Tillering warbow with reflex

Shift the string across at the nocks , maybe clamp the grip or put a thin wedge under it. You've got to for ce it to do what you want.
Lots of small corrections can make all the difference and once it's back to about brace it will be easier to hold it in line.
Leave the tips full width and stick a scrap of wood on the back at eah tip to cut a groove in for a nock. This maximises your lateral string adjustment.
Persevere now and it will be ok later on.

The tips are 20mm wide and even with the string loops on opposite edges of the tips the centre still falls off the side of the handle.   It gets worse at brace as well.  I wouldn't mind so much but it's now so offset that it's flipping constantly on the tiller.

I might have to do what you said and clamp it flat on the tiller, but that will require building a new tiller setup as I can't do that on my current one.  Laminate bows are looking so tempting right now  >:D

The tillering string is just an extra long bowstring, from about a million strands of B50.  I'll shorten it up once I've got the left limb a bit weaker and see where I am!

Good point about the middle, you always want to get that really bending last. Or at least I do. I kinda meant the "fade", but you have a good point too. I usually tiller the bow from the tips outward kinda, but mostly just look for areas that are bending too much or too little. B50 is stretchy, and imo sucks as a bowstring and definitely a tillering string, when the weight is higher. What works great is some 550 paracord, as there is like no stretch and you can just tie it in a normal knot without worrying about it breaking. I by mine at lowes for 8 bucks for about 50 feet or so. Fast flight would make a better tiller string as well. And I am thinking like abd, the pop was probably just the string popping out (did the string come off at the same time of the pop?). Well it may of just popped out a little bit and make a sound without coming fully out, I have had it made noises before. I think the best thing to do in this situation, if you can't clamp it down, is to get a mirror and lay it horizontally on the floor, and tiller the bow by stepping on the string and pulling up while looking at the mirror. You have to be careful not to hurt your back while tillering heavy bows like this, but other than that, I think it works great as you can hold the bow firmly in your hands and keep it from flipping over. When you get it up to a 6" brace (if you floor tiller it far enough and good enough you can go right from floor tillering to a 6" brace, but it takes a bit of practice and sometimes you might whip the tips if you don't get the full limb bending.)

That doesn't make sense to me...
If it's flipping one way, then the string needs pushing to the other side at both tips.
E.G. Facing the bow, with it's back uppermost, pulling down on the string (say there's a wall bahind the bow). If the tips are coming towards you instead of straight down. Then the string needs to be pusshed to the back edge of the nock on both tips, towards the wall. This will move the string line to the wall side of centre encouraging the tips to move towards the wall rather than towards you.
If you've moved the loops to opposite edges, then the string line at the middle of the bow it's the same as if the loops were both dead centre as the string is running diagonally across (like a bow with side nocks).
(or maybe there's just a breakdown of communication here...)

WillS:
I think I must have missed something fundamental when learning how to make a bow. 

This extra wide piece of seasoned ash, which started with 3 inches of reflex now has 3 inches of string follow, which equates to it having taken 6 inches of set.  It's not been pulled anywhere near the intended draw-weight, and has only come back to about 18 inches so far. 

To make matters more annoying, the lateral bend gets worse each time the bow is braced (although I've never even got it to a brace of more than 2 inches yet) and is now pretty much unworkable as even with the string loops as far across as possible on both sides the string is still nowhere near the handle anymore.  It doesn't make any sense to me!  I've gone slowly, and left plenty of room for mistakes.  The tillering was slow and gentle and like I said, I never went beyond the intended draw weight.  I haven't even reached it yet!
