Thread: Anyone know about Mitsubishi plcs
02/12/2019 21:19:44


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

02/12/2019 21:14:43


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

just coincidence?

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?

Did you start the lathe with the red ball hanging over the end of the splash tray and start power feeding towards the chuck?

23/11/2019 21:46:04


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

23/11/2019 11:42:02

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
09/11/2019 13:07:15

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 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
06/11/2019 11:18:44

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

dsc01847 (medium).jpg

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
16/10/2019 20:53:08


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

16/10/2019 16:10:09


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

16/10/2019 12:36:31

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
15/10/2019 10:43:37


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
09/10/2019 06:46:35

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.
