A Quiet Sunday
Re: A Quiet Sunday
Last one.
This came about from reading an MOD requirement for an articulated twin axle suspension for trucks.
On finding patent drawings and following it through I was missing something. I started building, and finally found the
missing action of the puzzle. Thornycroft used this suspension, plenty of info on the web re measurements etc. so the pics. tell the story. Chassis, steering, front axle ( a piece of brass track) rear diffs and axles set up with tyres machined from plumbing grommets. Close up of the steering box, drag link etc. Rear view showing the patent suspension, upper and lower spring sets brake drums prop shafts and the all important gimbals (the missing link) I actually achieved slightly more articulation than the patent called for as this pic. shows. each axle had to be capable of moving through so
many degrees ( 18deg. I think)with out affecting the other axle. on with body work, starting to look like a truck, hopefully a 1927 Thornycroft A5 RSW (rigid six wheeler) Building the large winch that the army fitted when these were used as gun tractors (became the Tartar) it's front and rear capable. Jumping ahead in time frame,( my railway) those conversant with these things will know that the body is straight off a WW2 Scammel .
Crane works, full recovery gear, snatch blocks, slings, ground spades, anchors, rigid tow pole and pintle hook all carried in the lockers
or stowed on board. Not finished, but then I never finish anything, and it's a bit dirtier these days.

Re: A Quiet Sunday
Wow that is a magnificent project in it's own right, never mind all the other aspects of your railway. You clearly must have at least 36 hours available in each day in your part of the world. Would you please expand on your intriguing statement that you turn your tyres from plumbing grommets, suitable tyres have always been a real problem for most model vehicle builders.

Hi Phil,
Talking to a friend at the GSSU who was into tether cars, said he turned wheels up from grommets, said he'd bring some in next day. I got six and needed an extra one for the spare and thought I'd seen something similar at Clark Rubber. So that's where I obtained one that machined the same as the other six. I can't tell you what they're intended for, just that they are rigid enough to machine like machinable rubber. I even found I could polish the surface. From memory they were about 100mm diam. x 12mm thick and had a hole of about 25mm. An advantage of tyres for that period is they were pretty basic shape wise (many trucks were using solid tyres still) so just a matter of machining the two diameters, putting grooves in and parting off. The sipes went in afterwards by hand with a Dremel with a diamond tipped cut-off wheel.

And have been for me too.

Traffic Pattern? What pattern? Spuds out; grain in, but cattle, sheep and passengers are a lot less predictable.

Re: A Quiet Sunday
Not sure what to say other than that is a thing of beauty, a work of art.
Re: A Quiet Sunday
Just to finish off, this is what happens when wanting to see how effective the ground spades were. I set the truck up with a three to one tackle from a ground anchor onto the log skids that used to be at Warringine.
Grant.
The winch is very slow, and I was running the mechanical loco as well and went to change a set of points.
This is what greeted me when I got back, the ground spades work, and the log skids are no longer.Grant.

Re: A Quiet Sunday
wow that's some cool modeling
Re: A Quiet Sunday
It's the fine attention to detail that does it. Plenty of research must have gone into getting the small details right. Those ground spades make a lot of sense when you see them in (simulated) action.

Re: A Quiet Sunday
Thats such a brilliant model...Care to sell it Grant..lol.. seriously though that is a worthy winner of any photo competition.

Re: A Quiet Sunday
I don't think any of us could afford it if the cost of 'expert' man hours is used as the basis for the calculation

Re: A Quiet Sunday
That being said Rik, and with Peters recent discussion in "Off Topic" have you ever wondered where all your railway equipment will end up when the time comes for you to stop using it (if you get my drift). I hope my Son won't chuck mine in the bin, I'll come back and haunt him if he does!.

Re: A Quiet Sunday
Forward planning is essential for such a time when those left behind are in no proper mental state to resolve such issues.
I have already detailed disposal of my collections in my will..... My Rowland Emett models will go to the 'Rowland Emett Society' who are already in the planning stages of creating a permanent museum to house and display examples of his work.
My 16mm items, locos, stock, buildings etc. will be dispersed via sales through 16mm Association or here on the Forum. A good friend will conduct that on my behalf to cover funeral costs.
Not taking offers at the moment!

Re: A Quiet Sunday
I should think not Peter.. Hopefully Anne would know what to do with my small amount of stock, give it to my Grandkids....

Re: A Quiet Sunday
Dan has known for a while that every time he stepped out onto the catwalk to adjust the sluice gate, one day he would end up in the wheel or in the lake!
The timbers were well past their use by date.
As the wheel needed a complete replacement, the opportunity was taken to renew the associated timber work with new Merbau which should see Dan out.
As for the wheel, don't know where we are going with that, probably end up building again from scratch. Still investigating!

Re: A Quiet Sunday
Just thought were there ever metal water wheels?
You could use a rim from a small push chair or child's bicycle?

Re: A Quiet Sunday
They certainly did have iron wheels Tom, I was wondering about a centrifugal or squirrel cage fan as looking more prototypical.
A wooden wheel looks good, wondering about using the outer part of a plastic MIG welding wire spool, there's one 300mm diam. which is the size I need. Thinking.

Re: A Quiet Sunday
I can't recall seeing that building before Grant, the stone effect is just wonderful.... how is it built?

Re: A Quiet Sunday
The Mill building sits just to the left of the water tank at Nayook Peter. I built it using Hebel blocks (Autoclaved Aerated Concrete ) 100mm thick sawed down the middle to give me 50mm wall thickness, painted "bluestone" colours then scratched in the mortar joints. Milled out window and door recesses with Acrylic windows and timber doors.
It normally looks like this with the wheel fed by a sluice box that re-directs water from the waterfall on the hill behind it. Timber framed roof, galv. iron nailed on then covered with my own corrugated iron sheeting.
