I know you are more familiar with what you are doing but I would try parallel for 8-9” then straight taper to the tips. That’s assuming the bamboo is thick enough on the ends. But make all but the last three inches not bend. But that’s me . IM watching and learning. Like it so far!

You must be in my head Arvin. I just did that! Anyway this makes me feel better the get the outers moving a little more. These bows tend to have more of a circular tiller. This also should lighten it up a bit too. Good call! I’ll post a few pics of it when closer to 55lbs.

How are you reducing this? I assume you will need to take some thickness off to drop that much weight. How do you do that with the bamboo limbs, as in what tool(s) are you using?

I’m just using rasps and sandpaper and block. I firstly reduced width about an 1/8th” on each side of limb approximately midway up the limb then tapered slightly to the tips. I also reduced thickness a little at a time and reassessed the effect at brace. I pull a tiny bit to work in the changes and continue. That’s it till I get close to 55lbs. I’m getting closer now. It better than the alternative I guess. Not having the reserve draw weight to play with. We shall see how it goes. It will be a crap shoot to some degree as I don’t want to full draw this bow yet till I get to the flats. But I should have a good indication on draw curve when I get closer to target draw. I’ll pull it to around 25-26” and then predict from there based on how my draw curve looks to forecast my 28” draw as close to 50lbs.
Selfbowman:
Dave we have to weigh the bow at desired draw weight and length. So you can guess the intended draw weight and use a shorter or longer arrow or retiller there which is a pain. I usually get them to full draw and not shoot them till I get there. Everyone does it differently.
