Ha, ha! This is great… and I'd call it "running a locomotive!" It is only through challenging ourselves that we truly are rewarded. Taking the easy way is… well too easy.Bob D. wrote:I have a 3/4" Juliet II with Baker gear. This was my first loco and I learned to operate with it. I do not agree with Bill as to it's steaming ability. Mine steams very well and I have continuously steamed it using hard coal until I was tuckered out and needed a break. Like any small firebox you have to pay attention and there is not much room for error. I did make new grates for it and a deeper ashpan that allows pulling the grate from the rear. It takes a moment to drop the fire out. I struggled with soft coal. I have experimented with mixes and sizes. I have best success with rice sized anthracite. Stoke thin, fairly often, pay attention to blower use. I rarely poke the fire. This is key to hard coal. Pay heed to tossing the coal in. The small coal size will lift into the tubes. It has tremendous draft. Barely crack the blower at rest to reduce cold air when you open the firebox and not pull coal. Dont stoke when pulling hard. Plan when you add water! If you let the hard coal fire get to low use a little soft to perk it up. No clumping with the hard coal, and burns clean..

Re: 3/4" scale Juliet and CNO&TP Ms-4
Exactly Bob! This is why my dad wants me to build and complete this before my Ms-4! He says that even though I have experience firing his bantam cock, I cant say I know how to fire a locomotive until I spend an hour firing just to get 15-20 minutes of fun or do it on the real thing! He has had experience with both (he fired for Strasburg during the summer of 86 and he used to own a small freelanced 3/4" atlantic). Sticking on the topic of combustion, when my dad bought the locomotive he received a pair of tig welded stainless steel grates. What is the opinion on them? Should we forget about them and go to cast iron? At this point I might as well also make an update. We both finished making two of the three check valves recently. We also completed some parts for the weighbar shaft and I finished making the lid for the lubricator. I cant figure out if I want to put it on a hinge or not!
Back to the shop!

Re: 3/4" scale Juliet and CNO&TP Ms-4
Its been a while since I posted any updates but here we go! After a considerable amount of time was spent studying and reading up on how frames were built, I have finally completed a large section of the frame! I guess this just shows what you can do with about 24 hrs. of solid work time at my skill level! I'm very proud of this, as I have had a couple of failed attempts on some of the frame parts in the past which led to lots of frustration!

Re: 3/4" scale Juliet and CNO&TP Ms-4
Hey everyone! It has been a while since I have updated everyone! About two weeks ago I decided I should do some major cad work for the Juliet so I got right to it! So far i have competed the valve gear, wheels, frame, and the tender. I plan to get the boiler done soon and follow up with the cab, cylinders and other various bits of plate work. For two weeks of work I am really proud! Now if I could only get out in the shop and build this locomotive that fast!
Cheers!
Cheers!

Re: 3/4" scale Juliet and CNO&TP Ms-4
Also worth mentioning is that I have completed the basic outline of the cylinders along with the piston sleves.

Re: 3/4" scale Juliet and CNO&TP Ms-4
Nice CAD work Stuie. Will you be having castings made for the cylinders?
Re: 3/4" scale Juliet and CNO&TP Ms-4
Thanks SilverSanJaun! Right now I am not sure. As I see it there are three ways I can do the cylinders. The first option would be to CNC machine them out of a large chunk of steel or cast iron. The second option is to make a pattern out of wood also made with a CNC milling machine. But the final option (which seems to be the one I am leaning towards) is to have a firm make two lost wax patterns and have them cast in bronze? I like this option because from what I have been told so far this would allow me to core out all the steam passages instead of having to drill them out. On that note what are the options of metals for casting with lost wax?

Re: 3/4" scale Juliet and CNO&TP Ms-4
Another technique is lost foam. Try a web search, there should be a lot of information out there and it's frequently used in home foundries.
Re: 3/4" scale Juliet and CNO&TP Ms-4
Wow! This looks like an interesting and extremely cheep method! Are there any commercial foundries that offer this method to the our kind? One example I just found of this method is from this fellow:
http://www.foundry.ray-vin.com/woodson/47/lostfoam.htm .
If you look at the bottom of the page, the casting he wanted to produce came out with nice results after cleaning up (hopefully a commercial foundry can produce a cleaner casting!). Could this method also be used for casting a one piece frame?

Re: 3/4" scale Juliet and CNO&TP Ms-4
A disclaimer, I haven't done this type of casting yet but have read a lot about it. The owner of the web site you found is/was active in hobby casting email groups and has posted a lot of helpful information. Here is a site that I found several years ago that gives some ideas.
http://www.buildyouridea.com/foundry/lo ... howto.html.
You can also find some videos on Utube.
I understand that a lot of car parts (intake and exhaust manifolds, for example) use this process, but blow styrene beads into a metal mould and then expand them with steam. That's the same way a cheap ice chest is made. It gives a nice finish. A close look at some car castings will reveal a slightly mottled finish similar to an ice chest. A challange with blue foam is that the castings will pick up the finish of the foam, i.e., the bubble holes. Some people use tape to give a smooth finish. The key is that whatever you use needs to burn away when you pour in the molten metal.
I suppose you could cast a one piece frame, but I suspect that you could run into problems with it warping as it cools. In the casting groups a comment is often made, "Give it a try and let us know about your results."

Re: 3/4" scale Juliet and CNO&TP Ms-4
Hi everyone! Time for another CAD update! It has seemed like it has taken forever but I am almost done drawing parts for the smoke box of the Ms-4. 2 days of solid work yet I started some of the parts around half a year ago! Funny how much my cad skills have improved just in this past month! Even then though, I still have quite a bit to do to the smoke box! I still have to; draw the builders plates, super heater plates, smoke box clean out, piping for the Elesco, the Wimble smoke duct, running boards, the blast nozzle, and the smoke box pole supports. Sounds like a lot, right!? Alot goes into building a detailed model! One thing that made what I have done take so long was re-drawing the Elesco feed water heater, number plate, and smoke box front. I am so much happier with the re drawn number plate! I was also happy to finally get a chance to work out in the shop! I started building parts for our fourth ridding car (to the same design as a previous one). Keep on steaming everyone!
