dont know what to think?
« on: September 22, 2019, 03:16:03 pm »
My bow dropped 15 pounds in total since it was made. i was shooting it today and noticed after shooting an arrow that it wasnt as hard to pull it back. i weighed it and it was down ten pounds. I went inside for 10 minutes and came back and weighed it again. it dropped another 5. dont know what to think happened! maybe the humidity got to it. it just stormed last night but still. 5 pounds in 10 minutes.

What are the specs Deerhunter? Specifically wood species? Did the brace height or tiller change? Pics?

Seems like it was loaded with water.   To green.

Is this the first change you've noticed since you first started shooting it?

PatB I noticed that it was taking more set than it probably should have, about 2 1/2". the bend looked really good! also I was shooting when one of the limbs hit something plastic when it was shoot. didnt look bad so i didnt worry. dont think thats it though.

kbear the wood is Hophorn Beam, as i said, it took alot of set and i dont know if set changes the tiller but it still looked good. brace height lowered a little. ill try to get pics.

Woodly I hope not! The stave was seasoned but then Nebraska is very very humid like florida. It seems to be around 70% but then it rains and dropps to 50% after. should have put tru-oil on it instead of Watco.

American Hornbeam always needs induced reflex,  and a deep belly heat treat to make a good bow.Hop Hornbeam may be the same, but I have never worked with it. You could still try it . It will help some.

That suggests that it is breaking down for some reason. A hinge, overdrawn for the length, or just a weakness in the wood quality.  I've never made one from HHB but I own an HHB made by GregB.  It seems to have no more tendency to pick up moisture than any other bow wood.  15 pounds lost is a bunch.  You said it's taking a lot of set.  Can you post an unbraced pic or 2?

Sounds like the bow is getting fully drawn for the first time and it cant handle it based off design and/or tiller. Its not a humidity issue or a species issue. I have made many HHB bows and I live in humid city USA. All self bows lose a pound or two after being shot and/or braced for extended periods of time.

Bows that aren't built to match a draw length take excessive set and lose poundage all the while.
