How To make Cams for Small Four-stroke Engines

I'm sure many would-be model engine builders have seen photos of the complicated Heath-Robinson like cam grinding machines that appear in the model engineering press from time to time and concluded that while they might like to have a go at a four-stroke, they don't have the time required to build a cam grinder, or the expense would be too ...

Anyone ever made a camshaft?

There are commercial cam grinding machines that can copy your existing cams also. Another possibility is to contact Megacycle Cams - they make a wide range of M/C cams and may have one for yours. I think that the suggestion of using the rocking bar principle to copy turn a cam does not work due to the change in top rake angle as the cam profile ...

Cam Grinding Machines - modelenginenews

The grinding wheel is mounted on a rocking arm that pivots on the third. It too can be repositioned and locked over the cam locations. A follower attached the arm rests on the master cam. The moment arms provide the scale-down factor from master to generated cams. The inter-connected shafts need to be rotated at a relatively slow but steady rate.

engine theory - What is crankshaft grinding and why is it ...

A crankshaft wears with use. After a lot of miles, the play between shaft and bearing becomes too much. The more play, the lower the oil pressure, the worse the lubrication. And then it wears out even faster. You can grind a crankshaft, camshaft, or any shaft to make it round again when it's worn out.

6 Causes of Grinding Chatter – And How to Fix Them

Grinding Cut Too Heavy Slow down your infeed amount so the machine is taking a lighter cut. Or, if you're traverse grinding, slow down your traverse fee. This will allow for your wheel to cut more freely and prevent any possible vibration or bouncing. Wheel Too Hard Try using a softer wheel, or make the wheel act softer.

» Centerless grinding of cam and crankshafts

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.
