ok guys, I'm very new at this and very excited!! I love seeing the great fellowship between all the Bowyers. you guys are great!. I just bought my first kit from Bingham and I have a ton of questions.for starters, I'm starting with a 60" takedown recurve and one of my questions is...When I'm designing my own riser pattern is the very center of the riser lengthwise at the deepest part of the handle? should I always draw my patterns with the center being the deepest part of the handle? more questions to follow Guys, be patient with me please...LOL
-
yes
don't change it to much
-
Good luck on your build- yes the center is generally the deepest part of the grip.

Ok, now I'm just starting to take my baby steps in all this bow building and here's another question for my riser.( my second question ever by the way since I just learned how to do this on Trad Gang) THIS IS AWESOME!! Anyway, as I said i have the Bingham kit for a TD recurve and when I put the 2" tape on my Bo Tuff glass I marked the center line lengthwise just like instructed. Once I pulled the limbs out of my form I drilled the holes using the drilling jig and for some reason the holes didn't drill on the center line I had marked previous. The one limb was a little crooked coming off the riser..Darn, so, should I mark the center line on the limb AFTER I take it out of the bow press? after I sand off the edges of glue that is?
-
You did it right. The center line goes before,glue,up.
The center line is used for everything, when your cleaning the glue off etc. Always check that you removed the same off each side.
Also those centering jigs are not absolute. You need to help it along maybe even using a shim to get it just right before drilling.

A centerline established prior to glue up isn't absolute either. As you noted, it can be less than perfect coming off the form.
I find centerlines unneeded until after glue-up, and since they can't be perfectly trusted following glue-up.... I draw them on there afterwards. To do so, I put the bow in the vise so it's level side to side, run a string weighted on its ends, from one end of the bow to the other, orienting it so that it bisects the bow blank down the middle of the riser and limbs as much as possible. Then mark it on the ends where the string sits, and drop plumb lines down from the string to the bow in a few places on each limb and mark them there. Remove the string and connect the dots with a flexible straightedge. That's your centerline.
If you DID put a centerline in your glass prior to glue up, say, in a one piece bow, this method can be used to verify its accuracy after glue-up. This method can also be used for layout/alignment of centerlines on takedowns following drilling but prior to shaping limbs.
