Ozbow

Considering all the trouble with the poor quality of clear glass lately, going back to the 'roots' with this bow was quite pleasing. Red Box and Silver Ash riser and 3 lams of 'coffee''boo and one 'accent' lam of natural 'boo. Black glass front and back Right on the money at 43# at 28'' and 68'' NTN.

Nah not enough Bite, only a Baby Redback. Looking Good Bob as usual. Cheers Roadie.

Nice Bob like the colour combo and nothing wrong with the black glass mate it all looks the goods, well done.

Cheers Wayno

thanks Roadie and Wayno.

Nothing wrong with coloured glass; looks good Bob.

yeah quite like the effect Jeff, next one in the oven has white glass each side.

Haven't used white glass for many a year now but I used it quite a bit for female customers when I was building a lot of bows. Jude's bow has white glass with a natural bamboo limb core and Hairy Oak riser; very nice IMO.

This one will have spalted PNG Walnut in the riser which has some whitish wood as well as dark streaks so thinking it might look ok too.I am wary now of using all 'natural' bamboo [flooring ] in lams as I have found it does not perform quite as well as the heat treated or caramelized 'boo does.Comparing identical bows as in lams stack etc, the bow with 'coffee' lams throws an arrow further and faster.

Should look good.

I was meaning natural bamboo lams, not the flooring. Out of all the limb core materials I have used nothing beats a good natural bamboo IMO. Getting it is the problem.

I realised you were referring to natural aka strip bamboo as against vertical laminated flooring which is why I put the flooring quote in brackets, but it is still an interesting observation in any case. It definitely has proved to it be so in my case but as you say the natural colour really does look better. sometimes as with this bow I juggle performance against aesthetic appeal and include one 'natural' lam as a contrast stripe.

Yeah I think the natural colour of bamboo looks great but with the flooring if the coffee colour gives you a bow with better performance it only makes sense to use it.

Hey Bob, looks awesome mate. Only the arrow rest is on the wrong side

Isn't amazing how things can go differently. Last year I broke into a box of coffee vertical bamboo and made a D/R bow with the same core thickness as my sons 70" NTN 58#@28" D/R bow that has natural colour vertical boo. It came in 10# lighter at 70" NTN. I piked it to 68" NTN and finished u with 54#@28".

Anyways, the bow looks great Bob.

Cheers... Rod

That is interesting Rod! That is at complete opposites to what my experience has been, so I wonder if it is just variance from box to box . My figures did show a performance differential favoring the 'coffee' yet you have found yours came in way light! Intriguing.

I have had similar problems with natural bamboo from different manufacturers.

Using the same core dimensions and glass the latest box of bamboo is yielding bows five to eight pounds underweight.

Unfortunately we do not know which species of bamboo is used in the boards.

I've just realised the implications of what you, Rod and Greybeard have said. Maybe it's not so much 'coffee' or caramelized versus 'natural', but more a case of differing properties between different samples of the bamboo flooring.
