Title: One piece recurve.
Post by: Crooked Stic on April 28, 2023, 04:23:32 PM

New form. Did one a while back and had terrible hand shock. This one will have more preload. I am thinking 19 or 20 riser for 60 in. bow. what you all think.

I have a 60" one piece I used s 20" riser it makes a good shooting bow.  Haven't built one in years takedowns seem more popular.  I need to build some.

Post by: Crooked Stic on April 28, 2023, 06:30:03 PM

How much forward taper did you use Jess?

Title: Re: One piece recurve.
Post by: jess stuart on April 28, 2023, 06:32:53 PM

I used .002 but back then everyone wanted 60 plus pounds.  If building today's weights would go .001 or possibly. 0015.

Title: Re: One piece recurve.
Post by: Crooked Stic on April 28, 2023, 07:46:41 PM

Yeah I had an OMC design that called for .004 FT. but most were above 50 pounds.

Title: Re: One piece recurve.
Post by: jess stuart on April 28, 2023, 08:41:36 PM

I have been using less and less forward taper in my recurve limbs.  Haven't noticed any negatives so far.  The very first book I had with recurve instructions used all parallels.

Title: Re: One piece recurve.
Post by: Crooked Stic on April 28, 2023, 10:14:37 PM

Seems to me you could get by parallel and work on the width taper. I got a Black Widow that has tapers (don't know how much) looks like .002  by eye ball and is tapered from fade to tip and maybe 1/2 at the grooves. Does have carbon twill on front and another thin black lam maybe stablecore only 38@28. But my guess they got the CNC to help :dunno:

Title: Re: One piece recurve.
Post by: Mad Max on April 28, 2023, 11:40:21 PM

I have a 60" with a 20" riser---lam starts with a .005 then changes to .002

Title: Re: One piece recurve.
Post by: Kirkll on April 29, 2023, 12:10:09 AM

I've never regretted going with .001 FT on my static tip RC limbs, and drop to a par at lower draw weights. I think with 50# plus draw weights an .002 can be used without too much lateral or vertical stability issues just using glass, but anything lower i want more meat at the base of that curl to hold it stable... Nothing worse than fighting limb tracking issues... I've had some light weight bows that you had to be careful which way the string loops were flipped on a flemish loop to keep it tracking straight...

I like your limb shape Mike. I think it will do well once you find the sweet spot on the hook for your tip notchesand the right string length. What exact length you end up with, and the amount of preload is a crap shoot on a prototype one piece.

I always prefered to do my new limb shape prototyping on TD limbs so i can adjust the preload a bit with limb pad angle using an adjustable riser. I also  use different string lengths to get the things dialed in. That, and find the best tip notch location on the hook....   After i get things bending right and max performance and stability, I adjust limb butt length to hit AMO bow length, then i measure from the string back to the deepest part of the grip location at  7.25" ......

then.....  i reverse engineer to a one piece....    This gives you room for adjustments to get the max out of your limb geometry. If you aren't happy with it, you have the option of shifting the stops on your form, use different taper rates and wedges, and go again. Or worst case, build another short form with a different shape.

I wish you luck on it.... could be a winner....  Kirk

Title: Re: One piece recurve.
Post by: Crooked Stic on April 29, 2023, 07:29:20 AM

So Max sort of a built in power lam?
I have two sleds like that and one has a built in tip wedge and the power lam---Kenny called it superman. But I think they are stepper than .005. 010 maybe.
Yes sir Kirk I hate tracking issues.

Title: Re: One piece recurve.
Post by: Mad Max on April 29, 2023, 07:37:23 AM

Yes

Title: Re: One piece recurve.
Post by: Kirkll on April 29, 2023, 10:46:00 AM

I use a double ended power lam milled at 30” length for a 20” riser tip to tip on the fades. This gives you the same effect as the multi taper laminations and it’s easy to lay up. This power lam just goes on the back of the riser…

Back down in the form that is the same way I built my form.  Works great.  Looking forward to seeing a finished bow.

