Jeff Smith Posted November 18, 2021 Share Posted November 18, 2021 A friend has printed for me a set of parts to build a static model of the title loco. He has no interest in trains and was more interested in seeing if he could actually print it! The files come from https://www.thingiverse.com/thing:3836701 and the model is 1:48 (Proto48) which of course is very odd for a UK outline model. It has been printed in PLA - I'm not sure what adhesive to use as it is impervious to MEK. The flash is very thin and just breaks off. 1 Link to post Share on other sites More sharing options...

amandalee Posted November 19, 2021 Share Posted November 19, 2021 Hi...Looks like a great and thought out kit. I prefer the gel type super glue as it has a little more forgiving time. https://www.gluesaustralia.com.au/tarzans-grip-shockproof-super-glue-high-temperatur In your neck of the woods something similar that dosent bond instantly would be available. regards.....

Poor Old Bruce Posted November 19, 2021 Share Posted November 19, 2021 Looks interesting. You must let us know how you get on. Link to post Share on other sites More sharing options...
KeithHC Posted November 19, 2021 Share Posted November 19, 2021 I see the designer also does a 57xx pannier as well. Keith Link to post Share on other sites More sharing options...
Jeff Smith Posted November 25, 2021 Author Share Posted November 25, 2021 Initial searches for a solvent for PLA suggested Ethyl Acetate (mainly used by butterfly collectors) but it does not even touch it! So super glue it is, gel and brushed, seems to work well with good surface prep to give a key. Emory boards and fibreglass brush. Link to post Share on other sites More sharing options...
Jeff Smith Posted November 28, 2021 Author Share Posted November 28, 2021 (edited) So, getting to grips with the model now. My previous 3D model from Shapeways apparently used a gel to support unsupported elements during printing, this type of printing uses a printed open lattice which has to be cut or pulled away. eg the buffers which I initially thought were solid actually had tubes printed under the buffer heads which fell away once cut revealing the detail underneath. As may have been evident in the earlier pictures, the axle holes were all different sizes and in fact were too narrow so squares of styrene were glued on and drilled 1/8" to suit the 1/8' styrene tube I am using for axles - all the wheels had blind 1/8" axle holes.

Jeff Smith Posted December 2, 2021 Author Share Posted December 2, 2021 More progress being made. The cab front/backhead needed some adjustment to ensure that the wrap around tank sides and roof fitted correctly. Next job is to fabricate some rear driver splashers to go on the cab floor - these weren't included. There are some deficiencies but I am very impressed with the way the kit has been designed. PLA is actually quite nice material to work with - very similar to styrene. 5 Link to post Share on other sites More sharing options...
Jeff Smith Posted December 4, 2021 Author Share Posted December 4, 2021 This is going to be a display model so the scale is not of great importance, it'll stand on a piece of Peco 7mm. BH track. Just curious if anyone has the overall dimensions of No 80? The model is 206mm over the buffer beams and 55.5mm footplate width. Link to post Share on other sites More sharing options...
RMweb Premium Nile Posted December 4, 2021 RMweb Premium Share Posted December 4, 2021 Length over buffer beams = 35' 7.5" Width of buffer beam = 8' 6" Width of cab = 8' 0" Link to post Share on other sites More sharing options...
Jeff Smith Posted December 4, 2021 Author Share Posted December 4, 2021 Nile, are you sure about the length? Whilst I have no idea of the accuracy of the kit (stated as 1:48) your measurements would scale as width 1:46.3 and length as 1:52.7 scales......assuming my math and measuring are ok!

Jeff Smith Posted December 4, 2021 Author Share Posted December 4, 2021 Further study of the kit suggests that it is considerably under-length. The smokebox is visibly much too short..... Link to post Share on other sites More sharing options...
RMweb Premium Nile Posted December 5, 2021 RMweb Premium Share Posted December 5, 2021 It's in original as built condition. The longer smokebox came later with superheating. Looking at another drawing: Length over buffer beams - 35' 2" Length over buffers - 39' 0" Width of footplate - 9' 0" (that seems a bit wide to me) Link to post Share on other sites More sharing options...
Jeff Smith Posted December 6, 2021 Author Share Posted December 6, 2021 That explains the smokebox difference. However over the buffers it's still 3/4" short but I'm making this for the friend who printed it and has no knowledge of railways....it'll look pretty when finished!

Jeff Smith Posted January 9, 2022 Author Share Posted January 9, 2022 Well, as stated before, it looks pretty.... Had to add main driver splashers in the cab. The livery is simplified and just shows 80 rather than Thundersley and the lining is just the raised line picked out in black. I was tempted to build it using only the parts supplied - the smokebox handrail was printed and actually went on better than expected but I had to add the clack-valve pipes, the buffer beam hoses, lamp irons and coal.... As an approximation for a non-rail person quite nice I think... 5 1 Link to post Share on other sites More sharing options...
