    Thanks Rob, I'll see if he will send it to Aus as I could only find new ones locally at about $100 [​IMG] when I looked the other day - I have a rather large plate of glass on my workbench which I do use reasonably frequently - if anything it may be a little too large but it does the job. As it happens I managed to fudge it with a square - I measured off where the handrails should be once I'd set the backhead and cab.

    Progress on the body has been steady this weekend with the major components now soldered up - its starting to look like a locomotive now! The only real area i had to do some fettling was the cab front and splashers to fit the boiler and backhead in. Any other issues were more of my making - one of the joys of that solid boiler is that it hold heat for quite a while and things will move if the solder hasnt solidified !

    anyways here she is. There's quite a bit of clean-up still to be done so excuse the mess...

    Right hand side - as with the N9 the multi layered smoke box claimed another drill bit- the enlarged hole will be used to epoxy the handrail knob in place - with steel handrails I think it'll be strong enough The firebox side extensions fitted well, but oddly enough, I had little difficulty getting the left hand side down, and the right fought me every inch of the way.. oh well... its in. I still need to put a little bit of filler in the seam and smooth them back but it looks like I managed it ok..
    [​IMG]
    the cab, Still need to install the floor, I'm not quite sure how it is meant to fit - its U shaped so i dont know if its meant to point backwards or towards the firebox. its also a tad too wide to fit between the splashers so I'm tempted to make a new one!

    I'm also going to see if I can make a believable cab from the kit parts - it was easy enough to round off the back head a little - to put in a seperate back head would have meant shortening the boiler by 4-5mm and probably much more fettling to get it to fit so this will be an interesting exercise

    finally with chimney, dome and cab roof sitting in position , we have something resembling an engine!.

    I might try and get the chassis up and running next - although with press fit wheels this will be fun.. I have yet to decide how best to approach rear of the cylender block and I need to put in a front to the fire box - the kit came with two very small plates to put in leaving a very larger gap , presumably so the drive can go to the middle axle. I was thinking of inverting the motor and driving it from the rear axle so if that works I may be able to fill the gap quite substantially - and put a more extensive impression of the valve gear and con rods in !

    Mmm. I can see me cutting a section out for the motor and then milling a recess in each side to accommodate those side plates.

    From what you describe I wonder if it's designed to fit forward to accommodate an open framed motor in the dim and distant past?

    Now that's novel, it's a bit reminiscent of the famous ACE etched backhead only much much neater. I am sure that it will dress up nicely although I would be tempted to add all the fittings before fitting it permanently to the cab/smokebox saddle - making them removable of course.

    Its been a while since I last had anything really to update. Progress on the J25 has stalled a little - I successfully milled out the frames to take a set of Slaters Horn blocks, fitted them, then sort of stopped... partly because its getting quite warm on my room on these summer days and partly because I wasn't too sure how best to fill in the gap between the frames. Anyways I'm thinking I may put in come cranks and make at least the con rods move - That will mean cutting an axle but its worth a try...

    to do so also means I needed a few supplies which wont be here until after new year...

    I did, however, sell a couple of Westdale Pullman carriage kits which has meant I could install sound into the Austin 7 reusing the now repaired ESU decoder that was originally in the WD reblown with Locomans Heavy LMS goods ( ie 4F) file .

    so here she is, making noises...



    I also did a video showing her motion moving a little closer ...



    I've also ordered a Zimo MS450 from Bucckanbool for the A5... That should be here in January so things might be getting a little noisy around here.

    Finally, a few months ago I had bought a Canon 1833 w 40:1 gearbox from Footplate.. Its now in the Johnson 1F, replacing the original open frame (Pittman?) motor, and she runs.... mostly.

    I am still having intermittent shorting issues, which may well be related to having only one set of wheels insulated so I 'm thinking I may have to cut the spokes on the live side and add pickups there. It also has a habit of derailing on certain points.. which is a nuisance, Not really sure why, maybe there isnt quite enough sideplay on the drivers , but I'm determined to get too the bottom of it - ah well, the joys....

    Anyways everyone, I hope 2025 brings you new model making adventures, Happy new year !

    Hi Stan,

    To make the conrods or crossheads move you don't need to cut the axle.

    If you attach them to eccentrics, which are in turn attached to a sleeve which can be pinned or grub screwed to the axle it saves you cutting it. You won't get the full range of movement that you would from proper cranks but you will certainly get some visible movement

    Hi Rob

    I had considered eccentrics- its how my brother schemed up the working motion in the 7F but I'm thinking cranks will be easier to make- I also think the big end might be simpler as well.

    I also need to fit a representation of valvegear between them too, but I'm not planning to make that work. Anyways, still a little way off so may yet change my mind!

    I agree, building for myself, I would use cranks too (assuming that the loco in question had inside cylinders and not just valves) but having done it before, cutting the axle holds few fears for me. I was just offering an alternative for those who really don't want to go there with fitting cranks and then cutting the axle.

    I suppose it depends on how visible the waggly bits are under the boiler as to what you can get away with.

    Its definitely pretty open in there!

    so cranks are probably the best solution. I've still got a couple of other kits with the same (early ) press fit wheels so have extra axles if I make a mess of it - My only real concern ( newbie over confidence ?) is soldering the assembly together - will high temp soft solder be enough, or should I look to silver solder?

