New Proprietary Coated Heads Show Zero Wear After One Million Parts

The NEW Davenport Proprietary Coated Head shows zero wear after producing one million parts in a test run on a customer’s machines. Now the same extended wear-life found on the Revolutionary HP Revolving Head, is available on Standard 8-SA Heads with standard spindles.

Using a proprietary metallic hard-coating material on the bearing diameter bands, the 8-SA Head has less friction and less wear. This is a proven way to extend the life and accuracy of the Davenport Model B and Davenport HP screw machines. After repeated testing, the hard-coated heads show NO VISIBLE OR MEASURABLE SIGNS OF WEAR!


  • Both bearing diameter bands are covered by a proprietary metallic hard-coating material
  • Hard-coated heads retain oil better and reduce friction during index by over 65%
  • Greatly reduced galling and pick up on the bearing bands due to dissimilar metal interfaces – indexing the revolving head no longer runs a cast iron head on a cast iron bed
  • Extended life and accuracy of the Davenport Model B or Davenport HP Runs:
  • No visible or measurable wear on hard-coated heads after producing over 1 million parts
  • Test machine has NO SIGNS OF WEAR on the scraped bores, with the original oil-distribution scores of the scraping bar still evident on 100% of the bore
  • No burnishing of high spots was evident at any point in the bores
  • The head and machine bed looked like the day they were assembled, and with good spindles, they can make parts as accurately as the first day of operation!
  • Also available as an option on oversize 8-SA spare parts and full revolving head assemblies

Davenport Machine is the only ISO 9001:2000 certified manufacturer of Davenport replacement parts in the world.

Stories of Earl Brinkman: Early Days at Davenport

Chauffeur for Mr. Lewis

As a young man, only in his teens, Dad applied for a job as a chauffeur for a local machine tool dealer named Mr. Lewis. When he hired him, he told Dad, “Let’s go”. Dad climbed behind the wheel and tried to decipher the confusing levers and pedals that lay before him, never having driven a car in his life. Mt. Lewis quickly realized what was going on and asked Dad, “Earl, have you ever driven a car before.” Of course Dad said, “No sir”. So Mr. Lewis said slide over and I’ll show you how. Dad drove Mr. Lewis to the golf course every morning to play nine holes before work. Eventually he became a mechanic for the company which led to the following.

Lewis Machine was a new and used machinery dealer in Milwaukee. One of the lines he represented was Davenport Machine Tool Company, Inc. from Rochester, New York. One day Mr. Davenport was in town making calls on local customers. In the morning Dad was moving a turret lathe out from the corner of the warehouse by himself to prepare it to show to a potential buyer. At noon, when Mr. Lewis and Mr. Davenport returned, the machine was in the middle of the floor, completely disassembled and cleaned up. That evening when they returned, the machine was assembled and running. Mr. Davenport being duly impressed said to Dad that if he was interested in learning the Davenport machine he should write him.

The invitation from Mr. Davenport was immediately followed by a letter from Dad and his travel to Rochester to study the machine. After a few weeks Dad knew he didn’t know enough about the machine to go back to Milwaukee. After a few months Mr. Davenport sent for Dad, who was working in the assembly.

Dad, being a young guy of nineteen at the time, thought he had done something wrong to be summoned by the owner. When he walked into Mr. Davenports office Mr. Davenport asked him, “Earl, is Mr. Lewis paying you while you are here learning the machine?” Dad said, “No sir.” Then Mr. Davenport said, “Did Mr. Lewis pay your transportation to come to study the machine?” Dad again said, “No sir?” Then Mr. Davenport asked, “Is Mr. Lewis paying your support while you are learning the machine?” Once again Dad replied in the negative. After a short pause Mr. Davenport said, “Well then Earl, would you feel free to accept a position with the company?” Dad immediately replied, Yes Sir!” That started a fifty four year career with Davenport that culminated in his being known as “Mr. Davenport” throughout the world.

Davenport Announces New Servo Threading Attachment

Davenport Machine has developed a new Servo Threading Attachment that will retrofit to existing Model B multi-spindle automatic screw machines.

The new attachment eliminates clutches and the gears associated with mechanical threading attachments. It also provides users with unlimited programmable spindle speeds within the range of 0-6000 RPM. The new attachment eliminates gear changes and clutch adjustments that create maintenance downtime thus increasing machine operating efficiency.

