We had a busy week on Fen End Pit, the Easter break meant additional assistance was available from my Son so we managed to complete the cutting and fixing of backscenes and the revisions to the layout legs to better support the boards.
Friday evening meant another night out and a chance to work on the Slater's Simplex. It is convenient to have a project which can be 'carried out' away from the workbench. The buffer plates, couplings got stuck on to the ends.
Also the axleboxes and the axlebox guides got stuck on too (Yes I can see there is some set epoxy to remove!)
I also decided to have a go at reprinting some of the parts waiting to go on my Ruston LAT last seen at http://www.rmweb.co.uk/community/index.php?/blog/186/entry-15979-ruston-latlbt-now-made-progress-on-the-lat/
Previously I had printed the gearbox and engine parts on the Ultimaker in Makespace, a traditional FDM printer which uses extruded filament. I thought I'd have a go on my new DLP resin based printer to compare.
You can see on the green filament printed version that there isn't much detail on the top surface and there is a fair amount of 'ridging' visible from the filament layers. I've not treated this part in any way and would usually prime and sand which sorts out the surface texture somewhat but tends to loose even more detail.
Compare this with the resin version from the DLP printer. The curved surfaces are smooth, the flat surfaces flat and the bolt heads on the top came out perfectly.
I also printed a pair of new buffer beams/weights, these again have a much better finish than the FDM version, I've modeled a pocket in the rear of them to take a piece of lead to give the loco some more weight in the right place.
Finally a great day out was had at the 16mm Associations Garden Railway show at Peterborough yesterday. It was good to catch up with some old friends and chat with new ones. I'm particularly looking forward to seeing Campbell's Quarry again (featuring, not one, but two 10RB models) as we are both booked to attend the show in the engine shed at Leighton Buzzard in August.
I made an interesting purchase for Fen End Pit from PDF models, they have just brought out a 3D printed kit for a Bedford 'O' series LWB lorry in 16mm. Scale vehicles in 16mm scale are not easy to come by, you can find things in 1:24 and occasionally 1:22 but not 1:19. The quality of the printed parts looks very good and I'm rather looking forward to putting this together. My wife says I should 'make it go' but I'm not sure that is really possible.
