Compound – Painting


Painting.

 

Hello Ladies and Gentlemen.

Now it’s time for the last chapter in this story, the painting of the engine. For me this is a very funny part, now I can really see how the outcome will be.

 

First I painted the fundament …

Painted_40

…I have chosen a dark blue colour, and I think it goes very well to the polish bronze.

Compound – Equipment


Hello Lady’s and  Gentlemen.

It was a while sense I post an update, I was force to take a break, I was tired off building and it’s not good to build if you are not in to it.

 

But now, I have been started again, this time with the small equipment that connects the steam pipe and so on.

The Pipe Flanges

The pipe flanges is a bronze casting, well done and easy to perform.

Equipment103

After cutting them apart with my hacksaw …

Equipment104

..I mount it on my lathe, centre drill, and drill hole…

Equipment105

…and threading ¼ 32.

Equipment106

I also make a mandrill, treading ¼ 32 for use on my lathe.

Equipment107

Here I clear up the one side, if you look you can see a small centre hole. This is for use later on.

Equipment108

Here I have turned the piece around for clearing the other side …

Equipment109

…and then marked out for drilling…

Equipment110

…and also drilling the hole.

Equipment111

And then some good filing.

Equipment112

And the result, not too bad, right?

Equipment113

This is a little tool I made to fit in the cylinder block…

Equipment115

…and here I’ll just need to mark out where the hole would be…

Equipment116

…and drill and treading…

Equipment117

…and it suit very good.

Next is an extension of hexagonal brass…

Equipment118

…and it needs some lathe operation.

Equipment119

I’ll turn down for threading ¼ 32…

Equipment120

… and it’s a just an easy operation in the lathe.

Equipment121

Then some more turns…

Equipment122

…and begun to cut off…

Equipment123

…but first centre drill…

Equipment124

…and drilled true.

Equipment125

And this is how it should be…

Equipment126

…and here it’s finish.  It connects the steam from the high pressure cylinder to the low-pressure cylinder. This is not as Stuart has drawn it, but I think it looks nicer.

Equipment127

And here mounted on the cylinder block.

There are two more flanges to do.

Equipment128

Equipment129

Equipment130

Equipment131

This is for the steam outlet pip. ..

Equipment132

…and this is for the steam inlet pip.

Equipment133

Next is the cylinder cover. I use a paper as a mall…

Equipment134

…and marked out for the hole and cutting.

Equipment135

Then drilling and threading.

Equipment136

And now the main part of my steam engine is finish.

Equipment137

So far, I feel very pleased, but now I have to demount the whole engine for paintwork and then mount it again. For the last time I hope.

 

I’ll be back.

Compound – Eccentric Rods


Eccentric Rods

Hello Ladies and Gentlemen.

Now it’s time for the head, that connecting the valve road with the eccentric rods.

A piece of mild still in the lathe…

Eccentric_Rods_063

…and some turns and center drill.

After drilling  and cut off…

Eccentric_Rods_065

…then in the mill some more drilling for connecting to the eccentric rods.

Eccentric_Rods_066

Then with an end mill…

Eccentric_Rods_067

…and it begun to look as a head.

Eccentric_Rods_068

Then some threading for connecting to the valve rods…

Eccentric_Rods_069

…and then finish off with some end mill.

Eccentric_Rods_070

After some work with a good fill and some polish…

Eccentric_Rods_071

…and here is how it looks on the engine.

Eccentric_Rods_072

Next the eccentric.

Eccentric_Rods_073

First I have to center drill…

Eccentric_Rods_074

…then some turn on the lathe…

Eccentric_Rods_075

…and then turning the small track on the eccentric.

Eccentric_Rods_076

Half way done.

Eccentric_Rods_077

And now a very crazy setup, I was force to use the cuck from mu unimat be course   I was unable to clamp it to the original chuck.

Eccentric_Rods_078

Center drill…

Eccentric_Rods_079

…and drilled…

Eccentric_Rods_080

… and reaming.

Eccentric_Rods_081

Then drilling and trheading for the stop screw.

Eccentric_Rods_082

And this job was finish…

Eccentric_Rods_083

…and mounted.

Eccentric_Rods_084

Now the last part, the eccentric rod.

