Hi ,regarding nano not working with XP machine ,the XP machine probably has a RS232 port, you could get a USB 2 to RS232 adapter from an ebay seller and try that.

Hi, most of the factory that built this has just been demolished and a housing estate is being built on the site.

Hi Maurice, so you lift 1 tonne just off the floor, then that 1 tonne is transferred to the hook and then the pivot pin in the end of the boom. i.e. the weight of an object is on whatever is holding it, imagine you have a bag of shopping on a set of scales and you pick it up, all the weight of the bag and shopping is then in your hand and the scales return to zero.

Regards Nick.

Hi,thanks for your reply.I agree with what you say.I still don’t understand how the 200kg load in Reg’s post is 1.5m in the air if it only just off the floor.If the 200kg was 1.5m in the air, the base of the load would be 1.5m from the floor,then you would move at your peril.

If it was just off the floor ,you would only need to stop it swinging. I’ve done this with a 250kg engine and gearbox

One thing to be aware of with any lifting operation using a crane, including the type under discussion, is that as soon as the load is off the floor the mass of the load is effectively at the end of the boom where the fall attaches. In the case of an engine hoist that means the mass of your 200kg lathe you're lifting is now in effect about 1.5 metres in the air. Move it at your own peril!


Hi,Could you please explain why the mass would appear to be 1.5m off the floor ,if say you’d only lifted it 10mm.

Hi, just looked at my Draper 1 tonne engine crane , I don’t think any of the steelwork is designed to fail ,every bolt is a 14mm 8.8. Why would any body design steelwork to fail when it includes a hydraulic ram.The ram will probably have a yield valve to prevent it being overloaded.

Regarding the castors it is easier to control with only 2 swivels ,think supermarket trolley with 4 swivels ,goes anywhere.

Hi, if you use a yellow site transformer ,make sure neither side of the items to be supplied are earthed,The 110volt from a site transformer is center tapped ,with center tap earthed.

MT, yes, you are right that the units should be Watt hours but the principle Laws of Thermodynamics seem to be not applicable to this new form of transport ie something no more powerful than your Super 7 motor is powering a tonne+ of car along at 60mph..

This is truly amazing.

Hi,I’ve worked it out ,I think. Car travelling at 60mph using 300Wh per mile will use 0.3 x 60 =18kWh to do 60miles.

This means an 18kW motor is needed (18kWh divided by 1h).

Then I googled power needed to keep a constant speed of 60mph this was19kW.

Please somebody correct if wrong.

Real question.

Why /how can it only take 500w/mile to propel a Tesla at 60mph when a petrol/diesel has to output 30kw to achieve the same speed, with the same weight,,tyre,,bearings/rolling/wind resistance,etc ?

300w./m and very heavy carting the pack about too...
..perhaps to do with the drive units being (almost) attached to the wheels instead of going through clutches, gear boxes and prop shafts???
Also some clever jiggery-pokery with fore and aft drive units adjustng their power proportions (as they do) during cruise and of course reharvesting braking energy when available


Hi ,please correct me if I’m wrong but shouldn’t the unit per mile be “Wh” ,I think this is were any confusion is coming from.

Anyone know the pressure at which compression fittings are no longer deemed safe? I’ve seen them fitted on vehicle hydraulic braking systems before now, but I would only use the proper flared pipe fittings in such an application.

Hi,I remember compression fittings being used on hydraulics down the pit .I used to fit them on 50mm steel pipes that carried soluble oil mixed with water at a pressure of 4000psi and 200gpm.They were often a mile in length.


Thread: What air compressor should I buy?
06/01/2021 18:36:01

Hi, use the largest diameter possible for the fixed pipe around your shed. You can use 10mm hose to go from that to your air tools.If you google air pressure loss in pipe work you will find it’s quite a lot ,especially in small diameter pipes.

Hope this helps

Hi, put “john guest air fittings” in ebay ,I think there is everything you will need.

Hi, have you tried cutting with the tool on center yet?

When I got my ML7 ,some of my cutting looked like yours, I made sure I had got EN1A steel to practice with . I’ve always used HSS tools I’d read that they are easier for beginners and old lathes.

Whenever my cutting looked like yours ,the tool was either too low or too high or it was not ground correctly.

Also the gib strips need to be setup. Try this before looking at more complicated things.

Once I’d done all this I got a good finish .

Hi, another simple test to try ,is use an extension cable and plug into house socket

I don’t mean permanent ,just to test the lathe.

Maurice, I'm interested in your scope setup. I'm familiar with the picoscope as I have one myself but never seen or used the automotive one. Are you using it with a clamp meter probe? I have a clamp meter but not for the scope. If I needed current logging I might use a current sense resistor and do it that way.

Hi, My setup consists of Picoscope 4225 and a current clamp Picoscope TA167 .The automotive scope will also run the ordinary Picoscope software.

When I got my clamp I wanted to measure starter motor current ,so I couldn’t consider a sense resistor ,it goes up to 2000A, There is a cheaper Pico clamp at £99 , this goes up to 600A, I would go for a clamp,no chance of damageing scope.

Hope this helps

I do suggest a half horse motor shouldn't ever trip a circuit breaker. Something ain't right. Earth leak would be my bet.




Hi,A 1/2 hp Brook motor on an ML7 takes nearly 50A for 100mS on start ,this will sometimes trip a domestic mcb but probably wouldn’t trip an inductive load mcb ,as previously mentioned .An earth leakage fault would trip the elcb not the mcb.



PS   If I’m writing rubbish , electrical experts please correct me.

1361d5cf-dead-44f3-933a-21eb985dcd5f.jpegHi,I’ve restored a Lucas K2F magneto ,changing internal capacitor etc ,wasn’t too difficult .

I made a simple test rig as it was hard to test it on the bike

l read somewhere that the spark needs to cross a 5mm gap in open air,which mine did.

Hope this helps


PS If you need to take the armature out ,try to find out if it will affect the magnetism in the stator, best to try to do work with armature left in place .
