ASL ?

[kennym]

John, I think one of those hill charts is from you on your bows?

Hey forward handle there is great mystery with building Asl's and with good reason. They are different due to their narrow width, length and high wood to glass ratio. String alignment in it's own right can be a challenge. For your first experience for a 68" bow  I would suggest a 14" handle 1 1/8 wide at the fades, .40 back glass and .50 belly, 5 thousands overall taper and a form with 1.25 backset which will yield a 3/4 backset bow. It will be a fine shooting bow. Deeper design features can easily  yield bows in excess of 180 fps @ 10gpp but thats heavily guarded LOL

Thanks John good info that's a beautiful bend you have on your design I like it   

[Forwardhandle]

Thanks Charles I posted same time as you , let me ask you this when you put your reflex or back set are you putting any reflex out of the fades or are you putting it in mid to outers ? & again thanks every body for the help it's greatly appreciated I'm learning a lot even though I'm slow in the head

Ritchie, you got all the straight and narrow guy's coming out of the woodwork, or would that be the Hill's

Kenny - You're right.  That list does have some of my bows on it from back when I use to use 0.002 overall taper.  Those had more bend towards the riser relative to the outer portions of the limbs.  0.005 taper gives a better bend over the entire length.

 For your first attempt @ 5 thousands taper I would reccomend an even reflex throughout the form. With higher taper rates you can favor reflex in the mid to outer third. (I would also add a 3-4" 50 thousand glass tip wedge) I just scrolled up and saw you draw 31" ?

[Forwardhandle]

Thank you Sir , I originaly didn't relies these bows take as much set as they do seems these are Ken to self bows of sorts , so my feeble brain started thinking last night why not make them similar to how a reflex caul for a self bow would be made, I'm sure all this has been done before not much new in archery designs for a few thousand years....lol  but here are my thoughts for opinions in the pic the short design templet is strait tell the last 13 1/2 " where it progressively ascends to 2" back set I figure in the design 14" riser using Kenny's super lam would give me Aprox 3" exstention  on the fades to compensate for the additional Pressure of the reflex minimizing set in the the fade area with the reflex in the less stressed part of the outer limb & tip wedge thinking it will hold most of it, all of this is adjustable but a concept at this point it could be adjusted with less reflex but I'm thinking the design would give me a little better string angle at the longer draw , what do you guys think ? I'm no design theorist more a hands on kind of guy ?

[Forwardhandle]

Or in this version is 68 ntn is a strait line taper from center of the riser to 1 1/4 back set at the knock leaving a 2 " strait section neutral out of the fade ?

Ritchie - you're thinking too much for me.  I gotta think too hard while I'm at work, so I like to keep it simple when it comes to building bows 

[Forwardhandle]

Lol I'm racking my brain on a new design but I think I got it worked out on the next lay up ,I'm just trying to save my self from making a bunch of forms , sorry for the stress 

[Forwardhandle]

At the risk of giving John a head ache  I got my final reflex worked out it drops 1/8 " every 4.5 " to 18" then progressively curves to 1.25 " so if I get 3/4"'set It should keep me positive ahead of the handle I think  I will cut it out and smooth it up & get to work on the form thanks for all the help Fellas !

Watching this closely as im really wanting to start building asl's. Will be interesting how the reflex design pans out. Personally ive been a fan of string follow but that could just have been that the backset ones ive shot werent a good fit for me.

[Forwardhandle]

I dont know this is the thread to watch Im just bumbeling my way threw it 

[Bvas]

Ahh, ya might as well stick with what ya know and throw some deflex in it as well

[Forwardhandle]

No fun sticking to what you know Brad there is a twist comming I think you will like 

[Bvas]

I like twists.

Maple or cinnamon

[Forwardhandle]

Defiantly some maple in the mix

I’ve made and played with a bunch of different options for an ASL.  Funny thing is, they all shoot well.  I have run some chrono on arrows and the difference wasn’t enough to think about, in fact I can’t remember what they were and my chrono isn’t working now.  UGH.  I didn’t go and test a bunch of arrow differences, I just used my hunting set-up so basically 45-50# bows and 600 gr arrows.

What I settled on is a bunch of reflex-a couple 2-3 inches, 1 1/8 at the fades, 14” riser, and a pretty high rate of taper.  8-10 thou taper total, but I change this based on a draw length or outlier issues. I do add a wedge, but not always.. 1/2” wide at the nocks, or a tad less. What I’ve found is less vibration with more taper, and the big time reflex makes the arrow really pop off the bow. I am not a string follow bow fan, I always feel the release is soft and I haven’t found any gain in anything else. Not even noise. I shoot some string follow, just not my favorite. Even when I make a reverse handle ASL variation I keep my same limb reflex arc. Unless someone wants a different profile, because they are all custom after all right!

Thanks Matt you just confirmed what I was thinking & planning with the exception Im using .006 taper for my 31" draw you said a lot in your post that I appreciate ! Matt how far are you off setting your riser if you are ?
