This seems to be a fairly common question from bowyers who have 5-10 bow builds under their belts:
I was wondering if I have to handle the reflex reflex and the reflex deflex staves any differently than past Traditional bow builds. Are there any major difference in how I need to handle the different staves. Thank you again. I look forward to making more- and better- bows all the time.
At the risk of simplifying the tillering process of R/R and R/D staves too much, the main differences between tillering those two styles and compared to tillering traditional limb staves (into bows) is that you must be a bit more careful in removing material from the mid limbs.
Imagine "teaching" a backward bending piece of wood to arc correctly and gracefully in the opposite direction.
The first 4 steps in my version of bow building- floor tillering the stave, filing to the profile lines, beveling the bamboo backing and removing wood from the sidelines to the center line is pretty much the same as when you are building bows from trad or slightly reflexed staves.
The difference becomes very apparent once you are able to string the stave. The curve you might be expecting to see looks more like the sharp angle of a gull's wing!
Look closely at removing material from approx. 6" from the tips to approx. 4" above and below the riser areas.
Take it slow, keeping in mind that a little goes a long way when building bows from staves possessing extreme levels of tension.