Title: Re: One piece recurve.
Post by: Buemaker on May 02, 2023, 08:46:54 AM

Would be interesting to see the taper rate on that Widow. You could measure the thickness on a limb 10-12 inches apart and se how much it tapers.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 02, 2023, 12:15:23 PM

Yes Jess easier for me to bend around  than into a curve.
Bue I may check the Widow today.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 02, 2023, 02:12:20 PM

The Widow is .004 FT 62 in. 38@28 but like I said carbon front and some other black thin lam in it also

Title: Re: One piece recurve.
Post by: Kirkll on May 03, 2023, 10:59:32 AM

Where are you measuring the FT at on the limb Mike?  .004 sounds extreme to me….

Title: Re: One piece recurve.
Post by: Crooked Stic on May 03, 2023, 09:18:10 PM

Measured it about mid limb. in 6 inches was 024 difference. I used to buld a OMC design that had .004. All of them was above 50. Like I said the Widow is carbon back with another thin black lam in the mix  :dunno:
Anyhow I got some done on the form and a riser profile jig made.I got a bit carried away with the bondo and had to break out the CNC sanding block  :biglaugh:

Are you going to edge band that form? or leave the plywood end grain as is?

What are you going to use to seal that form Mike?  I've been using shellac on mine because its cheap, and it holds up well over the years with a couple heavy coats.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 04, 2023, 06:24:07 PM

The form getting close. Just need to figure a stack.Got a piece maple for a riser once I get it figured out.

Post by: jess stuart on May 04, 2023, 06:45:59 PM

Looking good Mike.  A .250 stack in mine would give about 50#. Our profiles look very similar makes a very good shooting bow.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 04, 2023, 07:21:33 PM

How much forward taper Jess.
This one will be 60 in.and I am starting with a built in power lam that will 4 in. Past the fades on a 20 inch riserr .250 or .260 may be a good starting point. Rather be light on the first one and be able to shoot it than being too heavy.. .001 taper

Title: Re: One piece recurve.
Post by: jess stuart on May 04, 2023, 08:31:10 PM

Used .002 forward taper.

Title: Re: One piece recurve.
Post by: jess stuart on May 04, 2023, 09:42:11 PM

Mike I have a old Savage Deathmaster that has a similar profile that uses a .002 forward taper.  It measures .250 at the fadeout and is 57# .  Unfortunately to heavy for me.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 05, 2023, 07:57:29 PM

Okay am goin .260 stack thickest part with .001 FT Ready for dry run then one under pressure tomorrow.

Post by: JGR1269 on May 05, 2023, 08:36:30 PM

Hey Mike, I’m working on this one piece right now. I checked weight on it today strung up with my limb hooks. At roughly 61” full length it scaled at 48.36 pounds. It has .001 taper, .257 stack, 1 5/8” wide and my riser is 15 1/2” long. It’s a little bit different design than yours but hopefully it helps with your stack decision. What are you shooting for in a final weight?

Title: Re: One piece recurve.
Post by: Crooked Stic on May 05, 2023, 09:31:28 PM

45 or less. Being I have a 20 in. Riser and 60 in. bow I may want to reduce the stack.

Title: Re: One piece recurve.
Post by: jess stuart on May 05, 2023, 09:53:17 PM

Yes sir I would guess at .260 you will be over fifty.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 06, 2023, 05:37:32 PM

Okay I went with 220 stack.Had to do sligth adjustment to close a small gap at fade. First one under pressure in hotbox. and some dark blue stable maple

Are you using 1.75” materials Mike?

Title: Re: One piece recurve.
Post by: Crooked Stic on May 06, 2023, 06:10:44 PM

Yes 1.75 and with clean up will be 1.625. I did not use carbon but stablecore on the belly side because it was too short for the front. Have always put it under the front veneer. Could be better or worse ??
I will also add this wood I have been stabilizing grinds and drills the old Rutland diamondwood. I think they redone the formula on Cactus juice.

Title: Re: One piece recurve.
Post by: JGR1269 on May 06, 2023, 06:43:28 PM

I have always put Stabilkore under my back taper as well so I can’t tell you if it makes a difference or not. I’m curious to see where you end up with your stack. I took mine down to 1.5” wide today and filed in my grooves at 58”. I rechecked my weight and I’m a tick over 46# now.

