I found a little time to get in out of the heat (its been over 100 degrees for the past couple of weeks in the midwest) and into the basement shop to work on my latest steam engine project.
I have made most of the easy parts so far, I think that I should be able to start the valve and reversing gear next week. I'll keep you all up to date with pics as I go. Stay tuned..
Does anyone know how or what to use to watermark my pictures on an older Mac? Think 10.4 I would like to protect my pictures and intellectual property.

I think your thread title should be "Hey! It's Another Model Steam Engine!" because that is a fine example you've got going there, Sir. Don't forget this is a forum where there is no such thing as "just another steam engine". :old:
-
Jack,
I have to agree with Dennis.
Every little (or large) engine we build is precious to the person who built it, no matter how mundane the subject.
You've making a wonderful job of this one. :cheers:

Engine Looking Great Jack
To add a water mark and size you're pictures you need to down load "faststone photo resizer" to your computer just do a google search, to find the free down load, its easy to use.

I had a good day in the shop today and the part of the day is the valve chest cover. I just happened to have a small piece of cast iron that I milled to the correct thickness plus a little. I used my mini CNC mill to cut the Initial into the front side.
Then I used my mill to cut it to size, and then used the surface grinder to pretty up the face. Then back to the mill to drill all the holes.
Bippity Boppity Boo... the valve chest cover is done and mounted and looks like it belongs there.
Thats enough for today. :whoohoo:
OK now I'm just showing off...

Nice Jack
Is your surface grinder manual or hydraulic?
Steve
-
I got the surface grinder about six months ago, its a Harig 6x12 that I got from a mold making shop that had gone out of business.
It has to be turned back and forth with the big hand wheel on the left while the smaller hand wheel on the right makes the table go in and out, and the crank at the top brings the wheel down a tiny little bit at a time.
It has a pump which forces oil onto all the ways which are rollers that I had to replace because the motor was burned out, its a 3 phase motor rig so that forced me to get a phase converter which enabled me to pick up a old bridgeport mill, but thats another story.

i like your idea of "just another model steam engine"
that sir is a great looking model steam engine!!!!!

Lovely engine Jack....is that one of Ray Hasbrouck's designs?
Bill

Hi Bill
Thanks for the compliment, YES its a Hasbrouck #10 but I am building it half size. Or maybe "Half As!#@" because I am not a real machinist but I did stay at a Holiday Inn last night.
I started to explain my building on that other site but since I am finished over there and by the way, I am banned on Nelsons site. I will have to start over here.

Really like the look of this engine Jack :ThumbsUp:
-
Thanks for showing the picture of your grinder Jack, looks like a great little machine
Steve

So is that a capital 'D' for Jack??? :Jester:
I like the looks of that engine Jack, very robust in nature.

Jack is my nickname not the name that the I.R.S. uses, and the "D" stand for my last name which is Dolde and I have had that name for almost 66 years.
Today the part of the day is the valve which goes inside of the valve chest. I started with a small chunk of cast iron which in its former life was part of an old upright piano. After I squared it up I started to make the valve which involved making several small cuts and then a pocket on the back side and then a couple of angle cuts on the edges.
I am proud of this little part but it did take me about 4 hours to make, but hey the one thing that I have plenty of is time. I am shooting to get this engine finished in about 2 more months, just in time to start another Fall-Winter project.

I finished the internal valve parts and linkage today, now we're getting to the small tricky stuff. SO MANY more parts to make...
This is turning out to be a fun little project :cheers:
Jack

Excellent work Jack.
I really, really, like this.

That's a beautiful engine, Jack! You've realy done a very nice job on it.
Chuck
-
Thanks Chuck and Others
I am trying to do a good job on this project because I am being critiqued by my real machinist friends at lunch. Sometimes they are somewhat judge mental.
Jack
-
I know what you mean by small tricky stuff :ROFL: these old eyes here have a tuff time some times.
Looks like your handling it just fine nice work looking good!
-
Today I made the little part that is the reversing quadrant. A tiny simple little part about 3' long and 3/8" wide with two holes, OH and a curved part as well, I just fired up the CNC mill cut the piece and then put it on the surface grinder to clean up the two faces and then made 2 little spacers so that I could mount it on the engine, and sit sit back and admire about 5 hours of my handiwork.
I told you that this particular build was going to get interesting. :naughty:

