    But if you bend the stem of the brass etchings through 90º and mount them on the wagon with the stem at the top, you would get a good representation of a sheeting ring. All it would need is a tiny spot of glue at 12 o'clock to represent the real eyebolt...

    Sheeting rings were about 4-6 in diameter and were held in place with an eyebolt whose hole was only slightly bigger than the wire thickness of the rings. They were arranged so that the rings hung down below the eyebolt parallel to the timbers they were fixed to. This was usually the solebar, but on iron framed wagons the curb rail was used.

    Yes, but the original post observed that the inner sides of wagon planks had no chamfer on the top edges, so a scribed line is inappropriate and the edges of the planks are better represented by lines made by a pencil.

    No, the odd-legs are engineer's tools, but it may be possible to replace the point on a draughtsman's compass with a home-made odd-leg end. I suspect this would have to be made of steel. Keeping the drawn line parallel to the edge is a matter of skill and practice. I once made a marking gauge from a length of 1/8" steel rod and an old gear wheel that had a screw fixing. It had a scriber point which was a force fit into a radial hole. Making one with a pencil lead would be slightly more complicated

    Yes, but try and find a pair with a pencil rather than a sharp point.

    So about the same as the £12,000 million a year we pay for useless windmills?

    ...Or just take the floor out.
  8. billbedford
    Not if you use a compass or a miniature marking gauge. Set it to the plank depths and run the point rod around the top of the planks. Actually, I print grooves on the inside of the planks, but at only two-thirds the width of the outer ones. This should be just enough to show when weathering, but not noticalble otherwise. That's the theory anyway.

    The Welsh Welsh had a way of dealing with such incursions, they just set fire to cottages owned by English incomers.

    It's worth remembering that most northern American cities had district heating systems, which made coal deliveries by hopper wagons efficient.

    But what beard game did he play?

    A pair of solenoids in the cylinder housings?

    How many decades? SLR is <3mm/year around Britain.

    If you have rivets on the bottom of your prints these are very good places to land supports on. Better still, always think of your prints as 5-sided objects.

    The curing station I have heats to 60º and the cures for an hour with the heat on. I don't think I've ever seen breakages along layer planes. If the elephant's foot can be controlled then the best orientation is likely to be with a long edge on the bed and the rail gaps in the chairs vertical.
  16. billbedford
    Yup, but that's what njee20 has.

    Curing will polymerise the resin across the layer boundaries. I use 60ºC for 60 minutes for an ABS-type resin. These values were inherited from a similar Fromlabs resin. This video has more information: https://www.youtube.com/watch?v=886X2geCRrA&pp=ygULY25jIGtpdGNoZW4%3D

    Isn't more that the vast majority of Londoners are not affected by the costs of the ULEZ?
  19. billbedford
    Isn't the signal box hidden by the train?
  20. billbedford
    I do those, but you have to buy a whole wagon and take them off yourself.
  21. billbedford
    No, not sunk, but it seems that two of the forward compartments are flooded.

    The Camel had a rotary engine, which made the torque a whole lot more than on later aircraft. Yup

    I found this on YouTube: https://www.youtube.com/watch?v=BEzDh4RwpaM Which seems the most likely explanation I've seen. Who hasn't panicked and ignored the non-intuitive best course of action? O'corse the guy might be wrong.

    Most people think the media is reasonably credible until they write about a subject the reader has some knowledge of, and then they become woefully uninformed.
