Ron Heggs Posted December 15, 2013 Author Share Posted December 15, 2013 Ron, Your latest diode diagram has 'UF' lighting #10, instead of 'US'. Stu Hi, Stu I've done it again DF and DS switches should be 'swapped', as well UF and US switches Thanks Ron Link to post Share on other sites More sharing options...
Ron Heggs Posted December 16, 2013 Author Share Posted December 16, 2013 Have been busy switching between tasks today - The 26 strands have now been threaded through the display faceplate and epoxied in place - Remember this is only a test assembly to prove the viability of building a Theatre Display in 4mm scale The strands will be trimmed back close to the faceplate when the epoxy has hardened Next job is to identify each strand location on the faceplate and tag it with the relevant LED ID The strands can then be epoxied over the relevant LEDs Link to post Share on other sites More sharing options...
Pete Harvey Posted December 16, 2013 Share Posted December 16, 2013 Ron How are you going to mount the fibers on the model as the grouped fibers looks like quite a thick bundle? Pete Link to post Share on other sites More sharing options...
Brass0four Posted December 16, 2013 Share Posted December 16, 2013 Spinoffs: I'll never do work like yours in a million years. I don't understand eletrickery, and don't have the manual dexterity and multiple skills, but I've learned a very useful amount regarding complex structures in plastic - items I would have reserved for brass and burnt fingers - and with this particular passage, how straight forward decorative building-lights/shop-displays could be. Of all the threads I follow, yours is the most educational by far. So thanks for that. :-) Tony. Link to post Share on other sites More sharing options...
Ron Heggs Posted December 16, 2013 Author Share Posted December 16, 2013 Ron How are you going to mount the fibers on the model as the grouped fibers looks like quite a thick bundle? Pete Hi, Pete The fibre bunch is just under 3mm diameter or 1mm x 5mm. The black sheath is heat shrink tubing being used temporarily keep the fibres under control They will be divided into smaller bunches and hidden within the gantry truss members and under the access walkway. That's the intention Ron 2 Link to post Share on other sites More sharing options...

Michael Woolford Posted December 16, 2013 Share Posted December 16, 2013 (edited) Ron, Once my own layout starts to make progress I will eventually install a signal gantry just before the station throat; it will be 2 aspect with a shunt signal and will include a working theatre indicator. It is very much based on the one installed by the LMS at Lime Street Station. Perhaps it may be of use to try and find out how the one on the Lime Street model was made as I'm sure it would probably be of use to you if you do have problems making your own model work the way you want. Although judging by your other work I'm sure you'll manage just fine! If you don't feel it is necessary to look in to then no doubt I will when I get round to making my own.

Michael Woolford Posted December 16, 2013 Share Posted December 16, 2013 I don't think Steve built the gantry. He built all of the semaphore signals but I think John Holden (the owner of the layout) built the gantry and his friend Geoff Peters did the clever stuff with the electronics to make it work.

Ron Heggs Posted December 17, 2013 Author Share Posted December 17, 2013 The displays on Lime Street are up to three times wider than the prototype, and similar non-scale displays could not be accommodated along with all the other signals on the gantries on Manchester Central Ron Link to post Share on other sites More sharing options...
Ron Heggs Posted December 17, 2013 Author Share Posted December 17, 2013 Trying out my new Silhouette Cameo cutting machine. Produced the laminations in 10 thou styrene for the North Face of the GNR Deansgate Bridge - Bottom three are the lower under parapet section The upper five are the above rail parapet section Cut in two halves - Overall length 470mm They will backed on to 40 thou styrene 1 Link to post Share on other sites More sharing options...
Phil Howe Posted December 17, 2013 Share Posted December 17, 2013 Now that is just unfair, Ron! You've had your Cameo for exactly five minutes and you're producing delicate tracery the like of which has never been seen! Have you tried exposing those fine threads of styrene to any solvent yet? Cheers Phil 2 Link to post Share on other sites More sharing options...

Cheers Phil Hi, Phil Not bad for 10 minutes 'work' ? The drawings were already prepared back in Dec 2007, ready for producing etches. The cost of which would have almost paid for the machine Fixing waiting for daylight Easier than working under a lamp Will post results tomorrow Cheers Ron 1 Link to post Share on other sites More sharing options...
Ron Heggs Posted December 18, 2013 Author Share Posted December 18, 2013 (edited) The bridge lamination process using butanone/mek - Bottom two laminations on a 40thou backing Third lamination added Top two laminations Top 3 laminations Top 4 laminations - the trefoil decoration on the lower section is just visible - couldn't cut that by hand Top 5 laminations Full view The face now needs microstrip additions and rosette decorations to complete The rear railside face needs flanges and plating detail adding - South side will be made in the same way Edited December 18, 2013 by Ron Heggs 9 Link to post Share on other sites More sharing options...
Brass0four Posted December 18, 2013 Share Posted December 18, 2013 (edited) Imagine making that without the new kit! Most us would be drilling holes to form a basis for the wave/drip (whatever the devil it's called) profile:- filing to a point then blunting the point till it looks OK from regular viewing distance - hopelessly inaccurate and massively time consuming... I've been checking up on these machines and am astonished they are so reasonably priced - not that I'd ever justify one - panelled coaches, complex architecture, etc.,. etc.... I'm not a young man and hardly a day goes by without some technical mind-blower in the PC+ world. But this machine... Sheeeeeeeeeesh! Tony.

RMweb Premium Siberian Snooper Posted December 18, 2013 RMweb Premium Share Posted December 18, 2013 Hi Ron That machine cutting of the plasticard is stunning and as you say a bit cheaper in the long term than etching.

artizen Posted December 18, 2013 Share Posted December 18, 2013 Where's the button called "Prays to the God of Plastic"? That is simply stunning and opens up a whole new world of complex modelling combining laser, circut and CNC that was only a dream about five years ago.

RMweb Gold Alister_G Posted December 18, 2013 RMweb Gold Share Posted December 18, 2013 Ron, you were already the master of plasticard modelling, but that bridge is just exquisite. Would it be fair to say that you can now incorporate detail that previously you couldn't due to the limitations of cutting by hand? Amazing stuff! Al.

Hi, Al You are quite correct in your comment Some details which would be impossible or difficult to produce by hand cutting can be produced relatively easily by this method Repetitive/multiple copies of the same item can be produced with ease retaining the accuracy across all copies Ron 2 Link to post Share on other sites More sharing options...
