you might wanna polish up the cylinder casting a bit... They din't used to be THAT rough.
Well stated!

I dont know why they made it that way. I guess a light file to smotth it out or sand paper?
or a small grinding wheel on your Dremel would make quick work of that followed by the file.

My guess is they went to a coarser (cheaper) sand for casting. Either that or they quit cleaning them up any more than absolutely necessary to machine.

But then, I only ever handled about 30-40 of them when I was in biz (Both the Model VI and Heritage)… so that was really too small a volume to be a representative sample, either

More progress today. I put the pins in the main frame to hold the fuel cup and then I added a rusted metal plate on the bottom to protect the wood and add some detail.

fuel cup and steam lines installed.

I wrapped the boiler and added the wood siding and hooked up the steam lines.

Next I have to add the fuel bunker and then do te roof. Last step will be stain and test run.

Pretty cool. Is it pellet fueled?

Shawn,
Thanks for posting all the pics of this build. I’ve been tempted to do a BAGRS. Can’t wait to hear and see how it turns out.
Dave

Jon it runs off sterno fuel. At some point I might convert it to butan.

Dave its an easy project and fun. You can do alot with it. Im in the process of adding a roof and sides to it. Should have pictures up tonight. Im also changing the boiler some. The plans say to wrap the brass jacket around the boiler. A friend of mine found that if you leave some space between the boiler and the jacket it performs about 20% better. The flame not only heats the bottom of the boiler but the sides as well. It gives it better steam. I just order more brass sheet so I can make the wrap a little wider.

Since my last update I completed the bunker and the roof. At first I was going to keep it opened like the plans have but after thinking about it I decided a roof would really look good. Plus the KMRR can see all types of weather. The guys needed some protection. The roof is removable that way I can get the boiler out and refuel. he roof is an actuall metal roof I got from an barn localy. (Same one used on my Class A Climax).

Next step is to add some railing to the front and sides. Then I hope to get it stained and add the details - link and pin couplers, pole pockets, rivets, wood load and a bunch of other tools and junk :slight_smile: Then it will be time to fire it up.

EXCELLENT! Now fix that cold solder joint …

I did fix it. Thats the best its going to get. I s u c k at soldering :slight_smile: Its not going anywhere. I pulled on it and it did not move.

My project engine is almost done. I got the wood stained using walnut. (its a little darker then wanted) I added some details to the inside and out. I did attempt a test run yesterday but it was 35 degrees and did not run. A friend of mine has an engine like this that had the same issue. With some experimenting he was able to improve the performance of the engine by almost 50%. His engine would barley work on flat surface. The trick was to create a gap between the boiler and the outside wrap. This allows the sterno flame to heat the sides as well as the bottom. giving it more heat and more steam pressure. He test ran his on my layout in the same temps and it ran very well (see video in Live steam thread) I did the same to mine. A campbells soup can was used for the outside wrap on the boiler. It is more sturdy and creates the gap needed. I also secured the boiler to the can so it can be removed as one unit when filling the sterno. I hope to test run it today and then add wood siding to the outside boiler wrap. boiler with soup can as wrap.

I think I’d lag that…

I did a test run on my garage floor (with a slope) and it ran great. The gap proved to make a hudge difference.

Looks good Shawn…:slight_smile:

:cool:

So have you figured out the total cost of the build?
Ralph

Pretty neat, Shawn. I like that your first figure got a position of honor. :wink:

That is so cool!!! I love the exhaust noise :smiley: :smiley: :smiley:

Your videos really have me interested in this. I’ve been searching around but I can’t figure out where you bought the boiler and engine kit. Most of my search results point me to Sulphur Springs Steam Models’ “KIT-BPE” which is a dead end (out of business ?).

Care to post some links ?

Thanks guys. Ralph Im not sure total cost but I want to build another one with a different body. Should cost a lot less now that I know how to build it. I think I have a new faverite engine. Is so easy and fast to get it up and running.

Too cool! I’ve never heard a live steamer that sounded like that before. It sounded more like a small gasoline engine.
