| Reflex/Deflex Oryx horn bow buildalong (God willing!!) After reading the thread on Oryx horn bows, I've been inspired! I manged to buy a pair of Male Oryx horns from Glassman, on here, & decided to share my misadventures with you lot! I'm hoping to tiller it down to around 60# rather than just leave it natural & learn to draw 130#! Please bear with me on this buildalong, I've never attempted to build a bow before (other than bolting some ILF limbs onto somebody elses riser) so there's a fair chance I'll be doing loads of stuff that's wrong, bad or stupid. I'm guessing that this may take a while too, so excuse me if I don't update too often. Moving swiftly along...... I started out with the two horns & a Yew log for the riser...  I roughly (that word's gonn be seen quite often, I'd imagine!) marked out a basic riser shape, with a small shelf...  ...and started hacking it about with saw & rasp, to give me a rough (told ya!) shape...    Next job is tapering the ends of the riser to insert into the horns. I began roughing these out with a small carving axe & refined the shape a little further with the rasp, until both ends were a snug fit into the horns...   ....unfortunately the lower limb was just a little too snug...  The horn now has a 3" crack running down it's length, although I'm not too concerned at present.I'm sure I can sinew it back up before I glue the 3 pieces together. As you can see from the pics, the riser has a nice bit of natural deflex to it, unfortunately so does the top limb, soooooo along with trying to build a bow from scratch for the first time, learning how to tiller horn (???) & documenting the whole debacle on here, I'm also going to learn how to bend/straighten horn (I know the principle) & create a bit of reflex in the limbs! I'll be back with episode two tommorrow (If anyone's interested....)

| Best of luck, looking forward to part 2. Perhaps we should start the poll now though, "Which limbs are the best, Hoyt Oryx or W&W Buffalo" |

| LOL, good effort - thanks for sharing this with us. There's a pic in one of the bowyer's bibles which shows how to tie a not onto a tapered limb (which would not nessessitate cutting nocks). I'll see if I can get it on here for you. Rgds, Dave |

| Day two. #### ups a-go-go! Damage control & the MkII riser... Well, the pics from session 2 are going to have to follow. The Wife has gone out & taken the camera with her  Today was a bit of a flop & a lot of damage control. The Yew riser I made isn't long enough to go into the horns securely, so I've basically had to start from scratch!  I tried a very gentle flex of the bow & due to my impatience, lack of experience & very shaky knowledge of the leverage laws of physics, the top limb broke out a flake from the bottom of the horn  Still, lesson learnt. The Mark II version has a straighter grip, longer inserts into the horns & is made from solid Mahogany. Oh, and it doesn't have a shelf, so I can shoot it as Primitive I've cut out the pieces of horn that broke yesterday, rather than just sinewing them & reshaped the belly side of both horns. (Sorry you're having to imagine all this at the moment, I'll put pics in the proper places tommorrow morning ) I've taken the horn off at an angle at the belly side, to reduce stress in that area. When the horns are glued & bound in place there should now be very little pressure on the lower belly.Tommorrow should hopefully see a finished riser & a tillering tree all made up & ready for action! (If I get the limbs glued on, that is, & don't break anything else in the process!   )

| Dat two pics.... YEY! Jules came back with the camera, so here's the pics.... New riser, much longer into the horn than the original.....  The cut off horn ends, removing the damage.....   Fitted to the riser (just loose for now).....   It's all coming together!  .....  Next job is to glue & bind it all together, build a tiller tree & straighten & reflex the limbs. More to follow!
