Have done quite a few board bows in pyramid style for the kids. With the correct grain, there is no ring chasing involved. Mine are all tillered by sanding the belly. 4esttrekker has a classic build along for a pyramid. Highly recommend it!
Not having a decent band saw, mine get sawed to thickness on a table saw with the sawed side becoming the belly. Riser material is glued directly to the belly and then shaped on a spindle sander or a drum on a drill press. You need good glue when doing it that way. My first handle popped off using TB III.
Last one was a 70" mollegebat which followed the pyramid design out to about eight inches from the tips. Went down to about 3/4" wide at that point. There I glued a 1/4 inch thick slat of oak. After cutting the profile, tapered about 1 1/4" of the slat to avery thin wedge and then reduced the rest of the thicknesses as much as possible while still retaining enough stiffness to limit bending to the short fade area. Was able to take that tip lam down to a bit less than 1/16" without getting any bend in that last 7 or 8 inches. Limb tips were about 5/16" wide.
Shoots great, but ended up at only 26# at 28". Sorry for no pics, while doing these projects I'm usually so hyper focused that pics don't cross my mind.
sent that bow home with my 11 year old grandson just a few hours ago. Kinda long for him but he loves it.
