Hi Pete, yes I did anneal it first. I milled 'V' grooves to leave about 15 thou to bend then annealed the lot. One of the legs broke off when I bent it and when I heated the rest up to solder the joints, the bracket keeled over as the remaining bends moved when the heat was applied. I did smile to myself as anyone watching would have thought Laurel and Hardy were in town!
I eventually got a bracket from it but it was a lot of faffing around and does not look good. I will have some pictures on my Lamb build on Sunday!
Thanks for the advice!
Tim

With my unexpected day off I thought I would have a crack at sand casting some small components, but as I suspected the original is just too fiddy and the sand sticks. Back to the drawing board

Do you mean aluminum castings? I use poly.... foame for my castings, it works really well, and you can make one off very complicated castings. plenty of info on youtube.

My good friend Bob gave me some 5/32" grey plastic to cover all my benches with, and this provided the opportunity for a spring clean and a little reorganisation! I've taken down the 1/16" scale sectional Brit drawing which has enabled me to move the sagging bookshelf high onto the far wall, put up a new projects shelf - it's nearly full!- and generally use the space a little better. It's a bit tatty now, but does anyone want the Brit drawing? It is spot on accurate! John Before: WP_20170630_12_26_03_Rich by inkaboat, on Flickr After. 20190329_162256[1] by inkaboat, on Flickr

I've been drilling and tapping Locomotion's boiler shell for blind bushes. This doesn't sound much, but the boiler is in fact the chassis, so everything is hung on the boiler. The original design used thickening plates inside the shell, with screws from outside, caulked with Comsol. I wasn't keen on this, neither was the boiler inspector, so I've substituted blind bushes instead, threaded into the shell and silver soldered, though I still kept the thickening plates in high load areas such as where the axleboxes fit on. At last count, its 48 blind bushes, 8 ordinary bushes for safety valves, blowdown valve, water gauge, feed clacks and pressure gauge tapping, plus 4 large diameter gunmetal bushes. The shell looks more like a collender than a boiler at the moment, and I'm only half way through!

Been co-panellist at the IMeche today interviewing candidates for election to Member. I have been meaning to do this ages. In a cabinet on one of the stairs in birdcage walk is an exquisite 3.5 inch gauge Caledonian Railway loco. I remembered to take some pictures of it and I thought the membership may like to see what it looks like. Excuse the quality the light was not good. hope you enjoy it Dave IMG_0860 by Dave Smith, on Flickr IMG_0861 by Dave Smith, on Flickr IMG_0866 by Dave Smith, on Flickr IMG_0865 by Dave Smith, on Flickr IMG_0862 by Dave Smith, on Flickr IMG_0863 by Dave Smith, on Flickr IMG_0864 by Dave Smith, on Flickr

I managed to win a Stuart boiler today on eBay, following SimplyLoco's lead I plan to make it nice and mount it for my Stuart 10H. It's just the boiler, so I've got quite a bit of platework and fittings etc to make. Should be good practise.

I don't think that I have ever mounted an old boiler before: whatever gave you that idea? 😊 John

In a cabinet on one of the stairs in birdcage walk is an exquisite 3.5 inch gauge Caledonian Railway loco. That is one of the nicest things about going to Birdcage Walk for lectures or training. Always give it a glance on the way down to sign in or when heading back up to the main lecture theatre. Regards, Dan

Thank you Kipford for posting those lovely pics of the WH Dearden loco.
From memory, it was a 3.5"g 'Dunalastair', and was the first 'construction series' around 1901 in ME, and the only loco construction series until LBSC started his articles on 'Ayesha' in 2.5"g in 1924.
It had valves between the inside cylinders, as per prototype. Quite something in 3.5"g!
I've never seen pics of it of such quality before, so that has made my day!
Cheers,
Julian

Hello Julian.....So just who was this WH Dearden then ??..quite a builder by all accounts..
It looks like it's made out of brushed Stainless, but that could be just a tick of the camera..........probably draw-filing as seen up close maybe ??

I did try googling his name and various variations (I can't read the script very well) but nothing came up to speak of.

Hi Dave, Thanks for posting those photos, it sure looks like a stunning model! I just happen to have copies of the ME from around then (well sure they are I picked up several years worth from the very early days of ME) so will have a look & see if there is any other info
Cheers Kerrin

W H Dearden appears to have been an active contributor to Model Engineer Magazine in the very early 1900s. Search his name here. In late 1906 he appears to have set-up in business "as a model maker and experimental engineer, and will be pleased to receive enquiries from any of our readers requiring work of this nature. Mr Dearden, for the past fourteen years has been in the service of the Projectile Company, of Battersea, as gauge and tool maker, doing the very highest class of finest mechanical work, and he will be well known to our readers as a Gold Medallist of the Society of Model Engineers, and the winner of several other medals and prizes in model-making competitions." Source: Model Engineer Magazine, Volume 15, issue 284, October 4 1906, page 335, "News of the Trade".Some details of the construction of his locomotive were covered in Model Engineer Magazine in 1913, Volume 28, issue 619, page 217. The construction series for the Dunalastair locomotive by E L Pearce commenced in Model Engineer in 1901, volume 4, issue, 42, page 57. The 3 1/2" gauge model had a boiler pressure of 50 lbs per sq in and an estimated tractive effort (at 80% full pressure) of 6 2/3 lbs, so not a 'passenger hauler'. Regards, Phil
