Bucyrus Erie Model 22W

The city where I live gets the majority if its water from wells, and the growing population requires more wells. Several years ago the city let a contract to drill a well in the corner of a city park just a little more than a block from our home. I have this problem of being attracted to machinery like iron to a magnet, so I had to go investigate the ruckus. It only took one trip to become acquainted with the owner operator Robert Perry. He worked alone and enjoyed having visitors like myself come every day to check the progress and chat for a while. Not only did I make a good friend, but I received one heck of an education on well drilling.
Then I have this second problem of wanting to build a model of every kind of old machine I see. So I started looking closely at the workings of the machine. Robert could see my interest, and suggested that rather than building a model of the #36-L machine that he was using that I build a model of a Bucyrus Erie #22-W, because he claimed they were the most popular well drilling machines in the world. Robert loaned me some operators manuals and parts books, and furnished me a key to his yard over in Spanish Fork City where he stored his fleet which included three 22-W machines, so that I could go measure and photograph as needed.
About 10 months later, the model was finished. That may sound quick, but you need to know that back then I did not limit myself to 8 hours a day or 5 days per week.

Right and left side views as it looks today.

Here is a view showing it erected in the driveway right after it was completed.

And another closeup looking down into the workings. The model has all the parts and functions of a full size machine. The only difference is that it is equipped with a variable speed electric motor rather than a gasoline engine. It will do everything the full size one will do. It would probably even drill a well, except the drill stem is so light it would be pretty slow going.

Oh, I need to tell you that when building the model I made double of everything and ended up with two models, one of which was given to Robert. Here is a picture of his little rig, set up next to his much bigger Bucyrus Erie #36-L that he was using to drill the well for the city.

A few pointers on the well he drilled: He started with a 30 inch casing and went down as far as he could drive it, then kept stepping down in sizes as he needed too. They stopped just short of 800 feet. It took about two years although that had not originally planned on that much time. Provo sets in the basin of lake Bonneville. An ancient lake at least equal in size to the great lakes today. Where he was drilling was close to the mountain and the material that he was going through was mostly silty stuff that over time, had washed down off the mountain into the lake. One day as I was visiting, he pulled up a soil sample from 300 feet and when he opened the sampler there was a perfect snail shell about as big as your thumb nail, except it was as soft as drywall mud. The formation had water in it, but being so fine it did not flow very fast. About all they could pump was 500 gallons per minute. So he put a 16 inch screen down the hole and started to develop it. The screen was a stainless steel pipe with very narrow slits, that would let silt through but not course sand. He put a rubber head on his drill stem that acted like a piston. It can be seen in the picture with his model. He spent several months pumping that thing up and down in the hole pushing water out and drawing silt in, and then bailing out the silt. This produced a cavern down in the hole, which provided more surface area for water to seep from. In order to keep the cavern from collapsing in he kept dumping a special processed course sand down around the screen. Would you believe three 18 wheel semi truck loads?. When he finished the well would produce 3500 gallons per minute. Just as a point of interest, the city figures they need a capacity of one gallon per minute per household. So that well should take care of 3500 homes.

Everyday a Little More Progress

I'm still chipping away at the model steam shovel. I sure don't do much at a time, but every little thing, no matter how trivial is progress.



Some of the piping and a couple control levers are suspended from the roof, so I have started building a cab framework to hold them. Also some of the boiler fittings need to be coordinated with the roof line, so I'm working on the two together, so everything will fit when completed.


Yesterday My entire efforts in the workshop barely made a teaspoonful. The valve bodies for the try cocks for the boiler.


And they are not much more than half finished. They still need stems and valve handles. Oh well, my hobby is my "pass time" and it sure does!

And here they are.

