BigFoot Sasquatch "Sweet 16" T/D Longbow

[stujay]

Nice review of a really good lookin bow!  

[katman]

Kirk, what are the advantages/disadvantages to the shorter riser and longer limbs? Performance? Stability? Besides preventing stack what are the pluses/minuses for a longer working limb? My number is coming up in a few months and curious. Great looking bow you lucky dog Rob.

[bayhunter]

Kirk are you going to have recurve limbs avaible too?

[Bjorn]

Can't wait to shoot one of those!

The biggest advantage to shorter riser/ longer limbs is you get a shorter bow for tree stand or ground blind conditions Like Rob explained in his review.

Besides extending the stacking point, The longer working limb gives a smoother draw reflected in the mid portion of the DFC chart.There are many archers that will gladly trade off some speed for less pounds per inch in the mid section of the draw. That's why a lot of guys prefer a recurve limb to a long bow. they get that feeling of a let off in poundage at about 22 inches. I'm getting that let off out of my hybrid long bow limbs without leaving too much on the table in performance.

i just took an order today for my first "Sweet 16" Sas recurve in a 62". Actually I've got several guys that have been waiting for me to get a shorter recurve going, and i think this shorter riser should do the trick. it will take a few limb lay ups and some testing to get the working limb length and placement established for different draw lengths. I may have to lay the pad angles back a touch for longer than a 30" draw  too. but i'll get her figured out in short order... so the answer is yes. I'll have em dialed in good by mid summer.  


   

Can't wait to shoot one of those!    

Bjorn, Are you going to make the Western States Rendezvous in Petaluma Ca in May?  I'm going to be there and set up a display. I should have a good selection of bows to try out. including another new long bow design called "The Flat liner".... that prototype review should be posting before too long.  

i'm a seriously busy dude right now.  

[Shinken]

That's a great lookin' TD longbow you made for Rob, Kirk II.

I look forward to learnin' about THE FLAT LINER design as well.

Shoot straight, Shinken

Kirk, how does the short riser affect the sight window?

[katman]

Looking at the pics of Rob's bow almost looks like a recurve strung at that brace. Lower brace less preload.

So tradeoff is a little less performance for more smoothness and a shorter overall length? Is that made up in the increase in draw length?

How does short riser/longlimbs effect shootability?

Thanks for being patient with me Kirk.

Nice looking bow and great review Rob.

[sticksnstones]

Righto Kirk, that makes sense. Thanks for the pictures and education on that.

Cant wait to see it buddy!  Might even have to shoot it as well, I've been known to shoot righty once in a while

No problem Gery,  You've got the right idea about a longer working limb having a bit slower arrow speed at shorter draw lengths due to more limb moving forward, which is more mass weight.

This is definitely mitigated by a longer draw length, and longer power stroke.  This is why your average production line bow that safely draws to 32" performs pretty decent at 30", and average at 28",  but dies on the vine at 26"-27". I build most my my bows "Draw length specific." to optimize performance at a specific draw lengths.

Now the part about a lower brace height having less preload isn't really much of a factor in aggressive r/d designs. Typically the amount of preload is built into the limb design in the form of reflex, and fade angle, and it isn't as critical on higher poundage bows as it is on bows 45#'s and under. a lower poundage bow will typically brace a bit higher to gain a bit tighter string though, and it helps quiet it down.

a really good example where brace height does effect preload is building a D shape long bow that draws 50 pounds at 32". This requires long sweeping reflex with longer limbs from 66-68" in total length. It would be advantageous to brace this bow at about 8" drawing 32". bracing it lower will not stop the limbs efficiently and produce hand shock. Now if you built the same bow at 50 @ 28" you could lower the brace to 6" and still have the same preload.

i hope that helps... Kirk

Wow! This explains why all the Hill threads I see are talking about 6" to 6.5" brace. Seems like most guys shooting Howard's form are drawing 25-27 inches. I draw 31.5" and I shoot a 70" Hill most of the time. I never understood why, but when I brace at the "normal height" it won't shoot for me at all.

I've never admitted it in public, but I keep mine braced between 7.5 and 7.75 inches. (I've never been brave enough to take it to 8") It's fast and quiet so I just run with it. I'm not suggesting anyone else crank up their Hill, mine is out of warranty and I accept all responsibility to anything that happens shooting it setup this way.

Not to shanghai your Sasquatch thread with Hill talk, but I learn a lot from what you post here Kirk. Thank you!

Got it, thanks so much Kirk.
If possible now I am more anxious about my upcoming build date.

the optimal brace height for any stick bow is based on its design and geometry, the archer's draw length.  there is typically a working brace height range to both observe and respect.  the bowyer can provide that data.

so far, this 58" aggressive hybrid sasquatch works well for me at a 7-1/8" brace height. it could be increased.  most 68" to 70" hill style longbows work best for me at 6-1/2" to 6-3/4" brace heights.  

as always, ymmv.
