That sir is cool bow.  Someone will be very happy with it, and for a good cause as well.

Nice Kenny

Hey Kenny, I wish my Lab was as smart as yours. He has a rug just like that but will sit in whatever space has the most saw dust and dirt. Comes out looking like he got into a fight with a dust collector and lost!

But on the real, do you need an apprentice? I speak 14 languages, including Klingon, and have references from both living and dead presidents, and can also levitate. I understand this is for an intern position.

Ok, seriously serious now, I don't understand all your numbers. More specifically:

"a .125" butt on the .002" per inch taper."

Does this mean that your lam, at the riser, will be .125, then, as i'm looking at it from it's profile (edge grain) it will taper down .002" till the tips?

What's a "butt lam"?

You threw out a lot of numbers, and every time I heard butt my mind wandered and I started missing my wife, so I hope you don't find my questions ill timed. I've been reading all these lam threads with all these numbers and I haven't got a clue what they mean. Id love to start my first lam bow this spring if I gather enough knowledge. And sorry about the long post!

That is going to be another nice one. I just love seeing how other people put these things together. There is always something to learn from these posts. Thanks for taking the time to document your work for us aspiring bowyers.

As usual Kenny it will be a looker.   Cant wait to see the rest.

Maybe I shoulda said lam butt instead of butt lam!

The taper in ? is .125" at the butt(thick end) and tapers .002" per inch to the thin end. That is .072" over the 36" lam.

Hope I cleared that up for ya,I'm not much of a writer!

Nice work Kenny...I like the swing jig you set up.

[K30bowfisher]

With that jig, do you even have to sand, or does your saw cut good enough to just glue it up?

[kennym]

Thanks guys!!

I lightly sand off the bandsaw marks and give it the light leakage test,then finetune from there...

[fish n chicks]

Thanks for the info Kenny. Looks like I was on the right track. See, people do learn stuff here!

[Swissbow]

Kenny, those zebrano lams look absolutely stunning. Can't wait to see the end result. Bet it's going to be a beauty, as usual.

Getting ready to try this build again myself. Sent you a PM Kenny. As always, a beautiful bow Kenny.

[K. Mogensen]

Awesome...  :cool:

[kennym]

Thanks guys,be back on it Fri!!    

[FerretWYO]

Kenny that is awesome. I wish i was going to be at that event.

[kennym]

Randy, maybe Charlie would bid on it for ya.....    

OK, here we mark out the fade cuts..


Forgot to photo the fade grinding, I make mine 1/16" at one inch from end of fade, and a little over 1/8 (.140")at 2" from end.

Here we put the stop on the belly so the lams don't slide up over the corner. Makes a gap if they do,how do I know??  :p  




Here I skive the back lams to glue into 1 long one...



And the skive gluing setup, a 6' pc of 1/4" aluminum stock to keep em strait, plastic to keep the CA corralled,and clamp to bench with spring clamps...



If you CA both pcs. ,you have time to position and clamp before it sets...



Thats all for tonite!!

[KellyG]

   

[kennym]

Allright!

Glued the skived pcs together to make 1 long one. Makes an invisible joint almost with a little care....

 

Ground the fades on the riser while the glue was warming in the hot box, only about 50 in the shop. Better than outside,sposed to hit 16 this afternoon.

You can see the marks where I checked thickness at 1 and 2 inches...

 

Here are the bow parts ready to assemble into a bow (hopefully)...

 

Smooth on is mixed and air bubbles surfacing,,osage tongue depressor anyone?...

 


Now the fun part,don't wear anything you don't want glue on. Lucky for you, most of my clothes are not to worry about, so that saved the naked pics!!

Sorry, once again,no pics at glueup. Don't want to glue my camera!

Here she is in the form, put a few #s of air in and adjust your lams and riser. Also some fender washers with a hole drilled off center to swing up to catch the lam stack mid limb and a set a couple inches from the ends of the fades works wonders to keep everything where it needs to be. Just don't tighten em with the cordless drill!This will bind up and make a spot on limb edge without glue.

Also I wipe the squeeze out glue down into the plastic, you can then break off 90 % of it when she comes off the form...

 

Maybe tomorrow we can see if she makes weight!!

 

[kennym]

Well, where were we?

Oh yeah, put her to bed in the oven.  
Here she is just out,first the glue you can break right off if you wipe it down away from the edges of the limb where it squeezes out..



After I clean one side up pretty well with the disc sander and 36 or 40 grit,I run it thru the thickness sander and finish cleanup...



Next I peel the tape and put new on, always have a little glue on the tape,and my straitedge won't lay true on it...







Then new tape and we lay out a bow,I used a laser a few times,but if the bow isn't perfectly level across the limbs, I convinced myself I might get a bad read. So I use the tried and true string(sometimes both string and then laser)

Just mark center at center of riser,then center at limb tips. Clamp the string on the limb tips,and see if it is on center at the riser...



Now check at center...




Now I make a square mark at 12" from center each way(3" past fades), this is where I start my width taper toward tips,get a center mark here also..
