I put a string on after gluing tips overlays. I decided starting with a first set of string groove for a 61” bow. Hoping to add grooves further out on the curve later.
The bottom limb was twisting to the right.
So I started filling the left side of this limb and the tip groove on the right side. It did improve things but the limb is still not tracking correctly. Now it got me doubting myself.
Is this the right way to correct the twist or do you guys have a better way to do it?
Thanks,
Sam

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

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:

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.

Now I have to glue up a new limb before this project can move forward.
Thanks all for comments and tips!

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!

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.

It’s just another glue up. Like flem I am not going to film the glue up process! I only take pictures once it’s all done:

I was away for a few days last week and somehow contracted Covid. Luckily I am the only person sick in my family, but down side is I have been quarantining in the bedroom for the past 5 days. I only have mild symptoms so I feel pretty lucky, I can keep working from home. I am mostly just feeling tired and my brain is slow(er!).
Probably not going to be back in the shop before end of next week at the earliest.

A good many people in my little community have had it with no issues. ;)

Finally made some progress on this prototype today. Year end work took all my free time and I must say I took my time before going back at it this month.
My big question was how to align a new limb on the riser. I found the solution in the kitchen:
