All frame work was mig welded and made from either 2"x2" tube or 1"x2" steel tube.

Step 1: Welding Frame Top

Step 2: Welding Frame Bottom

Step 3: Welding Frame Bearing Support

Step 17:

Step 18: Main Frame Done

Step 19:

Step 20: Heat Shield Installation

Step 21: Sheet Metal

I covered the walls by welding sheet metal to them.

Step 22: Insulating

I insulated it with compressed rock wool that I bought from the hardware store

Step 23:

Step 24: Exhaust for Excess Heat

Step 25: Fibre Glass Door Seals

I used high temp silicone to glue the seals onto the frame this helped the heat stay in.

Step 26: Insulated Machine Ready to Run

I used a 1750rpm motor and a 50:1 gear box , the unit is heated by a diesel space heater that brings the internal heat to 400 deg F in about 10 min .

Step 27: 50:1 Ratio Motor and Gearbox

Step 28: First Part Out of Machine

This part used 5lbs of low density poly ethylene pellets at 400deg F for about 40min heat time and 10 min cooling time .

Step 29: Part

Step 30: Finished Part

    Very impressive!
    What do you make the molds out of? I presume with the bottle, you started with a pre existing bottle (Header tank?) as the positive?
    This could be useful to leverage 3D printing to make things like elaborate plastic inlet manifolds - and many other automotive components.
