Hi all,
Here's one I tillered out yesterday. It's Ironbark with a backing of bamboo, glued on with just over 2 inches of Perry Reflex, and maintains about ½ inch of reflex after unstringing.. The making of this bow was pretty quick: I used the templates for the bowmaking classes I run, so a lot of time was saved in laying out, and much of the tillering was already done. Fifty pounds draw force at 28 inches. Sixty nine inches tip to tip, just a thin hair under 38 mm wide at the widest, and just slightly narrowed at the handle.
In fact the whole process went very quickly, as a result of maths, engineering, templates, good materials and good tools.
Marking and cutting out: c. 15 min
Preparing bamboo: c. 15 min
Glue up: c. 15 min
(Glue time omitted, but in essence it consisted of leaving the ssembly in the car parked in the sun for most of a day. It was easily 60 degrees Celsius in there.)
Post gluing tidy up: c. 20 min
Tillering: 18 minutes
---Yep. Between putting the string on the first time and full draw was 18 minutes, and less than ½ Oz of wood came off.
Sand & wax: 50 min.
Total time (ex. glue set time): circa 2 hrs 20 minutes.
Full draw:
Experimental overlays - still in beta/prototype phase
Ironbark is most usually a rich, dark brown to red. This pale timber still passes muster though.
Cheers,
Dave