Eccentric_Rods_085

First I have to measure and mark out where to cut and where to drill…

Eccentric_Rods_086

…then drill the hole for the bolts before cutting off the parts.

Eccentric_Rods_087

I’ll then use an end mill so the bolts head could fit better…

Eccentric_Rods_088

…on both side.

Eccentric_Rods_089

Then with my hacksaw I cut the part…

Eccentric_Rods_090

…and threading the bottom part.

Eccentric_Rods_091

Some turns on the lathe…

Eccentric_Rods_092

…and then borring the inside…

Eccentric_Rods_094

…and checking so the hole fits well to the eccentric.

Eccentric_Rods_095

Next I have done a little special for turning the track inside the eccentric rod.

Eccentric_Rods_096

And again checking the result…

Eccentric_Rods_097

…then back to the mill for milling the surface…

Eccentric_Rods_098

…and then some more milling.

Eccentric_Rods_099

And now some filling and polish…

Eccentric_Rods_100

…and the result…

Eccentric_Rods_101

…and then mounting to the engine.

Eccentric_Rods_102

Well she is beginning to look like the real thing. It is not so many parts to manufacturing but it’s still long way to go before she’s run.

I’ll be back.

Compound – Steam Chests


Steam Chests

Hello Ladeys and Gentlemen.

Now it’s time to take care of the steam chest. This is a very important piece of the steam engine, it’s truly the heart of the steam engine.

I’ll begin with the cover. The cover has a spigot on the backside so it’s very easy to set up in the lathe.

Steam_Chests009

Here I have set up the cover in my lathe for removing the cast skins.

Steam_Chests010

After that I move the cover to my mill so I can mill the side in square.

Steam_Chests011

Then with a hacksaw I cut of the spigot.

Steam_Chests012

Then flatten the backside.

Steam_Chests013

Now I have to mark out for all holes…

Steam_Chests015

… and drilled the holes and countersink the holes.

Steam_Chests016

I feel quite pleased with the result.

Steam_Chests019

I’ll continue with the steam chests. In the lathe I set up the steam chest in a four jaw chuck and took some turn on the top making the valve rod guide…

Steam_Chests020

… and the bottom for the packing gland.

Steam_Chests021

With a good fill I smooth the packing gland.

Moving over to the mill for milling both sides to the steam chest…

Steam_Chests022

Then I milled both sides…

Steam_Chests023

… and the insides as well.

Steam_Chests025

And now I have four pieces so far.

Steam_Chests026

Next, drilling the holes for the valve rod guide…

Steam_Chests027

…and then using an end mill for the packing gland.

Steam_Chests028

After that I drilled the hole for the steam inlet.

Steam_Chests029

A new setup so I could drill the hole into the steam chest.

Steam_Chests031

After two holes I’ll use bolt and nuts to hold the two pieces together.

Steam_Chests032

And here we go.

Steam_Chests033

Then, using the cover I drilled the holes in the cylinder block…

Steam_Chests034

…and threaded the cylinder block with help of a top hat.

Steam_Chests035

The stem chest with the cover seams to fits very well.

Steam_Chests036

Next, the packing glands.

Steam_Chests037

First I have to cutting of the pieces…

Steam_Chests038

…and the in the lathe for some turns, flatten one side and center drill /drilled a hole.

Steam_Chests039

Then I use a spigot so I could turn the other side.

Steam_Chests040

Marking for the holes for the stud, then threaded and then drilling through …

Steam_Chests041

Steam_Chests042

…and after some good work with my fill I have to check so it fits well.

Steam_Chests043

No it’s time for the valve roads.

Steam_Chests044

After cutting the parts I took some turn in the lathe and threaded the valve roads …

Steam_Chests045

…in both end.

Steam_Chests046

And now there is to more pieces to the steam chest.

Steam_Chests047

Next, the valve.

Steam_Chests049

First in the mill I flatted both sides…

Steam_Chests050

…trying to have a smooth side on the valve.

Steam_Chests051

Then drilled throe …

Steam_Chests052

…and then mill a track in the valve.

Steam_Chests053

And now two more pieces finish.

Steam_Chests054

Then I cut of a piece of bras…

Steam_Chests055

…and mark up for a hole to be drilled…

Steam_Chests056

…and threaded…

Steam_Chests057

…and again check for fitting.

