Over the last couple of days I've made the Turret or Manifold to none steam people.
But first to finish off the clacks, the balls need setting down to do this take a new 3/16 stainless ball bearing put it on the seating, and with a brass drift give it a sharp biff with a light hammer, throw the ball away as you've distorted it, replace it with a new one. Now make the cap first measure the depth to the ball and calculate the length of thread required to allow the ball to lift 1/32 ".
Here we are one done No two measured for the cap.

Now for the turret this is made from phos bronze I've bin using calphos which is a leaded bronze that machine very nicely. The body of the turret is made from a length of 3/8" dia material:- drill 1/8 27mm deep and drill and tap 3/16 * 40 ME 5mm deep the body uses a 1/8 steal ball valve for the whistle so the bottom of the 1/8 hole needs to be square and accurately depthed, so I made a flat bottom drill and set it to depth to the chuck face against a steel washer, and just kissed the bottom to bring it to the correct depth.

3/32 hole drilled right through the bottom for the plunger.
Keeping the job on the bar transfer to the mill in spin indexer, and drill the cross holes 3.5mm to locate the fitting for soldering.

Back onto the lathe part off to length flip it round and drill and tap the back end 3/16 * 40 ME
The fitting as there were 4 to make 1/4 * 40 turn up a length of bar enough to make all four and thread it with a die.


The turn up a 2mm long boss for a tight fit on 3.5mm hole drilled in the body part off

repeat repeat repeat.
Then flip them round in a collet:- face centre drill and drill a 3mm hole part way through.

Turn up the other 5/16 fitting
Here they are assembled to the body.

And fluxed with a little nugget of silver solder waiting for some heat.

Again sneak up on it with the heat the flux will go white then black then it will melt more direct heat until the solder melts, pickle for 1/2 hr.
Then set up in the mill and with the aid of the 3mm pilot holes drill through into the body. If you stick a bit of wire down the hole you'll feel/see the drill start to tickle it when it breaks through.

Set the ball down on the seating as for the clacks.

Then make the whistle lever thing sorry this is the only pic I took.

And her we are turret finished.

With the bits made I can now see the best way to fit them on the back head, I think I'm going to black the bush up on the left next to the water gauge and move the boiler feed clack to the top right hand side.
