Many thanks to Toby for arranging this and driving us down there. Thanks also to Chris for letting us in.

The site was as an airfield and support site for RAF Exeter from 1941 to 1945. In 1952 an R6 Regional Government HQ control bunker was constructed on the site as part of the British Government’s ROTOR project.
The bunker, codenamed Gull Perch, was part of the Air Ministry’s project which provided complete radar cover for the UK, it was one of the UK’s largest defence project costing roughly £240 million. The high cost was due to the fact that at each ROTOR site meant that huge underground bunkers needed to be constructed as well as many reinforced surface buildings and the bunker at Hope Cove was no exception.
The semi-underground bunker is spread over roughly 3000 square meters over two floors, each floor has approximately 28 rooms, some of which have been extended with a mezzanine floor.
Hope Cove was one of five stations equipped with a type R6 bunker, along with Langtoft, St. Twynells, Treleaver and Hack Green.
In the late 1950s the site was turned in to a Regional Seat of Government by the Home Office and later became a Sub-Regional Control, Sub-Regional Headquarters and finally a Regional Government Headquarters before it was decommissioned in 1994.
For a time it was believed that the bunker was given an overhaul in the 1970s bringing it up to the standards of Hack Green, but apart from a few updates to wiring and communications, the bunker has remained pretty much unchanged since its time as a ROTOR station.

*For a Dynamic Pivot assembly, ensure that the large washer is secured between the pivot arm and nub and that the smaller washer is placed on the outside of the arm, between the bolt. For more information, please refer to the 80/20 Product Catalog:

Hello, and welcome to 80/20′s product highlight series. Today we’re going to take a look at the structural pivots. This connection method allows bars to be positioned along a wide variety of angles. They’re easy to install and are available in both fractional, metric, and are compatible across a wide range of profile series.
Now when it comes to using the structural pivot, you have a few options to choose from. The first choice is how you receive your part. The structural pivot can be purchased as stand-alone parts, or as a preassembled part, ready to install, as seen here. Now the next thing you’ll want to consider is the alignment of the pivot nub, and how it sits on the profile. The nub comes in two styles, you have the 90 degree and you have the 0 degree, the only difference being the orientation to the bar.
Now regardless of your choices, the pivot nub will need additional bolt assemblies for mounting. More information on 80/20′s recommended bolt assemblies can be found in the 80/20 product catalog. Now when it comes to installing the structural pivot, the first thing you’ll want to do is preload your hardware. Preloading not only makes it easier to install your structural pivot, but also saves time during assembly. Now the first thing I’m going to do is take the structural pivot and put one last bolt and one last T-nut in it. It’s important to know when you’re installing your T-nuts, to have the pilot projection facing downwards. Once we have that ready to go, we’ll take our first bar, and slide the pivot nub right onto it. Once we’ve found our location we’ll take our wrench, and tighten that into place. From there we are ready for our next bar, and we’ll slide it right onto the arms of the structural pivot. We’ll take our wrench and tighten down that hardware.
Now the last thing we’ll want to do is find the angle that we want our bar at. Once we’ve found that we’ll tighten down the pivot bolts. Now hopefully you found this segment on the structural pivot helpful. For more information, visit 8020.net and make sure to subscribe to future 80/20 videos, and as always, make it a great day.
