You are correct big production BS use mostly steel and some Al wheels and there are advantages. The lower weight of those wheels help the saws come up to speed quickly which can save the cost of the saw several times over in labor in a production environment considering a Tanny GHE might well last 40 years or more. As hobbyists and non-production shop users we do not have the high quality Al or the steel option for new bandsaws, we have CI and Al. The Al saws tend to be the budget saws and therefore logic would dictate the Al wheels have not had the level of manufacturing tolerences and/or QC that the saws with cast wheels have. So the conventional wisdom says get CI wheels and it is often based on the questionable logic surrounding momentum when although CI wheels are usually favorable on most of the new equipment we buy it is due to the fact they are generally higher quality and not the added momentum for "cutting knots" which on the size saws we buy is pretty much a non-issue. To demonstrate this get a piece of 6" tall hardwood, bring the saw up to speed cut it off and immediately start cutting the wood and see how much wood the "momentum" cuts, there just isn't that much stored energy when compared to the energy provided by the motor. I would also submit that on hobby sized saws the amount of energy that it takes to keep the heavier cast wheels running is negligible compared to the overall power of the motor, that pretty much extends to production sized saws as well.
In the end if you had two otherwise identical bandsaws one with Al wheels and one with CI wheels and all the wheels were concentric, true and balanced to the same tolerences I highly doubt ANYONE could tell the difference in the two saws in use, assuming they didn't get to compare the run down times they would only know if they opened the doors.

I trued up a welded up aluminum Crescent bandsaw wheel that had been broken and welded up. This guy who I was buying wood for had it. Crescent was one of he old time heavy duty machine manufacturers. It was a 24" wheel. I barely got it into my lathe's gap bed.
just placed order through ebay, and got $55 cashback through bing. just emailed them and they got back to me quick. shipping went up $20 from yesterday. Shipping same day!

It came today.Terrible crate.I got it uncrated but didn't have time to do much else.
Got mine today, moved it into the shop and open air crate. CI Trunnion arrives tomorrow and will assemble then.
I was surprised at the color, Polar White suggests a bright stark white to me like snow. The white on mine is actually a very light cream or buff color.

Got mine too, and the freight driver was kind enough to unload it and wheel it right into the shop.
Had to think a bit about how to safely get it off the pallet once it was uncrated. By the way, the Taiwanese sure know how to drive in a nail
Just needs a plug now, and a few minor adjustments. Those Euro blade guides look decently beefy.
Yeah, and I love the colour
Don't take this the wrong way but, the Grizzly green reminds me of HF's stuff.
Is the white the same color as the Shop Fox machines Grizzly sells?
Could it be that Grizzly is blending the brands?
Not trying to deflate anyone's sails here and a savings is a savings although if I'm not mistaken the "Cool Green" 513 was on sale just before Christmas for $715 + $89 shipping for a total of $804. The P series 513 is $698 + $94 for a total of $792. This is a savings of.....$12.00 Maybe I'm missing something here

I believe Grizzy began new pricing January 1, 2010.
Current 'regular' price for the green 513 is $850+$94=$944
Current 'sale' price for the green 513 is $825+$95=$919
Comparing to old pricing usually leads to disappointment.
$12.00 less is better than $12.00 more
Anyway.... just heard from FedEx....
Delivery set for Monday, between 10am-5pm
