sir douglas Posted March 18, 2017 Author Share Posted March 18, 2017 (edited) The motors 5050 offered to me are too small except for one that i somehow killed while testing it but a very good slow running motor has been scavanged from a rejected point motor gearbox courtesy of Jamie thunderchild (25) by Sam, on Flickr just as i was sitting down at the work bench dad went to bed (he works nights) so i couldnt cut out the nickel sheet for the motor mounting plate on the gearbox, so instead i did a few quieter things like cutting out the motor hole in the footplate and gluing on the bufferbeams thunderchild (24) by Sam, on Flickr now i know the size of the hole to work around, I can start building up the body Edited March 18, 2017 by sir douglas 5 Link to post Share on other sites More sharing options...
sir douglas Posted March 18, 2017 Author Share Posted March 18, 2017 Another day ups & downs as usual. this afternoon, i got the motor plate cut out and drilled, a little bit of fettling later here is the usual clip of the running gearbox https://flic.kr/p/SPVSbL I was taking off one of the wheel sets to thread on the gearbox into the chassis, but while i was pulling one of the wheels off, the crankpin bolt stabbed my thumb and it bent so i tried to straighten the crankpin but it snapped (!). Instead of ordering spares from Slaters and having to wait for it, im using some other crankpins ive got that was going to be used on my O16.5, i cant remember where i bought them. they have a thin thread to screw the con rod bushes onto and a larger thread to screw into the wheel, and in hindsight these crank pins will work out better for building up the motion. ive had to do some modifying of the con rods to fit. the slaters bushes were soldered into the rods and drilled out for the new bushes thunderchild (27) by Sam, on Flickr Wheels bak n and con rods on, the method for retaining the gearbox to stop it turning in the chassis is just like on the Kitson but with a slight difference. On the Kitson a brass rod passes through holes in the gearbox and the chassis frames and is bent round at both ends, this is the same but because there wasnt anywhere i could see to pass the rod through without obstructions so instead the rod passes through the chassis just infront of the gearbox and a piec of brass was soldered onto the side of the gearbox with a hole drilled out of the other end for the rod to pass through thunderchild (28) by Sam, on Flickr apart from the pick ups, i now have a running chassis all the parts sat together thunderchild (29) by Sam, on Flickr 3 Link to post Share on other sites More sharing options...
Tove Posted March 19, 2017 Share Posted March 19, 2017 What a cracking little article on the 'Corringham' railway Sam,(post #379) Sound`s like that would make a good layout,especially with the short length of the line. Not that i`m going to think about it,but the 1950 take over period sound`s like that would be ideal period...perhaps,overgrown track, run down stock ummm.....

sir douglas Posted March 20, 2017 Author Share Posted March 20, 2017 Yesterday i got the pick ups on and the chassis running Thunderchild (38) by Sam, on Flickr Thunderchild (39) by Sam, on Flickr This morning, cut and drilled the cylinder ends and the back piece to join them, here the parts assembled, the piston tube is temporarily fitted to align the holes while the glue dries Thunderchild (37) by Sam, on Flickr 6 Link to post Share on other sites More sharing options...
sir douglas Posted March 21, 2017 Author Share Posted March 21, 2017 (edited) mounting the cylinders today. 2 short lengths of steel rod superglued into holes in the back of the cylinder which slot into the 2 holes in the frames and a nut & bolt goes through inbetween them Thunderchild (40) by Sam, on Flickr the countersunk bolt head sit in some layers of styrene ply'd onto the inside of the cylinder block, eventually the bolt will be captive by more layers over the top of the head Thunderchild (41) by Sam, on Flickr washer and nut goes into the bolt thread inside the chassis, this will make the cylinders easily removable Thunderchild (42) by Sam, on Flickr right hand side cylinder fitted Thunderchild (43) by Sam, on Flickr Thunderchild (44) by Sam, on Flickr and left hand side fitted Thunderchild (45) by Sam, on Flickr Edited March 21, 2017 by sir douglas 8 Link to post Share on other sites More sharing options...

