Title: Ist backed bow attempt. How am I doing?
Post by: Red Dwarf on March 12, 2008, 11:27:08 pm

 ???

I have just removed my 1st attempt at a backed bow from the cawl.
It is a hickory backed elm board, 62" ntn, 1 1/2" wide for 1st 4" and then tapers to 3/4" tips at present.
It had 1/4" of deflex before the backing was applied, but came off of the cawl with 5/8 of reflex.
I have floor tillered as per Dean's facet method and have just tried it on a long string: it currently pulls 30# @ 6" on this long string.
Its mass is 18 oz and the reflex has increased by almost 1/8" with the removal of belly wood.
I am searching for 45# @ 26" but  am concerned that I may not have enough mass.
The board feels really "lively" in its present state.

I am feeling a little nervous on this one and would appreciate some guidance from you experienced guys.

Lots of weight left in that wood.  Try getting righty bending like lefty and you will be close to brace.  You could remove a little bit from the outer limbs also, but I would work on getting them bending the same first.  Justin

Lookin dandy to me ;D. Now that I focus, that right is a tad stiffer than the left - man that was hard to see. Thinking about making me one of those back boards to really fine tune a tiller. That is looking great though - really!!
