|Thread: Anyone know about Mitsubishi plcs|
i’m sure that the battery’s have been totally flat for years
the dates on the ones i removed were 95 and 03
machines been switched off every night for years
no nothing.... backup or means
just strange that 2 machines in different locations have done the same within days of each other after working fine for years
we will have to get machines agents in

Has anyone any experience with Mitsubishi plcs
i have 2 machines both very different which have both got the same problem
the plc isn’t running and the prog light is flashing.
both batteries were long dead operators say they been like that for years.
i have replaced battery’s so that error has gone
both machines have operated for years perfectly well one for 25 years the other 15 years
do they lose the program? Is that what’s happened here?
|Thread: Warco GH600|
Did you start the lathe with the red ball hanging over the end of the splash tray and start power feeding towards the chuck?
the top table is the feed per rev when using the power feed or cross feed
the lower tables are when using the lead screw and half nuts
|Thread: What Did You Do Today 2019|
Yes Geoff it was I
only knew 5 mins before who the questioners would be
I was in the audience for the question time special broadcast on Friday night live and I was the first questioner very nerve wracking ...
|Thread: Scam alert|
I do get a lot of these both the amazon one and a visa saying £600 is being processed
you have to press 1 to speak to a customer service con person
Every time I do press 1 but generally the line goes dead only once has it connected to a person
this was an amazon one....she seemed surprised to be speaking to me but she just said that £39 was being taken to pay for amazon prime...to which I replied “Great I love amazon prime and I’m happy to renew”
then the line went dead
I have seen that the scam is you pressing 1 which charges you for a premium rate phone call.
I’ve checked my BT bills and there’s no sign of any premium rate numbers being charged for
I wasn’t aware that a call that you haven’t originated can be charged to you ?
|Thread: Cutting an unlisted thread on colchester student|
Just to update this thread with a solution if any else needs to do this
(I still cant get my head round it )
My thread plate
I used Brian Woods suggestion of swapping driver and driven gears
So i used the 35 as the driver and 21 tooth as driven
then with the levers set DA and the gearbox for 20tpi/1.5mm setting and the imperial/metric lever set to imperial
and leaving the half nut engaged i get a lovely 3.5mm thread s far as i can measure with a pitch gauge over 6 threads but it certainly works with commercialy availble nuts
disengage the half nuts and it wont go back on the thread previously cut
Many thanks to all that offered advice
|Thread: Anyone know about buying freehold to a house in the north|
its the church actually
They say if i dont buy within a month they will assume i dont want to and then put it on the open market
next question...... Why would some company want to buy it ?
Surely not for the privilidge of invoicing me for £6 every year
This cant go up for 800~+ years
Theres no covenents saying I have to ask to do anything to the said house
Its in a conservation area so not much scope fro extending
my opinion was much as Duncans
they can’t increase GR
they cant impose any new terms which have been zero in the last 31 years re maintenance or extension building
so if I spend another 20 years here I’m into £ 120 for the gr in that time scale rather than £3.5k with legal fees
Out of the blue a letter has arrived from my freeholder suggesting that they want to sell the freehold.
they quote a total price of £2500
plus my legal fees presumably.
My ground rent is £6.20 and it has 840 years left
Is it worth me buying it?

|Thread: VFD and screwcutting|
it may be a problem up to a shoulder but the ramp down is a product of the frequency set so at 10hz the motor will ramp down quicker than at 50hz
however you can set the ramp down to 0% or wire in a quick stop button for use whilst thread cutting and use the usuall ramp down (stop) button for normal work
|Thread: Cast iron cabinet theft|
perhaps i didnt make clear
if heres something you want rid of leave it on the pavement and it will be picked up in short time by scrap collectors
This has happened in sheffield for many years im sure also in most northern citys
Having said that Rainbows attempted to hide his prize and it still went
|Thread: Threading on Colchester triumph 7 1/2|
You should have a 21 tooth to replace the 42 tooth one
as set you can do the bottom row of threads on the chart ( the coarsest ones)
|Thread: Cast iron cabinet theft|
Oh dear Rainbows
I wouldnt leave anything outside that i wanted
I leave any scrap outside and its usually gone within the day
saves me taking to the scrap yard
|Thread: Increasing depth of field on a lens|
In a single word no
your lens is there for a very high magnification in its original use
depth of field is as you say limited
in its original use that’s not important as the micro Fitch is planer
you can adjust the aperture by an iris or stop but this will only increase dof by a small amount at the magnifications your lens has. And then you need lots more light on your subject.
|Thread: Jeremy Schmidt's Belt Grinder|
I made a similar item and built it out of 50x50 x 5mm
wouldnt have wanted any less to make a rigid structure
