Hi all,

Had a thought of using lego to create a mold for castle walls with expanding foam:



Set it up with some paper taped to the top to protect overflow. When they say it expands 300%, they're right!





Ended up with a big cavity. Looks like it needs air to expand and as we had a void, it could not grow into it.



Ended up with a good lego texture on the foam in parts:



Although overall, we rolled a 1 - critical failure...

It might be an idea to go smaller, and cast parts that can then be put together into a wall.

It looks like poppa nurgle made that castle

Fill it in with water effects and static grass and call it ruins. not too much of a failure.

You know, try this a few more times. I think you may be onto something. Hell of an idea, sometimes they just don't work out at first.

Exactly, it still has potential as a cool piece of scenery, don't think of it as a failure..just a deviation from the original plan.

Would a lid help?
Perhaps that would force the foam into the cavities.
Perhaps try drilling 'air holes' every 3rd/5th brick?
As far as fixing the cavity for the moment. Try skinning it with an irregular piece of plasticard and treating to look like ivy/vines?
There is definately something in this technique.
I'd say it could be useful for hive infested buildings a la Aliens?

Or may be use lego technik bricks with holes in every third row..
Shaving off any foam the went into those holes would be easier then filling the void

Personally I'd recommend trying it with plaster. Plaster of paris is pretty weak, but hydro-stone is very tough and would probably fit the bill excellently.

Hydro stone....i've never heard of that. got a link gordino?

I might try using the foam that doesn't expand as much. It will take more foam and probably more money, but should work better.

Take pink foam, cut your wall section
Draw brick lines with a ball point pen, lightly indenting
Roll a round, rough rock (about baseball size) across the entire surface
Paint, wash, drybrush
Cheap/fast wall

Cool howto AoE - that looks good.

I wanted to try this out after the initial thought.

Plus, a sheet of insulation board in my area costs $100!

;-)

(no snow here, so I don't think they are heavily used like they must be in NA).

Where? seriously what store. i'd bring in evidence and call them out on that. a bone (term for 100) for as piece of insulation is insulting.

This technique demands furhter experimentation to perfect it but the potential in it cannot be ignored. I am stealing this one to screw around with it and see what it takes to make it work. It'll be about a month (the sigh) before I can get to it at the least, but I'd love to read what else others get up to with it in that time.

Great job thinking out the box. I really like this technique. I'll even credit you with it. I'll call it the Fortress of Tim

There are some who call me "Tim"

;-)

holy friggin frak! there no WAY your looking at the right stuff. I know for a fact because we are both in America. Goto a lowes or a Home depot, and go in the wood/insulation isle and start looking. You can get that stuff for between 20-40 bucks. I know they ALL should have it irregardless of where you live because in building a home its ILLEGAL not to use insulation of that kind.

I'm in Australia - we have a requirement to have an insulation level of 2.5R (I think that's right) which tends to be done with sizilation or commonly fibreglass wool.

Anyone in Australia know of a supplier (Melbourne) for blue/pink foam?

Cheers