Also, the ability to provide infinitely variable spindle speeds creates a better quality thread and lengthens tool life. The correct spindle speed is now programmable rather than being dependent on specific gear ratios that may not include the optimum speed for the application.

The new Servo Threading Attachment is standard equipment on Davenport HP machines.

Back From The Brink – From Canadian Industrial Publishing

A well-known and well-respected brand from the past has recently made a comeback thanks to industry veteran Robert Brinkman, who acquired the assets of Davenport Machine last year with a clear mission in mind: to win back Davenport customers.

A successful showing at the recent Westec trade show has Brinkman enthusiastic about the prospects of rebuilding the Davenport name and its successful line of screw machines. The company’s latest contribution to the screw machine market is the Davenport HP, a machine with simple, PLC-based controls and multiple servo drives that have eliminated 150 parts from the original, mechanical version Model B machine.

The new control system means that operators can concentrate on producing parts, rather than fine-tuning adjustments. This was done in order to reduce set-up times, increase the machine’s flexibility and increase the already high production rates.

“There was great interest in our machines at Westec, and we have several promising orders,” said Brinkman, president and CEO of Davenport Machine, Inc. “And not only for rebuilds – the rebuilding of Model Bs and converting them to Servos – but also new machines.”

Full servo upgrade packages are available that will convert existing machines into Davenport HP units, allowing them to incorporate many of the same productivity gains available on new machines. It was in this market, along with the existing Davenport parts business, that Brinkman still saw value.

At a time when Davenport was struggling with bankruptcy, he still saw a company that was worth something… but at the right price. “I grew up in the industry,” said Brinkman, “and my father spent 54 years at Davenport. What we need to do is provide the customer with great service and fairly priced, quality parts – it’s not rocket science, it’s just being a reliable and appreciative supplier.”

It’s this type of attitude that Brinkman hopes will re-attract Davenport’s old customer base and bring the Davenport name back into prominence in the machine industry. “There is a great deal of history in my family with Davenport. So there will be a lot of satisfaction in bringing it back,” he said.

Stories of Earl Brinkman: Trade Secrets Revealed

Ware Brothers vs. Chicago Roller Skate

Dad always said, “Keep your mouth shut.” Here is one of the reasons. Dad used to sell Davenports to either Chicago Roller Skate Company or Ware Brothers, or both-Can’t remember.

In any event, roller skate wheels used to be made out of hard wood doweling. It came is short lengths and was relatively expensive. The wheels were made by turning the doweling in a lathe. Drilling, counter boring, turning the OD and cutting off. One of the men in the shop came up with the idea that instead of turning the wheels from doweling, maybe they could be finished from stamped blanks made from hardwood planks. The owner agreed to let him try it and very quickly the cost of wheels dropped by ninety percent. Of course they only cut the price by ten percent and rapidly cornered the market on roller skate wheels.

Unfortunately, this only lasted a short time and soon the other company met the price and lowered it a little. The ensuing price war resulted in the cost of roller skate wheels plummeting to ten percent of the former cost. The owner realized that someone had let the cat out of the bag but couldn’t imagine who.

Several months later the insurance safety inspector, a rather dim witted man, came through the plant on his annual inspection tour. He noticed the punch presses stamping out the blank wheels and said to the Owner, “I see you are still stamping out wheel blanks.” When I inspected the other plant in town I was surprised to see that they were still turning from hardwood doweling and asked them why they weren’t stamping.

Well, Dad said they guy was lucky the plant was only one story or else he surely would have been killed when the owner threw him out the window!

Anderson Fittings Taps Davenport for Single-Operation Solution

Anderson Fittings, Inc., opened its doors to manufacture brass fittings, valves, and accessories for a variety of industries over 50 years ago in 1947.

Since then, the company has steadily grown in its Chicago-area location, expanding its product line to include air brake and pneumatic fittings, and now employs over 200 people. “Providing practical and complete fitting and valve solutions with rigorous quality standards-that’s how we got to where we are today,” says Dan Crapia, Director of Technical Services.

“It all comes down to delivering quality product based on customer budget and scheduling needs.”

As with many manufacturers today, streamlining production to stay competitive in the global market has become increasingly important at Anderson Fittings. The company had already introduced concepts such as machine cells to their floor, where production of a particular part never leaves a dedicated area of machines, to aid in this goal, but new solutions were still being sought.

The company had already introduced concepts such as machine cells to their floor, where production of a particular part never leaves a dedicated area of machines, to aid in this goal, but new solutions were still being sought.

