Osage came from Kenny M.
I prefer 1/4 sawn lams.
I run the Osage lams through the drum sander to an even 1/4" thickness.

Then do a Z splice and glue up with EA40.

Patterns for taper rate were supplied from Kenny M.
Cutting out a section of bamboo, I split it with a machette.
How I flatten the belly side of the boo.
At this point the nodes are not a problem, I just need a flat surface to layout my bows pattern.

I then sand to the line and then taper the boo from 1/8th at the riser to 1/16th at the tips.
Before glue up, I lay all 3 pieces together and string end to end again to get it straight. Then I drill 2 holes in the riser section where the leather grip will cover them later, and drill a hole on each side of the tips for toothpicks to hold things straight when gluing up.

I can position the mid limb center posts to get more or less deflex or reflex.
Wrapped in plastic wrap and clamped up on 2 inch spacing and the back of the boo is protected with little sections of bamboo cut out. I alternate the clamp position from side to side.

And I miss making bows:)
I layout the Z splice with a ruler then I cut it out on the bandsaw just leaving the line.
Then I fine tune it with my bench belt sander. The belt sander has that narrow backing plate that only goes about half way up the back of the belt. So I slide the Z splice into just the belt right above that backing plate. Simple as chit. I keep working it till I get a perfect fit. I Iike to have maybe a 1/64th gap for glue to settle into.

1/8" at the center of riser or at the tip of the fades???
Very exciting watching all those pieces going threw the sander in super slow mode. :bigsmyl:
You use lams on the form to protect the Osage?

Center of riser.
I slowed it down so you could comprendo there snickles:)
Yes old lams, had the same pair for years.

Then do a Z splice and glue up with EA40.
It's always great to see your builds, Roy.
I just wanted to throw something out there about the Z-splice. Since it's on the compression side and you are gluing a handle over that area anyway, why not use just a 30 or 45 degree angle cut across the lams? It's easier to get a good tight glue joint with everything straight (though I think you have enough extra width that isn't a problem for you) and the strength of the joint is more than adequate for the job.
Just a thought...

Nothing wrong with that and I understand challenging yourself to get it right. Once hunting season is over here I will be back to working on my next bow and I plan on using a 30 degree angle cut to splice the core and belly lam pieces together, so I will see if I have it right or not.

Question on Unibond again...Does it require the heat box or could it dry at room temp?
Post by: Roy from Pa on December 08, 2022, 03:18:49 PM
No it does not require a heat box, it will dry in 24 hours at 70 degrees.
But do not let it get any colder than 70 degrees.
Some guys throw a blanket over the bow form and place a light bulb under it to keep the temp up.

4 inches of the center of the riser is the handle grip area.
And the ends of the riser will be feathered into the limb.

Neither Unibond nor EA-40 "require" a hot box to cure. They only need temps above 70F for 24 hours. Hot boxes are for production builders, or really old guys who need to get bows done before they get much older.
Or guy's that don't live in Florida! Its easier to heat 10 cubic ft of box to 150deg, than 3,200 cuft of shop to 70deg.

I like Uni Bond for doing a lot of laminations like building a butcher block, or parkey pattern desk top, or furniture with dark wood. The blanket over a light bulb works well in cooler weather.
I can't remember the last time i used my hot box on anything. I'm not what i call a production builder, but typically build 30-40 custom bows a year, & i use heat strips in my bow forms... Great for old guys that dont like lifting heavy forms in and out of a hot box, and your forms last much longer too....

I got a bad reaction from IPE 10 years ago that messed up my immune system. Well this is my first bow with purple heart and it's causing me problems. My face is burning, my lips are chapped and my hands are itchy as heck and I'm stuffy.
I've since then gone to more protection. I have the bow on the tillering tree and it's looking good. I have a bunch of pictures and a few videos. I'll get those up soon.

I tiller for equal limb timing and I want the pull rope to track that black center line on the wall. You can see it is drifting to the left 1/4" towards the bottom limb. That means the limb to the left is stronger than the right limb so I will need to remove some wood off the left limb. I want that pull rope tracking the line ASAP and I will not pull the bow any further till I achieve that tracking.

So I had to grind both limbs down on the edges using the edge sander which is always a challenge. Then I had to redo the facets. Strung her up and had some slight limb twist so corrected that. Here she is first time strung up after all the above. Looks pretty darn good to me at 4.5" brace height. Now I can start tillering again.

I can't remember, is you riser able to pivot? that spring clamp isn't much to hold it to the tiller tree.
When you shoot (or the way your tiller tree set up) is your whole palm pushing the bow or just the crotch of your thumb and index finger?
Doing the math and holding the bow with a arrow on the shelf (split finger), my middle finger is just under a 1/2" under the shelf (my pull hook is 1/2" under the shelf) and make the hook not drift left or right.
Post by: Roy from Pa on January 20, 2023, 08:55:49 AM
Another thing you need to consider is when your bow is done and you are shooting, the nocking point on the string is usually 1/2" + or - a tad to get good arrow flight. I shoot 3 fingers under and my nocking point is usually 5/8th above the shelf on all my bows, even glass recurves. So I set the tree up taking the 5/8th higher nocking point on the string into consideration. And I place the nocking point at 5/8th high when the bow is all done.. When I shoot my BBO bows my palm is pretty much flat on the grip with a tad more pressure at the shelf. When I shoot my recurves and they have more of a pistol grip, I hold the bow with my thumb and fore finger and let my other finger's hang free and the pull weight of the bow is all in the web between my thumb and fore finger. I have a wrist strap on my recurve and I just let the bow pivot forward after I shoot.