Title: Re: One piece recurve.
Post by: Crooked Stic on May 06, 2023, 07:50:08 PM

This will have about 16 in. Working limb versus 14 on my TDs and the stack should be about 40  :dunno:

Well I got it all blanked out tips tapered and tillering blocks to find top limb Fade tiller Just a twidge off. I actually thought the limbs would have more hook but oh well. I am thinking the poundage will be good. Took most of the day curing riser overlay and tip overlays.But did get the overlays glued on the tips so can go with it tomorrow.

After a bit of work gonna be about [email protected] it or not this thing has quite a bit of preload  Could be the built in power lam goes about 4 in. past the fades. It took some adjustment to get it pulling straight. Maple on the belly.

Looks pretty good but not as planned. One front overlay even stabilized still porus and got a hairline crack,so a little redo. Have not used Gordons glass for awhile this is super clear am surpised.

The part about Gordon's is buy by the strip and not by the inch. This build has a 6 in. And a 10 in. Left over. About all you can do with it is tip overlays.

Title: Re: One piece recurve.
Post by: kennym on May 12, 2023, 07:58:14 PM

Yep, but if it's better glass, it's worth a few bucks per bow.  Over 20 years, $20 ain't too bad... ;)

Thats what is nice about light colored veneers... You don't see the imperfections in the glass as much. With darker veneers it shows up every flaw.

I’ve been using an auto clear coat for quite a few years now. I found a product that is pretty user friendly, absolutely clear as glass, and holds up real well after it’s cured properly…. That’s the trick…. getting it done, and keep it above 70 degrees for 36 hours before messing with it.

Btw…. This stuff is half the cost of most auto clear coats, and far superior to any epoxy clear coat like Thunderbird … that stuff yellows out with age and is NOT user friendly at all by comparison.

Hey Kirk, so is that product An acrylic urethane ? I’ve researched different products here in Canada that are auto clears. I can’t get that exact product, but it seems like there are similar clears out there that are 4:1 with the medium activator to add to it, the only options I find are gloss finish how do you knock that gloss off to become a matte finish?

I think it looks awesome Mike, bending pretty nice for my inexperience eyes!  :thumbsup:

I’ve been using an auto clear coat for quite a few years now. I found a product that is pretty user friendly, absolutely clear as glass, and holds up real well after it’s cured properly…. That’s the trick…. getting it done, and keep it above 70 degrees for 36 hours before messing with it.

Btw…. This stuff is half the cost of most auto clear coats, and far superior to any epoxy clear coat like Thunderbird … that stuff yellows out with age and is NOT user friendly at all by comparison.

Hey Kirk, so is that product An acrylic urethane ? I’ve researched different products here in Canada that are auto clears. I can’t get that exact product, but it seems like there are similar clears out there that are 4:1 with the medium activator to add to it, the only options I find are gloss finish how do you knock that gloss off to become a matte finish? Cheers Bryan

This product is also high gloss.... That's what you want too. High gloss has more solids and gives you a better finish... I spray a fine textured finish using a bit more air pressure and less material mixture, and a bit more distance from the surface when spraying to get a fine mist..... Or if you want a hand rubbed smooth as glass finish in satin. Just sand it to 400 grit, and polish it with 0000 steel wool.

Here is what's on the can, and the manufacture info.... I have no idea if its a urethane or not, but i highly doubt its acrylic.

 Is that marble wood veneers?   or what?     Kirk

Dont ya hate it when you sand past your I beam like that bro?

It's amazing what a tip wedge can do for a bow, isn't it.

Kind of defeats the purpose, but that spectra ply should hold up just fine by itself.

The one that really beat me up was shaping the strike plate on a pierce point riser.
The geometric shape is what determines the pattern of the Pearce points.

that sand past the Ibeam was almost a tomato stake desaster. Band saw blade had a mind of its own. Had the bow been more weight I would have added some on the right side. And that was 1.5 spectra so I ripped and sanded and add Ibeam to get 1.75

Nice save bro....  :clapper: :clapper:

Hey... What was the veneer material on that stabilized maple bow? kind of a yellow color with lightning bolts running through it.... Reminds me of Marble wood a lot... It's not for everyone, but i like the looks of that stuff myself.   I'm still sitting on some of that stuff i bough quite awhile ago.   Kirk