Spark Plug Boot

This is not my invention, I read about it a number of years ago in some publication, but it is so simple and easy and looks good.
Machine a brass cap to snug fit on the spark plug cap and solder your spark plug wire to it. Slip a small O-ring on the wire, and a larger one on the brass cap near the open end. Plug the opening in the cap and dip the thing in that rubber like compound that you dip plier handles into for grips. You can dip a couple times to build up as desired. Then with a knife trim the hardened dip around the plug and and pull it out, you have your very own custom boot.

Pistol Pete

I need to make an opening statement that I'm not a gun nut. What I enjoy about them is that they are mechanical things, and machining parts for them is not different than machining parts for any other metal project, and I can express myself with a bit of art work.
When our son Mark was in high school he worked part time in a little gun store to earn some spending money, and through that experience he acquired the nick name "Pistol Pete". A name that he quite liked. In fact, at age 50 his wife still calls him "Pete". So a while ago, for a project for me, and a memento for him I built him a muzzle loading pistol. The barrel is a remnant from a rifle barrel. Patterns were carved and castings poured out of aluminum bronze. The butt cap is a casting that looks like the face of his little beagle dog. The hammer spring was hand forged out of a pitch fork tine. It has a carving of a moose, and an antelope, both of which Mark has bagged during his lifetime, plus oak and maple leaves. Although it does not show in very well in the pictures, the barrel is engraved with scroll work and the words "Pistol Pete". Ruby garnets are set in the fore end cap, the dragon's eyes and the beagle dog eyes. Although it is fully functional, it is very doubtful that it will ever be fired. It is a show piece.




When I gave the pistol to Mark I was telling him that the hammer was a "Fire Spitting Dragon". His little daughter Shyrel who was about 6 at the time, put her hands on her hips, looked me straight in the eye, and said "No its not Grandpa, Its a baby dragon and it is sucking on the nipple." Oh well, you cannot fool then all the time, and some you cannot fool any of the time.

Lathe Trade

A few years back when I had to go to work for a living, One of the coworkers named Kip was telling me of going to a yard sale and buying a little metal cutting lathe for $40. He did not know what kind it was, but it sounded intriguing. Kip builds things by welding, but does not have much interest in machining, so I offered to buy it from him to put in my collection. I even got up to where I offered three times what he paid, but it simply was not for sale for money. However he was very willing to trade it for one of my miniature muzzle loading rifles. I don't normally do gun work for people outside my family, but Kip was almost like family and I wanted that lathe, so I agreed.
I failed to take a picture after the rifle was finished, but below is one taken during construction. There is a full size Hawken muzzle loader reproduction that I built for myself leaning against the tool cabinet for size reference. Then a half size one right below it, and the one in the vise under construction is the one that was traded for the lathe.

It took about a hundred hours to build the miniature, because every part has to be hand made from scratch. I finally finished it and delivered it to him, and then he brought the lathe for me the next day, like a mail order bride. That lathe had so much crud on it you could not even tell what it was. But some solvent and a parts washing brush fixed that. I uncovered a decal that said "Craftsman".
It was a model AA109.

Was it a fair trade? You bet! We both got what we wanted. I got more iron, and he might have got more value, but what is a few hours between good friends.
At home Kip had a 4 year old grandson pose with the rifle while they took some pictures and that kid was really "hamming" it up. When the picture taking was finished, Kip went to get the rifle and that was not an option as far as the grandson was concerned. Kip had to pry his fingers off to get it back.
Shortly after I got the AA109 set up on display, my friend George from Brigham City brought me a box of lathe parts that someone had given to him. Apparently someone had taken it apart to paint it and then never reassembled it again. The main parts were there, but so many of the little parts had vanished, like gibs, half nut, handles, etc. etc. that it was no longer serviceable. It was a model 80. Just a newer version of the AA109. Most of the working parts are interchangeable. After sitting in the nurturing atmosphere of my workshop it began to grow those missing parts until it became functional again.



Both lathes are now on display. They would do machining, but not the way my new Jet does, so they can just sit there and amuse our visitors.

