PS Thanks for sharing. I really would like to try a sinew-HHB- horn.

You totally should be! It would be an awesome combo. Hhb is pretty dense and hard obviously. You could go little thinner on your horn then I did here. I would say a 50% wood core with 20-25% horn and 25-30% sinew as far as thickness ratios. This is the ratios I use for my bamboo core horn and sinew builds. Bamboo is very dense stuff too and this ratio works well.

Well a quick update on this crazy project. It’s awesome! What a great combo this little bow became. The boo backed hickory bellied with buff horn with a splice for length ended up really great shooter. My fastest speed out of this bow this morning was 194fps at 29-30” draw which is close to 42lbs shooting a 380 grain arrow. At 28” draw it’s right at 39.5-40lbs. The grip ended up a little small for me and my gorilla hands so this will be my wife’s new bow. I had to remove some draw weight from around 50lbs to the 40lbs in order for it to work for her. I had taken this pretillered bow and reduced it down to around the 25-30lbs mark in order to add the belly horn slat lamination. this added 20lbs! Horn adds a lot. She did some shooting with it too this morning after I put a few dozen shots through it and didn’t explode. I guess she is used to hearing me blow up my experimental bows! At her draw around 26” it’s about 35-36lbs draw which is perfect for her. The splice on the horn to lengthen was really the experiment for this one. I figured the horn would be a good match up with the hickory and boo backing. The pre tiller saved me a lot of time on this one and finnished up pretty quickly. Ill be making more of these and may see if i can get my hands on some longer horn slats and build another. the z splice functioned well after several dozen shots just fine but im not crazy about the asthetics of the splice. in retrospect i should have done a v splice about 2" long that was centered to look better. anyway a good test and to my estimation a pass. Also another crazy observation... its reflex is holding strong at 6". upon glueing up the horn I had added about and inch extra onto the 4.5" reflex and clamped it all down to let glue set. after unwraping it and cleaning it all up a bit i noticed it was around the expected 5.5" or so. I put a few shots through it and it was a little over 50lbs. felt really fast but was getting dark so i shut it down for the night. got back at it the morning and my wife commented on how much she liked it. the grip was a little small for me so i reduced the weight. upon doing this the reflex increased to 6". ahhh what now??? The only explanation i can think of for this is the increased compression of the horn was stabilizing the tendancy of the tension stiff bamboo to pull more reflex as the horn was reduced. still scratching my head though on this one. If anyone has a better explanation Id love to hear it.
