As said by others that type of switch does have a tendency to malfunction, but if you have overcome this with years of use carry on.

The isolator wouldn't be installed now in an industrial situation as there is no provision to Lock Off for machine maintenance.

A new enclosed 16A TP IP65 rotary isolator costs around £15 so perhaps replacing would be good advice.

Hi Tom

If you can turn a ring of a thickness to suit the backplate register with a 72mm OD and 52mm ID you could use a 100mm diameter ER40 chuck backplate, this would enable any length to pass into the spindle.
You will have to drill the fixing holes to suit the spindle fixings PCD of 75mm.

If the bottom surface of the backplate is true to the front face then you could drill the fixing holes to suit your spindle and bolt direct but using a DTI to check it is truly centered before and after final tightening.
This would likely only be the way to go if the lathe was always used with the ER40 chuck.

For an electronic edge finder the American firm PEC make 2 versions, I have one with 1/2" body and 0.200" parallel tip.
Only problem you may encounter there is no spring protection on the working tip so you always have to use with care.

Gives consistent indication in use and instructions say use it in a stationary spindle but I admit to using mine at about 200rpm.

Tony English is a very reliable and well established eBay trader, lots of good gear at fairly low prices, fast postage and good packing.

Why risk messing up a good spindle when it is far simpler to modify a tooling arbor, I used an 0V for several years with a Clarkson Autolock and a 1/2" drill, the drill was on a modified arbor.
I have a pattern somewhere taken from the spindle nose which I used to get exact dimensions for a machined arbor, I will look for it later.

So these days I guess an ER type chuck would be the choice because of the extra versatility, an R8 shank would be a good donor for the R0 needed.

I never worried about using collets to get more clearance from spindle to table, it was always more than adequate even with a rotary table or dividing head fitted.

Agree always worth visiting Forncett Steam Museum but the number of models displayed in the tea room was disappointing compared with earlier years, good spread of model steam engines in full steam and running in the field.

The tour of working engines compared by Rowan is always a delight, such dedication to a project is hard to find and his enthuisiasm is catching.
Bill was definitely there in brown overalls as promised and he also had his model engine on display in the back of his van.
Andrew was displaying some of the parts made for his steam engines which were well worth inspecting hands on to see some excellent machining.

There were some other displays of interest but I didn't note the names.

If you are paid 4 weekly Direct to a Bank account in arrears then the above is not true unless payment is for any period after death.

In adition to those 30 taper shanks John listed is SKF30, this type has no provision for drive dogs and relies on the taper to transmit power, not equipped for draw bar use but is designed for retention by pull stud so is quick change tooling, standard equipment on the Emco F1 cnc milling machine and other Emco machines.
It does have a vee groove to allow the use of auto tool changing.

I don't doubt it is a TP&N supply as that was the norm during the 1960's and 70's in domestic premises that had night storage heaters fitted, it was to help ensure a reasonable balanced load on phases.

Emgee

What type of power supply do you have coming into the service fuse ?
Is it PME, sheath earth from underground supply or overhead with no earthing supplied by the provider ?

Do you just want to have a 3 phase (+N) supply sufficient to power the 1HP motor ?

Emgee

Hi Carl

Do you need a Foot mount or Flange mounted motor, also what speed 1400 or 2800 and does the shaft diameter have to be a specific diameter ?

Emgee

If phase rotation is important it's always best to confirm the 3 phase conductors ID is correct using a Phase Sequence testing instrument before connecting/testing any 3 phase equipment that relies on correct phasing.

Definitely not classed as an armoured cable and I have fitted hundreds of the correct glands to secure the braiding, how many have you fitted. ?

Spec from Cleveland cables for SY CY and YY instrument/control cables at the following link.

For clarity SY is NOT cosidered an armoured cable, in fact some of the braided screening leaves much to be desired, it can be very widely spaced, unlike SWA where multiple steel wires cover the full circumference of the cable.

If you are planning any rallies abroad a trailer will be needed, "A" frame towing is not legal in many European countries.

With a 1200kg load on a trailer + trailer weight will put you close to if not over the MGW of the Motorhome plated weight.

The last time I saw a winder being used was by a UK Free Flight Team member at a test session prior to a World Championship. The winder acted in axial alignment with the length of the fuaelage which enables the motor to be stretched out and wound, retracting into the fuselage in stages so there are multiple what I term "knots" in the motor for maximum performance from the weight of motor.

The plans shown will place the winder at 90 degrees to the motor axis so be more difficult to use if stretching and winding as described above.

If Martin sees this he may have further helpful comment from an expert in the field.

Always worth a visit, especially on steam days where the list of engine types running on steam is impressive to say the least.

Hi Robin

Switching to another supplier charging the capped rate may prove difficult as it seems that unit costs are not available from energy suppliers at present, or at least I couldn't find any from those supplier sites visited.