Boiler Boring

Several days ago I started work on the boiler for the model steam shovel. It needed to be 5" diameter to be scale size, and I was able to find a piece of 5" seamless tubing down at the plant where I use to work. Real good stuff. Only the wall was so thick it about broke my arm to pick it up. It would probably withstand several thousand pounds per square inch internal pressure which was also a bit more than I needed, so I decided to bore it out until I had a more reasonable wall thickness and get rid of some of the weight. My standard steady rest would not accommodate the 5" diameter so I rigged up a Rube Goldberg type steady rest from some pieces of flat bar stock that was laying around. I did not even cut the pieces to length. For contact supports I used skate board bearings. (Those kids will learn not to leave their skate boards laying around unattended)



The bottom ends of the bars are bolted to a 3/4" plate that is clamped to the bed, but as you can see the upper ends are just clamped together with some sturdy C-clamps. The boring bar was only long enough to reach half way through, and when this picture was taken one end had already been bored out and the boiler tube flipped end for end and a couple passes had been made in the second end. The whole operation went very smoothly from start to finish, and the thing has been tore down and put back on the metals rack.
It is such a simple thing that I hesitate even posting it, but perhaps someone will pick up and idea that they can use sometime.

Buffalo Springfield Steam Roller

Setting on a display pedestal painted to look like the world, In Gibbons and Reed General Contractors yard, right next to the Freeway was a little Buffalo Springfield Steam roller. It would cause awful twisting of the necks of mechanical people like myself as we drove by. How wonderful it would be to have a steam roller to play with, but of course it was not for sale, and besides there was no way that a person like myself would have room for it, or move it to tales to shows, etc. BUT I could certainly handle a baby one. I called the company and talked with Mr. Reed and got permission to come in and take photos and measurements. Several trips were required over a period of time to acquire enough information to put a complete plan on paper.
I might mention that the front roller and water tank were not original. At some time they had been replaced, so I I followed a picture in a book as to what the originals looked like. Also the yellow paint was not the original color.
It took 10 months of construction time to complete the model.

Here are right and left side views.

Perhaps you'd be mused at looking at some close ups.

Here are some loose engine parts.

This is the engine put together.

And the engine installed on the roller.

This is the gear train. I strayed from the original, by installing Bikini type guards over the gears. I just could not stand to hide those little gears with the full covers. Some things need to be seen to be appreciated! Don't you think so?

This is the drivers seat. I never did figure out which was front and back of the machine. I think the steering roller is in front, but that makes the driver facing back. You figure it out!

And here is the whistle. All steam things need a whistle, don't they? The bell is made from an empty 30-06 cartridge case. For a miniature it has a very pleasant sound. I had to design a restriction into it to limit the pressure or else it would be too shrill.
This little roller is not a "loner", It has a twin. Some other fellow; he is listed on this site as "paulj84003" built one too. The models were built simultaneously in our respective workshops, but we shared drawings, materials, patterns, fixtures, etc, which expedited the construction. Perhaps he will post some picture of his baby roller too.

Frisbie Engine

While I was looking through one of those Shire Albums #137, titled Toy Steam Engines, printed in England I noticed a rather simple little engine, that had a unique "patented" valve mechanism. The cylinder is stationary and it has a wobble valve plate actuated by a lever connected to the connecting rod. They were built in Connecticut around 1871. The name Frisbie comes from the inventor. He had invented a number of different toys and things.

It intrigued me enough that I made patterns, and castings and built one. The steam pressure gets up to the cylinder through drilled passages in the support bracket.

Here is a picture of my replica. I have never actually fired it, but I have run it on compressed air and it runs beautifully. Other pictures that I have since seen show an alcohol lamp type burner under the boiler.

After completing the model I found that they also made a walking beam version. The above image was scanned from a full page picture in a book about toys. I have not got around to building one of these yet.

