I would rather fail at something above my means, than to succeed at something  beneath my means

With the string off I lay mine on the work table, mark with a pencil around the riser, measure up from the table to the centerline of the tip, flip it end to end and line up the riser to the pencil marks  and check again.

I have some 5/16" dowels if you need them :thumbsup:

With all that hook in it the string needs to be DEAD center.
Start the belly grove shallow and measure 10 or 15 times as you file it in. I use a 1/8" file first, then chainsaw file.
Looks  off center close to the nock, that could be the problem. :thumbsup:

Leave your tips wide starting out. I have had best luck by deepening grooves to get tracking good then  even things up by narrowing the tips to the target width. Use stablecore also. and no more than .001 forward taper. Even no taper and work side profile if the tips are too stiff..
Never had much luck sanding the strong side. And side to side lam grind needs to be dead nuts on.
I dont file any belly grooves until I get the string landing dead center every time I shoot it during the tiller process. Be sure you string is not binding giving a false reading to.

Bill Howland said that before filing string groves he would shoot the bow several times with a light weight arrow and adjust if necessary  until string was dead center and all was good.

Tillering blocks can assure you find the true center of your limb.  I find I fewer alignment issues since I have started using them.  Stabilcore and less forward taper and wider limbs are all good ideas.

Roy. I guess my English is not correct, but with string groove I mean the one on the belly side of the recurve that the string rests in. The other ones I call nock grooves.

From what I see I agree with mad max looks like near the tip is off center!! Hope you get this worked out cause it looks like its gonna be an awesome bow when finished!! I had the same issue with a Ben Pearson Hunter that I have and it took me awhile to get the confidence up enough to do it but once I did it has been fine!!

So I spent some time looking at this over the weekend and I think I messed up something while drawing the centerline. Next time I will flip the bow and check on the other side like Max said.
Now I have to glue up a new limb before this project can move forward.

Thanks all for comments and tips!

Before you make another limb...  You may want to try moving one of the limb holes over to straighten out the limb...  That way you can check how it bends and shoots before you move on...  If you don't like these limbs you could tweak and make a whole new pair...  Otherwise you are putting more effort into something that you may not be happy with...

What if you filled the alignment pin hole and drilled it again after slightly moving it over to hopefully correct the misalignment.

The thing is my alignment issue is really in the curve section and not in the first 2/3 of the limb. So the hook is actually not square  with the rest of the limb.
So I don’t see how moving the pin hole can help me with this.
