I have successfully constructed a mold for a perfect De Laval nozzle !!!
I took a 38 mm wooden dowel , and drilled right through the center as best as I could.
I then jammed the drill bit in , and used the drillpress as a makeshift lathe....Worked really well ,the shape is there.
I've also cut it at the 'throat' , and re-lathed it smooth , so the mold comes apart.
I'll take my camera to work tomorrow and snap a shot.
