Started a new tri-lam and hoping this video comes out.

68", mild R/D, Hickory backing, walnut core and osage belly.

Let me know your thoughts on the tillering.

Click on the picture to see the video. Sorry for all the movement. It's hard to hold the phone and pull to the right draw length while keeping the bow in the middle of the frame. It's a photobucket video.


   

Not looking too shabby...

Worked slow and easy on it today. I'm only up to a 20" draw so far. Been pulling it atleast 50 times per inch from 14" to 20" with each scraping.

It seems to get old doing it this way, but I plan on shooting this one for a few day before jumping on a boo backed one.

30 times is plenty.

Can we say better safe than sorry. Remember, my last build KA-BOOM!!!!

Anyway, now I'll bring everyone up to where I am now.

Here is the form I made to build this bow.



Here it is with the bow glued together. Just waiting for it to set.



Fitted the handle and clamped it together after gluing.



Here it is ready for the long string.



After scraping and sanding alot here it is with the first short brace.

Wasn't real happy with the way i had dressed the handle fades into the limbs, so I did a little extra work on them.



After all day of scraping and pulling this is what it looks like now at 8-1/4" brace.



The video in the first post is how it's drawing to 20" and where I am at this point.

Got a few orders to get out tomorrow. Hopefully I can get back on it later in the afternoon.

That looks mean just sitting their braced up. I'm going to have to try one of these someday.

Looks pretty go so far to me Troy.  Is it taking any set yet?  I have only tillered a couple of D/R all wood bows. I had trouble deciding when to get the mid to outer limb bending more.

It has taken a little set. That was to be expected. I'll be able to tell more in the morning.

When I took my lunch break I unstrung the bow and set it on the work table belly side down. At that time the handle was approx 3/8" off the table. After lunch, (approx 30 minutes) the handle was only about 3/16" off the able.

This evening when I quit the handle was again about 3/8" off the table. I'll see what it is in the morning.

Forgot to say I work from mid limb to tip to start with when tillering. For me it helps prevent hinging at the fadeouts. Once I have the mid to tip part of the limb bending some I'll slowly work back to the fades while still working on the rest of the limb at the same time.

Just checked the bow this morning and with the belly of the bow on the table. The handle section has dropped back to approx 3/16" off the table. So I guess that means the limbs has only taken about 3/16" set so far. When I first unstung it yesterday evening the handle was approx 3/8" off the table.

Odd that it we nt up and down while sitting there!

Could it be due to humidity changes?

The more I read of tri lam builds here the closer i get to the precipice!  Maybe i'll start with a bi-lam.

Not really Mike,

You should see my wife's bow. When it's first unstring it looks like it has 2-1/2" of string follow. Within a couple hours the limbs will relax and it only has about 1" of string follow.

It nothing new to me, I expect it.

A lot of wooden bows react that way after being strung, tillered, or even shot. It just takes a little while for them to creep back to normal.

Found a little time to continue working on the new bow.

Here is a video of it, as it looked this evening after being worked through 27" draw. I hope to get time to work it through 28" maybe 29" tomorrow.

This is how it looks braced at 7-1/4"



Here it is right after unbracing.

Your tiller is ridiculously clean and spot on.

Forgot to add that the bow is now 64". Had to cut it down after not making weight.

It looks a little flat just outside of the riser ends to me, Troy.

agree with Roy. you need to get those near-handle areas moving a little more. I'd like to see a smidge more movement near the nocks, too. spreading the bend over as much working length as possible helps bows live longer. mid-limbs working awfully hard right now.
