Second static recurve
Posted: Mon Jul 07, 2014 11:51 am
Hey all,
Have steamed up another red oak static recurve and backed it with linen. The bow is 62"ntn and aiming for 45lbs @ 28 inches. The tips were bent around an 8 inch radius for the first 9 inches of limb and are only asymmetric by about 1/8 to 1/4 of an inch, so they came out pretty even.
The limbs are 40mm wide at the fade and are parallel to within 9 inches of the tip where they taper in to 16mm at the nocks. The thickness goes from 10mm at the end of the fades to 8mm at the width taper and stays at 8mm the rest of the way.
Now at the tillering stage but I've hit a snag... both limbs have a bit of twist but are in opposite directions...
Here is the bow on the tillering stick with the long string on. Its pulling about 20lbs at 22 inches with maybe and inch further in the tips to go back to reach brace height.
Hard to see from the photo but the right limb is twisting away from the wall and left limb is twisting towards the wall...
My Question is which side of the limb do I remove a bit from to even them out? since the left limb is twisting towards the wall I would assume that the wall side of the limb is weaker therefore scrap the opposite side? Is that correct?
Wont progress until I get some advice as I don't want to bugger this one up!!
Cheers,
Colin
