RMweb Gold Donw Posted August 23, 2016 RMweb Gold Share Posted August 23, 2016 Dont forget to check what the the crank throw of the wheels are. It could be the cylinders are longer to match the crank throw. Model Wheels are often a compromise. It may be noticeable if the crosshead is travelling a greater distance than the length of the cylinders. Don Link to post Share on other sites More sharing options...

Would be embarrassing to send time making new ones only to find the travel of the piston rod thingy can't be accommodated. Link to post Share on other sites More sharing options...
RMweb Premium 2ManySpams Posted August 23, 2016 Author RMweb Premium Share Posted August 23, 2016 You have really made a big difference to the look of the loco. I am afraid I am in the camp that says replace the cylinders. If nothing else had been done to improve the loco I think they could of been left. You should also check the relationship of the cylinders, slide bars and motion bracket. Cylinders of the correct size and position may effect these if they were altered to suit the kit. Another good point. The motion bracket, which I amended two years ago is in about the right position. Not 100% sure about the shape. The slide bars are just wrong. The cylinder as I have it looks to be about the right angle, just the wrong size and shape. Comparing Rice's drawing with photos, I'm in two minds as to whether they are a tad under diameter on his plan. They look meatier in pictures. Might experiment with tube first... 2 Link to post Share on other sites More sharing options...
RMweb Premium 2ManySpams Posted August 23, 2016 Author RMweb Premium Share Posted August 23, 2016 Just remembered to check the piston stroke. Just less that 12mm. Shorter cylinders should be fine, even with a few mm each end. 3 Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted August 24, 2016 RMweb Premium Share Posted August 24, 2016 Don't forget that the outside of the cylinder will be at least two or three inches greater than the piston diameter. Link to post Share on other sites More sharing options...

Guest Isambarduk Posted August 24, 2016 Share Posted August 24, 2016 "... they are a tad under diameter on his plan.

It doesn't take much to make a huge difference in their appearance. David Link to post Share on other sites More sharing options...

RMweb Gold The Stationmaster Posted August 24, 2016 RMweb Gold Share Posted August 24, 2016 Yes please Mike. Are they the same as the 1361? Ah, you've sussed my source. The internal dimensions are the same so I'm firmly betting that the outside ones will be too as the cylinders look the same - currently unclad but basically just some bits of tin to wrap round them so I'll try my contact to get the measurements checked. Unfortunately the original 1361 drawing i obtained might be in China so I'll not try that route.

RMweb Premium 2ManySpams Posted August 27, 2016 Author RMweb Premium Share Posted August 27, 2016 Yes I know, it needed a good clean, so it's been down to the kitchen sink for a good scrub with Viakal.

John R Smith Posted August 27, 2016 Share Posted August 27, 2016 Trying to decide what to do next? Perhaps injectors, tank supports, sandboxes - all the stuff where the handrails might get damaged if they were already attached. Then the handrails, maybe . . .

RMweb Premium 2ManySpams Posted August 27, 2016 Author RMweb Premium Share Posted August 27, 2016 Yes that makes sense John. Going to need some fabrication in that case. The sandbox castings are not the right size or shape. Ditto the tank supports. I've not had a good look at the injector castings yet but fear the worst based on experience so far. Putting this lot off, I've gone for filling in all the slots in the footplate. Link to post Share on other sites More sharing options...

Watch the injector overflows and make sure you have correct period photos of the chosen engine as Swindon seemed to be forwever setting out to cause confusion for later generations of modellers with the number of permutations of the overflow arrangement. All very odd after the simplicity of the 1361s. Link to post Share on other sites More sharing options...

Correct Chris - but they seemed to go in all sorts of directions over the years and on different engines - hence the need for a photo of whichever one you're going to take the number from. Regrettably I dumped my list of 1366 reference pics/links when Heljan announced theirs (having done quite a lot of detail research for 'someone else' on the class).

RMweb Premium 2ManySpams Posted August 27, 2016 Author RMweb Premium Share Posted August 27, 2016 Talk about making a silk purse from a sow's ear... That is remarkable, Chris. I didn't know it was possible to make a model (rather than an approximation to one) of the prototype from that kit! Not sure about the silk purse, there will still be plenty wrong with it but I'm hoping the end result will be more representative at least. Link to post Share on other sites More sharing options...

Regrettably I dumped my list of 1366 reference pics/links when Heljan announced theirs (having done quite a lot of detail research for 'someone else' on the class). The pipes on 1368 went through the footplate rather than round it like 1367/9. Thankfully i've lots of clear reference photos to look at for that part. Thought i could get away with using the tank support castings as is but, having fitted one, i'm not happy with it... should know better by now.
