			The implosion-sheild is done. This is both to protect users in the case of catastrophic failure of the glass bell-jar, and protect the bell-jar from users and passers-by in the mixed usage workshop.

			The bell-jar will be padlocked down as an access-control measure.

			We're still in need of vacuum gauges, feedthrus and vacuum hose to connect the backing pump. Getting close now!

			'''''19-02-2014'''''

			Long-overdue update to the wiki page.

			The diffusion pump has been serviced and cleaned. The cooling jacket is leak-free. It appears to have previously gone UTA catastrophically while at operating temperature, as it contained glass debris and burnt-on pump oil residue. It has been temporarily sealed for dust protection and returned to the equipment trolley.
			The next step is to complete the radiator & fan enclosure to get the pump cooling-loop operational.

			To go to a bell-jar based design, circles of billet aluminium 13" dia are available from Alauminium warehouse, but will need facing on a large lathe. A used gas cylinder has been donated to serve as bell-jar. Suitable seals are approximatly £30.
			The trolley will likely need re-designing eventually.

			Inline temperature sensor, flow-sensor, pumps, etc.. all available from PC water-cooling suppliers.

			Most of the welding is done, but we ran out of welding gas. Need more before transformer mounts can be done.
			Dry-fitting has begun, though will need short 5/16ths 24tpi Whitworth bolts to connect to chamber base.

			Backing pump has been mounted on anti-vibration feet.

			Welds will need grinding flat and re-doing in places once dry-fit of all parts is done and setup proved.

			'''''19-03-2012'''''

			Have collected a Pirani/Penning gauge controller. Purchased from ebay for £5, plus packet of chips for ride to collection. Edwards Model 4, approximate age of existing gauge heads. Should be compatible. Supports two pirani and one penning head. Not rack/panel-mount, but should do the job very nicely. Will need compatible mains plug.

			Likewise purchased some mixed Speedivac fittings (£11 including postage) that should make building up the vacuum pipework a lot nicer (avoiding using the home-made joints is a bonus).

			Also donated a water-flow meter. Currently runs on 24v relay, but has fitting for hall-sensor control, so suggest gutting of stock electronics and wiring directly into control systems.
