Boo Yew RD
« on: July 02, 2020, 12:59:29 pm »
This is my latest attempt at 200fps. It's a Boo backed Yew 65"NTN following the curves. 1.25" wide at the fades tapering evenly to .75" at the base of the recurves. Tips are .4" wide. Weighs 492grams(17 1/2 oz). Draws 39#@28". Shoots 198fps@10gpp. Close but no cigar :D When I took it off the caul it had 5 3/4" of reflex. By the time I'd finished tillering it was down to 3 1/4". It was shooting around 195fps. I decided to try a 250 grain arrow. It shot 221fps but split the shoulders off the pin nocks. Don't use 6 strand D97 strings on pin nocks :D. You can see the splits in one of the pics. The string slide about 6" under the boo splits. I thought it was done for but I CA'ed the splits down. I had to pike it an inch because the tip was too damaged. So now it has 2 1/4" reflex. It gained 2# DW so I tidied up the tiller a touch and it ended at 39# but it shot 198 so I was pleased. I'm satisfied with the FD pic but the braced one shows that the bottom limb is too stiff. I may fix that, I'm undecided. I haven't shot it much so that will be the deciding point.

PS I just traced it out and flipped it and the lower limb has 3/8" more reflex so maybe the tiller is OK

PPS bad news. My scale has three options pounds, kilograms and jin. A Jin is a Chinese weight that equals 1.1023 pounds. My scale somehow got on "Jin" which is close enough that I didn't notice. So once I put it on "pounds" the bow weighs 42#, not 39#. This means my arrow was too light. True speed is 191fps. I'm bummed. I'm not sure when the scale got changed. I'm hoping it was recently. I thought this was too good to be true.

That's definitely a recurve and a very nice one at that. Well done.   :OK

How do you do your recurves??? Are you bending the yew and the bamboo separately then gluing up on the caul?  I've not come up with a great solution yet.  Thank you sir and strong work!!!

Yes, I bend them separately. I steam the Yew and bend the Boo with a heat gun. Just heat the outside of the Boo and push it into a concave caul. It takes about two minutes to heat and bend, and about ten minutes to cool. I'll post a pic of the caul tomorrow.

Very nice DC! How do you like the belly lam over handle design? I have always pondered trying it but haven’t attempted it yet.

That is a great bow!  Very impressive results. Do you happen to have a photo of your caul?  Thanks!

Very nice and fast DC.  Have you built a fifty pounder like that? And would you get those # s  with 50#Bow and a 450 gr arrow. Next why are you not at wendover? Arvin

Good question. I didn't notice that on first look at the pics as I was too busy admiring the super clean detail work. Running the lam up the fades is the ultimate solution to handles popping off.

DC, did you steam and pre-bend the belly lams to fit up the fades?

Why would the poundage matter much when the arrows are normalized to 10gpp?

I kinda like the look. I can get an extra 2.5" in length so I can use shorter billets. There is a bit of fiddling to get a decent glue line. These aren't as good as they look in the pictures. Sometimes a blurry camera is a blessing. I steam the belly to the curve I want and then trace that shape on to the riser. Then cut that out with the band saw.
