Title: woods compresion and tention question
Post by: 65x55 swedis on December 21, 2011, 03:52:50 pm
i was wondering what are some woods that handle tension good and other woods that handle compresion. just wondering what people think are the best for each catagory. i normally work with hickory or red oak and even yew when i can find some. just seeing what are some other options. thanks

I favor hickory for tension, partly because it's easy to work with, and osage for compression. Osage works like magic. That's just me though.

Tension - hickory,white oak,maple,elm and ash.
Compression - ipe,osage,hawthorn,greenheart,yew (but low bend resistance so needs to be thicker than most woods),spindle,hornbeam and black locust if you're careful ;)

I work with compression woods and sinew.
Top 3 compression woods- Incense cedar, yew and juniper

For me...

Compression strong: osage, yew heartwood, ipe, bloodwood, yellowheart, jatoba, lemonwood.

Tension strong: hickory, maple, ash, elm, bamboo, white oak, yew sapwood.

For tension strength I favor hickory, pecan, and elm - in that order.  Pecan is probably my personal favorite.

Maple is more of a compression wood. After MLB did their experiment 2 summers ago with maple wood bats and the way they tended to explode when they broke, its probably not a good choice for a backing. Just my opinion.

Not in my experience. I've made many maple backed bows, including a 90# tri-lam warbow. Maple backed osage is also a favourite. I think it's an excellent tension strong wood. It does also excel as a compression strong wood, if kept relatively wide and flat. It's my favourite wood for selfbows also.

Think the term Maple is too wide a term to be used in passing. Some use the term for the whole genus Acer.

I agree with Dwardo. Vine maple and big leaf maple are two totally different animals.

The maple bats prone to shattering are the lower density bats which are made from either Red or Silver Maple. Not quite the same concept as a  rock Maple back on a bow.

I'm also new to all of this, and I was wondering whether cherry or purpleheart were any good in compression.

Cherry is a decent belly wood, but it chrysalles easily. You have to tiller it perfectly, but if you do, it makes an excellent bow. Best to keep it wider and flat. I usually back it, but not with an over powering material (like bamboo). Maple works good.  ;)

Purpleheart? Don't know, but I use it a lot as a mid-lam in tri-lam ELBs. It works excellent in that application.

My personal favorite is purpleheart. I have a purpleheart back with hickory I have shot for years.

This is purpleheart (from a board) backed with hickory that I then covered with snake skin. 65" ntn, pulling in the mid 40's at 27"

This is my 1st purpleheart. 67" ntn pulling 50# @ 28. I have retired it after over 5 year service in the SCA. I can't guess how many thousands of arrows this has shot.

For me, purpleheart is easer & cheeper to get than osage. Go figure.
