Enigma (Liverpool Lion)

[Jon Nazareth]

I wasn't too sure about fitting a fall plate as, if permanent, would make coupling rather difficult. So, I sat down to make some tiny butt hinges only to give up on that idea, the pieces being too small to hold. I did think that I'd need to do something about a plate or the bishop may fall down the gap when attempting to shovel coal! Then, I thought about the hinges that the LBSCR used on their wagons where all you see is a sort of staple. The idea here was that the fall plate would be held in place by two long staples and removed when the engine and tender were coupled. As it turned out, after making it, the fall plate actually works and hinges quite nicely.

I took delivery today of the springs for the tender which were 3D items that Trevor Young drew up for me. I bought one set in brass and the other in plastic(?). They've turned out to be very good examples but, which set to use. The brass are very slightly more delicate to look at than the plastic but the plastic will, I hope, be easier to fix in this confined space. I thought that I could position them in place and then place a drop of super glue from the end of a cocktail stick at the points where they touch. Capillary action should draw the glue around the contact points and be a neater join that say, using Araldite. It should work (?). I don't think that the brass would fix so well with super glue. Hopefully, I can use the brass set for another project that requires very small springs .

Very glad they have arrived. I was a little nervous the leaf detail would be lost along the way but they look to have printed very nicely. Those indents were only .15mm deep.
I should have made the legs longer to allow positive placement in drilled holes, my apologies.

Another great example of how WT and the G3 community work together to produce another ( in Jon's case YET another!) lovely model.

Mike
Thank you, very flattering

Trevor
Yes, I'm very pleased how they have turned out, thank you. If the legs had been any longer, though, I wouldn't have been able to get them into that space. As these have turned out so well, do you fancy having a go at the loco springs? Just a thought.

Great construction Jon, a tender with character, and Trevor’s springs, add to the detail that brings it to life.

Here are some pictures of the springs for the loco and it's axle box guides.
The springs were drawn up by Trevor Young and forwarded to 'i.materialise' for printing. They've were polished before sending out but, thankfully, not too harshly.
The axle box guides were very kindly cut out for me by Jamie Page, following a twice size pattern that I sent to him, on his pantograph. There are two guides per axle box, one on either side of the timber frame, with a spacer in between each pair.
Thank you very much, both of you, for doing this for me, it was very kind.

The springs do look good - the detail seems quite fine. What was the service like with i.materialise? I have been tempted to try them as an alternative to Shapeways.

The detail is fine, those leaf details were drawn only .15mm deep. After casting and polishing Im relieved they came out ok.
From what I can gather, unlike Shapeways which specializes (or specializeD at this point...) in an online marketplace, i.materialise requires you to purchase a print before it can even be made a product. However that doesnt stop me uploading a model, choosing all the print configurations, and sending someone like Jon the link for him to buy on his own. Though that does require communication between designer and buyer, and there was A LOT of communication as the prints you see here were the 3rd or 4th revision I submitted as it kept being denied due to supports.
Id certainly be tempted to use i.materialise again for personal work, athough Im also tempted by Sculpteo as they also have some lasercutting services which works well for my line of modelling. If the steel lasercutting is available again that is.

Thanks for the feedback - I'm going to try them with a few items as they've got a "Black Friday" deal all weekend with free postage on any items ordered.

Wasnt aware. May have to place an order for some of my parts.

Neither was I, I'd placed an order earlier in the week but it got rejected on the compatibility checks - so I tweaked it and uploaded the new file for processing. I was just about to hit the submit button when I spotted the banner ad for the free postage. So now I'm frantically trying to finish off a couple of other little test pieces!

Back to the tender to produce the brake shaft hangers. I had to take one set of wheels off for the fitting of the hangers which exposed my springing arrangements. I fixed a pin, that had a little collar silver soldered to it, into the top of each axle box.(is it axlebox or axle box?) A hole was drilled into the frame member and a small coil spring dropped in. When all is set up, the collared pin pushes against the spring giving the necessary springing and also giving the illusion that the dummy spring is doing the work. Yeah, the collar is a bit wonky but it still does the job and although the pin looks as if it leans, it doesn't. It took me ages fiddling about with different springs until I got it right but the effort was well worth it. When I get onto the loco, I'm going to attempt the same sort of subterfuge.

 

[Spitfire2865]

Very clever arrangement. Now I see why you didnt want an overlong center pin.

This is as far as I'm going with the construction on this one. I did try and make some brakes but, it's all a bit cramped to be able to get things fixed in place and I don't have scale fingers. This is one project that needed thinking out from the very beginning and the brake hanger brackets should have been fitted when that particular beam was just a stick of styrene, never mind, eh. The last thing I thought needing to made was the coal door but I couldn't find any information/drawings to show this. So, I got out the DVD of the Titfield Thunderbolt and low and behold, there wasn't one fitted! That saved me a little job. The buffers are turned from Box, my favourite wood for turning, and will be either stained or painted black. Also, the tiny coil springs need some adjustment as the tender is 'leaning' forward as they are. Apparently, the loco is lower than the tender and the fall plate is bent down to meet it but I won't know by how much until the loco is built.

Managed to get some primer onto the two parts of the tender but, couldn't manage to get very good photos though.

It needs a dent on the front drag beam where it ran into the back of the loco, In the film, ( they say the tender was damaged from that and it is still on the tender today ) Must have a look one day,, Cracking workmanship, Can not wait to see the loco build.

This is the under frame with some Halfords matt black sprayed on this afternoon. The paint is still drying which is why it has that sheen. Having said that, I did um and ah over whether to use matt or satin as mat can look a bit dead sometimes and satin can dry too glossy but I went with matt after all. I had to adjust the picture by lightening it so that the black would show which is why the pictures look grainy.

I forgot to take a picture of the tender masked up. It was masked with Tamiya tape and tissue paper. It was suggested that al masking was removed as soon as the painting was completed. This was carried out very carefully with a pair of tweezers. No mishaps occurred during this operation and I'm very pleased with the result. I used Rover Brooklands Green from a rattle can and it went on okay. It shows quite dark in these pictures even though I used the flash. I expect that on a sunny day standing on some rail it would look okay though.

 

[Arty]

Looks very good Jon.
