Finally waited long enough to buy one of these Harbor Freight horizontal band saws.
Didn’t bother keeping the stock blade. Bought a new blade right off the bat and used it to set the alignment of the blade. It took a little doing, but it’s dialed in and cutting straight.
I found this document for aligning the blade and adjusting tracking. It’s still not tracking 100% on the lower drive wheel. But I think I have a plan on how to fix that with some help from the internet.