Olds Engine

Here is a picture of a model Olds Engine built from Breisch castings. As models go it is a fairly large model, but a real pleasure to work on. I did not have to use a magnifying glass or tweezers to pick up the parts. It has one of those 10mm Honda spark plugs, and another of those homemade buzz coils for ignition. They really seem reliable for slow speed engines. It must have been a good system, because Ford used them for the model T and the Fordson tractors. When this engine was finished and fueled up, it took off running the very first time it was pulled across compression, and it has started about that way ever since.



Striping seems to add a nice finishing touch to models, and an old draftsman's ruling pen works very well for that job. Do not try to dip the pen in the paint, but rather pick up a drop with a toothpick and place it between the blades and let it run down to the points. You will need to use a straight edge or French curve to guide the pen unless you are much steadier than myself. Be sure to block the guide up so that it does not contact your freshly painted line and smear it, otherwise you might be inclined to use some of those unmentionable words stored in the back of your vocabulary.

Oh, and the "B" on there can also stand for Birk, as well as Breisch

Plowing

I'll post one more topic on model farm type equipment and then I'll get back to more engines and stuff. This model plow very closely resembles the one that my dad used in the 1940s. In fact I even used it a lot. There were no such things as child labor laws on the farm, so as soon as I was old enough to operate the tractor by myself, at about 7 or 8 years old, I was put to work. I certainly did not consider it labor, it was a chance to drive the tractor! All us farm boys took great pride in driving our dad's tractor. Whenever we would get together at school or other places we were always boasting that our dad's tractor, no matter what the make or model, was the best.


The plow is pretty well complete and functional. It has about all the parts of a real plow, except tiny. The beams were made from 1/4" keystock, and then I ran a ball mill down the length to shape them like originals. Of course the wheels are fabricated to look like real ones.
The tractor is just a generic dummy built to display with the plow. The wheels turn and the steering works, but thats it. I picked the rear tires up at a swap meet. They are solid rubber, and have the tractor tread and the Firestone trademark molded in the sides. They had real heavy duty bearings in them so I suspect that they might have once been used on a hand truck or something. The front tires are exhaust pipe hangers. The engine parts was built of square tubing, the grill was cut out of the side of a one pound propane tank, and the fenders were cut out of a pot lid from a second hand store. Tractor parts can come from lots of places.

Russell Grader


We were watching the Antique Road Show on TV and some fellow had brought in a little horse drawn road grader. It had been a salesman's sample of an Adams road grader. I was quite intrigued with it and thought that would be something interesting to build a model of. My dad had an Adams grader to smooth the roads on the farm, but the farm had been sold and besides it was a hundred miles away. I did have a book about Russell Graders, so I picked one of those to model. According to the book their "Highway Patrol No. 2" was their most popular model, although perhaps not their biggest or best. It probably suited more clients needs. There were a couple photographs plus a list of specifications, which was very helpful in getting started sizing it. My model was built 1/10th scale. Same as the hay press and manure spreader.

It was so tiny that I put the lettering on freehand with a little brush. The angle frame was made by splitting 1/16" wall square tubing and then milling the legs of the angle to size. The seat was pounded out on a bench block, and the holes punched with a slotting punch made from tool steel, on the end grain of a scrap of hard wood.
Oh, I also need to mention that Russell was an aggressive company, and kept upgrading, redesigning and experimenting, using tractors etc. for power. This did not go on unnoticed. In 1928 Caterpillar Company acquired the Russell Company. So when you see one of those big old Caterpillar graders going down the road, remember the little horse drawn Russell grader was it's predecessor.

Lathe Trade

One day when I was visiting with my friend George in Brigham City he offered me a box of cast iron stuff because he knew I was a collector of such things. He said he had already discarded most of it, but I could have what was left over. When I got home and sorted it out I determined that it was the clutch pulleys for an old overhead line shaft lathe, his lathe in fact. He had moved the motor down onto the bench with the lathe. What he had discarded were all the hanger bearings, etc. The next time I seen him, I told him that I really appreciated the pulleys, but what I really wanted now, was his lathe. He had already upgraded to a new 13 x 40 Grizzly lathe, so working out a trade was not too difficult. A little more than an equal amount of iron in the form of an old drill grinder and a drill press did the job.



