I've been a little busy of late working on the car and thus not much to show with this build but there are some things happening in the background and one such thing is the rolling road. I have now put the details on the blog, a big thank you to ED at Model engineers Laser for his superb kit. The car still has a way to go but I hope to post a proper update soon, I just find it difficult these days to concentrate on more than one thing at a time...lol Anyway, here's the RR details http://4472flyingscotsman.co.uk/rolling-road/

Hi LocoEngineer It's great to see a new thread build on this forum, the 'King' is a great loco too. I for one will look forward to your updates. to Miss Prism, I think that you may be a bit too quick off the block, it looks to me that the rivets haven't been fitted yet. To the RMweb admin, can you do something about the image posting please, clearly it's not only me who has issues with pictures showing 'upside down'. I post to a number of sites and only here do I have this issue? Regards Pete

Inside connecting rod is now fitted, next job will be a lot of tidying up and a fair number of oil pots to be machined. It's all getting pretty tightly packed in there... http://4472flyingscotsman.co.uk/inside-connecting-rod-and-piston-crosshead-fitting/ Pete

Evening chaps, this is the more detailed 'walk around' video that I promised last time around... please forgive the few errors such as calling Wakefield lubricators, 'Westfield'...:) Pete

The new blog entry which covers the first outside piston to be fitted has just been posted, the other one will only take me a short while in the morning and then I'll do the middle which I'll cover in its own entry sometime next week. http://4472flyingscotsman.co.uk/outside-pistons-fitting-process/ Pete

good day all A couple of quick videos to share with you guys...rolling test after fitting the outside rods (tolerances are crazily close in some areas) and a short overview video. I'll do a proper 'walkaround' video describing the various oiling points and fine details soon. Pete

Tonight's, blog entry sees one of the outside connecting rods fitted. Well, still I have two small jobs to do, details in the blog. http://4472flyingscotsman.co.uk/outside-connecting-rods-fitting/ Pete

Good afternoon folks, my apologies for lack of blog updates over the last few weeks. As mentioned my mill decided to throw a wobbly which slowed things down somewhat. Luckily it didn't cost money to fix, just stripping down the spindle, repack with grease and tightening the taper bearing collars. This blog entry covers the completion of the outside connecting rods, well accept some final bits which are detailed in the blog. The updates may be less regular for a short while as I'm going to be giving my classic car some much needed TLC, it won't stop the updates but will mean my time is split for a while. http://4472flyingscotsman.co.uk/outside-connecting-rods-part-2-completion/ Pete

Well no blog entry this week due to the mill throwing a wobbly and thus stopping me in my tracks with the connecting rods, I had hoped to have them finished today. Oh well, I need to strip the mill head down and find what's rattling like stones in a tin can....lol Not to be beaten, I took advantage of this downtime and revisited the pipework on the crossheads. I have added the details in the drop link blog entry. The solitary picture is shown below. Pete

New blog entry, this time the 'Outside Connecting rods' hopefully these will only take two parts. Here's part 1 http://4472flyingscotsman.co.uk/outside-connecting-rods/ Pete NB:.. sorry, the web page still seems to not take my photo's the right side up?

An early blog entry for this week, the drop links are now made and fitted temporarily to their respective outside crossheads. Next will be the outside connecting rods, hopefully, these won't take as long as the crossheads... http://4472flyingscotsman.co.uk/drop-links/ Pete

good day, all.. well, I think that I can finally say that the crossheads are completed. I still have the drop links to make but they are separate parts, I'll make those next. I do have one final operation to do which I detailed in the blog, it's only cross-drilling the little end journals, that will be my first job Monday. I also listed the next stage of the build, when that work is done, (could take a while) I'll have pistons connected with the wheels, another important milestone reached. http://4472flyingscotsman.co.uk/crossheads-part-7-oiling-system/ Pete

