Q:
That's funnier and funnier everytime I think about it but anyways. I had a few minutes lastnight to get started on making the adjustable cam sprocket after I finished a few rail orders. This one is cut the same as the Arizona Z car style (Same as Kameari in Japan). I will cut another when I get time. The next one will be the smaller hole like on the one JeffP has. I like the way his is made over the Arizona type (Personal prefrence). This does not mean there's anything wrong with the Arizona type or anything. He!!, they been running that same style in Japan for many years.

SPEED IS MY DRUG OF CHOICE..LET ME DRIVE!
A:
Is there a chance that the cam timing could slip if the bolts are the only means of securing it? I wonder if a roll pin or some other pin could be inserted into a hole to cure that. I was thinking about a different hole on each spoke that dosen't have a bolt, for 4 different settings.
Just a thought, so tell me if I am way off base.

what would be nice is say have a tooth for every degree of timing ...so you can just move it and click it in and its safe and wont spin on ya...(if that would occur)
A:
Atlas Copco times their 255mm Oil-Free Rotary Screw rotors internally with timing gears that ar FAR smaller than that!
Think of a 10" diameter blower style chunk of high speed steel spinning at 14,000 rpms 0.0015" from another 10" diameter blower style chunk of high speed steel spinning just as fast---and never touching.
Now, if for instance a 3/8" brass nut were to rattle free from a check valve on a recirculation line and get ingested in these same rotating elements, SURE, it will slip. It will also blow three 17mm diameter ball bearings into dust at the same time on the drive bearing support!
If you hit a valve, do you want the cam to slip a bit, or do you want it positively driven?
As long as nothing hits, there is MORE than enough clamping torque with the bolts shown to transmit camshaft loads to the valvetrain.
People Are Idiots, Just look around here and you will see!

oh ok i was thinking the cam had more load on it...
Damn Tony when you pass away you should donate your brain somwhere where we can all plug in and leech of the information!

Do we have to wait for him to pass away? j/k
