|Thread: VFD/Lathe fault|
No i haven't a Jaguar cub but I have made a MOTOR folder / book for club members, as a reference for when I expire. I thought if I had a copy of Jaguar cub I would add it to the folder ,thinking it might be useful to a member in the future.
Several years ago I bought a pre owned Omeron inverter at an auto jumble sale, the seller said it worked all OK. But when wanted speed control it wouldn't, After doing every thing I could think of,I phone Omeron,, their technical support, man was so very helpful. I was too quick using the push buttons, he said, press and pause and when I did, press and pause, every thing worked. I was very grateful / happy. John
Hello Ron, is it possible for you to post a copy of the email from transwave here for other person possible use in the future, one never knows. John
|Thread: Myford ML7 Trileva two speed|
I have several old American books dated 1946 on rewinding motors, and in one it describes a 2 speed single phase motor with two sets of winding for each speed. No mention of a capacitor though. Should any one be interested in motors of all types. I can recommend "Electric Motor Repair" editor Robert Rosenburg and "Armature Winding and Motor Repair" by Daniel H Braymer ,there a few British ones as well but not so comprehensive. John
|Thread: Leadscrew suppliers|
If you do a search for lead screws , I think you might find some thing like Humber Engineering or Hull Engineering, both ring a bell but can't be sure. Some time ago some here ,spoke of an engineering company in the Hull area who stock lead screws and he was a satisfied customer. John
|Thread: Colchester Student Mk1 Won't Start|
Hello Richard, a friend of mine died recently and another friend and me have been clearing his workshop. There is a LOT of measuring equipment and other materials / tooling available in Scarborough. If interested at all, send me a PM with a phone number or email address. John
|Thread: component tester|
I suggest you post a request for assistance on Vintage Radio, I do know several members have bought similar devices as I have. They are very good, but I'm unable to be of assistance.John
|Thread: choosing a lathe|
Join a Model engineering club, I'm sure there are some in NI, ( have a look in the back pages of Model engineer club details) then hopefully a member or two will let you visit their workshop and see there lathe/set up. there might just be a workshop sale on the go. John
|Thread: Myford clutch|

|Thread: Mig welder|
Can any one supply me with a picture of the innards of a BOC Migmaster Turbo 130 or Cerboro Turbo 130 which apparently are one and the same welder. Also, I would like a copy of the circuit diagram in particular the wire drive motor speed controller. There is a small transistor on the pcb in a very inaccessible location and I can't see its number or letters. John
|Thread: Warco WM250 I have killed it|
Hello Murray, try Grizzly in USA for their equivalent machine. Apparently they have very good and clear instruction manuals unlike British dealers flimsy ones. John
|Thread: Bandsaw coolant pump help|
Most likely a faulty capacitor. However,some of these small motors have in effect three coils, a pair are connected in series across the 230 volt supply. the third coil is connected to the centre tap of the pair (TEE shape) and the capacitor is connected to the third coil open end. Now, one end of the two in series is connected to the second capacitor terminal and to the 230 volt supply. The other end of the pair ( second) is also connected to the 230 volt supply.The Capacitor and the third coil are in series. This means the capacitor can have a lower working voltage and be cheaper.John
|Thread: Riveted Linked Vee Belt|
I've used a lot and there isn't an easy way, its a knack one acquires. I use a small slightly bent screw driver as a lever. I'm told in former times a tool called a button huck was used. Both Brammer, and Fenner used to make it so maybe a look on their sites might bring some thing up. John
|Thread: Box-Shifters and Quality Assurance|
I think some one else bought Bardwell entire stock and are doing mail order, unfortunely I can't remember the new owners details. If you have a look on "Vintage Radio" you may find the new owners details.
|Thread: Pre-load of new bearings|
All very interesting, does anyone know what happened to Ransome & Marles bearing manufactures of Newark Notts. Maybe another housing estate by now. John
|Thread: Myford Mk1 Super 7 restoration|
I has the same early type Super 7 with early type gear box. I like Werner found that some of the internal gears had teeth missing, on contacting the original Myford they said, they no longer had spares for the early type gear box. I looked in HPC gear catalogue and found they had them on stock, unfortunately with a bigger bore. I bought the gears, increased the bored even more, then shrunk in a piece of prepared bar to fit, and then bored it to size when cool. I hope you don't need this information. John
In former times when motor bikes had magnetos, some magnetos would require re magnetizing to obtain a good spark. You could take the magneto to the motor bike repairer and have it fixed, a ten minute job. Has any readers got details technical or otherwise of re magnetising magnetos or other articles where a permanent magnet is used, such as in an analogue multi meters (Avo) and where its internal magnet may have lost some of its magnetism. I'm interested in making re magnetiser and how its used. John
|Thread: Electrical conducting paint|
I think I used my 100 watt soldering iron, maybe it was 80 or 90. I warmed up the connector first, then quick dab, job done.I also remember buying some expensive Silver conducting paint, from I think Radio spares now RS for fail rear widow heater and that worked. John
|Thread: Neilson air line fittings|
I've looked on the net for Neilson air line fitting to match up with my existing ones, other makes won't seal properly. Can some one recommend a seller. John
|Thread: VFD & Inverter questions|
I'm 100% with steve above, why not just help some one in need. I have three different makes of inverters, all pre owned as the car salesman says, and have received some helpful setting up advice here, I'm pleased to say. John
|Thread: Motor Starters|
If you send a picture, I might be able to help. John
