Following the slight issue encountered with the width of the original 3d printed MFA wagon body (see previous blog entry) I have revised the CAD and received another body from shapeways based on the latest 3d model / CAD design. Having undertaken a test fit to a HEA chassis it appears that the previous width issues have been resolved:

My fleet of MFA conversions is now looking healthy with 7 conversions undertaken to date, all of which have been painted in EWS livery with graffiti on a couple based on prototype photos. All that is needed now is to replace the plastic wheels and they are complete. My spoil wagon fleet now numbers 10 wagons (7 MFA and 3 MTA) as shown below, the high end MTAs (yellow and black wagons) are scratchbuilt from plasticard on Bachmann POA underframes.

Thanks to a kind offer from another RMweb member I now have a number of AME MEA bodies (swapped for the HEA bodies) which will be used to convert the remaining HEA chasis to MEAs. In order to fill the resulting gap in the spoil wagon fleet I will be 3d printing a late build "coalfish" body and using this to convert some Hornby HAA MGR hoppers into MAAs.
