Going to try my hand at a forward handle ASL. Looking for stack suggestions. Shooting for 50 - 53 lbs at 28”. 66” bow length. Plan to reflex the limbs 2 - 3”. Let me know your thoughts

Have you made a standard handle ASL? Just like that, but backwards

Poundage is kind of dependent on wood choice, glass thickness, taper rate, width, etc. Thats a lot of reflex for an ASL. Ball park, .500 give or take .030? You probably won't know until you make one for a baseline.

How long will the riser be?

How wide at the fades?

How wide at the nocks.

What will be the total thickness taper?

18” riser. 1 3/8” at the fades. 1/2” tips. .005 taper. Wasn’t planning on tip Wedges. The only asl’s I have built have been Bingham’s. I am open to all suggestions. My only have to is a recurve style medium wrist grip. I just can’t shoot the straight handle well at all.

ASL,.500” at center limb like stated. 18” riser is very long usually about 14-16” - 1” to -1/8” limbs and 7/16” tips at notches. Research ASL websites and Dick Wrightmans old pages at Howard Hill Longbowman.
It is all subjective to experience and what you want to do.

My swag at that would be 43 to 47

This thread is catching my interest I would like to make one to down the line !

Since I am not looking to re-invent the longbow I am going to rephrase the question. If you were going to build an forward handle asl reflexed longbow at 50-53 lbs how would you go about it? I believe there are a few of you out there who have done this quite well.

If your lucky, canopyboy or jsweka will chime in. As I recall they have both posted reverse handle ASL's they have made.

This may help, but looks like pbucket got part of it....

Thanks for posting that Kenny! Thats a great reference. Now I'm wondering where David Lowe went to?

pditto613 · « **Reply #11 on:** February 19, 2020, 03:34:43 AM »

Thanks Kenny. Definitely different from the Bingham version. Shorter riser, narrower and faster taper rate. Starting to see why the stack numbers were so different from my guess.

I haven't been on much lately and just saw this.

Here's how I build one:
16" riser
0.050 glass
0.005 total taper to the lams
1 1/8" width at the fadeouts, maintain this width 14" out each limb, then tapering down to 1/2" at the string grooves
My form is perfectly straight and I end up with about 1/2" of string follow after it's been braced for the first time.
If your form was straight and you wanted a 66" bow that pulled 50 - 53# at 28", I'd suggest a total stack thickness of 0.500". If you want it reflexed, I can't provide much advice because it will really depend on how much reflex.

John, do you use an asymmetrical riser?

jsweka · « **Reply #14 on:** February 20, 2020, 10:27:52 PM »

No. Everything is the same on both ends. I let the bow tell me which limb wants to be the top limb when I first get a string on it.

That’s what I was looking for. Thanks and nice bow

Canopyboy, aka Dave made this for me.

pditto613 · « **Reply #17 on:** February 23, 2020, 04:41:26 PM »

Spent last two days building my form and grinding lams. Had everything laid out to start the dry run and realized I don’t have a firehose long enough to glue up a 68” bow. Nice bow Roy

Flem · « **Reply #18 on:** February 23, 2020, 05:16:44 PM »

I'm sure someone here can help solve that dilemma. Post up a picture of what you are using for a form.

pditto613 · « **Reply #19 on:** February 24, 2020, 03:23:06 AM »

Big Jim is going to solve it when I order more fire hose
