Dragged myself into the shop today and finished off the bits and bobs for the governor:-

Turned up the jocky wheels and crank shaft pully. No pics

Then made the fly ball arms, I used mild steel

Squared up a block and first drilled the pivot hole 1mm and the corner holes.

Then with a milling cutter milled one side deep enough to make the two arms, then swiveled the vice round, and milled the angled bit.

Then split them off with a slitting saw.

Spent a little time filing them to fit, and filed the end into a rough round then run a M2 die down it.

Drilled and tapped the balls

I took delivery of some 3mm dia o ring cord this morning that I'm going to use for the drive belt, so time for another hows it going to look shot.

Ok with my bigger watermark now in place.

Made the manifold.

Started with a bit of brass bar, turn it down to size and part off.

Then drill and tap one end marked the tap up so i wouldn't go in too deep.

Turned it round and did the same to the other end and also thread the OD 3/8*32 ME.

Then mark out where the holes are to go, then in the spin-indexer drill the holes 3mm for the couplings, also milled a small flat on the hole position so the coupling would have something to sit square against for soldering.

Turned up the coupling with a little 3mm nipple on the end 3mm for a tight fit in the manifold.

Couplings pressed in.

Onto the silver soldering just added a little bit of flux, and a few nuggets of solder and heated them up to everything melted in, then into the pickle for 1/2 hr.

Back onto the spinindexer, square up onto one of the coupling pick the hole centres up and drill.

Wilst it was in the pickle made the stop valve nut.

Her it all is
