    Mike,

     

    Excellent and inspiring work.  I have come to the same conclusions about 3d printing and locos.  My current musings centre on producing a 3541 and Hawthorn 2-4-0t.  I'm thinking about 3d printing the tanks, boiler,smoke box etc, probably the bunker (or having it as a former around which brass sheet is bent.  My plan - based on drawing up a D0 parallel boiler and cab for a SG Dean Single - is to print the cab front, but have brass side (to get them as thin as possible.  As to the footplate, I think the valences, as you have done, must be brass, but I'm thinking about a 3d printed sub frame over which a brass footplate is placed (splasher clearances being a problem area), and which will provide a means of locating the valances very precisely too.

     

    Regards

    Has anyone found drawings of the CMR iron bodied China clay tippler wagons? Or close up photos?

    Very nice!

     

    You mentioned that you had several one-plankers on the go. Is this the one in the drawing in Atkins et al?

    They are based on the Atkins et all drawing - I've done 15'6", 16' and 18' overall ones.  I suppose I should do an 18'6" one to complete the set.  Now I just need info from the wagon registers about running numbers and which ones were fitted with oil axleboxes and when...

    Chaps,

     

    Here are a couple of my first attempts.

     

    At the top we have a GWR S7 fish wagon with bars for the sides (I intend to use 0.5mm brass inserted through holes in the print - it is currently printing so I'll find out tomorrow if it worked)...I'm working on the Broad Gauge 6w predecessor of the S7 at the moment but need to redo the solebar as the axleguards/w-irons (only they aren't w shaped) are wrong.  I also need to draw up internal bearing units on a 4w truck so as to make a proper chassis that will hopefully enable it to go round corners!  

     

    Beneath it is one of the 1 planks.  They have already been printed but without solebars and went banana shaped while curing.  I am hoping the solebars will help limit distortion when they are printed and cured (hopefully tomorrow).

    Plan :o   ... I shall use the drawing from 'Broadsheet' No.52 but I shall need to find a way of making the planking more obvious, I think.

    I’m experimenting (at work so there is a hiatus for half term) on doing the planks by having a 0.25mm rectangle for the gap between planks that I can intrude into the side perhaps 0.25mm.  Still at the drawing stage - one side of the unique BG convertible 4 plank prototype with its nine standard dimensions and wheel base - and the end to do.  Then more trawling of fusion tutorials to see if there is an easy way to duplicate completed faces onto new sides/ends.  I’ll let you know how it goes! ....

    Very nice. Any plans to do the version with the guards caboose? And a broad gauge version? I think that the ends of the floor planks though be covered with a continuous curb rail rather than showing the ends of the floor planks.
