Potty Popcorn Engine
sbwhart:
Finished off most of the fittings for the manifold.
To make the body for the whistle valve just square up a chunk of brass and put a small centre where the coupling will be turned.
Then using the good old wobble bar get it on centre in the four jaw chuck
Turn and thread 1/4*40 and drill through 2mm and part off
Over onto the mill and mill a 3/16 slot across it.
Drill a 1mm hole for the lever pin
The lever is made from some 3/16 square mild steel bar, so in the self centering four jaw with the compound slewed over a couple of degrees turn up a nice shaped handle, and part off.
Drill a 1mm hole for the pivot pin.
Next bit the valve spindle, from a bit of 8mm dia stainless, centre drill and with a running centre turn and thread.
Flip it round and turn and thread the other end again using a running centre, to turn the cone I used a small fixed steady that I made some time ago it just clamps on the running centre.
These are the bits
and assembled
Cheers
