There are some pretty good chainsaw artist out there now days so I reckon it's OK for you to saw a trade bow out 

[kennym]

Now we cookin...


I mean really , got one in the easy bake oven...

[DVSHUNTER]

I'm making some final corrections requireing some steam.

I got a little done so far today. I can say, it takes a minute to rip lams off with a handsaw. The cedar plank is only 1/2" thick so I cut a piece of black cherry I will taper for a core. Since I need about 1-1.125" thick at the handle are. And it's gonna be a little chore as I will taper with a rasp before I clean it up on the belt sander.

You need to fix that spelling Kyle
Bamboo back ERC with cherry core, cool

[Mo_coon-catcher]

Thank you sir. I didn't catch that. I take time to make sure my spelling is correct while I'm typing the. I get a work or two down and my phone decides I used the wrong word.

I'm hoping it'll turn out like I'm hoping. We'll see. I'll probably spend my next working day on it. Today I'm fighting with a snaky Osage.

Actually..... The wood i selected for this swap bow was harvested and rough cut into slabs with my chainsaw many years ago. The black walnut came from large branches of a tree that still stands in the SE corner of our property, and the Curly maple came from rather large trees i was cutting for firewood on my neighbors 40 acre spread to the south of us....

i got the first footing laid up this morning, and have the second lay up cooking right now. I milled some very thin white ash branch wood i used for accent lines that came from yet another tree in my front yard. It should look pretty sharp....   Riser block photos tomorrow....

I've also started milling my lams and wedges.... the combination of fossilized bamboo, Black walnut, and rock hard maple will be used for  my first lay up experiment....

Well I missed weight. I was trying to see if i could make it work with this slim little snake, but I'm five pounds under the minimum draw weight asked for.  I'll have to setthis one aside for another time.  That sucks. It's 40@? And 64inches long...

[Kirkll]

Here is what the riser block looks like....

Got her milled, hardware installed, &  Ready to mount limbs, ground the lams and power wedges, and i'm ready for the first limb lay up...

I started a photo album for the build so its easier to post progress.    Kirk

Looking good so far Kirk
I like that you are stepping outside of your comfort zone.
You are guessing at a stack for the first layup??
Show all your "failure's" for hitting your target # please

That snakey bow looks interesting and nice riser blank Kirk.

[kennym]

Dave, I like 40# too...

That's the fun in this one Max.... The stack height is a total SWAG at this point. I didn't even reference my bowyers log.  It looks pretty beefy without glass, and I decided to use a double power lam for my wedge system rather than a solid wedge.

Doing this should  lengthen the working portion of the limb and help distribute the load over the full limb length more evenly, which is common with self bows and board bows. I've also left out the tip wedges I typically use with this limb design. I figured I could always use external wedges and add them to the belly side if needed.

Once I get this set strung up, I'll set up my video camera and we will see what happens. I think this ultimately is going to boil down to comprehension testing this fossilized bamboo belly. I ran a couple .002 maple tapers in the core and used thicker parallel fossilized bamboo lams belly and back for tiller adjustment.

The density of this particular resin impregnated woven bamboo is off the charts compared to any other bamboo I've used. So I'm thinking this will be the ultimate compression test.
I thought briefly about using IPE on the belly, as it's a known commodity with Tri lam  wood bows... but I figured what the hell... I'm going to give this new stuff a go.

Stay tuned.... Lay up today, fireworks tomorrow....      Kirk

I made some progress today. Got the fade tiller good and still within weight range. Showing my crude string groove marker. And the veneers. Also shoe shine flexible rasp. For tip material removal.

Been away for the week but the night before I left I was able to get my bow glued up.   Don't mind the sloppy excess glue.  I'm still working on getting my epoxy amounts right and it was cold so I wasn't getting it as thin.

Better to have more epoxy than not.