sir douglas Posted March 22, 2017 Author Share Posted March 22, 2017 After the bolt heads in the cylinders were made captive by covering them with a layer of styrene, the piston tubes could be superglued in (thunderchild (46) by Sam, on Flickr With the piston tubes in, the cylinder front ends could be glued on (thunderchild (47) by Sam, on Flickr the slide bars are 1.5mm square brass rod, when i bought it i also got a box section to fit on it for the crosshead. A bit more of it has been used as a dry fit slot for the slide bars in the cylinder block. the hole was drilled and opened square with the dremel and the box section superglued in. Also the slide bars have been cut, below shows a test fit (thunderchild (48) by Sam, on Flickr but the test fit showed that there wasnt going to be enough room for the crosshead because the slide bar was touching the crankpin, so the cylinders have been packed out by 1mm each (thunderchild (49) by Sam, on Flickr Its not quite clear but below shows the right hand side from the front and shows that there is now a reasonable gap between the slide bar and crankpin (thunderchild (50) by Sam, on Flickr 5 Link to post Share on other sites More sharing options...
sir douglas Posted March 23, 2017 Author Share Posted March 23, 2017 (edited) A goal I had set myself was to have all the motion finished and running before i went away to london, which i have now done and the loco is boxed up ready to go Since im not yet used to working with brass and doing delicate soldering, the fiddliest soldering ive ever done has been doing these motion brackets Thunderchild (51) by Sam, on Flickr motion brackets screwed on and soldered the slide bars on Thunderchild (52) by Sam, on Flickr Thunderchild (53) by Sam, on Flickr The crosshead was the next fiddliest soldering ive ever done after the brackets Thunderchild (55) by Sam, on Flickr test fit of a crosshead Thunderchild (56) by Sam, on Flickr A problem with my measurements has meant that i had to cut new rods because they were a bit too short, old ones top and new ones bottom, i still needed to drill out the big end to un solder the bushes from the old and put them into the new Thunderchild (58) by Sam, on Flickr with the bushes in, the rods were put onto the crosshead with the redundant crankpin nut & bolts Thunderchild (59) by Sam, on Flickr motion fitted to the loco and here is a test run video with the loco upside down with jump leads https://flic.kr/p/SC5ikN test run on Deffors under load of some lead strip, the roll of tape is just to sit the lead over the middle of the wheel base https://flic.kr/p/SC5AzC motion brackets painted over with Tamiya black Thunderchild (63) by Sam, on Flickr Edited March 23, 2017 by sir douglas 9 Link to post Share on other sites More sharing options...

sir douglas Posted March 28, 2017 Author Share Posted March 28, 2017 Next up is are the Cylinder wrappers and the boiler cylinder wrappers Thunderchild (66) by Sam, on Flickr Thunderchild (65) by Sam, on Flickr The boiler, I was trying to find a tube the right diameter but couldnt so instead i looked for something the right diameter to wrap styrene around into a tube, one of the options was to raid the lego box for it which i found 3 pulleys and if i put them onto a lego shaft i can wrap the styrene on. The flanges of the pulleys needed taking off but i decided that two of the rims should be left on to go on the ends for the styrene to sit inbetween and the middle pulley will have both flanges removed Thunderchild (64) by Sam, on Flickr the styrene sheet was cut and superglued in and held on tight with electrical tape Thunderchild (67) by Sam, on Flickr and after the glue dried and the tape removed. the bend ridges will eventually be sanded off Thunderchild (71) by Sam, on Flickr i was going to do the backhead some time ago but needed to leave until i know for sure what diameter the boiler will be so the firebox can match it, with the above done i can start Thunderchild (69) by Sam, on Flickr Thunderchild (68) by Sam, on Flickr and sat in place Thunderchild (70) by Sam, on Flickr 11 Link to post Share on other sites More sharing options...