Steam_Chests058

Then with a hacksaw and a fill I’ll got this…

Steam_Chests059

…and it fits well in the steam chest.

Steam_Chests061

And now another piece is finish.

Steam_Chests062

This update took some times, it was radar many pieces to make and they have to be accurate, but nothing bad happened so I am very pleased over this update.

I’ll be back.

Compound – Connecting Roads


Connecting rod

Hello Ladeys and Gentlemen.
At last I found some time to continue my build of Stuarts Compound Engine.  This time it’s the connecting rod, and it is a very important part of the engine. They have to be in straight line, square and the dimension must be exact.

Here is the casting of the connecting road, as you can see there is plenty of material to remove.

First I have to square the bottom end with an end mill.

And after that I have to draw out and mark where the holes for the crankshaft should
be.

Next I drilled the top and bottom end…

… and this is for my set up in my lathe.

It shows up that this set up was not so good idea, so I changed to this.

And now I could finish some parts on the lathe.

Then I drilled some holes for the bolt before I partial bottom end in two parts.

Then I use  a hacksaw…

…and there was two parts of each connecting roads.

Next I drilled the hole for the crankshaft.

And some more turn on the lathe.

This set up looks crazy but it is to help me drilling the holes square for connecting to the crosshead.

After that some milling.

Here I try to round off the top part.

And here we go, two connecting roads are finish.

And then I mounted the connecting roads on the engine.

This was a little tricky to do but another part is finish,  but still there is a lot more to do.

I’ll be back

Compound – Crosshead


Crossheads
Hello Ladies and Gentlemen.
Today I continue with the crosshead, not a major update but a very important part of the engine.

The crosshead is connected between the piston road and Connecting Rods and in a groove in the Crosshead Guides.

The crosshead is a very fine casting made of bronze.


I began with a setup on my mill, and square the part.

Here I have done all of the four side of the crosshead.

Then I move the crosshead to the lathe and make the connecter for the Piston Road.

After center drill, I have to drill a hole…

…and threading for the Piston Road.

So far I’ll get this.

Then some more turns on the lathe for that part that fits the groove in the Crosshead Guides and  then drilling/treading.

And now I can check so I know that it fits well.

Next drilling for the hole to the Connection Road…

…and then I have to mill the edges straight.

And after some filling and polish I’ll get this.

Mounted on the engine, the backside looks like this…

…and then the other side.

Even this miner update was little tricky because all dimension has to be correct and the angel must be straight, in other words I have to do some small adjustment but now I am pleased.   :)

I’ll be back.

Compound – Pistons


Hello Ladies and Gentlemen
Pistons, pistons road and cylinder glands.

Now it’s time to take care of the heart of the steam engine, the powertrain. It’s about the pistons, the piston road and the cylinder glands.
Pistons:
The pistons are casting in very good quality.

The first thing I did, was setting it up in the lathe and took some turn to flatten the top.

Then some more turns to make the 45 degree angle and then I did the edge.

Next I drilled and threaded for the pistons road.

And then turn the casting round and turn the edge, bottom and inside of the pistons.

Then I made a little mandrill so I could mount the piston. Then turn the piston down to the correct dimension and then cut the track for the piston rings.


And here I have done the both pistons.

Piston road
The piston roads are made from silver steel…

…and have to cut off in a proper length and turn down in the both ends for threading.

Then I have to cut down a little bit so that threading fits the piston.

This was a very easy job and it also fits the piston well.

Cylinder glands.
The cylinder glands are made of bronze casting…

…and first I have to use a hacksaw to cut it in two pieces.

Then in the lathe some turns so I have a good surfers and then center drill, drilled and threaded so I can mount it on a mandrill and finish of the bottom side.

Next I have to mark and drill the holes for mounting the glands to the bottom cover.

Then I set up the cylinder, bottom cover and gland on the mill for drilling and threading.

And then testing so the glands fits well.

After a bit of filling and emery cloth, then back to the lathe for drilling and reaming.

And again check so it fits well.

And now another piece is finish on my compound.

She is beginning to look radar pretty, isn’t she?  :D
I’ll be back
