Title: 6 months of work and finally
Post by: slowcoach on September 10, 2011, 07:18:11 PM
Hi, thought I would share a few pictures of the new Locomotive that I have been working on for over 6 months.

It's a 16mm (1/19th) live steam garden railway, Kitson's Leek & Manifold 2-6-4 locomotive. The prototype ran on the Leek and Manifold located near Derbyshire UK in 1904 to the closure of the line in 1934.

Here's the finished cad drawing that I did.

Very pleased with how it turned out  :)

Cheers

Hi Rob very nice indead,

An old freind of mine now passed away made a 5" gauge model of that loco, his widow sold it on to a member of our club who regularly runs it on our track.

 :bugeye:  That looks superb !!!

I'm not familiar with that scale so can you give a clue as to the overall size and the bore X stroke of the cylinders please?

Can't believe that only took 6 months, fantastic!!

Very well done
Locos are not my thing but this is a credit to you :thumbup: :thumbup: :thumbup:
Title: Re: 6 months of work and finally
Post by: slowcoach on September 11, 2011, 05:06:19 PM
Thanks for the kind words guys  :thumbup: Aestus57, the scale of the loco is 16mm to 1 foot and is gas fired and fully radio controlled (2.4ghz). The cylinders have a 9/16" bore and a 5/8" stroke. The total length of the locomotive over the buffer beams is 430mm and weighs in at modest 5kg.
The hardest part was stopping it doing a wheelie, because of its length and the fact most of the weights at the rear :lol: I had to cobble up a weighbridge, using some track and digital scales, with the loco on the weighbridge I then weighed each axle, whilst trying different rates of compression springs for the rear bogie to keep everything on the rails (not easy). The loco will pull just over 20 pounds with minimal wheel spin, and run for about 45 mins. Glad it's done, but I did  enjoy the challenge, right whats next  :scratch:

Cheers

Cracking job  Rob  :bow: :bow: :bow: :bow: :bow: :thumbup:

Did you do all the design work ?  ,,,,,,,,,, what CAD did you use ?

Hi Rob W, Yeah I did all the work on Solidworks and then built one from scratch to prove the (mistakes  :scratch: ) design. It took roughly 6 months from computer to running it round the test track.

Cheers  :thumbup:

Nice one Rob

I thought the CAD had the look of Solidworks  :dremel:

Did you work from an old set of drawings/ engravings ?  ,,,,,,,,,,,,, looks like you must have  in a good few hours at the  computer to model the loco  :smart:WWW

That's fantastic work, and the fact that it took only 6 months is incredible.   :clap:

A lead weight in the smokebox might help with the traction/balance.

WOW - That is a stunning model, really beautiful. And like everyone else, I can't comprehend how you ONLY took 6 months making it, shurely there's 18 months work in it?

I think you need to change your forum name to "express coach"!

Is there/will there be any photos of the build process?

Rob, I used a 7mm drawing and scaled it up to 16mm. I start with the chassis, then boiler and finally the body. It took longer to draw it than it did to make it. But it's worth the effort.



That's fantastic work, and the fact that it took only 6 months is incredible.   :clap:

Funny you should say that Kvom, The smokebox has a huge brass weight on the inside, the smokebox dart holds the door on and the big brass weight. It still wanted to stick its nose in the air  :)

Thanks adev, It used to take me over 18 months to do this kind of stuff, but I guess the more I do the more I gain experience and more importantly confidence (i'm my own worse critic).

Yeah, I will post some pics of the build process  :thumbup:

You are to be congratulated.

That's as good as I've seen.

Superb, Rob  :clap:

While Googling for pics of the original, I came across this which was posted on YouTube a couple of days ago. Is this your creation in action, about half-way through?

Thanks for all the comments guys  :thumbup: spurs me on it does.

Andyf, you have made my day  :clap:. Its great to see on of my engines in action, doing what it was built for and being chased by a cat, I never accounted for that when I designed it, but I will in future  :lol:  :lol:

I going to sort out a few photo's of the construction and I will post them in the project log next week.

Cheers all
Rob

Here's a few pictures of the same locomotive all smartly lined and ready for work. I must add, the owner has done a cracking job on the lining scheme. I can build em, but I can't line em  :scratch:

I thought it had to be "your" loco, Rob, because it looked so new and had the same bucket refusing to be shaken off.

I know nothing about garden railway engines; how is it fuelled?

I see the next one as a military equipment train during war time with machine gunners.  That will keep the cat away.

Hi andyf, It's gas fired with butane or butane/propane mix. The gas tank is located in the rear bunker, a dummy coal load, cast out of zinc hides it nicely. The coal load pulls away revealing the filler valve so that you can re-gas it. To fire it, you open the gas valve in the cab and hold a lighter or match just over the chimney, the gas ignites (small pop  :zap:) and then its just a 5 min wait for the safety valve to blow off (40 psi) and off you go  :whip:

Thats a good idea Russell, I will bare it in mind :lol: :lol:

Cheers
Rob

Rob - am I correct in thinking those look like milk churns on the wagon - if so maybe the cat's after the cream  ::)

Rob,

After my initial awe, especially after watching the video, I got looking closely at the motion. :jaw:

How the ****...on earth...do you work so small?  :bang:

Reaming at that size needs tools made with a microscope! :bugeye:

If you can give any hints and tips I would be very grateful, as I am sure some others would too.

Hi Andy, Yes they are some small bit and they all have a job to do to make the thing work. All I can say is that you have to be good with a file  :dremel: I'm getting a few pic sorted out, detailling the build. I'm still new to posting stuff that makes sense to others  :scratch:
Title: Re: 6 months of work and finally
Post by: AndyB on September 22, 2011, 06:52:26 AM
I am looking forward to your posting.

I have a Benson's Vertical Engine to build but it is a lot smaller than I expected  :doh: and I am afraid of some of the bits as they are so small I can't pick them up in my fingers :(

Andy
Title: Re: 6 months of work and finally
Post by: slowcoach on September 22, 2011, 08:21:21 AM
ooh, I would love to build the Benson Vertical  :drool:, it would make a nice winter project  :dremel: This one isn't mine, I found it on utube.It's a Magical little engine to watch, so smooth in operation.
Andy, did you get yours from Bruce engineering?



Cheers

Hi all,

That's the one, from Polly Model Engineering, as you say Joules.

It has got a lovely motion but I need to build a whole lot of confidence and small tooling before I do any more than the column and flywheel... :(

Getting on with the Rider Ericsson at the moment.
