Tractor "sediment bowls" are available at TSC for about $55 Canadian.

They have glass bouls thugh, and in Canada you will not get the OK on
a homebuilt / experimental with a glass bowl.

Didn't know that. Got a glass one on my Jodel, but it was
licensed in the '70s. It's a thickwalled (1/4" or 5/16" thick) glass
tube, actually, with cast aluminum or zinc top and bottom pieces. Not
likely to break unless I drop it on the concrete at annual time.
I think, since we have a lathe and mill here, I'll just buy a
chunk of 2" 6061T6 aluminum round bar and machine my own for the
Hummelbird. 2011T3 would be better if I could find it.
