LEGO?

[ALfooy]

As this was the closest to 'toys',i thought i'd post it in hee, i honestly have a hankering for more, i just wanna make a load of lego cars again=D anyone else have the same urge LOL

[Ordinary Bloke]

You're on your own...

but I want all the wheels

[motormania]

I used to have the early techno logo road car with working gears and 4 pot engine, great stuff.

Trouble is, lego really is for kids, RC is more fun for us oldies

[ALfooy]

yeah i know, i still think legos cool thougth, i mean i've got a tamiya R/C skyline GTR JGTC, loads of scale models and think i'll start buyin airfix again, but i just still like lego lol, guess i'm still a kid:P

I may have built the big batmobile and have part built the large technic 06 ferrari f1 car.

I fancy the big death star and millenium falcon as well.

I love LEGO. I use it to cast more model bits!

[SkinnyBoy]

ive ordered the number plates "LL918" only original lego geeks like myself will understand the significance of that number haha!

I've been scouring ebay for months collecting my old space lego, and reclaiming my lost childhood, which wasn't lost but traded for a ropey electric guitar... what a fool i was.

Do it. The falcon is the next on my list!

[Dundarachtwo]

yes well actually erm collect lego trains....

can take photos if you dare admit youre as sad

[BlueMR2]

Nice, the big destroyer seems pretty cool. I fancy the Millenium Falcon. £350 in one go though, and its pretty huge to fit somewhere as well, lol. If they just reduced the price abit.

Lego is the biz!!

[donz29]

Yup, nothing to be ashamed of in admitting you enjoy lego! I was re-introduced through my 5 year old son!

[PeteG]

I've got boxes and boxes still under my stairs... only thing is, they're all mixed up... one Sunday, I'm going to build a giant Lego city...

How does that work then? I need some bits in 1:18 & it looks like I may need to do them myself.

It looks to me like cinqster is using the lego to form a frame for vac-forming new parts (judging by the holes in the bottom) so he would place very soft (warmed) plastic sheet over the parts and then switch on the vacuum cleaner that has it's hose attached under the frame and the warm plastic is pulled tight over the original parts replicating their shape. You just need to cut them out of the carrier plastic.

The alternative is to place your parts in\on (depending on shape) some plasticine in the bottom of the Lego frame and pour some RTV Rubber on top. Once set turn upside down and repeat with the rubber - remembering to include pouring points to the parts. Once set pour hot metal or resin into the pouring points and allow to set. You then just need to remove the "sprue" formed by the pouring point and clean up any flash.

Yep, you have it! This was the start of a two part mold. The white rods are the pour and vent tubes - when the resin is poured these will form two sprues that need cutting off. The holes in the plasticene are registration holes so the two rubber mold halves will lock together. I use an RTV rubber and catalyst that's mixed 20:1 by weight - easy to use. The RTV rubber is poured over the parts to fill up to the top of the second Logo course and allowed to cure for 24 hours. When cured the Lego box is flipped over and the plasticene removed. If done with care the model parts should stay firmly in place in the one mold half. RTV doesn't stick to most things apart from itself. The joining face of the cured mold half must be coated in a release agent - I use Vaseline cut 50/50 with white spirit and paint it on the mold surface. Give it 30 minutes to let the Vaseline mix 'skin off' and you're ready to pour the second side of the rubber mold. Finally, go for a good quality resin to cast with and when the molds set you can be popping out new parts out every 15 minutes. With practiice you can get really good join lines comparable to commercial kits with no flash and little parts clean up needed. Let me know if anyone needs more info!

Here you go...forgot I had these pics:







These parts are destined for a tuned 1/6 Monkey Bike. It'll be getting Nitrous too!

I'll see your engine, and raise you a computer.

Lego rules.

Peugeot could learn about a thing or two about car roofs from this lego model. http://www.youtube.com/watch?v=q-aysbTL7VY&fea...
