"It" comes to life again

Call the exorcist, I dare not use "It's" name.

NIce to see a plan, Dean.

I prefer "more like guide lines" than actually calling it a plan per-se.

It's a butchered quote from Eisenhower.

In the real world things happen and the best laid plans go wrong... but the process of thinking about the problem and making your plans means you are prepared!

And the equal and opposite effect of some of the most spontaneous and simple ideas can end up working very well.

Once again I have an update- the main rods, crossheads, valves and pistons have been completed. I view this last bit truly as the calm before the storm, following this I will be attempting to animate the valve gear following drafting it.



In the past I had a great deal of difficulty trying to animate a Stephenson's valve gear, however, I don't think that I shall have the same issue with this design. Naturally, I will create a video for it on YouTube when I am done.

I have been fortunate enough to find a fair deal of the older magazines I require for this project on eBay. I'm afraid my study will begin to resemble an archive in short order. Despite having made some progress in assembling the older volumes of Model Engineer, I have yet to complete a single volumes worth of them. Presently I am focused on the 1930s.

Whilst I was organizing my new (in a manner of speaking) purchases, I did peruse a few briefly. It's a shame that 2.5" gauge is practically extinct in the US.

Until next time!

The valve gear is beginning to take shape rather nicely, I really do hope that I can animate this one successfully.
It's certainly been one of my goals to say the least! Hopefully I will have the same lucky with Zoe in the coming months.

Before I start on the boiler for this locomotive there will be some work on a few smaller projects I will post on here. The wagon for Tich, and Mini-Steam Plant come to mind. I've also been considering altering a couple of Curly's designs for gauge one to appear as though they are half inch scale- since I do have a penchant for narrow gauge and have the space for an oval in gauge one in my back yard. Time will tell!
Perhaps it would also work as a good excuse for me to build Zoe and Jack Horner.

Regards,
-Dean

Nice work Dean, looking good.

A wagon for Tich sounds like a fine idea! wink

Typically, I would prefer to do an update every other day. However, today I achieved something I had yearned to figure out in CAD for quite some time- animating the Stephenson's link valve gear.

Do remember that the reversing assembly is not installed, the eccentrics are simply attached to the axles with no real regard for attempting to time this locomotive properly, and I had to remove parts in order to allow my computer to animate the lot of this smoothly.



The more I look at it the more I realize that there is going to be a fair amount of touching up for me to do- more to follow!

I must admit that I am still rather surprised that I was able to get the valve gear to work. I have smoothed it out considerably and make it behave in a more realistic fashion- alas it's still not perfect. Then again, that really isn't the point to what I am doing here- so I shall not fiddle about with it longer.

Here she is, with out the reach rod installed or anything of the sort that would go in the cab (which comes next).


Of course, the frames are removed for the purposes of this rendering.
I have decided on some proper colours for this locomotive- despite being a Hall class I do feel that Ivy Hall looks better in British Railways black. Ergo, I have decided when it comes time to add some colour (in a manner of speaking) to this project, I shall end up going with a darker scheme such as this:



I cannot stress enough that I am not entirely sure that this will turn out correctly, if I am not satisfied with it I am certain it wouldn't look all that poorly in green.

In other news, strange circumstances have come to pass that means that there will be potentially TWO small scale live steam tracks cropping up with people that I know at the heads of them. Both are interested in 2.5" gauge, so Mr. Redsetter might finally actually get his wish to come true.

However, there is one peculiar little locomotive for that gauge that was not designed by LBSC that strikes my fancy a little bit which I will end up drafting. I doubt that it would take long to draft, so it could end up an intermission of sorts for a larger drafting project.

I hope that everyone has enjoyed my renderings so far!

Thank you Neil, this is the first time I have been able to get this to work digitally for me.

I would greatly appreciate any input regarding my choice of colours for Ivy-from anyone who has bothered to read my posts.

The valve gear is now safely completed, I even started on the blast pipe, still have to do the nozzle.



The part I am still frankly a little amazed at is the reverser DOES function in CAD, as does the valve gear. The current video I have of it in action is really... bad. This model is incredibly demanding on my computer, as a result there is some hanging in the movement of the parts.

All the same, here is the reverser.


Being perfectly frank, I am not at all looking forward to the lubricator. I am just not feeling optimistic about getting it to work correctly, however, that is not going to stop me from making an attempt.

Before I take a pause from working on Ivy Hall, I will finish up one quick LBSC related item that I have been asked to draft-something very useful for anyone that owns a tank engine to say the least.


It's a little tender of sorts for Tich- made to look like a wagon. It would make an interesting basis for some simple, LBSC-esque rolling stock.

I have ran into a problem with a locomotive I worked on before, and I would like YOUR input if you would be so kind as people that might possible read what I write in here.

What colours would this little devil look best in?


Any input in this area would be outstanding!
Until next time!

Been following this thread with interest, even though unlikely to ever build an LBSC design. Your speed and accuracy in 3D cad are simply outstanding, makes my 2D efforts look like Prep school colouring-in.

Regarding colours, i like the look of Ivy Hall in black, makes a change from the usual GWR green and makes it look a more 'purposeful' loco.

As for the 'little devil', i assume it is intended for children so something bright and breezy, maybe post-box red boiler with maroon 'cab' and frame and with black wheels and motion? Chimney (sorry, funnel) could be polished brass to match the other boiler fittings?

Looking forward to further progress on the LBSC designs. You might even tempt me to build one (if i ever finish my current project that is frown)

I'm a bit worried that you are running pixels of the same colour against each other. This is sure to lead to excessive wear and worn-out memory locations devil

The 'baby' needs old-fashioned colours, maybe black and yellow like 'Rocket'.

Dean, as others have said, well done.

Colours. I'm finishing up my 3-1/2" gauge Shay, and have a 3-1/2" gauge Brit "2MT" that in reality were black or green, lined or unlined. But, there is one in preservation that is in lined maroon, and looks quite interesting.

Whatever you do with your CAD model building, don't graffiti it!

John.

I remember the old GWR steam in the Chester-Shrewsbury area in the late 50s + early sixties - the GWR engines were still spotless and those in green + sparkling brass were a great treat for eyes more used to the dirty black engines of the old LMS (though there were exceptions eg the maroon Coronation Scots belting through an adjacent line at near 60mph was a sight to see and hear)
