    Spring is here and things are warming up, so as Mr Dundee keeps alluding to I have a monster print list to get through as well some assembly work, to start off I decided to print off an R1 coke wagon:

    IMG_1190.jpg IMG_1191.jpg

    The wagon body, running etc all printed very nicely as above, but I tried to go for fidelity with the brake levers and pin rack frankly they are just to thin and fragile so they need beefing up and reprinting but that's a minor job.

    Sat awaiting assembly are a C2 open, a C9 open and now an R1. Sadly my work bench aka the dining room table is occupied by a 3000 piece jigsaw that swmbo is doing and has been for at least 6 weeks with little sign of completion, so assembly will have to wait.

    Still to print but in no particular order:

    C2 open (late version with alternate side and end strapping)
    G1 van
    K1 cattle
    V1/1 Brake (though I am still not happy with the interior so may well just go for a closed version)
    V1/2 Brake (in the same state as the V1/1)
    V1/2 Brake with alternate outside frames and roof.
    D1-D2 Bolster wagons
    D5 Twin Bolster wagon

    The following need me to get the second-hand Mono X I bought 6 weeks ago sorted, sadly I am completely out of ideas what's wrong with it.

    P6 17-1/2 ton coal hopper
    A1 Ag Imp
    Dgm 60 luggage van
    D10 Double Bolster
    B3 Plate wagon (and its conversion to a trestle waogon)

    Then finally in a state of stasis and not completed to my satisfaction yet.

    Early Brake Van - needs tidying up and there's a few bits to do.
    Dgm 53 Brake Third
    Dgm 64 First Third both these just need tidying up.
    Snow Ploughs No 7 and 12 - I'm still unhappy with the Plough element of both these despite having nibbled away at both over the last few weeks.

    Phew - quite a list, let hope for a long warm summer

    Rob,

    Just tinkering about and trying to keep the brain active while I adjust to retirement - not finding it easy but I know that's a common thing.
    Just for the hell of it take your pick on the next two to be print,

    An impressive print, now we've turned the heating off, I will have to wait for Scotland to warm up a bit (maybe next time the heating goes back on).

    For the jigsaw, use a silicon mat to rest the puzzle on , add some resin and voila a permanent picture - hopefully finished before the resin cures in daylight. OK I'll got stand in the corner.

    For the brake gear, try lifting the model higher from the build plate (7 to 9 mm), use a heavy support to nail the lowest point, the add light supports with minimal penetration (0.1 to 0.2mm) to help keep the model in position. Once printed break away the light supports before the model is cured, then with luck when you cut the heavy support (at the base first) the model should stay in on piece.

    Thanks for the compliment Paul - it's a pretty little wagon, if in NER terms a bit obscure.

    I will try your suggestions regarding thin prints, as a matter of course I remove all supports with a tiny sharp pair of scissors after washing and long before curing any bodies. Until now I have printed brake levers/pin racks 1mm thick, this time the minimum thickness got down to .3mm which is just to small so when I reprint them I am going to spilt the difference and use a minimum thickness of .7mm.

    Cool,

    In that case, I suggest the K1 cattle wagon and the D1 D2 Bolster wagons as the next victims.

    I’ve had my first success print with the settings you sent me the other day (along with some changes to the lift and retract speeds I’d been using from someone else!

    Wow! The supports just fall away in warm water! Never known that.. I’ve had to cut away with blades previously!
    Thanks

    I think Paul passed them on to me so you should really thank him.

    How a beautiful morning slides into misery and cock-ups

    Bright and early this morning I fired up the printer and set my first K1 print running. I didn't have great expectations as it had never been printed before so this was almost a 'test print'. Glancing at the expected print time it looked a bit quick but I really didn't think much about it. Well by 1:30, the print was finished so out came my K1 and had transmogrified into another R1 Coke wagon, anyone want an R1 coke wagon? Yes I had obviously initiated the wrong print job. After a quick clean up of the build plate and more resin added to the tank I fired up the K1 print, and yes the print time was almost an hour longer than the morning print so I was sure it was the right one.

    Just after 7: this evening the K1 was finally fished out and washed and scrubbed up, hmmmm not good, a) I had missed supporting one of the cross member so instead of a nice horizontal member I have a bow shaped cross member and b) the strapping and hinges of the upper doors are hanging off, instead of combining them with the doors I had combine them with an external strap. &^**(&. The strapping might be salvageable using my new UV activated glue that works on resin but after all it was a 'test print'. Correction requires a complete rebuild of the side. Such is life, as many downs as ups.

    In the cold light of morning

    Last night I spent some time checking the 'test print' and in addition to the hinge strapping problem:

    IMG_1192.jpg

    I also realised I hadn't modelled the planking cuts on the inside of the body sides. As I am still waking up at stupid o clock over a year after retirement I set to and completely rebuilt the side of the cattle wagon correcting both problems. When I first started using fusion 360 I religiously noted down each step I took during a build, a habit I have now stopped, so it took me a couple of goes to get the sequence correct, but now happy with the changes, it needs putting into chitu for supports and then a second print later today when things warm up a bit more.

    After 50 years of getting up at 'silly-o-clock', 3 shifts, and eating your dinner in the middle of the night, it took me a while to get out of the early awake habit, but after 10 years of retirement, I reckon I'm over it now, but I know where you're coming from Mossy. Your brain, your stomach and your bowels all get 'out of sync' when you keep changing shifts, and when I changed jobs having taken voluntary redundancy at 56, I vowed not to do shift work again, but my final job was anything but 'days regular'. At least retirement brings a degree of stability!:giggle:

    Hi Mossy

    You may want to add some light supports between the top of the doors (and side panels) and the underside of the top beams. Not much penetration, but just enough to help keep everthing straight and in the correct location as the layers print - cross bracing between supports will also help keep the whole lot inshape.

    Otherwise its looking good.

    Been there, got the T shirt. I did it for 25 years and have been retired for 10 years and still have sleep problems.

    Keith,

    I live in Leeds but for 20+ years worked on the outskirts of Warrington. I was lucky in that the company allowed me to start and finish early to avoid the queues on the worlds largest carpark (also known as the M62). I used to get up at 4:30, leave home about 5:15 and hit the office for a 6:30 start. The two hours before anyone else arrived were the most productive of the day. These days it's about 5 when I get up so I can get 3 hours fiddling about before she who must be gets a delvery of tea and another hours before she emerges from bed.

    Paul,

    I have supported the exposed horizontals at the top with light jobbies and also in the gap between the lower 2 planks and the 3 above. I also placed suppports under each of the diagonal cross members. The chitu file looks a spaghetti job.

    On the inside there won't be any grooves as the top and bottom edges of the planks are square. On the out side the bottom edge of the plank is square, to act as a drip, and the top edge is chamfered, to take away the water. This is to try and keep the joints dryer, to help stop rotting.

    Peter,

    I didn't appreciate that, a bit later for the fleet of wagons already done (it would be a right b..... to fix then now) but I will incorporate that on any new models.
    Effectively you describing a v notch with one edge at right angles to the planking as in:

    Mind you at a depth of .2mm it would barely be visible, even so thank you.
