Is this too radical?

[Longcruise]

  Cruise  -  Thats pretty much what I'm going for.

Shredd, my thoughts were to start a conversation about those type considerations.

  10-4...  I am not really familiar with that style bow but that's what I was guessing yours would look like with with 12* at the fades and 60" to 64"...

I'm looking for 60 to 62".  I redid it so the pic below shows the old rendition on the right and a newer rendition on the left.  The one on the left is more like B-JS design (thanks for putting that up).  More of a uniform arc that extends 2.25" ahead of the handle which should allow tweaking via width, frontal profile and thickness taper to behave fairly uniformly along it;s length.  That would be for starters with more tweaks later if they might prove to be beneficial.

I have an RD that is fairly mild and I'm looking to build something a bit more speedy that will have more preload.  The mild design is certainly no dog but is quick and well mannered.  This new one is looking to be a little quicker without being too ill mannered.

[Shredd]

  I heard those reflexed R/D bows are supposed to be fast but did not ever see any speed numbers on them other than the wtt contest... And who knows whether those bows were just built for speed or to last and shoot well also...  If not built right I heard they can be floppy...

If you measure along the curve how long is one limb from end of fadeout to string notch?

23.5 Inches.  Which would make about a 64" bow.  That is not the target however.  The actual target would be for a 60" bow and will call for a small adjustment to the drawing.

[Crooked Stic]

You prolly need to go ahead and build one with not too much FT and let us know 

[Shredd]

If you want Fast, Bue makes a fast bow...  You might want to pick that guy's brain...   

  Bue...  Are you familiar with or have you made any of these R/D bows that are reflexed at brace??  What are your feelings and thoughts on them??  That question goes out to everyone else out there also...

  Kenny makes a fast bow also...  That last bow he posted looks good and has a decent bit of reflex in the limbs...  Kenny did you shoot that one through the chrony??  What are the numbers??

I wanna learn from this thread that the Cruiser posted also...  I always did like the look of the Shrew but that is a short bow and I can see how having those reflex limbs could be good for a bow that size...

[B-JS]

My 54" is pretty reflexed at brace.
It's fast an efficient.
Don't have numbers (because i have no Shooting Mashine to make accurate measurements), but everybody, that has one is satisfied.
But the 60" with the serious preload is even faster.

[Longcruise]

Is the bottom pic the 60"?

[B-JS]

No. That's both two (LH and RH) 54" Strung and unstrung.
The 60" is the bow i posted before.

[Longcruise]

Here's the mod for a 60".

And for Shredd.

[williwaw]

what is the purpose of the deflex with a glass bow? I understand the deflex in a R/D wood design is helpful to reduce stress, but that does not seem necessary with glass.

[B-JS]

Build a bow without and you'll know.
One big issue in a design without deflex is handshock.

[Buemaker]

Many opinions on this, but you do not need the nocks to be way in front of back of handle in order to make a fast stable bow. I do not make these short RD bows with a lot of recurve at brace. They do not seem to be that fast. The one pictured is a 66 inch ntn with nocks in line with back of handle. Handle between fadeouts are 22 inches, limb lenght from tip of fades to nocks are 22 inches. Many say a 66 inch bow is too long to handle in the woods, but what the heck it is only three inches at both ends compared to a 60 inch. The last time I made this model shot trough a chrony from a shooting machine, 55 pound bow at 28 inch draw with a arrow 9,75 grain pr pound the speed was 192 feet. The one that shot 192 feet had a 3/4 inch shorter handle and the reverse taper a bit shorter at the tips. I will test this new one when I get it done. I do not hazzle with Carbon, wood and glass is good enough for me.

[Longcruise]

Very informative Bue.   

[Shredd]

Bue how wide are your limbs at the fades and the nocks?? Do you have a side view of that bow unbraced??  I suspect your bow is shooting 188 to 189 fps @10gpp...  I would like to get my r/d bow up to that speed...   I seem to hit the wall at 184 to 186...  You were talking about limb length... What are your feelings on that??

[Buemaker]

Shredd, here you go. Width at end of fadeout is 34mm/1,34» and a straight taper to 1/2» just before nocks. I like long risers and shorter limbs. This one have a 22» riser and 22» limbs.

[Roy from Pa]

Nice Bue and a longer riser with short limbs are faster than long limbs...

My old bear take down, the riser and limbs are pretty much the same length and it smokes arrows.

Bue
thanks for your observations about deflex.
Are the full draw and braced pics you posted yesterday in the "what did you do today" thread the same bow as the unbraced bow pic above?

[Buemaker]

Yes, the same bow.
