Aloha

I plan on creating a video animation in ho scale. It will involve construction of a highway, building. etc. I will need to make it look like the bulldozers are ripping up the grass exposing the earth. My plan was to take a pile dirt and then spray some glue onto the pile - then sprinkle the model grass onto the earth. My goal is to have the bulldozers rip up the grass and then dig a trench - just wondering it this approach would work well? - and recommendations? Also I was wondering if anyone has any idea where i can find ho scale pipes?

I checked all the majpr hobby sites and ebay

Last question - what paint should I use to paint items to make it look like cement?

I will post the animation once complete - a few months.

Thank you in advance
Sean

Yes, the dirt, water and some white glue (50-50 glue n water) will do the trick. I've done it on a plane crash diorama where the propeller need to rip some grass (defect landing gear) and that's exactly what I did and it worked very well. After, carefully cover those area and sprinkle the grass everywhere else. Just pass your dirt through a strainer to get the samllest grain possible because HO scale isn't very a large scale.:D

For the pipes... go to your local McDonald :eek: and take some straws (hope I'm spelling alright) from the autodispenser... any fast food have these, Burger King are quite large, McD too, maybe a smaller food chain then (I think Wendy's will be the right size) but the point is... it don't have to be those fancy HO scaled expensive (aluminium) tubing. Get a straw and put some Krylon Chrome on it (if you want it to be steel, I would use nato grey (or seagull grey) if you want PVC or CPVC type). Then, a little Red Brown (sorry, all Tamiya color, but anything that look like it will do) dillued in some rubbing alcool (a lot of it... I would estimate the perfect solution to be 95% alcool, 4% paint... 1% chance:D) to get a little rust effect, then the same recepie with flat black. This will be your top coat but some Krylon will still be showing underneat it. After that, take a used blade (X-acto or something) and scrape your top coat (carefully) until some of the Krylon shows up again but not everywhere... only sporadic place will do, you want to give the impression that the steel pipe had been scraped on something hard (like a bulldozer blade) exposing a newly fresh unrust metal. Then, some mud of yours and it'll be quite realistic (mud sticks everywhere). The straws have thin wall and for a HO scale, it's a must (even better than specialist HO pipes). Try to get some paint inside too.

Ciment... I would use a mix of color... all grey oriented from dark to light. Very low PSI (2-5) on a top feed airbrush to make it spit a little... it'll give the grain effect.

My opinion only but that's better than nothing... everything is quite simple to do... on a 1-10 (10=very difficult) scale, I would give it a 3/10 difficulty level.

Go ahead, have fun.:thumbsup:

AOT Welcome to MTF!

For pipes use the common coffee stirers. Smaller than a straw.
To animate dirt removal so the cycle can be repeated over, Glue grass to a curly piece of plastic. Then have the bulldoser move with it as it curls and uncurls.
It would be fun but probably not realistic enough.

Straws can be cut down in lenght... take a pencil to meke them round again after, only matter is ø... choose carefully.

Coffee stirers... we almost don't have them anymore here (replaced by some kind of pasta... like a big spaghetti, and you can eat it after !!) (really)... and the one we have (that are still plastic) are replaced by a weird kind... not compatible with pipes at all. So, it all depend on what you have at hand... but still easily done chose by ø.

The animation part... I let that to the T-man... my ideas weren't taking any consideration of motion in them.

Yup, I live in candy land !!

Dye It

I like your backdrop.
The video looks like a lot of work. Can you make your wheels move more? A dirt stain on the tire would help. I liked the dumping. Somehow you managed to strestch it over a few frames.

Grass color, easy, if Steve can dye RR ties, dye grass, mix some acrylic paint and water, add some grass and strain it out with nylons. Let it dry.
Note this method is untested.
