Thanks guys. Stix. Yes it’s a good shooter. Juan, I will do that and post it on this build with a short vid link. Stay tuned.

Hey guys. I was asked about my boo strip prepare method so figured I’d post it here on this post as it applies to this build too. Basically what I do as can be seen in the video clip is lightly heat temper or treat the belly of the strip and very lightly heat the back a little too not so much to toast it like I do on the belly but enough to get steam escaping as can be seen. Too much and your boo strip will be too brittle and could find yourself is a situation where something explodes. Don’t ask how I know this! In the video you can see I’m moving back and forth over a radiant heat source. This is just what I’ve found works for me. You will get a smell similar to popcorn or slightly burnt popcorn when doing this. My wife hates it! Lol. You may also actually hear the steam coming out of the strip. In the pics here you can see the the belly side does swell a tiny bit so like I said before on this thread you’ll have to resurface the belly prior to glue up. The results I think are noticeable. Can’t say it’s just this one aspect that makes all the difference between these two bows and others I’ve done but a few things done and minor tweak’s combined I think added up to make the difference. Time will tell on the longevity of these bows have retained this much reflex being all wood laminates but one can be hopeful and it’s the little tweaks that sometimes make the difference. In the pics you can see that after heat treatment this little 23” test piece in the demonstration loses about 11grams of mass. From 165 grams to 154 grams. Water weight loss. You’ll also notice that the first pic shows the slight swell on the belly. As I mention in the video the lignins and pectins in the boo harden up much like sugars and starches do when heated. This was discovered to improve moe and overall strength of the boo. There is a great study that was done in china I believe that I referenced when doing my own testing for its application to bows. They were studying the benefits of heat treatment of bamboo for application in construction. Anyway enjoy the video and thanks for following along in my builds and hair brained ideas.

Sweet bow Dave
It would be so cool to get a bunch of us to the flats with Arvin.
I’m sure it would be a great learning experience for everyone involved.
I to have been the benefactor of help from Arvin.
I have a flight bow ready almost ready to go. Need a different string and a little finish work.
I just can’t get away in September I believe?
Sure would be a hoot

Thanks Bj. Yes for sure. That would be a great time. We will have to do it one of these years. I might be able to swing it for next year! I’ll reach out to Arvin and see if we can plan for it and make it happen. He’s got me getting keen on the flight stuff and all the voodoo magic that goes with it. 😎.

I was able get a better full draw pic uploaded. Hope this looks little better. Cheers
Dave.
