3.5 pounds. There are a lotta kerf cuts in that stuff. Well worth the stiffness.
I weighed the hatch tonight before I put the exterior skin on. 43.5 pounds. (Can that be right?) I might have to downgrade my struts.

That sounds about right to me. I can lift ours by myself easily, except the shape and size makes it awkward.
However, you may want to weigh it as Dan Lott's figure suggests, after you have it hinged, for the gas strut calculation. I don't think the two numbers are necessarily the same.

I weighed it this morning. 49.5 pounds. l and re-ran Lott’s program and yes, I could use weaker struts but McMaster’s next one down for this length is too light.
Plan A it is.
I still need to glass it but the 6 oz cloth with epoxy won’t add much.
