The weather is killing me.   Not terrible cold but with no heat I'm only good for about 15 minutes.   Kinda excited about this first run at a RC.

You gots yo'self some damn heavy maple then...  Last I looked maple was 44 lb. cu. ft....  And I can feel a drastic difference when I lift the two different woods...

The maple bow I posted was 53lb/cu.ft. I did a mollegabet style maple bow for my first and it was around that as well. I figured that was typical for hard maple....

If your maple is 44lb/cu.ft. then 57lb/cu.ft. would be a huge difference.

I'm just getting my info off wood data base...  I never weighed it...  Are you saying that you weighed your wood and calculated the cu. ft weight???

Tree Size: 80-115 ft (25-35 m) tall,

                 2-3 ft (.6-1.0 m) trunk diameter

Average Dried Weight: 44.0 lbs/ft3 (705 kg/m3)

Specific Gravity (Basic, 12% MC): .56, .71

Janka Hardness: 1,450 lbf (6,450 N)

Modulus of Rupture: 15,800 lbf/in2(109.0 MPa)

Elastic Modulus: 1,830,000 lbf/in2(12.62 GPa)

Crushing Strength: 7,830 lbf/in2 (54.0 MPa)

Shrinkage: Radial: 4.8%, Tangential: 9.9%,

                  Volumetric: 14.7%, T/R Ratio: 1.9

We’re likely talking about extremes here. As it says in the stats, “average dried weight”. A lot depends on the individual tree, where it grows, conditions, etc.
I’ve seen a sugar maple over 5’ wide for at least 8’ of trunk.
I have worked with a ton of black walnut. I don’t know what it says in the book, but I have some that’s hard and heavy and has a ring to it when you hit it and I have some that’s light and soft as pine.
All the jatoba that I have worked with has been heavy and hard and very strong. I find that it can be splintery though.

Yeah, I weighed the board before I started cutting it up just out of curiosity. It's easy to calculate the volume of a rectangular prism and a kitchen scale handles that much weight with no issues.

 :thumbsup: :thumbsup:   I know wood can vary but did not think it could vary that much... I thought 3 to 5 lbs. max...  Good to know...  Thanks...

That board is one hard, dense, stiff piece of maple. It worked like iron with hand tools and had a measured modulus of elasticity that was a good 30+% higher than the MOE numbers I have found in the databases in the software I use. I bought it at Home Depot, so who knows where it came from but it is one tough piece of lumber.

Got her cleaned up and ready to tiller, but I can't tiller her till I get my victim's info...

No pin knots showed up on this one:)

If I need something different I'll glue up another one.
