Here is a Bamboo Maple Osage trilam pulling 140 ish at 32". Not much more to add, just thought I would share. Tiller's probably not perfect, but I am raising the white flag on it and calling it done.

Sweet jesus, 84" nock to nock.

Not unreasonable for 140#. Have you weighed it? If it comes in under 750 grams, it should be good.

Looks like a nice bending beast..

According to my digital scale it weights 2.6 lbs, or 1179.34 grams.

Thank ya. :)

Oooh. 1179 grams is heavy, but it is 140# and osage belly. Should be little or no set with those specs, being slightly overbuilt.
-
I did a bow mass calculation and came up with between 1100 and 1200 grams, because of the semi stiff mid section and elyptical tiller I allwed for about 10" stiff handle. I love the tiller shape, I bet that bow has some good distance in it.

Ya it's a pretty heavy bow, 1 3/8" wide by 1 1/4" thick in center (mike gave me the suggestion on dimensions and they were spot on, so cudos). Thank you Steve, and thank you for doing the mass theory calculation, I still haven't taken the time and figured out how to do that yet, as embarrassing as that is to admit. :)
-
Damn, that's a nice one.
Can you yank it back all the way? ;)

Nope, haha. :)

Hmmm. The mass theory is still a bit of a mystery to me as well. I'm just starting to realise its potential for performance.
I did a 120# maple backed yew warbow this summer. 78" ntn, 120#@32". It weighs 773 grams. Less than 1" of set. So, according to the mass theory, is it underbuilt? This bow's performance is amazing (not me shooting it). It has cast a 1/4# (114 gram) arrow 198 yards. Livery arrows (63 grams) 240 yards.
-
Great looking bow man! I'm slighty jealous! haha, jealous that I still haven't worked with osage :P #140 that is a monster! Nice job
-
ADB, the mass theory was more based on hunting weight bows, I have found on circular tillered bows it starts to wander off to the high side after about 70#, also as discussed in the book certain woods will tend to come in lighter, yew and cherry for instance. Your bow comes in at around 829 grams not allowing for yew wood if it is circular tillered. If I were to rewrite that chapter for heavier bows it would come in about 10% lighter. Tillering the bow for low set as you achieved will always overide predicted mass which is more of an estimated mass to arrive at close dementions anyway.
-
Thanks, Steve.
-
Daniel. Your tiller for the materials and length used is spot on dead nuts and couldn't be any better....as others suggested there should be some wallop in that one....now whos gonna shoot it?
Steve glad to hear you say that about the mass theory stuff,as I have found the same n similar things with it....

Here's some finished pics. Came out just a bit over 110 lb at 28", and 140 lb or so at 32". I made sure to taper the core this time, it is probably close to 3/8" at center and tapers down a good bit to make sure there was more belly wood at the tips than core. The finish is tru oil, the arrow pass is a mother of pearl inlay dot. The unbraced picture is just after unstringing, after it sits a minute it goes back to straight with no set.

Very nice! I really like your finishing and detail work.
-
Every bow you post is better than the last. Which is hard to do because the last few you posted have already been excellent :) I'd love to have a go with that bow to see what kind of cast it has. I bet it will really spit an arrow.
What tools do you use to taper your mid lams? Sorry if I asked you that in the past. My memory is not the greatest.

Nope, too heavy for me. It is in WI now too.

Hi
WI?
I didn`t want to see if you can pull 140#, I only wanted to see how 84" look like if somebody hold it. Do you have another 84"?
Kind regards
Andi
-
You want to see an 84" bow?
Google 'Bowyers Diary' and look at the last few posts. (85" ttt :o ) only 100# tho' ::)

WI -= Wisconsin, a state here in the US, I am assuming you are not from the states. And me pulling an 84" probably looks like a 12 year old... pulling an 84" longbow, :).

Hi
No I am from BY. Thats the abbreviation for bavaria. ;D
I think you are as tall as me (when I look at your other pics), thats why I wanted to see how that looks like. ;)
Kind regards
