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 :beer: Stew |
