You don't want to make that one - it doesn't lift on the back stroke.
I.e., it drags on the teeth.

mmmm.... doesn't it depend on how often the saw is used? Drag on the
teeth will dull the blade, yes. But blades aren't horribly expensive,
and the application is once in a blue moon. Wholesale Tool has a 21"
blade, 4tpi for $6. Others are up to $20. If each cut ruins two
blades, that's 12-40 bucks for the cut. Which is only going to happen
once in a while.

So I'd consider building that power hacksaw a bit oversize. Okay, a
lot oversize. :-)
