|Thread: Lathe query.|
Paul if you have a meter as you have checked the resistances of the windings then with the power off check for resistance on the contacts of the contacter when you press the contacts together.
then check resistance of the coil on the contactor
welcome to the forum
if you have a meter check for 415v across pairs of phases on the supply side of the contactor...so you need 3 sets of 415v
then when energised check for the same on the motor side of the contacts
|Thread: Sphere Turner|
I have the one thats in your first link sold by boffin guy on eBay
its great works well and I wouldn’t think making one any better is going to make it better to use…it does the job out of the box. And at the price he sells them for I wouldn’t go to the trouble of starting to make a copy.
if you want a ball turning jig rather than making a ball turning jig that is

Interesting use of a variable speed on a single phase induction motor too.

|Thread: Has anyone heard of this before…dopey dogs…|
My neighbour has a 1 year old jack russel type dog
it was in the garden digging down to a armoured cable and then chewed through a 2.5mm 3 core swa cable fusing the supply.
no injuries sustained but why would it do it? It was 12 inches deep in a flower bed…can the dog sense something..it’s supplying a pond pump so no great load
|Thread: Just out of interest how a angle grinder nut is made|
Here’s a angle grinder nut disassembled for your perusal
i have quite a few of these as i never seem to be able to find a peg spanner…these nuts work great …tighten as tight as you wish by hand use the tool for ages then when you want to change the disc the nut comes loose easily by hand

|Thread: How to post lithium batteries?|
Well an update
DHL had indeed xrayed the package and decided that it was too dangerous to carry so have sent it back to the seller.
as it was an overnight service may it have been flown down to somewhere more local?
so the sale has been cancelled.
i just wonder how dangerous a smallish camera battery is in a fitted foam compartment in a pelican case
|Thread: Saving the Planet … or is it ?|
I believe the tv was a special Philips model which was on a special type of standby so it was “on” immediately …the greens jumped on this as typical of all tv’s
|Thread: How to post lithium batteries?|
This back and all its Accesories are being sent in a pelican case with foam cutouts for all the parts and then in a cardboard outer box… do DHL X-ray it or perhaps open it?
I bought an digital back for a medium format camera on eBay.
seller charged me £25 for delivery he said it had cost him significantly more to post by next day with DHL.
its been caught by having 2 lithium batteries inside and is now on its way back to the seller.
is there a carrier who will accept lithium batteries?
|Thread: They see you coming|
A few years ago one daughter had bought a new smart car
first service she was presented with a bill for well over a thousand rather than the perhaps a hundred she was expecting ( car had done less than 4K on mainly motorways
the bill consisted of new discs and pads which they had fitted already
she rang me in a panic and i shot down to the dealer (main Mercedes dealer)
when i got there the service manager was saying to her it was a safety issue so they had fitted without informing her
the second i got there the service managers face dropped when i asked to see the old ones…
then there was a delay before they admitted that they had billed the wrong car..
|Thread: Newman Motor Star To Delta?|
I have run quite a few 3 phase motors in star connection straight from a VFD with no ill effects maybe a bit down on power but they ran satisfactorily ( disc sanders ,drill presses,tool post grinders)

|Thread: Silver soldering cast iron|
Stick welding rods are not expensive
a pack may be £50 but you will only use 1/2 one to a repair like Mike wants to do if that so £1 in total to repair a part which if it was available would be £50-100
if you need a rod or 2 mike let me know
I use cast iron rods (nickel) routinely in my day job repairing castings no preheating just a stick welder or after treatment…just grinding back.no failures
