Welcome to the party Tim, you will need some form of dividing equipment for your orrery, add it to the list. Good Luck. Noel.

Martin has it ! BMW gearbox held on by normal bolts - EXCEPT the two at the top, there torx ! Just to F--- You up ! It didn't work, I had a set of torx keys ! JCB turbo doost diaphram, 5point torx security( pin in middle), but WHY ? Noel.

If you have the money and space then trojan 105 traction batteries BUT they are 6V or 8V so its 4 or 3 units to give 24V or 2 X 6v for 12v. Noel.

The stop button and emergency stop are a NC contact check this. Many after market NVRs are not of the highest quality or built to industrial standards. If you think the motor is at fault then check both start and run windings for continuity, then run thhe motor (lathe ) for a while and let it warm up. If the motor is OK then it can only be a simple fault. Broken wire, loose screw or terminal, incorrect wiring or a faulty NVR, check all wiring from the plug to the motor. Good Luck, Noel.

Most likely cast iron but it still can be repaired may be by brazing and filing Worth a go ! Noel..

Commercially it's done all the time, so yes. Sealing might be the only problem normally cast in or press fit then machine the valve seat. I would use 2 seperate seats. Noel.

It's in the right place, and once you can identify the thread yes ! 5/16" x 32 or 40 TPI ME would be my thought ? Noel.

What has actually broken ? The wings on the centre look good. If the anchor for the springs has failed then drilling and tapping the centre and making a new fixing may work. Bear in mind that there are 2 common motor speeds and therefore 2 switches, 2 pole and 4pole. See my earlier comment on positioning and correct operation as this could easily cook the windings if wrong. Newman were good motors it would be a shame to see it burnout for the sake of the start switch. If you know what your doing then Johns idea will work though a push button is safer,It may be cap start so the whole start circuit must be switched, you only need the start windings for less than a second in most cases. Noel.

Traction batteries would be best but leisure batteries would work ! Noel.

Dear Pauline, I would be interested and can collect. I have some from the 80s onwards but the early ones would be nice. I will send a private message. Best wishes Noel.

As Brian has said try cleaning the contacts with 320 or 400 wet or dry paper folded double in a 1/2" strip. I take it the bit you cannot get off is the pulley ? Very careful use of a gear puller may work. When fitting the centrifugal switch the position of the various parts is critical to it's proper operation = if the start windings stay on for too long then they will soon burn out. Good Luck Noel.

Martin .Tap parallel and use loctite or If the job will allow it a bonded seal or Dowty washer will make an air tight seal. Noel

As a schoolboy I bought a 1947 Vauxhall to play with using my pocket money (£3) I soon got it running and would drive it round our large garden - it was one way to stop the nettles growing. This I'm sure had a by pass filter, as do the Cummins V8-300s we use of 1960s vintage. And yes, as Howard has said, in the 60s and 70s an engine would need a rebuild at 5 or 6 thousand hours as opposed to modern engines doing 250000+ miles with ease ! How things have changed, ford 100E with metalled in rods, A and B series engines, 4.108, 4.154 6.354, in the 70s I would nearly always have at least one of these on the bench in bits !

Yes ! change the oil every year, no matter what the milage. Engines fail nowadays due to poor design or electrical issues ! Noel.

8mm X 1mm is a thread size used in some electrical fittings so not uncommon - Tracy tools do them ! Noel

Andrew has beat me to it ! I would cast them ! Noel.

Hello James, welcome to the forum, I can't help with your problem but I'm sure someone on here will be able to help. Good luck. Noel.

If the coil is of the points type there will be a gap both sides between the coil and the laminations ! If it's electronic there will only be a gap on one side. it is switched by the action of the flywheel magnet. To set it up put 2 or 3 sheets of paper between the magnet and the laminations, this will pull the mag onto the flywheel and then do up the 2 small fixing bolts and remove the paper. That will set the air gap. IF electronic you DO NOT need the points - remove them. Do NOT loose the flywheel key ! It is aluminium do not use a steel one ! If the key has even the smallest step in it replace it. Noel.

Are you sure its 4Hp not 3.5Hp ? The modern ie 80s onwards models had a electronic ignition and NO points. They were interchangeable ! one wire went to ground the other to the stop button/control. I dont think the points version has been available for decades. There were many models the numbers were stamped on the air duct over the head. If you need more info I will find my briggs manual ? Noel.

One point worthy of note is that the oil viscosity will change with temperature. Hot workshop = drips fast , cold workshop = may not drip at all ! Not the oilers fault ! Noel.

The seldom mentioned shaper would do the job ? Noel.