I managed to find some time to work in the shop this weekend even thou I had to attend a birthday party and help my son in law haul supplies to his new school teaching gig. You wouldn't believe the stuff it takes to setup a classroom for 4th graders.
Anyway I worked on some of the valve linkage including the connecting rods and eccentrics. I also managed to make some of the reversing linkage. I still have a boatload of small parts to make, but I'm having fun in the shop.
The plan is to have this finished by September 1 .... I think that I will make it :thinking:
-
It's coming along very nicely Jack
Steve

Today I got a chance to make the little parts at the top of the reversing lever. Basically a small aluminum part with a brass handle that is spring loaded inside of it that pivots on a 1/16" shaft and it locks into the curved piece at the top of the engine but I can't cut the notches until I get it running then it will lock into forward or reverse.
Thanks for looking
Jack

Today after finishing the Oil Box I decided to make the Crosshead Oil Ports, a couple of simple little parts out of brass with a radius on one side to match the outside of the crosshead and then drilled. They then had to be silver soldered on to the crosshead and then then the little copper oil lines had to be bent into position from each one up to the oil box.
This project should be running soon

I promised some video :Director:
It won't be long now.
I'm getting close

If I didn't do this correctly Please help an old guy out and fix it, you won't hurt my feelings. After all we all need to start somewhere.
Thanks
Jack :cheers:

I was able to watch it and glad I did.
Very nice runner with a good sound.
I think there's a way to embed the video in the thread but I haven't done it in a while and don't remember. I'm sure someone will pop in with the answer.

Wow, that's a great engine Jack :NotWorthy:
Congrats :DrinkPint:

What a lovely engine Jack, you've made a very good job of it :NotWorthy: :NotWorthy:
I've put right your video.
I'm always a little cautious about running and engine in mechanically by using the output shaft. I have had examples here, made by other people, and I have had to try to put them right, mainly by doing what you did. It is driving the engine backwards from what it is designed to do, and can put unnecessary wear on parts that shouldn't wear. I much prefer to wait until I can put air into it and get it running from there.

Ray would have been tickled pink with that!

Hi Jack,
Great build!
You asked about watermarking on a Mac earlier.
I use iMage Tools, a free download.
You can resize and watermark batches of files with a few simple clicks!
This is what mine look like using iMage Tools.
Just a pic i took when on vacation with my parents in South Africa

Hope this helps you!

Excellent work Jack, looks to be a good runner (and definitely a good "looker") too!! Ray would be proud and I know you must be as well :ThumbsUp: :ThumbsUp:

Jack,
Fabulous :NotWorthy:

I am still playing with the valve timing to try and get it to start up and run better but I don't know if I am making a difference or not.
Sometimes it does not start on its own with very low air pressure, well not to my liking yet. I think the measure of a quality build is how slow it will run.
This little guy eats up a lot of air I can just imagine how much the full size version would have taken to run. I would probably need a giant rotary screw compressor similar to what the jack hammer guys use to dig up concrete, but then how am I going to get that into the basement?
Jack
Oh by the way thanks to everyone for all of the nice compliments. :ThumbsUp:
-
It finally cooled off enough around here to be able to go outside, so I decided to take some decent photos in the natural sunlight. Most of my pics that were taken in the shop are dark.
Let me know what you all think, remember I try to be a hobby machinist not a hobby photographer. :shrug:
Jack

Looks Great! make sure you get that feed pump in.
Dave
-
Lovely :ThumbsUp:
-
Nice! Pretty! Good luck with getting a single cylinder to self start reliably. That's what a finger on the flywheel is for ;D .
Jerry

I finished the feed water pump today, its a little brass assembly bolted to the rear of the engine. I think that it adds a nice touch to a rather outstanding model of the Ray Hasbrouck #10 marine steam engine.
Although I built this engine in half scale it shows well and is starting to run well, nice and slow like it should after I get it broken in on air pressure I will hook it up to my small boiler and then I get to play with whistle.
Thanks for all the nice compliments and for following along.
Jack