sir douglas Posted March 29, 2017 Author Share Posted March 29, 2017 not clear because of camera flash (and the button to turn it off doesnt work) but here is the back head now with the layer built up and filed round for the brass surround Thunderchild (73) by Sam, on Flickr Thunderchild (72) by Sam, on Flickr painting the cylinders, this is after painting but i then had to sand it down a bit to even the surface before doing another coat Thunderchild (74) by Sam, on Flickr boiler and smokebox now glued down, ive been trying to sand down the fold ridges but i think instead I'll build up a few layers of undercoat and then sand it down Thunderchild (76) by Sam, on Flickr An under side view of the boiler showing the cut out for the motor and the middle lego pulley that had to be cut in half Thunderchild (77) by Sam, on Flickr the inner sides of the side tanks are now on, you can see the spacers that were put in cut out of styrene off cuts, before the side went on, a housing was put in around the inside of the trapezoid gap, the inner side of the tank doesnt has a corresponding gap like on the prototype which you can see all the way through both gaps but i want to try to hide the motor as much as possible so you cant see it through the gaps Thunderchild (75) by Sam, on Flickr there now has to be a certain order of events for it to go the way i want, to be able to fill the tanks with lead, it needs to be stuck down the footplate but that also means gluing down the cab but i need to leave that until after ive finished and fitted the backhead and the other in cab details. so while i cant do much more on the body until after that, i can work on the chassis like the brake gear, trailing wheels, guard irons, drain cocks and cab steps for example 5 Link to post Share on other sites More sharing options...
sir douglas Posted March 29, 2017 Author Share Posted March 29, 2017 (edited) i recently came across a very good quality photo on Flickr of a Kerr Stuart in Egypt that looks like its also a Waterloo class and the quality of the detail when you zoom in is amazing, theres a few dteails i wasnt able o see on the Kynite photos hich are scrip and clear on this like the linkages between the valve piston and the inside valve gear, the balance pipe for the tanks and the pattern of the trailing wheels. an obvios oddity is the smokebox but also that the drain cock pipes go in towards the centre instead of forwards. some notable differences with kyite is that this doesnt have the curved corners to the cab and tanks like on Kynite but has a hand rail on the end of the tank, Also the angles T section brackets between the footplate and bufferbeams is something i'd like to copy https://flic.kr/p/QCAcrF and inserted here but go through the link to try the zoom Egypt Railways - Egyptian Railway Administration 0-4-2 steam locomotive (Kerr, Stuart & Co - Works Nr. 452, 1897) by Historical Railway Images, on Flickr Edited March 29, 2017 by sir douglas 1 Link to post Share on other sites More sharing options...
5050 Posted March 30, 2017 Share Posted March 30, 2017 Looks like the 'board' behind the lower part of the cab side handrails is an extra piece as it overlaps the tank side slightly? Possibly to keep the lumps of coal in place and stop them falling out - as you said. Link to post Share on other sites More sharing options...
sir douglas Posted March 30, 2017 Author Share Posted March 30, 2017 (edited) A bit of the backhead and the brake gear today On my previous locos the brake shoes were fitted with a big enough gap from the wheel tread to allow for the flanges if i needed to remove the wheels but this time i want a realistic tight gap so the shoes will have to be removable, so they have been made to screw onto styrene blocks on the chassis. Below, the 2mm³ blocks are to the left of the wheels and as this is the left hand side, they are forward of them, next to the chassis are the brakes themselves which are 1mm styrene cut to profile and the usual bolt heads on either end Thunderchild (79) by Sam, on Flickr Left hand brakes screwed on Thunderchild (80) by Sam, on Flickr On the backhead, a start has been made with the fire hole doors, their runners and the regulator stuffing box Thunderchild (81) by Sam, on Flickr Edited March 30, 2017 by sir douglas 12 Link to post Share on other sites More sharing options...
sir douglas Posted March 31, 2017 Author Share Posted March 31, 2017 (edited) Trailing Wheels For those who have forgotten, I'll first go back over making the wheels. Back in January The wheels were taken from a Hornby Castle front bogie and put onto a slaters wagon axle thunderchild by Sam, on Flickr Thunderchild (4) by Sam, on Flickr Then they were then filled with miliput and today the wheel faces were milled out to create the reccess and the ovals drilled out, Although the holes are supposed to be D shaped, i think only anybody who reads this thread ill be able to notice the diffrence Thunderchild (82) by Sam, on Flickr and painted Thunderchild (83) by Sam, on Flickr Edited March 31, 2017 by sir douglas 4 Link to post Share on other sites More sharing options...
sir douglas Posted April 4, 2017 Author Share Posted April 4, 2017 been a bit slow at the moment on Thunderchilld, i haven't worked on it for few days now as im still pondering how to attach and articulate the trailing wheel since i cant see apony arm in the photos so i think it had a vertical articulation and ive not quite got the enthusiasm right now to do small fiddly bits like the backhead fittings, but instead im working on other things like a second hand white metal wagon bought at ally pally and some repairs to the skytrex wagons which have suffered from hook spring problems after heavy usage on Green Ayre over that weekend.

844fan Posted April 6, 2017 Share Posted April 6, 2017 Looking good Sam my friend. You know even though her name is taken from a drama I just can't help but want to see her rolling along once finished with thr Thunderbirds theme playing. It would really suit her and her namesake if you ask me. Also to be clear I'm talking about the theme sans the countdown. I'm not sure if you've said elsewhere but if I may ask what color do you plan for her livery? I think she would look quite fetching in a Red with black stripes and white lining around the black. Just my Ten Cents my friend looking forward to more. Link to post Share on other sites More sharing options...
