Title: Riser glue-up questions
Post by: oldfartfarmer on September 22, 2019, 06:11:57 AM
OK this is a Bingham's Takedown Pronounced 68inch Longbow im gonna be making at 35ish#

from googling I dont see many pics of there (Bingham's) risers "finished bows" wonder if many folks build them :biglaugh:
But I see most folks Glue up there laminated wood pieces from front to back--alot of recurves pics

Im a thunkin  of Glueing up Mine side to side with a maple center 1/2 inch thick then 2 slabs of Black Palm on iether side,
my thinking is the maple is the main strength core to the brittle Black palm outsides

1-Is this a wrong way to go about it? (I know glue-lam beams run the opposite way for strength) so maybe im all wet :biglaugh:

2- Binghams drawings seem funky to me, and I can't find anywhere in the manual, how deep to cut the shelf,
do I cut to center?

when I glue up id like the Maple to show just a small amount hight wise (1/2 inch or so) at the shelf- so I need to figure out how deep im cutting the shelf and to offset the maple from center

The takedown Longbow grip,
whats the rule of thumb on adding wood thickness, for more curves? Im wanting to get away from the squarish form
in to a arched  very round look including the top, bottom ends
Im thinking of adding to the front to arch up to the top of limb hight and maybe a 1/2 inch thicker in width
so it would be 2inches thick  instead of bingham's 1 1/2 thick

Im probably moving towards a recurve riser than a longbow riser--Correct?
1-Is it the riser that makes it a longbow?

sorry for my questions,
Ive never been known to color inside the lines

Cheers
John

As far as the grip goes, make what you like and, more importantly, what's comfortable for your style of shooting.

The grip does not make the longbow a longbow.  From what little I understand (it is precious little) if the string does not contact the limb belly at rest, it's a longbow.  That's the simple version. 

If I am incorrect, I'm sure someone will be along to set us both straight.

I beam it will be stronger. Off center to the sight window side maybe 1/8 th. inside of center and cut your shelf to center. X2 on making the grip to feel good to you. I guess the true longbow grip may have been the Hill style straight maybe with a small locator throat. But not many like them so more toward what we call a recurve grip.

I would I beam back to belly and you can do anything to the riser you want if you don't change the length or pad angles.  My fave grip is a recurve grip with longbow limbs. I shoot it better and it is quieter...

Check out the grip on right on the TD plan. That's where its at for me...
