    I went here when the concrete was new and I can't believe it's open again! Well done to whoever opened it up again!

    I just found you so I am behind. I want to thank you for sharing your knowledge of the equipment you find. I find it fascinating learning about all of this old equipment. Seeing these hidden places is so much fun.

    Pretty sure the two mystery machines are vacuum deposition machines for applying coatings to lenses. They should have bell jars on them.

    • @Captionmarvelous
      @Captionmarvelous 3 ปีที่แล้ว +2

      That would probably explain why they had a very high voltage transformer in one of those units? The HV AC would have been rectified to HV DC and filtered to get a high quality DC source for some electro conductive gas used in coating the lens? Note the variac to vary the amount of HV one would need. R we onto something here:)

      @machinewrangler4682 3 ปีที่แล้ว +3

      Yes, I was thinking the same. The element plug pointed out is for the diffusion pump heater high vacuum.
      And a large vacuum bell would have fitted over the top.

  • @Sixta16
    @Sixta16 3 ปีที่แล้ว +2

    30:00 That is not a lathe or winding machine, that is likely a vacuum deposition machine - to vaporize metal under high vacuum and create a thin film of metal on an object - you can create optical mirrors, filters, etc.
    The huge column in the middle of the machine is an oil diffusion pump (creates high vacuum by boiling oil inside).

    I know that place well and always understood that it was an Air Raid shelter for for Cane hill Hospital which was almost directly above it

  • @daveeboney7089
    @daveeboney7089 3 ปีที่แล้ว +7

    Great place my first thoughts where the tunnels are a hell of a lot older than WW2 they may of used them during the war but they will of made use of the tunnels that were already there. I do not know the area but i wonder if at some time in the past could a building once of stood above these tunnels🤔. If there was an asylum close to these tunnels i would think there are more sealed off underground spaced. It may be worth while looking on google earth for any unusual lumps or bumps in the surrounding fields also crop marks can often by clues. The paraffin heater, lawn mower and vacuum cleaner/hoover i remember very well from my childhood in the early 70s, the paraffin heater was all we had to heat the whole upper floor of the house and it was my job to trek to the garage about half a mile away to get the paraffin. Great video!

  • @TheRobphillips

    @ 30:13 is a machine for making class mirrors for telescopes. Convex coated very high tolerance optical mirrors.

  • @bakertam
    @bakertam 3 ปีที่แล้ว +3

    The metal discs are for polishing telescope mirrors they are concave shaped to allow the mirrors to be focused to a center point

  • @ChipGuy
    @ChipGuy 3 ปีที่แล้ว +1

    31:00 Since there are high voltage recifiers in there and "vaccum" was mentioned sputtering was one of the things these made. There was a dome on top of that carussel thing and several steps could be done in vacuum. Like finishing steps for valve production.

  • @martinsallenger5526

  • @stevewalsh1987
    @stevewalsh1987 3 ปีที่แล้ว +8

    Matt the Optics / mirrors places is another bunker not to far from this still in use by Optical Services Ltd. Its on the A22 by Kenley station.

    • @vapemasterzero7513
      @vapemasterzero7513 3 ปีที่แล้ว +1

      I understand 5 of these bunkers were built, this one was later used a s a car workshop. The Optics was another one as @stevewalsh1987 say, that is still in use, and the one matt refers to as being demolished for housing was only partially built due to poor soil. You can find out more with some investigation on sub brit. But as always, a good video matt.

    • @joewalker643
      @joewalker643 3 ปีที่แล้ว

    15:39 the hexagon shape thing is where the tooling is held on a turret lathe.

  • @andrewkiwi1
    @andrewkiwi1 3 ปีที่แล้ว +2

    Close Matt but no cigar. At 15.40 it part of a turret lathe (See ward turret lathe.) At 16.20 no its not a motor part is the bed and headstock of the lathe. The flat pulleys are for a belt drive giving 3 different speeds. At 17.14 they are the 2 pedistools it sits on. That was interesting Matt. good job.

    The black painted areas are where the telescope mirrors would be examined, flat/Matt Black paint to reduce any reflected or refracted light whatsoever when examining the mirror for warpage or distortion.

    31:11 AEG E2800C1000.. These are selenium rectifiers. 2800V and 1000mA I think. The naming was the same for some TVs but they were named like E250C85 for 250V and 85mA

  • @sampointau

    I went down this 2003/4 gulf war panic for bunkers if bombs went off their used to be a air shaft also. used to be bigger when they built the new road you lost the entrance
    used to be a place for motorcycles and bike repair on entrance when you walk round you sort off go round if the entrance is now gone you might not be able to walk hallway round

  • @markhawkins7908
    @markhawkins7908 3 ปีที่แล้ว +2

  • @krisclayton6720
    @krisclayton6720 3 ปีที่แล้ว +4

      In much of the Midwest and Colorado area those giant fields may have missile bases you'd hardly notice. Explored a abandoned titan missile base east of Denver, looks like a plain empty field. Huge bunker and 3 missile silos below. It's wild.

    At 47:30, that room is the emergency generator room. The bore to the surface would've been for fresh air in and exhaust pipe out, the concrete plinth for the generator is still evident.
    Generally placed in a seperate section at the far end of a corridor.

    When there is black carbon deposit around the fuse holders it is because the fuses have blown/melted due to over current demand or short circuit on a number of occasions not because some one set fire to the fuse holders.

    I live just down the road from this place and never knew about the bunker. My dad was a patient at Cane Hill for many years in the early 80s. I remember him telling me and my brother a few stories about the many times he tried to escape the hospital and how they found a building somewhere in the woods on the grounds. I remember him saying they hid there one night and got drunk before being caught in the morning and returned back to the Hospital. Maybe he found the bunker and the supply room. Ill never know for sure as he passed many years ago. I dont think its a hospital anymore i believe they transformed it into a private housing estate.

    There's a place more or less opposite the Kenley Hotel on Godstone rd,about 10 mins drive from here,that is still in use as a lense making place.I had to work in it many years back when i was a BT engineer.It's almost identical.I believe they used to make bomb sight lenses there during the war because it's sunk deep into the chalk cliff under Riddlesdown so there's no vibration
