Flying Scotsman Mainframes Part 2, Frame Stays Most of the parts seen in the next few entries will be laser cut parts as supplied by Malcolm High of Model Engineers Laser. these will begin with CAD work
Flying Scotsman Engine: Mainframes Part 1 The main frames are were we begin properly on the engine itself and I have to say that Don's drawings are more or less a true scale miniature of the
Flying Scotsman Engine: Bogie Shock Absorbers On to the bogie spring set-up, again, lots more work involved here and unlike any of the other suspension components on a Gresley Pacific, these are helical springs rather than
Flying Scotsman Engine: Bogie Axle Boxes Ah the axleboxes, I have to admit to really enjoying making these things, a hell of a lot of work when talking 'split boxes' but well worth the extra effort
Flying Scotsman Engine: Bogie Wheels I was very much looking forward to doing these wheels, things begin to take shape when sitting on their wheels, even it is only those for the front bogie. There's
Flying Scotsman Engine: Bogie yoke Continuing the build on the bogie I moved onto the yoke, overall dimensions are 2 3/8 x 1 5/8 with the spigot being 1" wide to fit the
Flying Scotsman Engine: Bogie Centre Stay There's a lot of work in this part, not such in machining the casting itself, but in making all the spring control parts that fit within it. I have tried
Flying Scotsman The Engine: work begins, Bogie Frames So where to start?, well I thought I'd start with an easy item, the bogie truck, did I say easy??? I had read Don's "words and music" completely a number
Flying Scotsman Tender: some extra detail and painting of the chassis. This is a big update, this will be where I leave the tender for now until the final painting session once the loco is ready for the same. There's a
Flying Scotsman Tender: Steps and Water valve piping This update is going to look a bit strange as some bits may look 'out of step' for example I begin covering the fabrication of the steps and then the
Flying Scotsman Tender: Brake cylinder brackets and a few bits and pieces. Brake cylinder support brackets, I've deviated from Don again ( making a habit of that) both in method and design. Don states to bend up the brackets from 1"x 1/
Flying Scotsman Tender: Vacuum cylinders and relief valves Dons 'Doncaster' has 4 cylinders , 2 each for the loco and tender. these are vacuum controlled and incorporate an auto-braking system. This again is as per prototype. I have tried
Flying Scotsman Tender: Brake vacuum reservoir tank The vacuum brake reservoir stores enough vacuum to enable the brakes to operate, the brakes on this locomotive are the auto-brake system, that is, if the locomotive becomes separated from
Flying Scotsman Tender: water gauge This was a fun thing to make, again it's fully functional and follows the same principles as the prototype. Of course it won't function exactly as full size as water
Flying Scotsman Tender: Hook and Screw coupling I started to follow Dons method for making the hook which basically starts off as a 4 1/2 x 1 x 3/16 flat BMS which you turn down
Flying Scotsman Tender: Shock Absorbers There are in fact 32 shock absorbers on Gresley's Pacific and I guess I should have built them all at once. However on further reading about FS it's come to
Flying Scotsman Tender: suspension leaf springs and buckles In this update I'm going to describe the fabrication of the leaf springs and I'd like to start by pointing out that the thickness for the springs as given by
Flying Scotsman Tender: Suspension spring hangers spring hangers.. ahh.. bless the little buggers, these take a fair bit of work resulting in soar fingers, you'll probably hear me say this a lot as the build progresses.
Flying Scotsman Tender: Buffer stocks/heads and Guard irons. These are made from solid and begin life as lumps of steel cut to 3" lengths ready for machining the buffer stocks. I'm not sure what steel this was as
Flying Scotsman Tender: Handbrake I have probably said a number of times so far, how impressed I am with Don's design and how accurate it is in following the prototype, the handbrake is just
Flying Scotsman Tender: Brake shaft construction Today I have details of the brake shaft construction, this one item took me two days. So much work for a relatively small yet important part of the tenders braking
Flying Scotsman Tender: Brake Hanger stretcher beams and pins. Continuing with the brakes here we have the last laser cut part from Malcolm's brake hanger kit. This is the front brake beam, if you look closely you'll spot the
Flying Scotsman Tender: Brake Hanger brackets and brake shoes. These are the brake hangers, they are laser cut items from Model Engineers Laser. There are 8 in total, 2 front which are the ones with the boot leg shape
Flying Scotsman Tender: Suspension and brake hanger brackets. Ok, so we now move onto both the spring hanger and brake hanger brackets. The brakes and suspension components will be filling these blog pages on and off for a
Flying Scotsman Tender: axle box oil trays and covers Although the oil trays are relatively simple things to make they do take a fair bit of work/time to complete and some bits are very small which doesn't help
