me with a phone number which I will pass on to George and he will call back.. John
|Thread: Newman Motor Star To Delta?|
A couple of years or so ago some on here posted a series of picture on how he did the conversion and it explained in detail of he did, very informative. I've done a few for friends and have 500 volt DC insulation tester (Megger) to test the final result. You need to take the motor completely apart to locate a LUMP in the windings, mark each end the the motor and take a lot of picture as you go, to enable you to reassemble the motor on completion. Have you look on Youtube some must have done the conversion on there. John
|Thread: Coolant pump - how to slow flow rate?|
I have several short pieces of BLUE hose as shown in Paul Lousick comments above. Can any one tell me how to join them up, I have tried hot water and hot air gun. Not there yet but keep on trying. John
As DC 31k says, you wont be harming the pump restricting the output, but do ensure all connections are sound. Your heating system pump/circulator works just the same. Can you fix a bi-pass arrangement which puts less pressure on your connections. John
|Thread: Manual/ book|
My local "Mens Shed" have been given a Pinnacle PCD 30 bench top mill / drill, has any one got a parts instruction manual available for this machine. A copy will be OK. Thanks in anticipation. John
|Thread: Chipmaster motor wiring|
To John Haine, A friend of mine altered his motor prior to wiring in an invert and he had a "backward" connected winding. I sorted the problem by reconnecting each, one at a time, can be tricky never the less. When one end is incorrectly connected you are not forming a triangle, not sure of the title of the new shape. . As always there is a way out. You will ned an analogue multi meter or a low voltage DC volt meter ( 15 or less) will be OK. The reason for the Analogue type is because you will be looking for a quick flick or deflection of the needle + or - and most digital don't show that easily. In the past I've used an AVO set on 10 volts DC, start high and work down to the 3 volt range rather than damage a meter. Using a crocodile clips connected to the meter to leads, to say V1 and V2, doesn't matter which of the three pair you start testing. Using a 12 volt car battery or any 12 volt DC supply connect the Negative lead of the battery to W1 motor lead, and then very quickly dab Positive lead to W2 us should get a small kick / deflection on the meter. If the needle is attempting to go in the Negative direction exchange the labelling on W1 and W2. Conversely if the meter reading is in the + direction you got it right first time. Now go to the other two windings and do the same to them. I think I've got it all correct. John
|Thread: Myford super 7 with gearbox - leadscrew stopped turning|
Have you broken stripped a tooth or two on the two fibre gears by the tumbler reverse. ? I hope not.. John
|Thread: The "Lost art of hardening copper"|
Avometers 7 & 8 and most other analogue multimeters had copper oxide rectifiers, which looked like 4 little copper spring in a plastic mount. Never seen a copper oxide on a motor bike, usually a Selenium type on Bantams and Villiers. My Honda 90 had an encapsulated bridge rec, wonderful machines were the 70 & 90. John
|Thread: New Workshop Progress|
SWA is the way to go, easy to terminate and you don't need stocks and dies or a bender either. Some wholesaler have a lot of short ends, cheap, to get rid of, and you might come across some good but used. John.
|Thread: WARCO MAJOR QUILL REMOVAL|
I have an RDM 350 round column table top mill/drill, there was a series of articles in ME in December 1980 on how to get over the alignment problem when raising or lowering the head. I am interested to read more about Edwin Whites idea on the same problem I think RDM mill/drills are known as Rong-Fu in other parts of the World. John
|Thread: Electronic Lead Screw Project|
Hello John, is it a Huanyang inverter which has failed ? I have read with interest how some other members / readers are suggesting Huanyang are not up to expected standards, but I have never heard of a failure in real life. Could you be the one. John
