Building my own SOHC Rocker Arms

[jayb]

Mario, that would really be interesting!  It would be a good comparison showing a new machine compared to an older one.

FYI I talked yesterday to my local friend who runs a CNC shop filled with Milltronics machines, and he suggested I measure the backlash on the three axes.  X axis was .0023", Y was .0021", and Z was zero backlash as far as I could tell.  So the backlash is not the primary issue with this machine; the ballscrews appear to be reasonably good.  I think it is the shock of the table vibrating when the cuts are aggressive that is causing the problem; I'll bet the encoders are skipping steps, or double counting pulses or something when this is going on.

Hi Jay,

I wanted to check in and see if you've been able to secure any of the alloy bar stock you were looking for?  Are the rocker arms on the back-burner for now?

Cheers
Joe

Yes, they have been put on the back burner again; I'm trying to get done with my sheet metal intake manifold for my high riser project, and also get going on building my smaller SOHC.  I should be back on the rocker arm project sometime towards the end of March.
