4th Resurrection of this thread, but bringing it back to the start. Andy's site has a piece on this, https://oldnblist.wordpress.com/2019/01/16/vanishing-crane/ and at the time I thought it rang a bell somewhere, now I've found it. one of two paintings (the other may be of a canal bridge in the Brownhills area but I haven't found that one yet). The painting is signed H Tunstall but not dated, possibly a local artist, but clearly shows the crane ("C" in the map on the OP). springy

self tappers have a more parallel thread body and a short taper because they are intended to secure into relatively thin material (usually metal) and drive through the material, compared to woodscrews which tend to have long taper points to pull easier into thicker material. for what these have to hold i would expect the ones you have to be fine and they are already "in stock" springy

And "woodscrews" not "self tappers"

Agree with Jen in making slotted brass screws a feature, but neatly countersunk, keeps the top surface level so that loudspeakers, books, drinking vessels etc. will sit level on the shelf, also means the screws are easy to locate if/when you do need access. You do have to line up the slots though ! springy

I hadn't noticed that, I took half a dozen pics over a couple of minutes & just chose one of them, two - the second and last are "duck like" springy

Well it has survived so far though it looks like it may have lost a little pressure. There's also a piece in today's express & star with photo, but the online link only seems to show the headline https://www.expressandstar.com/news/local-hubs/walsall/2020/11/30/canals-new-inflatable-warning/ springy

I don't do twitter but I found this earlier today - C&RT have installed a buoy in walsall basin. https://twitter.com/CRTWestMidlands/status/1329057878548877312 wonder how long it will last springy

this article has a bit more https://www.expressandstar.com/news/local-hubs/wolverhampton/2020/09/24/former-british-steel-site-bought-by-council-as-part-of-major-canalside-development-project/ springy

Working Boats in Vietnam, on the Mekong Delta from what google translate tells me, I presume its some sort of flash gate, but there must be several openings in the bridge The unladen wooden boats are fast, and there are several videos of this location https://www.youtube.com/watch?v=xH-VXhoIXH0 Tug sinks about 5 mins in https://www.youtube.com/watch?v=vwjQSQgzqSk found the location https://www.google.co.uk/maps/place/Đại+Phúc,+Càng+Long+District,+Tra+Vinh,+Vietnam/@9.9959483,106.3065841,445m/data=!3m1!1e3!4m5!3m4!1s0

IIRC you can put an extinguisher in a cupboard or locker But ..... You then have to put a large red label on the outside of the cupboard saying "fire extinguisher". springy

IIRC similar to how the electric tug in harecastle worked but for a while that also used the chain (wire rope actually i think) as one of the conductors for the power supply. springy

Found these in my collection from 1989 springy

No suggestions but a question - has it got to fit into the bed 'ole every day ? springy

what pressure is in the accumulator, have you set it to the right pressure for your pump/switch springy

looks like the one on a friends lpws3, IIRC the panel is a VDO item badged/manufactured for lister petter - so maybe a l-p parts supplier could help springy
