New hornbow

[bownarra]

This is a new hornbow I am just about to start tillering. This is the first time it has been bent.

Sweet!

Acer pseudoplatanus core Fingers crossed

Looks good, how long is it?

[bownarra]

46" I think?  It is going to be for a 30" draw

[stuckinthemud]

Sycamore?!? Did you have any issues with warping?

[sleek]

How long ago did you lay down the sinew?

[bownarra]

No it seems pretty straight. I haven't strung it yet but...good so far.
It's been drying for around 4 months since the last layer. I do them in roughly 1mm thick layers. This thickness only needs 2 weeks to dry.

Just saw this I’m so watching this.

how much time between photos? or start to finish

[bownarra]

Probably about 10 minutes or so. I'll let it sit for a while at each stage but no need to wait long if you haven't removed any material. If Id've had to do any heat corrections or horn removal I would've let it sit longer.
One sal is more recurved than the other but that is likely just the sinew, the core/horn thickness and taper in both limbs was exactly the same prior to sinewing. This sort of difference normally sorts itself out as you get them strung and draw fully. At least it is worth getting it drawn some to see before doing anything else.
Other than cut the tips and nocks I haven't had chance to do anymore to it. Will get back to it soon.

I’ll be checking in. Just so you know someone is watching.

Incredibly cool. The mechanics/physics of bows just blows my mind...

[WhistlingBadger]

Wow.  Horn bows are amazing.

I can tell by your peg board this is not your first go around with horn bows.  A lot of hard work goes into building bows like that. I guessing they would have to be next to perfect not to fail. Are those bows as springy,and smooth to pull as they look. With the long siyahs, and small riser do you feel any hand shock  when you release the arrow, or are those shot thumb ring only?
