I'll start with the lesson in observation. When planning a model of a wagon, check what axleboxes it had in the period you'll be modelling it in, don't rely on more recent photos!
I've been turning my attention to the Nitric Acid tanks again, as a little bit of a break from the 37 bogies (more of that in another post to follow shortly) so dug all of the research material out the other night. In a previous post, I'd been drawing up the SKF axleboxes, as that's what I thought I required but closer inspection of some older photos of the tanks, in UKF colours show them with Timken axleboxes (all except the Pedestal suspension fitted 949 and 950).
Having realised my error, I've set about drawing up the Timken variant of axlebox. It's going to be quite a useful thing to do anyway, as it was fitted to such a wide range of air braked wagons, including the VAA and VBA vans, which I plan to turn my attention to at some point. So here is the current work in progress, on the floor this time rather than floating in mid air:
It's shown in parabolic spring configuration, for use on the vans it won't need the circular spacer on the top, there's a few little tweaks to do, but it's more-or-less there. The text on the front projects further than it should, the same as the last one, due to the minimum size requirements for the 3D printing process. I'll sand the print to reduce the size of that before using it as a master.
The SKF type wasn't a complete waste of time though, I can still make use of it on another type of wagon in the future.
