Ya all wanna see a BBO build?

[Roy from Pa]

Question on Unibond again...Does it require the heat box or could it dry at room temp?

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.

Will you be keeping that fade angle on the riser?  Seems a little abrupt.

[Roy from Pa]

The riser will be rounded off a little  Mike.
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.

Ah Ken, what's ya saying there?> LOL

Well Roy , I'm purty sure you ain't a production builder ...

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.

BTW, I have a bow Roy made and it's waaay better than a production bow...

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....

Lookin okay so far Roy

Thanks Josh, I need to get back to the shop soon. Many things going on here as of late.

[Roy from Pa]

Sorry guys it's taking some time here.
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.

[Bryan Adolphe]

Roy take care of yourself there hope  you feeling better soon. 

[Roy from Pa]

Few pictures of rough shaping the riser in.
This is the process that got me messed up:)

Tips roughed in.

[Roy from Pa]

I do not use those real long tillering strings. My first string is locked into the string grooves and it lays snug against the belly of the bow.

This video may make you sea sick:) It's hard to hold the phone still and pull the tillering rope at the same time.
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.

[Roy from Pa]

After a couple hundred pulls and removing wood several times from the left limb and working the rope down the tree, the pull rope now tracks the line. It's being pulled to 19 inches down the tree here, but still with the long string on the bow. And after 6 beers, I thought it wise to stop tillering cause too many beers can do bad things to a wood bow:)

[Longcruise]

Am i seeing a sort of power lam under the purple heart of the riser?

[Roy from Pa]

Wouldn't call it a power lam, just wanted to add a different color in there.
