Hi Wayne, Iv'e been watching this one closely. Whats happening?

fujimo

been off it for the last two weeks- full into the rut right now-   :scared:   not me ...the deer- weeeell ....me too i guess  :D    :D  
anyway...i did get the form made for the spruce tip inlays
was fabricating and welding up all the brackets,  need to finish with the router work on the form- then ready to have a good crack at it.

Rut or no rut, this is slow going and suspense is almost killing us.   ;)  Bue--.

hey, i can use whatever i want to build a canadian bow, eh!   :D

ok so the forms were finished- both the main form, and the form for the static tip inserts.
next was prepping materials for the tips,
some good ol sitka spruce


nice tight , straight grained stuff



030 clear glass
2x .100 lams with 002 taper,
riser and inserts

black limba for lams and riser cheeks,
maple and ipe for i beam
spruce for tip inserts

besides i am not much of a bowyer  Ol' fella- so figure i can get away with it!!

the concept for the spruce tip inserts came from mark daniel- and he did that with his very pronounced static tip 3 piece bow-with string bridges an' all.
so he did all the smart R and D- i am just working to his idea.

fujimo

ground lams- on my trusty Kenny-m sleds   :D   , spliced the lams- was very worried about them busting at the splice with the pronounced curve in the riser on the back, so glued them up with smooth on instead-.
 

shaped and sanded the riser, and trimmed and sanded the limb tip inserts to a feather!
 

fujimo

the snakey profile under the riser is a laminated piece that i lay on the form, when final shaping the riser- it is made up to match the combo of glass and wood lam, incl the tapers- it was laminated from 3 layers , so that it will hold its shape well- that way i dont have to repeatedly flex the splice joint when test fitting the riser. its only a tad longer than the actual riser

Coming along nicely. Good idea with the snakey profile . Bue--.

you like the wood Dave   :D  
it completely changes under glass- i can now see why you love it!

using the trick i learnt on here from some ol fella in Pa, using a toothpick to line everything up in the riser area- makes life so easy nowadays

got it into the form, getting the insert sandwiched between the lams at the tip was going to be really tricky- did a few dry runs, with the wood being dry, it was really hard to get it set up perfectly, but knew with the glue bing slippery i could get it to work


so glued it all up, inserted the wedge- about 10# pressure- then with the glue helping i could slide it into the perfect position, , air in small bursts over about 20 minutes- checking that it was well seated the whole time.
got it into the oven- to get up at 3;50 am to switch the oven off!
