HHB has a tendency to have spiral growth.  Before you cut a tree down examine the bark carefully, you can see the spiral growth in the bark

Absolutely good advise here.  This can save you lots of trouble when you got to work the stave layer on.  I also like JW advise with the spacers for drying.  I’ll have to try that one!   The bows I’ve made from hhb have been great bows btw.  The trick is finding straight run without twist.

Cool project!  I’ve never built one like that with the grain run that way.  Mine have all been typical grain found in stave wood.  Even belly drop bows I’ve made like this have the grain running the typical way.  Should be interesting how the wood holds up for ya.  I know guys have built them this way and got shooters so it must be doable.  Sinew looks good!  I use the same glue pot which is a repurposed wax pot!   Cools stuff.  Keep us updated on progress

Bows / Eastern Red Cedar/Sinew Buildalong

here's a link to a buildalong I just started.

Hopefully it holds together, though I'll learn a ton if it blows up.

Thanks for looking!

2 weeks later

The bow has taken close to 3 inches of reflex total. In about another week or two I will start tillering it and will update the thread then.

Thanks for looking!

This is the bow 24 hours later after removing the wrap.

I took a profile photo to show before and after shots of the bow being reflexed by the 110 grams of sinew.

I then applied the second layer of sinew. I again sized the bow generously with thin hide glue and waited for it to gel before proceeding.

This one is 60 grams (total of 110 grams).

For the second layer, I first applied short pieces in any gaps there were. Then using the longest pieces of dog chew sinew I covered the whole back once more extending down the sides about one third of the way and back over the nock areas and anywhere that had been applied unevenly the first layer.

For this and the first layer I made sure each side received the same amount of sinew.

Last of the first layer applied.

I wrapped the bow with innertubes and let it sit 24 hours at 70 degrees and 50 % RH before removing the wrap (I like the smooth compression).

The second layer will be applied pretty much right away.

In preparation for the first layer of sinew the back was first degreased using rubbing alcohol.

I then sized the whole back and ends of the bow with thin hide glue. I made sure the nocks were covered on the belly side and that the sizing went down the sides of the bow some as these will all receive sinew.

About a half hour later I started to apply the first layer. I resized the bow and each bundle of sinew was dipped in thin glue, smoothed straight and most of the glue squeezed out of each bundle before applying (I like doing it this way it's less messy).

The first layer (50g) was applied evenly over the back and over the nocks, but not over the sides,

The back was crowned slightly and the nock ends and sides (down 1/3) will be covered thoroughly with the second layer.
