GnEWBIE Snowflake Entry

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

WOW! What a great invention! :!:
I hope you are going to keep us updated with a photo (and video) when you get the bird finished and working. Your metal work skills are great.

G'day Eee Bee

Looks as if your metal working skills is up there with my electronics.
Looks as if your electronics is similar to my metal working skills.

Just glad we are not all the same but I do wish I could emulate your metal bashing a bit closer :D

When do you expect the bird to fly :?:

Cheers

Hello old friends! Hope you are all doing well. :D

The heatwave here finally broke for a couple days and I was able to make it out to the garage to work on my Snowflake Entry, which fortunately hadn't melted away...

First thing I did was to make sure the elevator will fit in the central shaft:

Good enough.

I do believe my brain completely liquefied during a run of 102F days we have had here, so I decided to stay away from mechanical things until it re-coagulates. Instead, I began stuccoing the outer support columns with Durham's Rock Putty. I hope the texture will give the model a sense of scale while allowing me to make progress without using my brain too much.

Image

Very relaxing, smearing mud onto foam core columns. I could get used to this.

It's very nice to be back. I think I'll catch up on the rest of your projects now! :D

I took an old dome from another project and put it on top of the tower for now, just to get started thinking about building again. It might not be quite right for this design, but I was hoping it might help me kickstart the project.

Image

Then I started building architectural outcroppings from foam core and card stock and attaching them below to see what they look like.

I'm not sure yet which ones will work, or how they go together, but they can always be recycled into the next project. :)

It's great fun getting back into this and the hot weather isn't supposed to return until the weekend....

Glad to be back! :D :D :D

Each new photo is more mad than the last! Keep up the truly excellent work. Looking forward to seeing more of this layout in the future.

Wow, a serious amount of detail work in those buildings. The do look great!
I like the way you can just pin them together to see how they are going to look.

Looking absolutely fantastic :shock: :lol: .

I love those "Architectural Outcrops".

I await developments with eager anticipation.

Agree with the many accolades relating to your layout EeeGee, however returning to the Greek Hero's engine which I previously missed - the invention was made some 1700 years before anyone else started dabbling with steam. :roll:
So little time, so many ideas!!!!! GerryB.

Hello EeeGee -
I love the little Hero's Engine. Could you please give more details about the alcohol burner and the bottom bearing? I too would like to see a video of it in action. Could it be geared down to generate more force?

Thanks for all the kind words, friends! :)
I got more done this weekend and will try to post later tonight.

In the mean time, to answer some of the questions asked about my Hero's engine:

Making alcohol burners from beer cans has become something of a science for budget-minded backpackers, and I found all the information I needed to get started here:

http://zenstoves.net/Construction.htm

It's really trial and error. For me, the answer was more holes and more fuel, since I don't need to pack my engine into a remote location I don't need to be very efficient. (I do like the idea of climbers who bring Everclear for their fuel source. That way, they can drink more and cook less or cook more and drink less as the spirits move them!) :D :D :D

As for the bottom bearing, it's just a 5/32" steel rod filed down to a needle point to minimize friction. I fabricated a small brass disc with a dimple in the middle to put in the bottom of the stove so the needle doesn't bore through the aluminum.

As for power - I originally planned for two sets of step down gears, but found that they actually produced too much friction. If you wanted to go with smaller steam ports (and therefore more pressure) you could probably increase power, but this is as small as I wanted to go without a safety valve. Hopefully, my flapping wings won't require too much power if I center my pivot points on each wing, so each is like a well balanced teeter-totter.

I'll try to shoot a video next time I fire it up!

Hello Fellow Gnatters!

Just a quick note. I got the chance to spend some more time on the architectural outcroppings and thought I would update the photos:

As much fun as I am having with the buildings, I know at some point I will need to get started thinking about building trains. :?

Luckily, as I work my way through the Gnatterbox archives I am finding a lot of inspiration in the projects you all have built or are building. :D

Looking forward to more work and to following all of your excellent projects! :D :D :D

Onward,

EeeGee

Wonderful work. Such a treat to see work in the same mould and to the same standard as Chris Walas.

Eee Gee, What a delightful abstraction of the classic monumental sculpture that grace many towns.