Deciding to contact Davenport Machine about eliminating the second-operation tapping for this part was an easy decision.

“We have 22 Davenport machines currently in our shop, two of them being Davenport HPs, so the Davenport name was already in our minds,” Crapia explains. “In fact, we had purchased a used Davenport HP for short, complex runs, and we were very pleased with the machine. Since we knew this part was definitely the right size to fit the Davenport HP’s capability, we decided to ask Davenport about this challenge first. As it happens, we never needed to ask anyone else.”

After communicating their need directly to Davenport, blueprints for the double-ended fitting were sent for evaluation to Donna Foley, Sales Engineer, and Doug Larson, Applications Engineer. Larson quickly began to assess the plans.

Davenport Machine Benefits from Increase in Aerospace Industry

For over 100 years, American Manufacturing has understood that the most efficient and cost effective way to manufacture large volumes of turned machine parts is on a Davenport. The American aerospace industry has always understood that the best way to get flawless quality and a repeatable process for manufacturing aerospace fasteners is on a Davenport. Like many industries, aerospace companies have been through tough times over the last four years, but appear to be recovering nicely and have expanded their use of Davenport Machines.

The Davenport Model B has always been the machine of choice for manufacturing aerospace collars and shear nuts. The Model B has been utilized since the beginning of commercial flight to make these crucial components. With the advent of the Davenport HP making these complicated little products was made much easier. The high precision head in every Davenport HP makes holding tighter tolerances a breeze and with the electronic controls, programs can be stored directly in the machine allowing multiple operators to make the same part easily. Davenport is currently experiencing a resurgence of both the Model B and the Davenport HP within manufacturing companies that make aerospace fasteners of all kinds.

The aerospace companies we have spoken with appreciate the choices that they have with Davenport. A new Davenport HP, new Davenport Model B or an existing machine fitted with a new HP head appear to be the most popular choices among these companies. Many manufacturing managers find that simply retro-fitting an older Model B with a new HP head allows them to run parts on the Davenport that they used to have to run on much more expensive machines with slower cycle times. The fact that Davenport is capable of building new machines, re-building existing machines or re-fitting an existing machine with an HP head allows flexibility when planning budgets. Even coming out of the recession many companies are hesitant to budget large capital projects and the flexibility that Davenport provides means they can spend what they want, when they are ready and still achieve significant efficiency increases.

Stories of Earl Brinkman: Stories from the Plant

Coolant Blues

There are many stories of things going wrong in the plant. Most were just human error or ignorance and I guess you could say this incident is both. The men in the turret lath department were plagued by dermatitis on a regular basis. The machines coolant sumps would be pumped out and cleaned and the problem would go away for a while only to return. One night, Dad was walking to his car which was always parked in the garage by the heat treat department. He walked around the corner from his office and saw one of the night shift operators urinating in the sump of the turret lathe. The guy was to lazy to walk around the corner to the men’s room. Problem solved!

Stripped Naked

You would think safety would be a common sense thing. But as they say, if it’s common sense, why is it so uncommon? Dad was walking through the plant one day and happened to see an operator duck under the bar stock of a turret lathe while the machine was running. (Could it have been the same guy from the above?) Anyway, Dad lectured him on how dangerous this was as it was before OSHA, w-a-a-ay before I suspect, and the bar ran on a support without a tube around it. Of course the guy didn’t listen and sure enough one day he ducked under again. Only this time he wasn’t so lucky. The revolving bar stock caught him by the collar and he went around the bar about a dozen times until all his clothes were wrapped around the bar. It spit him out and he slid across the floor without a stitch of clothes left on.. Needless to say, he never did that again!

Setting the Blocks

Dad was always a stickler for quality although it was way before SPC, Six Sigma or any of the modern techniques of quality control. The company started to get complaints about the machine not repeating spindle to spindle so he went down to the assembly to investigate. He asked the man setting the blocks to show him how he was doing it which he did. There was an indicator on a fixture but Dad could see that there was room for error. He designed a better fixture that would eliminate any chance for error and instructed the assembler how to use it. The repeatability problem went away, but only for a while. They soon started getting complaints again and the servicemen on the road confirmed that the problem was back. Dad immediately went down to the assembly to check on the fixture he had designed and asked the assembler whether he was using it or not. The assembler said, “I’ve been doing this for twenty years, I ought to know how to do it by now.” Now the old timers will remember my father as a quiet spoken man who rarely raised his voice to an employee. (Customers were another matter.) But, when he heard this he said loud enough to be heard across the plant, “And you’ve been doing it WRONG for twenty years, now use the Goddamn fixture.” The problem never returned.

