Made the four bearing oil cups (item 65).
Next to be made was the exhaust plumbing. I did not follow the plans here and made individual open ended exhaust for each cylinder. It is made from brass and 6mm copper pipe. Also made the gaskets for them.
Fitted square headed bolts to the eccentric sheave.
Made some bolts which will will look like studs and nuts for the cylinder caps.
Started work on the T-piece.
Used a 16mm brass rod for it and carved out the middle part using a parting tool. Cleaned it up using a left hand and right hand turning tool.
Marked the centre of the middle part with the help of an edge finder.
Using a 6mm slot drill cut the hole for the other part of the "T" piece.
Finished the T-piece. At first I was going to soft solder the two pieces together but I suspected that the solder would go everywhere and make it hard to clean up. So I made the parts to be a press fit together and added some super glue for good measure. Drilled all the required holes on the flanges using the centre mark I had left earlier on as the centre reference.
Made other items for the inlet plumbing.
I managed to bend a couple of pieces of 4mm soft copper tubing with a bend radius of 6mm. This was done manually around a 12mm brass rod as I do not have a miniature tube bender. Maybe I should make one someday.
Also made another flange and gasket which will fit to the globe valve and use it to connect to the compressor.
I made the last two parts of this build, namely, the steam inlet glands (item 23) which bolt to the steam chest covers.
Next, I started work on the inlet manifold. All the parts were previously done. First I trimmed the bent copper pipes to length. To make sure that the free ends of the copper pipes face each other I put a 3mm drill in the pipes and glued the other end to the mounting flange.
Glued T-piece and added globe valve.
