28. Feedstock Inlet
5.3 Feedstock Funnel
The inlet needs a wider mouth to make feeding easy. A funnel can be made from a sheet of scrap metal.
Cut one horizontal side longer than the other (115 x 35cm); the other sides should be angled (20cm long).
Bend over into a funnel shape and 5 drill holes which line up for riveting. Rivet together.
5.4 Residue Outlet
The existing inlet to the large tank can be used for the residue outlet (approximately 88cm from the floor
to the centre of the hole.) However it must be widened to 4” (the method is explained in [5].)
