I drew the marks on after glue up, before the clean up measuring from the edges of the glass. I can see drawing before being a good call. I drew them in, checked alignment with a string, then redrew to get the line up I have now

I don't do the marks before glue up. I was just curious.

I wait til after cleanup(or mostly cleaned up) to put any marks. I guess I'm not confident enough in all the lams and glass staying perfect thru glue up.

I pull a string thru same as you, but only use a single strand of B50. If everything lines up, then I move forward. If something is off, then I put more marks at fades and midlimb to determine which tip I need to move to make everything align.

Mr Jansen says this bow is actually 44 amo. I don't know exactly what that means despite him trying to explain to me it is the string length plus 3 inches. Well I'm making my own string so does that mean I'll have a 41 inch string? And should I measure the length of this bow from the belly or the back to get my total length. The drastic curve on the back could add some length. I'm thinking about just starting with the bow 47 inches ttt. And doing 46 ntn to see how the poundage is that way I have some wiggle room. I've heard these have some stability issues if the tips aren't a ways behind the handle. Do tall have feedback on my length issue?

Do you still have my plans where I drew out the location of the nocks?  That should give you a good idea of the location of the nocks in relation to the riser/limbs regardless of how you measure it.  If you no longer have the plans send me your email address and I will send them to you.

Yes the string is approximately 41".  If you were to measure (belly side) from one nock, around the curve of the limb straight down to the other limb and then around be the curve of the other limb to the other nock, that would be about 44". In other words, imagine if you put a string on that bow without flexing the limbs at all - that string would measure 44".

I will measure one of mine and post a picture when I get home tonight.

I looked on the computer and found the file. I feel goofy for overlooking it had a spot marked for string groove. Guess I can print that and overlay the bow on top to get the measurement. Thanks buddy for backing me up through this deal. You da man.

44 ntn measured that way. That looks good. Any chance you could measure the distance along the back of the bow ntn? I will be able to more accurately work off of that number I really appreciate your help sir. That bow is a beauty! I didn't see a post of it when i was doing my searches, I like it at least as much as your black and white one. Beautiful handle.

45 pounds at 19 inches right now. Already going much better than the last one but still way heavy.

If the weight increases 3pounds per inch that puts this at 73# at 27 in. I'm thinking I'll try to reduce the width about 1/16 on each side and trap the back 1/8th of an inch. See what that does then do some sanding on back of bow.

EwokArcher

Here is a question for you guys. I believe it a hard rule that shortening a bow will increase your draw weight. I currently have a ntn distance that is about 2 inches longer than the original bow. That also puts each tip almost 1 inch closer to being even with the handle. The original unstrung bow has the tips like 2 inches behind the handle for stability reasons. I wonder if there is any world where the set back tips on the shorter limbs would actually decrease poundage due to preload? Or would it only decrease early draw weight and increase the end draw weight. The deal is these tips are almost perpendicular to the back of the bow unstrung wo it makes me wonder.

This bow will 100% be named mosquito.  This unfortunate guy must have landed on the glue before I put it all in the form.  I'm a little disappointed I styled this bow planning on snaking the back so he will be covered.
Also glued up handle layers.

EwokArcher

Forgot to attach.

I can't for the life of me get these unstable tips under control. First of all I think figured out why my draw weights were all jacked up. I didn't uncheck the "fit to page" box before doing the original plan print so everything is all jacked up and this now is a little bit more aggressively curved than the original.
I have this top limb flippin and floppin back and forth during my draw. It now is consistently pulling to the left I have tried filing the groove crazy deep on that side I've taken off enough material on the other side that the tip is offset towards the side it is pulling to. It's crazy. Any tips?

Looks like something is out of line. is your form square?
High on Archery.

EwokArcher

As square as I can get it. I lined everything up with string before continuing. I'll go take a second look at my form.
