Hiker,
Just a thought. You might get less noise and vibration if you went to 3 blades instead of 4. 4 blades still pose some of the same on and off gyroscopic vibration problems associated with a 2 blade prop.

10-4 on that...
i thought i would need the extra power from 4 blades--turns out i don't..
my blades have a good angle at the hub -then i flatin out the leading edge down to the tips[and of course a airfoil shape on backside]makes for a good blade..saved a whole lot of cutting -rasping and sanding..with my angled hub cutouts..the blades were made from 1by4s..
im going to chop off another 3"s from the blades--of course i will have to reshape the
ends of the blades--soon i will have 4 little stubs stickin out if i cut any more. :]
wired in jerry delta-the alt does not have as much resistance[blades turn easyer]
and it puts out more power than wired in star--so it puts out good power with a smaller blade..it gets the power from the extra rpms..because theres less resistance=more rpm.
so no need for a big slow torky blade......least wise thats what i found out messin with my little alt........

just a addition ..
when i had the alt wired in star it would barely light up my 400watt.38 volt landing light--and the blades would want to stall--need for bigger blades..
when wired in jerry delta it would light up the 38v 400watt landing light[not to full bright but a whole lot brighter than star] and no blade stall[sure could hear the alt workin thou-bzzz]......im just tryin get the most from a compact unit..
