I'm really confused about how to use the lobes table bellow. For exemple cylider #1 Exaust closed 0 degrees Exaust open 130 it does not form the 50 angle within lobe flanks

Can anyone help me with that?
I don't remember how I figure that out for the old camshaft because I did a program on Mastercam to generate the G code and I don't want to use it again.

Thanks,

Edi

An update on the camshaft issue.
Reading the instructions with very close attention, I found what I was doing wrong.
It had to do with how to start the cutting of the first lobe. I was doing it backwards.
After having the understanding on how to start the machining, strictly following the table, I have cut the lobes.

The photo bellow shows the correct and the wrong camshaft. The one on the botton (black end) is the correct one. Please observe that the lobes are inverted

Hi John!
Yes, almost there!
I have finished the camshaft today ant tested it on the engine. It seems to be OK.
Tomorrow I will install the distributor and try to staTI4 again but, first I will machine a starting tool. I have purchased a OneWay bearing 5X9X9 which will be installed in a small shaft with a pocket in one end for the bearing and use a battery drill bit machine.
I have tried to use a Dremel machine with a pulley as per the project however, it did not work not enough power.

Tks,

Edi
