Sinew & Bow length

[Marc St Louis]

The Birch bow was 62" long and it's performance was excellent.  I have thought of cutting 2" off each tip of that BL bow and re-tillering it down to a more acceptable draw weight

Yep your right birch bow volume 20 bow thought it was maple sorry !

Im going to build the bow & find out the self bow in the the pic was the fastest bow I had ever made with fresh numbers well into the 180s 10 gpp & was shooting 12 gpp arrows well ,but the bow was to heavy draw for the design and eventualy broke down so here are my thoughts I could go hickory/sinew or a very narrow osage 65 ntn slight recurve 18-19 in. working limb the hickory would be the lighter mass but better compression strength on the osage, I have pristien staves in ethere well cured ?

It's nice to have some good old hickory around ready.Personally I can't remember ever sinewing an osage.Never really figured it needed it.At least in my world of types of bows.
Hickory on the other hand I think can benefit from sinew with the right design.Just plain heat treating hickory most times is enough for me too.

Hickory/sinew is a great combo my other hickory/sinew after it was cured for a year has never changed it shoots the same and consistent , even though hickory is not a great rated compression wood it works great in the last couple of backed bows I have made using it as a core wood !

and apparently even a lighter birch can benefit from an application of sinew? a wood not known for its elasticity. maybe anything can benefit from sinew with the correct design?
