    That looks superb.

    From the photos that I have, I think it's more of a hinged T bar hanging from the door that fits into a slot in the rectangle on the body. Sadly they are only quite small so no chance of enlarging them to clarify the details.

    The drawing appears to show a simple square with a circle in the middle, but who knows. little t sections might just beyond the pale.

    Well I think another project to be parked up. For a laugh I am going to play with the C1 next. Draw a few planks, copy them and position correctly. Easy peasy in theory but who knows.

    Very impressive Mossy, i'm sure the final print will be just as impressive.

    I would just draw an inverted T (with the T bar at the bottom) half round and have the plain narrow end beginning on the rectangular plate and then overlapping onto the body. If you want to include them as a print as opposed to adding them later I can't see any other way. For the T slot on the body you just need a T shaped recess in the plate to give an impression of that's where it fits when the doors are opened.

    Is this what you meant Rob?
    The results of half an hours fiddling before my weekly ritual humiliation aka ballroom dance lesson.
    I don't know if they will show up much or if they will ever see the light of day, but I will know they are there.

    That's exactly what I had in mind although I was thinking more of having them half relief so that they weren't so vulnerable to being snapped off.

    If I were ever to think of printing it I would extrude behind the inverted T piece back to the mounting plate and or van body rather than half relief, either way they are so tiny it wouldn't affect the overall model. I fiddled about with them this morning and decided to extend the vertical bar from .9mm to 1.5mm, it looks much better now and also recessed the receiving plate so it logically fits.

    Looking good, but for printing, I wouldn’t worry about the T cut away on the inside.. great you have made sure it worked in theory, but it’s not going to really be working/used in 7mm so I’d just show the outline.

    going back to the chain, yes from what we have now on wagons the bolt and loop would probably be correct. I would see if you can draw a chain up full size else where then scale it down..

    once it’s on your model, sink it in to the body by a few fractions of a MM so it’s part of the model and grips it rather than standing loose and at risk of being knocked off.

    still in awe what you guys are doing on Fusion.. I really must have a go.. sadly the one item I did turned out too big!

    by the way, save your models.. there may be someone willing to print them for you at a later time. Just cos it’s too big for your platform.

    Hi Andy,

    Yes they are saved but basically as a model of half a side, end, headstock and solebar, one of these days I might invest in a Mono X or some other bigger build plate 3d printer and then have to complete them.

    As for the chain, first trick is to get a simple oval link circular in section. I have had a couple of goes but given and been driven to drink - that at least is pleasurable as opposed to banging your head on a brick wall.

    I’m not sure an Oval should be that difficult? Copy, paste and reorientate?

    :cheers: Enjoy the drink and have another crack. Even start with a ring and elongate? Or.. a half circle, add in a small straight of the same dimension and then copy the half circle and put on other end.. and a loop is formed. copy, rotate 90 and move down so it sits inside the other end.. and repeat???

    To get an oval link circular in section I would use the sweep command - draw your circle on a sketch on one plane then draw and oval adjacent to it on a sketch on a plane in the opposite plane i.e. one flat, one vertical.

    Select your circle, click on sweep instead of extrude and then select the oval as the path to sweep to.

    Thanks for the suggestions gents. On a highly motivated day I will give it a go, mind you they are going to be tiny loops, but certainly worth a go.

    Yet another question sorry. I have been playing with a wagon with sloping sides. Side 1 nicely drann, need a couple of rethinks but I learned a lot. Now the bug bear.

    When I come to mirror the side I get this:

    Left is the drawn Side, right is the mirror side, which is obviously wrong. Has anyone got a neat simple solution or do I have to redraw it?

    Thanks

    Hi Mossy

    sorry bit late doing some catch up.

    Re the links, were they eliptical or oval. If oval, i'd create a torus (donut the us mere plebs), slice it in half and delete one half. Extrude the two ends half the length of the straight side. then mirror and join to form the oval. Same method will work in 123D and fusion 360.

    For the wagon side, press M (move command), select the side and adjust the angle to give the correct result.

    As always obvious when pointed out, thanks Paul.

    Haven't gone near links yet too much emotional trauma last time.

    Paul beat me to it.
    I had the same issue a while ago and it took a few moments before it twigged that it had mirrored it correctly but I needed to adjust the angle to get it to look right.

    Well another body sorted, just the floor and 10' 6" brake gear to do.
    In interesting experience, sketching on angled planes with angled canvases while trying to estimate the extra height required to compensate for the angle. This ones definitely going to be printed if/when I can start printing again, it's far to cold in our attic just now and there's a backlog of other stuff to print.

    Will the sides not fit diagonally on the build plate ?
    Maybe make the ends with the slot for the sides to fit into, and print he floor / frames as one piece printed on its edge also to fit on the build plate.
