No special tricks , only Good file and gentle moves... I use ski files...
I find nice saw blade with 10 teeth per 2cm ... I filed only one side of the teeth - and counted file moves - 3 moves of the file and the side of the tooth gone from 90 degree to 45 degree angle...only some correction were needed - pretty quick job - maybe half an hour

Ahhh, so you're not making new teeth, you're modifying the existing ones! Sometimes I can be so slow. Thanks
BowEd:
gorazd....Yea that could just be the photo playing tricks.I used a recipricating saw blade.Around 12 grooves to the inch.Around 1/32" deep on the horn and core inner locking grooves too.Use a self made guide at first till the grooves get started.Some go with a lot more grooves.
I think your bow looks fine.Good luck.

I doubt the core will withstand the stresses.
why did you not bend in any kasan eye reflex? I presume you were worried about steaming the core?

I got the bamboo for free so I started to experiment with it 2 years ago...
With this turkish bow:
I did some bending of the core - but dry heat, but only in kasan area and not the sal. I thought that would be ok that.
Steam bending will destroy the bamboo floring I think - so I didnt even try this.
I choosed the bamboo flooring core because I have some positive experience with it.
I tried it before in one epoxy laminate bow (carbon lam + 5mm bamboo core + Gordon glass laminate). I saw that people use the same lam with good success in laminate bows using as core...
The core thickness in my turk bow is only 2.4mm - 4.5mm. The bending part with 2.4mm core thickness is over 10cm in length.
I did some testing with bending the bamboo flooring lam (same thickness - 2,4mm) and achieved the RADIUS of bending under 10cm without any damage.
So I hope it will held but cant be sure of course...
I have obtained some good looking maple boards and will try the next bow with maple too...
