My horn bow build-a-long
DC:
And this is one of the easy waits. Something like 6 months to a year for the sinew to dry.
bownarra:
Are you going to wait 6 months on the first bow though?? :)
You only need to leave it 2 months to be dry enough to tiller(if sinew is put on it thick layers). It probably isn't worth waiting that long on the first bow as it is likely to have 'issues'.
If you put your sinew on in 1mm thick layers 2 weeks drying time between layers is plenty. The very long drying times are only really for the sinew down the edges of the limbs. It can be 5mm thick there. Or for the very best performers once you have your methods totally down and you know nothing is going to go wrong during tillering.
DC:
That's good news. Thanks

$275 to make one, too rich for my blood. ;D ;D

OK back on my head. I can start shaping. I ground the excess horn off the edges so the bow will sit flat on a flat surface. I got a chip but it's where the horn will be tapering out to nothing. Horn can be brittle if you hit it the wrong way with a rasp. Then I figured where the centreline will be, double checked it and marked it all around with a compass. I couldn't see the pencil line so I covered the horn with masking tape and remarked it. I was pleased when the centreline was in the same spot ;D ;D. Then I laid out the width according to the measurements in "The Book". It looks very narrow.
Question for Bownarra In The Book he suggests making the kasan 2-3 mm wider for stability. Why just the kasan, wouldn't making the whole limb wider help the stability even more? It would mean making the limb thinner to maintain the DW I guess but isn't that doable?
