Steeple Engine

Near the end of October a model of a Steeple Engine was completed. The plan was acquired out of the book titled Historic Engines Worth Modeling, by Anthony Mount, an Englishman. The reason for picking this one was that it had a different kind of connecting rod than and that I have built so far. The design provides for a shorter engine than the usual cross head arrangement. The author stated that it was designed as a marine engine, however the only ones ever built were used on land. After studying the plans, I determined that by changing the plan slightly, all I needed to make was a steeple pattern. For all the rest I was able to use existing patterns that I had made for other models. As can be seen in the video it is a smooth running engine.

Fancy Calipers


Have you ever wondered just how much some people have between the ears? Well, with my new fancy calipers it is not difficult to measure.
In my case, if you are wondering, it turned out to be mostly just space!

Treadle power wood turning lathe


On September 28 2009 I completed the construction of a 1/12 scale model of a wood turning lathe built from a kit P M Research castings given to me by my friend Paul Kuhni. Paul is 87 and reached a point in life where he just cannot tolerate standing at his lathe anymore. Although in the past he has built many marvelous models.
This is the smallest scale that I have worked to, and there were some pretty small parts, bit I managed just fine.
Normally I do not work with kits, as I prefer to scratch build things, but I guess there are exceptions to all rules.

Hay Fork




In 1986 a small building in the shape of an old gambrel roof barn was built in the back yard for storage and display of models and collected things. This was a common shape of a barn used a century ago to store hay. Although this barn will never be used to store hay, I thought that it would be neat to have a miniature Jackson type hay fork hanging from a trolley under the gable end like there would have been on the original barns, used to hoist loose hay up off the wagons through a big door and into the barn.
Last weekend that desire was fulfilled when I got a miniature fork hung up. The use of this type of hay handling was discontinued about 60 years ago when farmers switched over from putting hay up loose to bailing it.

Panther Pup Gasoline Engine



Last Friday, August 21st, I completed another little engine to put on display. It is called a Panther Pup. It is fully functional four cylinder engine, although not a scale model of of any particular prototype. Just another fun little thing to build.

Pedal Grinder

A hundred years ago very worthwhile piece of equipment for a farmer to own was a pedal grinder. It could be use to sharpen everything needing sharpening from sickle blades to butcher knives. When my grandfather Sorenson passed away, I was fortunate enough to inherit his grinder. He use to keep it out in the yard under the apple tree, and all us kids use to take turns pedaling it. It seemed worthy to build a model of, and so just yesterday I completed a 1/8th scale model of it.

Wooden Lock

A couple weeks ago I completed a working lock, built entirely out of wood and glue, for no reason other than just doing it.

Fill In Engine

I had a desire for some kind of different project, and I happened across a web site in England that had instructions for building a little hand cranked box organ. After watching and listening to a number of videos of various ones playing, I placed an order for a set of instructions. But as anyone knows who has ordered anything from across the ocean, it takes time to get here. So while I was waiting I put together this little vertical engine. It did not take much because I was able to use a left over steam cylinder from the steam shovel and the flywheel is a spare belt pulley from the sawmill. It is intriguing, because it has rather different straight line motion linkage that eliminates the need for a cross head guide. The timing was perfect, I completed it march 4th just as my package from England arrived.
The organ was finished about the first of May, but that is another story, and hopefully a video of it will get posted one of these days.

"Fancy Calipers"

One day while looking through an 1897 issue of the Sears Roebuck catalog I ran across a listing for some fancy calipers. They looked pretty handy and the price seemed very reasonable at 8 cents, but Sears, for some reason would not honor the order. Perhaps that catalog was too far out of date. Rather than go without I proceeded to make a pair of my own. I finished them February 22, and I was pleasantly surprised how well they work. Those "old timers" knew what they were doing!

Tool Post Grinder


When building the Gator gun in January I took an old 3/8" worn reamer and ground it down to .360 diameter so I could ream the barrel to 36 caliber. To grind it down I rigged a die grinder to the lathe tool post. It got the job done, but the setup was a little less than satisfactory, so that prompted building a solid tool post grinder of my own design. It was constructed almost entirely of on hand materials, except I did salvage a motor and speed control from a little Harbor Freight grinder. It was completed February 4th.

January was a busy month




After being under construction for 10 weeks, on January 9th 2009, a half scale model of a Winchester Model 1892 was completed. It is fully functional, just like a full sized one, except it cannot be shot because there are no bullets commercially available that will work in it. This is the same model as so often was used in John Wayne and Chuck Connors movies.






On January 21 a rather whimsical under hammer muzzle loading pistol was completed. I call it my Gator Gun, and by golly it has proved to be pretty effective. I have not seen a single Gator in the whole county since it was finished






The month was finished up on the 29th of January by completing a mini .22 caliber revolver. It is fully functional, but it was decommissioned so that it will not shoot bullets. I did not want to take a chance of someone getting hurt with it.

