A 1 in x 6 in x 8 ft board of Jack Pine weighs about 10.4 lb (roughly 31 lb per cubic foot). Its Janka hardness of 570 lbf is harder than about 22% of the woods in our database.
Uses and working notes
Common uses: pulpwood, boxes and crates, pallets, poles, construction lumber.
Durability: Heartwood shows modest rot resistance at best, so it suits indoor or treated uses only.
Workability: Responds well to both hand and powered tools, taking glue and finish without much trouble.

How these numbers were sourced
MOE (1,350,000 lbf/in2), Janka (570 lbf) and shrinkage (T 6.6%, R 3.7%) from The Wood Database, which cites the USDA FPL Wood Handbook. Specific gravity 0.50 is the 12% MC value (page lists basic 0.40, 12% MC 0.50). No dimensional change coefficient given: Jack Pine has no exact row in the FPL/Hoadley table reproduced by Popular Woodworking, so CT/CR are omitted. Region, uses, durability and workability summarized from The Wood Database. Price indicative.
