http://www.instructables.com/id/HomemadePlastic/ Plastic Smithing: How To Make your own HDPE Plastic Anything (DIY plastic lumber

All you really need for that is an electric oven (or other kind of oven if electricity is available, you just need to be able to control the temperature precisely and keep impurities out) and a compression mold in a shape similar to a lego brick (pegs on one side, holes on the other). You make the side-walls on the mold taller than the finished block will be thick so that you can overfill the mold slightly. Put it in the oven and heat it up until the plastic is thoroughly melted, then put the top plate of the mold in and crank it down. The top plate should have relief holes to let the air out. Once you stop getting air and start getting plastic, you screw some plugs into the holes, and then put some more pressure on the mold just to make sure it all sticks together well. If you use a consistent weight of plastic every time and crank it down to a fixed point, you should be able to get a reasonably consistently sized block.
