Yes I did see it. I looked on Thingaverse and there are quite a few 3D printed steam engines. Some are too simple for my taste and some are too complex for my printer. At this point I am in the process of printing the internal gear just to see how it turns out. If that turns out I will think...

I am a firm believer in keeping active and continuing with what you enjoy. You are a little off on the age though. I am only 84. Also I am not sure what would happen with my marriage if we were together 24/7. I don't tell her how to make quilts (about 75 in stock) and she does not tell me how...

The advantage of the 3d printed gears is that we are not limited to the usual sizes of cutting tools, but can adjust modules to any odd size and as long as Gordon will keep the crank throw and the ratio constant he can go for a larger tooth size wiht a smaller tooth count True. There is no...

Why do you want to make another engine when you sold off the first one? I sold 20 different engines because none of my daughters/son in laws/ brothers/wife etc. have any idea what any of my engines or machines are for or what they are worth. I am sure that when I die they are not going to have...

I just looked at Amazon for metal filled filament. This is 60% brass powder. It does not make a machinable print but it can be polished so it could be used for appearance on a model. It is also available in stainless, iron and copper. It is about twice the price of standard PLA for half the...

I made some 3D printed gears for my South Bend lathe which lets me cut metric threads. I have used them a only few times but they have worked well. I have not looked into metal 3D printing but as I remember there was a way to do this in a home shop using a high temperature kiln. If there was a...

And how many times have you, and most of the rest of us said that we have all of the machines that we need. Just in the last several weeks you have purchased a powder coating system, a toaster oven and a sand blast cabinet. :)

I am going to try it. I am not out much if it does not work. I have not looked into having parts printed in metal and perhaps I should.

I was not planning on running it on steam. I think that I will try it and see how things work out. I am a retired old fart and I do not have to make money on my projects and I don't have to answer to anyone else. Well other than my wife if I come back in the house before 3:30.

Have any of you 3D printed a steam engine. This came to mind when I was working on the internal gear for Elmer's Geared Steam Engine and it was suggested that the entire engine could be 3D printed. Is this possible to make a working model of this engine? I would assume that some things like the...

I have the internal gear drawn and I can draw the spur gear with no problem. Have you or anyone else made a complete 3D engine like this? I would think that the cylinder would be the most likely to be a problem. The axle would probably still be made from steel.

I am working on drawing the gear so that I can 3D print it. I would be interested to see how a completely 3D printed engine would work. I may try that. I had not thought about that.

Mine has a dial set to "bake" then a temp setting and a time setting so I set it to Bake/400°/15 minutes. It also has an option to stay on so you could just time it yourself.

I wonder about making the gear with my 3D printer. I made a gear for my Covel band saw a couple of years ago with ABS and it seems to be holding up to my rather limited use. Obviously the gear on the Elmer's geared engine would not be subject to a heavy load or extended use.

I had not thought about making it in three pieces. I have the Mod cutters so it is possible. Making the external gear is easy and I will have to think about this method. Like most of us hobby folks cost is a consideration but the satisfaction of doing it yourself is a big plus. I could redesign...

Brian: didn't you buy a kiln a couple of years ago? I added the PID control to mine because the original temperature control was just a rheostat and not at all accurate. It controls the temperature very well. I don't know if you are just bored after your surgery but I think that you are...

I built Elmer's geared steam engine several years ago and have since sold it. It is a neat engine but it has an internal gear which he specifies a 72 tooth Boston Gear. It is super expensive. Is there some way to make this gear? The only thing I can think of is to make some kind of a broach and...

OK I finally got this thing to run. Opened up the intake and exhaust ports. Made the cam follower forks wider. Plans call for .130" to run on the .125 cam. opened it up to about .050. Seems to run better at about 5 to 10 PSI than it does at 20> PSI. It certainly is not a powerhouse. Any friction...

Believe me you would not see anything with a photo. This thing is only about 3" and whatever is wrong is happening internally and is not visible. I do have a question for you. You said that you have eliminated all of the automatic features for dimensioning and it works much better. I am not...

Maybe for you it is a few minutes work. For me that would be at least an hours work. I do not work with the program enough to actually become proficient with it. Also because I am old and retired I am easily distracted so I work on a project for a while and get sidetracked with something else.