The lathe, by the way was built by Champion Blower and Forge. It looks very much like a South Bend, so that was probably the predecessor of that line. Don't know the date of manufacture, but would suspect it to be 75 to 100 years old. I welded up a stand and painted it flat black to look like the old cast iron stands. For its age it is still in pretty good shape, but of course I only use it for display purposes.



Then looking at pictures in old catalogs I made patterns and cast replica hanger bearings and supported them from a framework near the ceiling. It is nothing like a full length line shaft in a factory, but at least it gives visitors an idea of how things were powered. I have it powered with a 1908, 3/4 hp repulsion-induction motor barely visible in the picture. It is huge, probably as big as a present day 10 hp motor. It has that wonderful old whiney sound, that only old people know about.

Manure Spreader

Mechanical things of all sorts fascinate me. I was born and raised out on a farm. Although seasonal, one of my first paying jobs was working a a steam powered sugar factory. Then I spent over forty years working at a steel fabricating and manufacturing plant as a facilities Engineer, which provided me an opportunity to visit and see many other facilities all over the nation. My eyeballs were exposed to viewing all sorts of mechanical contraptions, and I loved all of them.
I was thinking I'd like to build something that used drive chain. In scale size, I was thinking of using some "ladder chain", even my old Erector Set had a piece of that. Finally I decided on a Manure spreader, a humble but very essential piece of farm equipment. After months of looking I finally located one as a decorator item in a lady's flower bed, that I could get measurements from. It was of the 1930's vintage which would been state of the art about the time I was born.


The second picture shows it well under construction. I tried to follow the construction of the original, right down to each rivet and bolt. There were lots of rivets in this model, a couple hundred of them. the whole frame was riveted together, as well as the wheel lugs and beater parts, etc. For rivets I used snipped off 19 gage wire brads, and set them with my tiny rivet press (third picture)



The picture shows the size of the press. The scrap metal there, has a trial rivet set in it. The angle Iron frame of this model varied from about 1/8" x 1/8" to 1/4" x 1/4" so setting rivets would have nearly impossible with a hammer without mashing everything. It was so easy with the press. The difficult part was that rivets had to be placed in the holes with tiny needle nose pliers, and sometimes the rivet would slip and go flying off in some unknown direction. No need to even try looking for it, just get another one.


The last picture shows the finished spreader. I found the color scheme and brand name in one of Charles Wendel's books. It has turned out to be a real fun model to show. Everyone has some kind of humorous remark to make about it. Like one fellow suggested it be loaded with cinnamon sugar and raisins when making sweet rolls, or shredded cheese when making pizza. Another suggested Bull Durham tobacco because it would look and smell like the real stuff. Another suggest corn flakes because they would be easy to vacuum off the living room floor. One fellow informed me that manure spreaders never came with a warranty. That is one machine that manufactures just would not stand behind. The list goes on and on. Perhaps you will have a comment too.

Steam shovel castings

There are several castings in this little model. Rather than explain, just look at a couple more pictures. I've been making castings for models for about 40 years now, so it is nothing so special, just part of the job.
By the way I been at this model since last June (About 9 months so far)
Birk




Steam shovel close-ups

Ok, here are some more close up pictures. You will note that it is missing some bolts, pins, etc., because it all has to come apart someday for painting.
A question was asked about sealing riveted boilers. Yes, they needed to be sealed with solder.
I should have mentioned that I shear rivets to length, if they are small ones, say 1/8" and under with one of those electrician's crimping tools that have holes to shear threaded screws off. I drilled a couple more holes in it with a carbide drill. For larger rivets I made a shear out of a automobile leaf spring that works the same way as the electrician's tool. Sawing is so slow, and clipping them with diagonal clippers leaves a wedge shape end.
