A cam is a bump on a circle. When the lifter is riding on the circle, it's at zero lift. as the cam rotates, the lifter sides over the bump. Regrinding a cam is making the circle smaller, in order to make the bump bigger so it can be reshaped. David. four-thirteen, Dec 1, 2004.

When the cam lobe is rotated 5°, and a second cut is made, a small nibble is taken from the corner of the remaining lobe. This is the blank after 10 rotations. This is the final product after 47 rotations. After the 47th cut, the lobe has formed but the nose has 2 sharp corners. I used a small diamond file and rounded the edges off and ...

A master is a large cam that the manual cam grinder follows to grind your finished lobe, and it looks nothing like a finished lobe. The work (and math - lotsa math) needed to make one is large and expensive, even when you have the desired timing events on paper, and is usually amortized over hundreds of finished cams the way a pattern is ...

So, let's put the myth of the .010˝/.010" shaft to bed and move on into the 21st century. It's time to recognize that the strength of every reground shaft is the same no matter what undersize it is as long as the fillet radius is machined right. Our job is to make sure that the radius is done right. n. Advertisement.

The Sherline cam grinder was designed with the home shop machinist in mind. We have assumed that the user has some knowledge of g-code, CNC, and how to square up or "tram in" a machine, so all axes are properly aligned. The machine is carefully pre-aligned at the factory, but rough handling in shipping could knock something out of alignment

One of my current projects is turning an old van norman piston grinder into a cam grinder for small engines (cam length up to 10"). Took me a year to find the machine. So far the worst part has been trying to work up a plan for indexing the cams in the machine for various centerlines. This will save on the amount of patterns I need to make.
BMW said "in very rare cases the bolts holding the variable camshaft timing (Vanos) unit housing may become loose or, in extreme cases, break." In such cases, the driver would be alerted by a check-engine warning light. Power to the engine could be reduced and "if ignored, the problem can become progressively worse, eventually leading to ...
2004 Mini Bike madness was in full swing in the moto industry and after a lot of customer demand, I developed a line of mini bike and scooter camshafts. During the mini bike craze I ground camshafts and built motors for Jeremy McGrath, Twitch, Shae Bentley and many others; I also built one of the first blown alcohol mini motorcycles.
Valve lifters play a key role in the valvetrain of pushrod engines. They go all the way back to the earliest days of the internal combustion engine. The earliest engines did not have pushrods or rocker arms. They were a "flathead" design with the valves in the block. The lifters (also called "tappets" because of the clattering noise they produced) rode on the cam lobes in …
