|Thread: Is an internet connection essential to run Ardunio programs|
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.
|Thread: Steam engine , to start a steam engine|
Hi, most of the factory that built this has just been demolished and a housing estate is being built on the site.
|Thread: crane uprate - where would you add some metal ?|
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
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.

|Thread: Bridgeport power feed|
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.
|Thread: Fast charging anyone?|
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.

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.
|Thread: Viewing online archive|
Hi,I can still access all back issues with old mini Ipad ,using Safari and Model Engineer website.
|Thread: Disposable Gas Bottles|
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?|
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.
|Thread: Super 7 Lathe Clutch, Countershaft or Pulley Wobble|
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 .
|Thread: Myford super 7 lathe tripping consumer rcd|
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.

|Thread: Oil proof brush?|
|Thread: Useful MEW Table|
|Thread: Myford Hoover Motor|
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
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.

|Thread: Myford Lathe Identification|
Hi ,hope this helps with serial number location
|Thread: REME EMER|
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 .