Visitors from Foreign Lands

Dad’s reputation was world renowned and he enjoyed the international aspect of selling machines all over the world. Whenever foreign visitors would visit Davenport he would always have them out to the farm on Buffalo Road for lunch. Mom would make Reuben sandwiches or something fresh from the garden. Once we had a man over from Scotland. At that time my sister had many horses and right after lunch she came running into the house to tell Dad that there were two fox out in the field behind the barn. Fox were never welcome around the farm as they not only were a menace to the chickens, but they occasionally carried Rabies. Dad grabbed his .257 Roberts rifle and we all headed for the barn. From the hay loft above there was a perfect view of the field and the two fox. We all waited and waited for Dad to shoot and finally whispered up to him. “Why don’t you shoot?” to which he replied “Shut up!” In a few minutes he did indeed shoot and killed both fox with one shot. The Scotsman said, “Man, you’re lucky.” To which Dad replied “I’d be on that shot any day of the week!” Then the Scotsman said, “No, I don’t mean that, I mean you’re lucky that you had three witnesses!”


Mom and Dad always entertained a lot and they never catered anything, always doing all the work themselves. One of the annual events was a clambake that grew and grew until there were over a hundred people coming to the farm. The preparation took several days and we scrummed clams for hours the night before and soaked them in corn meal to get the grit out. This was always a fun affair until the final year. Dad was hustling through the house making sure everyone was taken care of when a woman he didn’t even know said, “Hey you, get me some more butter.” Well, Dad figured that if there were people there that didn’t even know that he was the host then it was time to call it quits. That was the last clambake.

Stories of Earl Brinkman: Growing Up Poor

Hiking to the Blueberry Ledges

As one of fourteen kids Dad and his siblings were always put to work in one way or another. Grandma Brinkman was a great cook and had many skills that helped keep the family fed. She would send the boys off to the blueberry ledges with homemade back packs made from old packing crates and strapping. It was an overnight trip because the ledges were several hours hike away. They would arrive, pick, make a camp fire and some shelter then hike back the next morning. Grandma would make preserves that would last through the winter. Yum!

Raising money through ingenuity. The old plant in Milwaukee.

The boys were always looking for ways to make money. After the family moved to Milwaukee from the U.P. there were many opportunities, some quite ingenious. There was an old factory not far from home that had been torn down, possibly a car plant. The boys in the neighborhood used to play ball on the empty lot, almost two square blocks. Two of the brothers discovered that every twenty feet there was a footer for the support columns. This footer had a big piece of plate steel on top.

But it was heavy! The problem was how to get the steel to the junk dealer, having no car or truck they could use. Well, the junk man had a push cart which was usual way back then. He left it every night, outside the gate to the yard, chained to the fence. The boys figured they could “borrow” it which is what they did after cutting one of the links. Every night they would go to the old plant site and collect as much steel as they could manage in the cart. Every morning, stacked up neatly at the gate was a pile of steel plate. This went on for several weeks until they had all the steel they could find out of the lot. They took their girlfriends out for dinner with the money. The Junk man was never the wiser.

Ball Bearings and Slingshots

While growing up in the upper peninsula there never was very much money, but there was plenty of game. The partridge would sit on the back fence behind the house. A shotgun shell was a nickel which was a lot of money back then. So the boys took apart old ball bearings and used the balls for ammunition in homemade slingshots. From what Dad said they got pretty good at putting a grouse dinner together. Also rabbits, squirrels and whatever else Grandma could cook up. When hunting season came around, (and sometimes when it didn’t come around), the rifles would come out and there was venison to smoke, salt down or make jerky out of. More hunting later.

Grandpa Brinkman and the Bread Crumbs

With so many mouths to feed Grandma Brinkman would bake bread almost every day. This was the crusty home baked kind that made a lot of crumbs when you ate it. Well, the family ate at a long wooden table in the kitchen. After dinner Grandpa Brinkman would very carefully brush all the bread crumbs together into a neat pile. He would then brush them, again very carefully, into the palm of his hand. Then without even batting an eye he would turn and brush the crumbs from his hands onto the floor.