The crossheads are very close to being called finished (for now that is, there will be some fine polishing for all parts made to date at the end) As can be seen the oil reservoir has been made and bolted to the slipper. I decided to silver solder the inner bolt heads as the model doesn't need 4 practical bolts to hold the reservoir on, makes life easier. The top side face of the crosshead where it touches the slidebar has also been rounded off as mentioned last time. I have made a 5/32 x 40 oil plug with a small central hole to avoid a vacuum which would stop the oil flowing. The last job to do here other than the 'drop link', is a small copper pipe which comes out of the bottom of the reservoir, is angled approx 45 degrees towards the front (others will be handed) and then snakes back to the centre of the gudgeon pin. I hope to post a blog update covering all of this end of the week, count this as a taster... Pete

After 4 weeks slog the crosshead bodies are more or less complete, I have forgotten to curve the top edge of the sides which I'll take a look at tomorrow. http://4472flyingscotsman.co.uk/crossheads-part-6/ Pete

Crossheads Part 5... there's a lot of work in this one and I still have a long way to go. I was hoping to have finished the crosshead and mounting plates for this entry but the lathe decided to shred its V belt which meant I couldn't turn up the last 'button' required. probably a good thing really as this entry was getting a bit long. Hope you find it of interest. http://4472flyingscotsman.co.uk/crossheads-part-5/ Pete

Crossheads Part 4... I'm now at a stage where I can breathe a little easier, I have finished the machining for the front area (rear will be the last part to do). From this stage on it's all down to hand grinding/filing and polishing, I have made a very small start at the end of this entry. On a footnote, can anyone tell me what a full-size cotter pin measures? preferably that as fitted to an LNER/BR Pacific? thanks http://4472flyingscotsman.co.uk/crossheads-part-4/ Pete

Part 3 of the crosshead construction.. we have a long way to go before these are finished but we do have some progress... http://4472flyingscotsman.co.uk/crossheads-part-3/ Pete

ah... just read up on Turcite, should have done that first...:) I had assumed it was like acetal...no, most certainly not suitable as a bearing surface... reading it's description, it captures grit and destroys bearing surfaces very quickly... that would be very bad on a steam locomotive with all the ash which gets everywhere...:) Pete

Hi Tiger An interesting suggestion which I think your saying to use for the slipper, I see why you suggest turcite with it's self lubricating properties but I doubt that it has enough tensile strength. The slipper although just a sliding part will also be subjected to some hammer blow from the action of the con rod, a plastic isn't likely to last long in such a situation, IMHO, of course. Some use bronze to good effect and again I can see the reasons why, in fact the drawings state 'bronze' although this would need tinning to look right. However I have spoken with some fellow model engineers who have found gauge plate very good with many years of use with no wear if lubricated properly. I guess one could use mild steel with gauge plate slide bars but I prefer to use gauge plate for its strength and stability. I wonder what they use full size? Kind regards Pete

Gauge plate, both the slide bars and the slippers are of the same material.. there will be a constant layer of oil between the two. Pete

Part 2 of the crossheads, these parts may take a few more entries before completed, I'll probably throw in the drop links too. In this entry, we have the slipper oilways, gudgeon-pin holes and piston rod hole. A few more changes from Don's drawings. http://4472flyingscotsman.co.uk/crossheads-part-2/ Pete

Tonight's update (sorry for the delay, I had a break over Xmas) covers part 1 of the crosshead fabrication. In Don's words, he states that the trickiest part on the whole model was probably the steam sander bodies? well tricky maybe but the crossheads are going to take some time to complete and probably as much work as the coupling rods with their fish bellied profile which included the fluting. Anyway, here's part one which covers getting the blanks ready for profiling. http://4472flyingscotsman.co.uk/crossheads-part-1/ Pete

I wonder who this Flying Scotsman model build series which begins in the ME today belongs too...:) Pete

Evening all, a new entry for the blog although I have added this to the 'news' section as it's not actually part of the build but important none the less. This entry covers the building/design of my weighbridge, very simple to do and can be made to fit anyone's loco stand. http://4472flyingscotsman.co.uk/weighbridge-to-measure-individual-axle-wheel-weights/ Pete

Evening all, it's been a few weeks but I have now uploaded the latest blog entry. This time it's the fitting of the slide bars, well two of them, I'll fit the last bar over the weekend. Note to self, I need scale sized fingers... http://4472flyingscotsman.co.uk/slide-bars-2/ Pete NB: I give up with the image... see it in the blog guys... sorry
