Title: Knot problem or knot a problem. That is the question.
Post by: sleek on September 11, 2017, 02:16:17 pm

This knot will be in the last outter 1/3 of the limb. Im going for 50 pounds. 1.25"of clean grain going around it on the back. Only about half an inch of clean grain on the belly goung around it. It is not punky at all. It is 12.5 inches from the tip and will bend. Im mostly worried about compression. How do knots do in compression?

If you decide to proceed do tiller the knot to appear a bit stiffer than the rest of the limb.

Generally they are harder and consequently stiffer but less elastic.  I would have less of the wood bending in that area

Ok thanks Marc. Being towards the tip as it is that should help.

wether tis is nobler to dig it out. The potential weaknesses to suffer. The twists and turns of outrageous grain. Or take action against a sea of snakeyness....

So are you concerned with the limited amount of wood around the knot on the edge of the back?

If it has 1.25"of clean grain going around it and 12.5 inches from the tip, I would probably narrow that side until the knot is gone  and use the good 1.25".  That should be plenty that close to the tip for a 50# bow, don't you think?  (Always assuming you get all of that 1.25"...that has not always been the case for me unfortunately!)  Unless this is one of your super short bows...

Not in the least doobs. The belly is my concern.

I believe I will give it a go. It is a short bow but still longer than mist my others at 55" ttt. I will drop its poundage to 40 and see what it can do.

I don't build bows that are quite a stressed as yours but I just soak them in CA and carry on. Every so often in the tillering process I soak them again. The CA doesn't go in as far as you would think.

Sleek that sounds reasonable and do able,,but if that is the limb that goes, you can always splice on a new limb for plan B
