It's trilam season again

[Bvas]

Looks like Tim is doin great on his first bow.    

[Roy from Pa]

Buffalo horn.
I put mine on the back burner while Tim is building his.. And a little 7up...

The official start of Trilam season.  I guess I need to finish tillering my trilam that I started months ago.  
It's looking good.  Did you use the same amount of reflex/deflex as your normal setup?  
That one looks like there's more reflex.

[Roy from Pa]

I put in more reflex and less deflex. I do that by moving the mid limb post out more towards the tips.

Tim was here yesterday. He brought a case of water.. What's wrong with this guy? LOL      

Bow on the tree for the first time. The bottom limb to the left is a little stiff, we worked on that for a while.

 

Bottom limb starting to come around.

 

At rest after being pulled to 19 inches with the long string. It's ready for a 4 inch brace height, but I realized I gave my only longbow stringer to the grandson a couple weeks ago. DUH.. So today I will make a couple longbow stringers..

Video here. Top limb to the right needs to open up just a tad more.

Roy, do you like the full draw to have stiff, unbending outer limbs(slightly reflexed) or a full circular tiller throughout from tip to tip on a R/D style bow?

[Roy from Pa]

Circular, Pat. I used to flip the tips with heat before glue up to get the slight reflex at full draw but it seemed to be harder to tiller that way. Almost seemed like making the bow shorter with the heat induced reflex.

Profile looks really nice especially at full draw. It sure looks longer than 60".

[BMorv]

Man, you all don't mess around.  It's looking good!  
My trilam's un-braced profile looks just like that one, and I'm having trouble bringing it to low brace.  It keeps popping back to it's un-braced profile with the string laying flat on the handle.  I keep shortening the string but it keeps going back.  Any tips?

[Roy from Pa]

That last picture is not Tims bow. I was just showing Pat what my bows profile looks like.

Benton, it could be that your bow is still way too heavy to string up. A super heavy bow will stretch the crap out of a string. Did you get it bending at floor tiller?

[BMorv]

Thanks Roy.  You are more than likely correct.  I tillered it with the long string but I didn't take much off since I'm shooting for 65 lbs on this one. It's bending, but nothing like my 50 lb bows.  It's probably too heavy even for 65 lbs.  I just don't have a heavy bow to compare it to.

[Pat B]

Roy, I don't build many R/D style bows but that is how I like full draw to look also.

Roy, I'm thinking of making my first tri-lam this winter. Can you tell me a little more about your form? Dimensions? Thanks

[Roy from Pa]

It's a 1 inch thick oak board, 6 inches wide and 6 feet long. I bolted 1 inch angle iron down both long edges. Center post is 3.75" high, mid limb posts are 2.75" high and end posts are 5.5" high.

[perry f.]

Thanks

[Zradix]

looking forward to seeing that 62" bend.

Very nice wood, you're doing it justice.

[LeeNY]

Nice job Roy, I like watching your build a longs.

Very cool!!!  

[mikkekeswick]

Watch those sharply reflexed transitions as they make tillering harder. It would be better to have the reflexed section blend over a slightly longer area from the deflex. You have quite a sharp transition. Putting more posts on your form would allow you to have the outers less straight.
It is always good to teach others even if they only bring water...
