Thanks for adding that Mike I was going to use it but was afraid it would dry the horn out I have a 0.005 actionboo tapper sled comming from one of the guys on another site figured I would use it as a pattern it was cheaper then buying the materials to make it !

I didn't have a lot of time this morning but got a chance to lay out and make a limb templet from 1/8 in. Pattern ply wood for laying out the horn , you really get a concept of how short and narrow one of these bows are  when you lay it out , also got a friend from another site Kenny to make me a 0.005 tapper sled for the horn , I'm going to double check all the measurements & start laying out the core next & build a Dean Torges style form for glue up !

Brad it's basically a platform bed that's tapered like a bow limb that drops Aprox. 1/32 every 6 in. the horn is put on it basically as a parallel lam and feed thru the drum sander so that tapper is ground into the horn and the core is done by hand with the same tapper so when it's glued up it has a tapper that drops Aprox 1/16 every 6 in. the only problem with using it for horn is with the slight bow in the horn the pressure rollers on the drum sander won't hold the horn flat enough for a precession grind so I will have to secure it with double back tape it's really important on these bows that it's done right 90% of the tiller is done before the bow is strung ! Also the tapper sled is wide enough that both horns can be done at the same time to get exact twins !

Brad these bows can be done all by hand to ,so it's not that complicated it takes far less talent to use the machine so don't let that scar you if your thinking of making one  )W(

Got a chance to work the core a bit today every thing that I have studied over the last year says that the core and the core selection is the most critical part of making a composite and realy good sugar maple is hard to find but I got lucky and found this stave I decrowned it last year and it's been inside at 50% RH or lower for a year, at the apex  of the crown perfect strait grain lines up for the whole length got lucky ! This is where making the limb templet realy helped with exact dimensions I laid out the center line & handle ,fade locations put the templet on the center line traced it rechecked the numbers and done with front view layout as long as I maintain the center line I can check or redraw the layout any time I left the lever fades & leavers wide so I can lay out the tappers and bend the hooks I cut the profile close on the band saw and snuck them in closer whith the osolating sander (thanks Ed for talking me into geting it ) I also changed the bow lay out from Ed's plains his was 58 TTT I'm extending my leavers out 2 more inches per limb for 62 TTT  with the hopes of a lighter 45-47 lb draw weight  next is laying out the side view and tappers !
