Hey Fella's
On the Infantry bow I posted, N2HUNTIN mentioned using I-beams on the levers, so I thought I would see how that works. (Jeff is allways gettin somebody up to no good) The bow weighs 48# at 26" draw, it's 47" overal and 46" ntn. The main body is steam bent black walnut, with a hard maple belly lam and the center of the I-beam,( Ken 75 idea) and has spalted walnut for the bottom of the I-beam and grip belly lam. Flight testing with 550 grain arrows and full sized fletch was a low of 136 yards and the best was 155 yards. There is no hand shock.
I was going to I-beam the handle as well but did not because when I cord wrap the grip it would not be visible anyways. I glued the I beam maple on the limb recurves, then filed in the holes (skeletonized) and then glued on the lower plate to actually form the I-beam. The whole purpose of doing these last few bows was because I'm drawing some plans up for a mollegabet made out off strickly thin strips 1/8" to 1/4" including the grip and the levers (will post the drawings when they are done) So here this little bow, hope ya like it. Second set of pics are detail shots.

WOW! nice! wanna get rid of it? lol
-
Rich, very nice
tiller is excellent
so what is the purpose of the "I beam" tip?
-
Really like it. Now that I've seen it I feel better ;D
-
To cool Rich can't wait tell the next one.
-
dang man thats a nice bow nice to see ya not layin round on your tuckus. keep it up rich !!
-
Stunning...I love the contrast...Ima have to try some of these working faded lams
-
Very nice Rich.That is very unique.(Of course most of your bows are). God Bless
-
The tiller looks great. I like the contrast of the wood color.
-
Rich, I like the way your brain works ;D very inventive and creative
-
Thanks for the nice words. I guess I forgot to mention that the reason Jeff was kicking around the whole idea of I-beams was to get the levers/ recurves rigid but loose some weight VS: doing a solid wood area.....just seemed that an I beam that was skeletonized would be lighter than a solid lever. Also this can be glued up instead of requiring a thicker original stave/board to cut it in.
This "glued-up" part is what would fit in with the whole idea of laminating up a Mollegabet.

Cool ideas,I like it
-
I'd say you have enough wood there to narrow the tips to 1/4 inch and gain some cast.
-
I can't help thinking that the tips could be much narrower, deeper and even more skeletonized. I love the idea and it has great potential.
The Skele-tip bow over on Paleoplanet is a good benchmark for this style of bow. It set a flight record of over 350 yards.

Handsome work as always.

It's a beauty..Workmanship is awesome 8)
Thanks Leroy

Nice looking, very interesting as always.
-
Very nice bow Rich. Love the color contrast and great to see new innovative thoughts. That turned out to be a great looking bow and excellent tiller. Congratulations
-
how far down passed your ibeam did the belly lam of the recurve go down? This is a totally new thing for me, its awesome and I second the innovation notion!
How do you feel about the performance on the belly lam bows you guys have been doing as compared to more traditionally backed styles?
-
Aries @ The belly lam's are a good way to bring up the weight of a weaker bow that has a crowned back, also it will allmost "pre-tiller" a bow if you want to glue one up in a form right from the start. Ya can look at it sort of like making the lams form the belly taper of the bow limb.....and as long as ya have the long "feather-edges" on the lambs being on the compression side makes them pretty much not able to lift as they might do on the back or tension side. Also you can tweek the draw profile of the bow by what wood ya pick for the lam, how long you make it, and where on the bow you glue it up. One last thing is if you have a bow that has somewhat "flat" cast you could glue on a higher density wood (usually snappier) and gain some cast all the way through the power stroke.
Ever since Ken did that first one, I've done 4 and they seem to work very well, pretty neat actually.

Rich great work! Ur camera operator needs a vacation...LOL Thats some great looking tiller for the length to draw ratio as well. Sweet bow oh and yeah as mentioned if ur looking to get rid of it I know of a place for it ;) TTYL

just curious what glue/glues did you use on this bow?
-
o.k. ,
You and Ken haven't posted a bow in a while, almost 24 hours ;D so its time to get back in the shop. You cant keep us waiting you know.
How about the Mollegabet with slight deflex out of the grip and reflex just above the back like the Chinese Mollegabet look alike. Really narrow tips made stiff with the I Beam idea and holes if it will allow.Beams made with lightweight wood and main lam something snappy.
I know it might get you into hot water but its cold up there in Michigan and hot water can keep you warm.
-
Aries @ I use the Titebond II mostly cause it's what I have lots of and the slightly slower set & cure time I believe gives really good results.
Jeff @ You are a very BAD man......cutting thin strips today if a must know. Maybe ya needs a hobby other than gettin everybody else up to no good, that is :D Also I dont think the clan is going to like them "private" photos bein put on the internet, neither.
-
LOL that first one in the background over the front one's right shoulder looks mad as heck! =)
-
I agree, very innovative craftsmanship. This is the first time I've seen tip wedges that were narrower than the outer lams. You may inspire a few others to try this. ::) Jim
-
Might as well glue up another with a narrow strip down the back to emulate a trapped back.
-
jeff between the two of us Richs gonna be in trouble !
looks as if the first ones releaving himself and the seconds .... uh well pizzed on !
-
;D
-
Unique bow Rich. Wicked bends.
-
Now that my friend is innovation at its finest.Great job and we'll see if I can fuel the fire a bit??Seems to me some scallops would drop a bit of weight off the levers without affecting rigidity any!hehehe
-
Rich..
BUILD-A-LONG! BUIL-A-LON! BU-A-LO! B-A-L!
SORRY JUST GOT TIRED OF TYPING. But, seriously........Do a B-A-L!!!!!!!
N2
You are sick...From me, that is a compliment.

As always, God Bless
