Today’s Machining Centers Offer More Bang for the Buck
More bang for the buck. That’s what many machine shop owners say they’re looking for when considering a major equipment purchase. Because today’s machine shops are fewer in number and often smaller, it’s important for them to have as much capability as possible in every piece of equipment to maximize the return on investment, utilization
Valve Guide and Seat Equipment Options
For many engine builders the bread and butter business is in cylinder head work. In fact, according to our 2005 Machine Shop Market Profile (also available at www.engine-builder.com) 41 percent of gas and 54 percent of diesel engine builders’ business comes from servicing cylinder heads. And one of the most important aspects of doing this
Connecting Rod Reconditioning: More to it than you might think
The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on
Engine Boring and Honing Equipment
Cylinder boring and honing is the heart of most engine builders’ operations. The equipment you use will have a lasting effect on the quality of the product your shop sends out the door on a day-by-day basis. While equipment varies from manufacturer to manufacturer, so too do your needs for a specific type of machine.
New Technology:Advances in Engine Building Equipment
How has racing changed your engine building business? No, it’s not a hypothetical, industry-generic question; in this case, it’s directed at every reader of this magazine. A strange question? It may seem to be. If you race – or build motors for racers – it’s probably an easy one to answer. But if you stay
Guide and Seat Equipment
Cylinder head work has been and should continue to be a profit center for engine builders. Heads almost always require guide and seat work to restore compression and oil control. This includes drilling, reaming and replacing valve guides, removing worn, loose or damaged valve seats, cutting new seat counterbores, and machining valve seats. For performance
Surfacing Equipment For Today’s Engines
The surfacing needs of today’s engines are as complex as the engines themselves. Multi-valve aluminum cylinder heads on cast iron blocks are a tough combination to seal because of the difference in expansion rates between the two metals. If the surface finishes on the head and block are too rough, lateral shearing forces which occur
Align Yourself
The crankshaft main bores are the foundation of every engine block. The alignment of the main bores is important because their position establishes the centerline of the crankshaft and how the crank aligns with the cylinders, deck surfaces and camshaft. Misalignment in the main bores can cause binding and premature main bearing wear. Misalignment occurs
Dodge City’s Finest; Harry’s Machine Works
No history of the American West would be complete without extensive recollections of Dodge City, KS. Formed as a convenient railroad stop to serve the new Atchison, Topeka and Santa Fe railroad, Dodge City offered something for everyone. That is, if your tastes ran to buffalo hunting, gambling or gunfighting. In its early days, Dodge
The Smooth Science of Cylinder Honing
The basics of honing cylinder blocks hasn’t changed much in recent years, but what has changed are the type of abrasives being used by many engine builders. Silicon carbide and aluminum oxide honing stones of various grits have long been used in power honing machines and portable hones to finish cylinder bores. These types

He is the incoming chairman of AERA’s Vanguard committee, the group providing leadership opportunities to AERA members under the age of 40. Hartmann, 31, has been with the company since high school in the 1980s, beginning full-time employment
Engine Cylinder Bore Surface Finishes
What’s the best type of cylinder bore finish for today’s engines? Most would say it’s a finish that allows the rings to seat quickly and completely so the engine doesn’t use oil. For many applications, that may mean a plateau finish. The surface finish must also meet the piston ring manufacturer’s specifications and have the
1999 Machine Shop Of The Year Award Winner: Metric Automotive Engineering Ltd
Each year, the staff at Automotive Rebuilder magazine recognizes one machine shop that displays business practices that go above and beyond the norm. This year, along with input from the Engine Rebuilders Association (AERA), we have selected Metric Automotive Engineering (Pty) Ltd., from Germiston South, Republic of South Africa. Metric was chosen from numerous entries
Cylinder Bore Honing: Main Objective When Refinishing The Cylinders
When an engine is rebuilt, the cylinders usuallyneed attention. Wear tends to create taper in the upper part ofthe cylinder that can reduce ring sealing and increase blowbyand oil consumption if not removed. The cylinder may also be outof round, scored or have other damage that requires correctingbefore a new set of rings will seal
Perspective On Using CBN Versus Polycrystalline Diamond (PCD) Cutters
In your June Shop Line you offered Jerry Lawson’s of DCM Tech, Inc., perspective on using CBN versus poly crystalline diamond (PCD) cutters. Have any other manufacturers voiced their opinions? In PERA’s May 1996 Current Concerns publication, Andy Rottler of Rottler Manufacturing made the following observations on CBN versus PCD cutters:Rottler says that due to
