Thanks for the kind word, Fred. I just wish the video had the bow on it so you could see how it was bending. But, from my perspective, you can feel it just a touch in the hand when you release the arrow, but I was also using a lighter arrow than I would like (it was about 450 grains). I'm guessing I would have felt less if I had used a 500-600 grain arrow. However, the arrow spine I was using was good and the arrows were hitting where I was looking.
Jeff, I used a jointer to get the bamboo and osage down to their current size (the osage I got from Carson @ Echo Archery in 5/16" thickness... I got the boo from him too!). I have a picture of the jointer on my phone... it's an old beast, but it gets the job done!
For the walnut, I actually ripped it from a bigger board. I used a table saw to get the width and to cut that smaller board in half for the thickness (it was a 1 x 10 that was 6" long... if I had a better bandsaw, I would use that instead). I managed to get a 1/4" thick board from cutting it with the table saw. From there, I used a DeWalt planer to get it down to 3/16. That planer is sweet for getting boards down to 1/8" thick, but I haven't figured out a way to use it to put a taper on my lams (it's a bit more difficult since it's using blades to cut the board to size... I would LOVE a sanding planer, but that's a little out of the budget!).
To taper them, I'll get the taper close using the spindle sander that the form is resting on in the form pic. Then, once the taper is close, I use a hand planer to get it the rest of the way.
