Sentinel Steam Loco 7109: Full Vacuum Ahead!
http://sentinel7109.blogspot.com/2015/06/full-vacuum-ahead.html
Sentinel Steam Loco 7109. Saturday, 13 June 2015. Strictly this should be Vacuum Braking (14) Implementation (8), however, I needed a more vague heading! Two new items have appeared on top of Sentinel 7109's cab roof: to the left is Nigel's coffin and to the right is a rather fetching and elegant periscope (respectfully looking away from the coffin! A Rail-hearse in the making? The periscope, in a truncated form, will double as the vacuum ejector's exhaust outlet. Subscribe to: Post Comments (Atom).

Sentinel Steam Loco 7109: May 2015
http://sentinel7109.blogspot.com/2015_05_01_archive.html
Sentinel Steam Loco 7109. Sunday, 31 May 2015. Vacuum Braking (13) Implementation (7). Sunday May 31st 2015 has been mainly about the vacuum braking pipework but not entirely. In my last article. I'd begun to assemble the vacuum ejector pipework. Now I've pretty well completed it as shown below. Steam supply linked to the Ejector. The main work was either side of the blue pressure reducing valve (PRV). PRV, condensate drain valve and unions at either end. Comparison with usual hose attachment. The extens...

Sentinel Steam Loco 7109. Thursday, 30 July 2015. Sentinel 7109's blog will be back up and running again soon. My mother died recently and it's rather taken my mind off the usual things. Rest assured there is much going on behind the scenes with high-spec pipework, low-spec pipework, vacuum fittings and sandboxes. As the computer says. Please wait! In days gone by, the BBC would have provided an interlude as follows: https:/ www.youtube.com/watch? Links to this post. Subscribe to: Posts (Atom). Bespoke G...
