Title: Bamboo backed ERC 45# @ 27”
Post by: Mo_coon-catcher on October 30, 2019, 08:13:28 am

Here’s a bamboo backed eastern red cedar I finally got around to getting done. It’s about 1 7/8” wide from fade to midlimb then tapers to 1/2” nocks. The limbs are 28” from fade to nock with 4” of handle and 2.5” for each fade. The bamboo was ground as thin as I could before glue up and was then trapped leaving a 3/4” wide strip of power fibers down the back. Set is just a little over an inch since I glued up in a flat profile. I got the bamboo from Kevin at this years mojam and the ERC was a board of perfect grained quartersawm board I got from Ed at mojam last year. I did a little tweak on the upper(right) limb on the tree somce I snapped the pic, to get a bit more bend in the mid limb to remove a little thump it had. I need to chrony it, since it’s a pretty quick little shooter. For its bulk it’s pretty low mass, I havnt weighed it yet, but the mass is about what you’d expect for a bow of this draw weight and length with a stiff handle, but just had a lot of width. I love the colors of this combo of materials and may go for another boo backed ERC in the future.

Thanks for looking,
Kyle

good for you Kyle!  I think you were wise using that profile rather than one with lots of stress.  It should make it a sweet shooting bow and reduce the chances of fretting the belly as well.  Looking forward to seeing/shooting that one or one like it at MoJam next July.   :OK

Looks good but I bring the bend back towards the handle a little more especially on the left limb.

Cool bow :) Interesting combo and bamboo use.
Your 'thump' is because the tiller is too circular. The width taper you describe should have a more elliptical tiller.

Thanks for the input everyone.

I can definitely see what you all are talking about. I was hoping for a tiller closer to the left limb with more of the bend a little further out on the limb, though I can see yhat flat spot about 6” out of the fade. But this was my first attempt at doing 99% of the work on the bow with a belt sander, and I ended up eating a bit more material just out of t. Fade on the right limb and spent my tillering trying to even that out, and ended up with a circular tiller on that limb. I may do some more tillering work.

 Nicely done! A bamboo/ERC longbow is on my shortlist of bows to build.  I think they can be a great combo for a very pleasant shooting longbow.

Nice looking bow Kyle.  I really like the looks of that combo.