    I have just used soft solder but if you have concerns you can always drill and pin the cranks after soldering before you cut the axle. For soldering I would try to get hold of some Bakers Fluid to use as flux (assuming that they sell it over there in Oz). I had it recommended by a pro builder as it's much better for soldering steel.

    Depending on what material you use for the cranks another thing worth noting is that once cut, the axles/cranks are quite vulnerable to being bent out of line through careless handling. This is especially the case with the cast brass or nickel cranks sold through the model trade which are easily bent. If you have bought them in it's also worth checking that the holes which have been drilled for the axle are properly aligned with the cranks. I have a crank axle floating around here, destined for the Joy valve gear in my F8 where they weren't and I didn't notice until I had soldered up and cut the axle that one of the cranks was leaning to one side...

    I would suggest for press fit wheels, that when pressing home the wheels, you make a up a couple of wedges and insert them in between the crank webs where you have cut the axle. This should help prevent them being being bent out of alignment.

    Another option would be to fit hornblocks and make them removable (even if it's only those on the crank axle) so that you can fit the wheels off the loco giving you more chance of supporting the axle/cranks etc. while pressing them home without trying to juggle everything while it's sat in the frames with limited room.

    Hi Rob
    Thanks for the tip about Bakers - I have a bottle that I've been carting around for decades, but its still available through our hardware chains. I've bought some 1/16 brass strip to make the cranks out of, the plan is to make the cranks out of that, and use 1/18 to form the big end and straps around a 1/8 crank pin - hopefully that will be solid enough

    fortunately I managed to mill slots for slaters hornbocks in the frame, was a little harder than that of the N9 as the frames had been assembled and soldered up at the same time as the tender, but it all seems square. Being an older kit the wheels (slaters or maybe even Maygib?) are press fit, so the crank axle will have to be the one I set my quartering off but I'll deal with that when it happens - I know I will need to get some Loctite as I recently did a test fit, and one wheel wouldn't retain its quartering/gauge.

    I've also created a minor issue on the tender : I found the chassis was rocking on the body slightly, and in trying to correct that, have created some serious drag on the outer axles , so I need to drop the wheels, and correct that too.. I finally ordered a 3/16 reamer last week so can hopefully open up the bearings a fraction when I reset them - The leading two have also worked themselves loose, so I may add retaining/springing wires to add some degree of flexiblity to them too - all good fun

    Hi Stan,

    To save me looking back through several pages of posts, can you tell me which axle you fitted the gearbox to on the N8/9 please?

    Hi Rob,

    Drive is off the centre , with the motor (RG7) vertical between that and the last axle

    speaking of motors, I picked up a mashima 1833 with a 2 stage 33:1 gearbox the other week - its a fraction too wide to fit between the hornblocks on the J25, but I'm thinking it might work well for the B16, hanging off the last (fixed) axle - I think I'll use 3 point compensation as designed on her

    and last week bought the Gladiator Q6 kit that steamline has been tormenting me with for a few months! It'll be interesting to compare how the design of it differs from the B16 and Q5 - I found a few notes about it on the GoG forums so there's a few references about building it to refer to

    looks like I'll be busy building some NER big engines for a while (just as well I cant really come up with any reason for Q7 to be south of Darlington)

    Thanks Stan,

    I asked because I have fitted horn guides to my N10 with a fixed rear axle with a view to having the gearbox fitted to the rear axle. But I am struggling to make any of the gearboxes that I have fit on the rear axle. It looks like it will be plan B, the middle axle...

    Funnily enough over the last couple of days I have had my Haywood railway Q6 kit out of the box checking things after a discussion about Haywood kits with a fellow LNER modeller who has the Haywood J27. I had previously noted (but not thought too much about it) the fact that it has a resin coal load included. I bought the kit 2nd hand so I vaguely thought it was an addition by the previous owner. It turns out that there is no provision for the sloping coal space in the kit. You are just expected to fill the tender with this lump of 'coal'. It's actually an advantage to the guy whom I was discussing it, as he wants to fit radio control gear and this design makes it quite easy.

    Having had to deal with more than one ill fitting tender coal space, I can sort of see why it's designed that way. As I like the added detail, I will be using one of my other NER tenders as a template to cut out my own sloping coal space. I am pretty sure that you won't have that issue with the Gladiator Q6. All part of the 'fun'

    Fortunately with the tanks and sandboxes running the drive off the centre axle isnt too obvious on the N9, and I daresay I probably tried running it off the rear axle and gave up - I'm certainly going to run the drive from the rear on the J25 with the motor mounted vertically but I'm still having a period of "writers block" on it at present. As it tuns out I may have picked up a J39 at a reasonable price, so hopefully find my mojo reworking that into a starbeck machine...

    Your comments about the lack of coal space on the Haywood kits is interesting - There's a D20 out there at present that suffers the same issue, tempting as its a very good price. The tender would need a complete internal rebuild, but apart from being incorrectly numbered and needing some additional detail the locomotive itself looks like a good basis for something - the hardest thing would be finding a Northallerton or Starbeck D20 still running with its original smokebox door in 1950 - a few did manage to keep them until withdrawal so not an impossible task...

    now having bought the Q6 kit, a J39 and a couple of Gresley coaches it may be a bit of an ask in the short term ..... :scratchchin:Anyone in the market for a DJH Clan kit?
