Something a little different!

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.

Something a little different!

Postby gfadvance » Tue Jan 05, 2010 4:31 pm

Hi , posting couple of picture of current project as much as anything to keep me going to actually finish it.

I know these as "steam" road rollers, although I apply this term to both Steam powered and internal combustion versions .... its an age thing.

Always liked these machines and thought that one of these might go with the crane and loco I have also been building, as I could not find any plans or even dimensions this is pretty freelance. Based very loosely on the Advance manufacturer, date around mid 20's to 30's and one of the smaller versions probable around 2 to 4 tons .... which seems how these machines are classed.

Image Image Image Image

You never know when you start these little projects where the real problems will arise, in this case I thought it would be the rollers but actually these turned out to be pretty simple - the body/chassis which I thought would be easy turned into a nightmare but am getting there now.

Michael .... sorry still using same figure , must, must paint some new ones!!!

Steve, built the box, thanks .... still sorting lighting :wink:

What a fantastic little project...... it certainly looks the part, carries itself very well and has a purposeful air about it.

I think you ought to expand on those "easy" rollers? - How about the front cradle/frame? - that looks pretty complicated - although very convincing. I think I can work out the rollers themselves - although did the surfaces come from a ready made tube or did you role them yourself?

Looking forward as ever to seeing where you take this........ you're certainly cranking out the projects......... I'm still stuck on the crane.

As ever........... fantastic job
KBO .......................... Andi.

That sure is a counter-intuitive situation :lol:

Looks smashing Gordon :D Back in my old highway testing days, I used to go along behind a roller, not too dissimillar to yours, and check it had done a propper job of compacting the materials. I used a nuclear density metre for the job. Stand clear! Blasting! :shock: :lol:

A nuclear densometer, wow ..... just before Christmas I was watching a good old fashioned sand replacement test.

That took me back thirty years to the early seventies, when I was digging holes in road sub base with a hammer and chisel, to carry out the same tests !!

Hi Andi, blame your self for this one - the drilled outriggers on your crane was the look I was trying to achieve with the rollers on this one .. didn't get that close , in fact having posted the pictures not happy with the rear rollers, there's something wrong with them and will probably redo them.

Anyway the rollers are just wrapped paper round an appropriate former, with PVA so they shrink slightly as they dry then the outside was coated with superglue and then burnished with very fine wet & dry ... centres are discs of plasticard detailed with micro strip. etc.

Front cradle frame, think the eye deceives brain .... C channel plastruc, mitred corners with added strengthening plates and then corners rounded .... internal corners rounded with Swiss file to give bent channel effect. Vertical support plasticard then wrapped with outer piece to give
T channel effect ... swivel bearing plastic tube cut in half glued either side then pivot point drilled through vertical web... pictures may help make boring story slightly more exciting !!!

Looks wonderful Gordon. The term Steam Roller is still prevalent here for these machines, even though they haven't been steam powered for more than half a century. I bet most people my age don't even question why they are called steamrollers.

Hi Trevor,

actually don't know/ can't find much info on engine- info I first put on was badly worded, model is based on a Wallis & Steevens "Advance" model

Image

All I can find about the engine was that it was petrol engined. h.p. ? cylinders ? (picture seems to indicate upright 2 cylinder but I would have thought it would need substantial flywheel - and where does that fit ?)

Was tempted to put a version of the Gmeinder engine in it Image
but too lazy ( paint job will improve, promise)

That is a really great piece of modelling. I imagine you have a real sense of achivement progressing this unsual subject. Well done.

Now somewhere I have seen a picture of a small German road roller fitted with hirail wheels that I believe was used to compact cobble stones on an urban passenger tram line. Would it be stretching it to too much on minimum gauge :P :P

Thanks for the feed back folks.

Having been snowed in today, had the time to add some details.

Image

Few things to finish it off . mudguards for rear rollers, piping from rear water tank, steering wheel , etc. Still trying to decide as to whither or not I should add a roof or not?
Then this and the loco and crane will go off to the paint shop .......... seem to remember there is some deadline in February

Looking good Gordon; are you familiar with this Company?
http://www.prestonservices.co.uk/traction.htm
They have some road rollers for sale at present. :wink:
Their yard is remarkable, truly an Aladdin's Cave, anything steam so that includes NG Locos.
I note that currently they have a 15" Garratt for sale.
Les and myself spent several hours there some years ago. You do have to make up a plausible story to visit if you're not a buyer.
Nearby to where I live is the National Road Roller collection though I've never visited the place.
So little time, so many ideas!!!!! GerryB.

More praise to add to the cavalcade - I think this is amazing, takes me back to going to the Hadnam traction engine rally a couple of fields down from ours when I was a tiny lad. Are you going to fill it with lead so it has 'scale' heft?

Thanks for posting the closeups and descriptions of the front roller, especially the tips on the cranked channel frame. I've been thinking about making some skips and this might come in very handy.

Cheers,

Will

Gerry, thanks for the link.

Did come across their site when I was looking for information, in fact got most of my info/photos from them. Also tried to get some additional info from the National Road Roller Association but unfortunately they never replied to any of my e-mails.
