Thread: micro switch
01/07/2020 13:12:43

Hmm lots availble but at high prices

Mouser came up trumps though at a reasonable price for 10 switches

but only shipping option  is £12 ( ouch)

Many thanks to Brian

Well its probably a m22.5 x1.0

big threads like that are made to suit the purpose so no standard form was used

Just search on eBay for parvalux motors with gearbox and the voltage you want

the gearbox is coaxial with these

but you can get right angled box’s too

Thread: whats this socket used for?

I did wonder if that was the case but the projector it was fitted to has a motor running the minute you plug it in and the bulb on a switch

i cant imagine the motor would have liked running on reduced voltage but maybe it wasnt meant for this projector

Very crude but works very well

a parvalux 24vdc motor with a big reduction gearbox runs at about 1 rpm

I recently bought a oldish projector which came with a 5 amp round pin plug fitted also a extension with a round pin socket to a 13 amp plug

the socket has a switch which is marked "start" in the off position and "run" in the on position

the plug has "gnome" transfer on it

it wasnt a gnome product that it was connected to

In the socket across the switch is a 213 ohm resister

any ideas what this is for ?

to keep a bulb warmed up in the off position "start" then full beans when in "run" ?img_0056.jpg

Thread: Anyone near godalming who could do a favour?
25/06/2020 13:45:46

It was a piece of equipment for repairs

he said he would post bits of it but the whole was TOO heavy to post ( 8kg)

So I’ve sent him a box and bubble wrap with a prepaid label and he’s dropping it off at local shop(hermes)

24/06/2020 13:28:48

Is there anyone near Godalming who could collect a smallish item and then post it to me?

joker of a seller insisting on collection?

all costs covered and something for doing job

Well after pulling out the drive wheel i had a closer look at it was very hard no compression at all with fingers or teeth!!

is this material called ebonite?

anyway gently rubbed the surface up with 300g emery cloth then again with the MEK

cleaned the shaft as best i could though the drive wheel touches only 5mm from where the spindle exits a oillite bush in the motor and it seemed a lot better...but still could be snappier in operation.

if i helped the solonoid it worked perfectly

checking the voltage to the solonoid it was only 15v dc but if the reverse was used another solonoid pulls in then the voltage drops to 10 v ish

delving into the wiring the motor and lamp are 240v the transformer for the control circuit and focus motor is built into the motor windings...not seen this sort of arrangement before.

the low voltage ac is fed to an old selenienium rectifier then onto the control circuits so i added a 100uf cap on the dc side and now everything works well

cleaned up all the casings which looked rough when i got it off eBay but its cleaned up great and now works fine on the 2x2 side ...just waiting for magazines for the 7x7 side.

I have an old Rollei p11 dual format projector that the drive to the slide changer is a bit weak.

the fan which is running continuously has a solonoid operated idler wheel which makes contact when drive is called for

Ive cleaned the idler with MEK (Rubber rejuvenater) but it slips when needed

would you rough up the shaft?

if so what with...wet and dry,emery etc


Its the spindle sticking out from the blue rotor

This is what i received from my Hermes.

Dear customer,

We hope that this email finds you safe and well.

We’re writing to inform you that we have recently experienced a technical issue which resulted in barcodes not generating correctly.

This happened to a very small number of parcel labels printed between 2pm on Friday 29th May and 10am on Monday 1st June. As a result, there may be a delay in getting parcels to those identified recipients.

Our systems show that you sent one or more parcels with a label impacted by this, which could result in a delay. You may wish to inform any recipients about this and that the tracking information for these parcels may be inaccurate.

We understand the inconvenience that this will cause and would like to apologise that we have not met the high standards we set ourselves on this occasion. We can assure you that the problem is now fixed and that any labels printed after 10am on the 1st June will not be affected.

Many thanks,

The Hermes Team



the label had the correct address and name on it and the regional area code (sou) for Southampton.

so what does the bar code do?

why does the parcel take 10 days now when the barcode is wrong..everything else is good ?

I have sent 100's with my hermes with no problems of their making

but last week sent one and its still at collection shop.

had an email saying that the barcodes were generated wrong so delays would be about a week

still not got there yet

they are impossible to contact by phone email they have a live chat robot who is useless

but other than this latest issue they have been great