Bimba Too



After building so many engines a person starts to look for something different and unusual. A geared engine seemed to fit the bill. I have only seen one actual model, plus pictures of a couple others. I understand that they were patented by a fellow named Murray in 1908, but I have no knowledge if they were ever manufactured.
The engine employs a planetary gearing system. A point on the pitch line of the small hear generates a perfectly straight line from side to side, this eliminating the need for a cross head and connecting rod. The piston rod connects directly at that point.
This is just one of several model engines that I have built using surplus Bimba Brand pneumatic cylinders, and that is where the name came from. To add interest, it is equipped with a chain driven rotary valve and painted gaudy contrasting colors. Hope you like it.

Watch it in Action.

Paddle Wheel Engine




The reason for building this model is that it has a valve operating mechanism that is a little different than the usual for a steam engine. The cam is forward, operated from linkages fastened to the connecting rod which keeps it out of the splash area of the wheel. Also it incorporates a triangular shaped cam, that provides a rather quick motion to the valve at each end of the stroke. Another peculiar thing about the cam is that it has such a shape that it maintains contact with both sides of the cam follower at all times.
The first 2 pictures show the cams in the process of being machined. The third picture is the finished cams in their followers prior to installation. The forth picture shows the finished model. This is not a scale model of an actual engine, it is just to demonstrate the valve motion.


And here is a little video of it running

Oil Field Pump Video

Oil Field Pump


In this day of high energy costs, I thought it no more that appropriate for me to build an oil field pump, and pump out old cesspools and convert the contents to racing and jet engine fuel. What do you think of that idea?

South Facing Chariot


This afternoon I finished the little Chinese Chariot and everything works just beautiful, so smooth and easy. Just not very accurately. If it headed down a fairly straight road that turned only slightly right and left, it would maintain an accurate pointing of south. But when I designed the gear train I had my brain turned off, and put a 3 to 1 reduction in the gear train thinking they would not have to turn so fast, and that ratio fit real good. Therefore the little pointing man only compensates 1/3rd as much as he should. If the Chariot makes a complete 360 degree turn around, he only turns 120 degrees, so the Chariot would have to turn three complete turns to get him pointing south again. Talk about confusion!
Anyway it makes a good static display and all the principal parts are there. If I wanted it to work accurately, I suppose I could put some 1/3 size wheels on it, but then it would look pretty funny, and probably high center on a rock.
By the way the pointer man is a genuine Chinaman. It says "Made in China" on the bottom of one foot.

Here are some pictures of the build.

Ride in the Wind

A long time ago, somewhere around 500 years, some guy by the name of Leonardo was inventing all sorts of unheard of (at that time) things. In his illustrations he used peg toothed gears. They looked so intriguing, and I've wanted to try building some for as long time. I finally got around to doing it a couple weeks ago. For the body I used 3/8" aluminum, and in one I put 1/4" brass pegs and in the other stainless. Dissimilar metals usually wear better. Shown below are the results.

As with all new things, there are things to be learned, and I learned they need to be properly meshed. In some positions they would hardly run against each other, and in other positions they ran almost as smooth as machine cut gears.
The final use for the gears was in another wind sculpture for the yard to amuse people, as can be seen below.


It is simply an assemblage of used parts, painted some gaudy colors. The rotor turns a shaft that extends down and operates the peg gears, that in turn operate the pedals. The head is fastened to the shaft so it turns with the rotor, and it has a face on both sides so it does a lot of looking around. It is not very normal, but then not much else around here is either, so what the heck.

Birk BBQ

A few weeks ago I put up a post about casting aluminum with Birk. Well, he fired up the furnace once again, but for a totally different purpose. Birk heard that one of my 5 year old sons "fun" ideas for summer was to have the whole family visit Birk. Sounds fun to me. So, Birk thought he would invite us over for a little BBQ. He told Max, my son, that he could cook them on the furnace. Max was thrilled and said we could cast stuff and cook hot dogs at the same time. Here are some photos of the fun. The forge was a little hot at first. The dogs were cooking fast-- almost like putting them into a jet engine, but he dialed back the heat and it worked great. If you're looking for a new use for your furnace, I highly recomend it. Maybe next time we'll do rotisserie chicken on the lathe.

Fathers Day

Here it is Father's Day again. Perhaps You would like to see a picture of my Father's Day Fishing Pole?

It was stuck on the side of the barn, and before long a flying fish got hooked. Now that might sound like a "fish story" but here is a picture to prove it!

All you fathers and prospective fathers have a good Father's Day, OK.
