250 pounder attempt
adb:
I'd have to agree. I seriously doubt that cherry would be able to withstand 110#, especially with a narrow profile. I think it would chrysal horribly.
I've also made several backed cherry bows, and they've all been <50#, with wide & flat limbs.
RyanY:
Well I don't know what to tell you guys. I just measured the bow this morning and it was more at around 105#@32" plus I weighed myself and it gave an accurate reading for that. The bow started out as 1/4"hickory backing, 1/4" purpleheart core, and 1/2" cherry belly. I thought cherry wouldn't be strong enough for it too but It hasn't chrysaled bad at all. The bow has taken around two inches of set. Also I made a string for it and it's actually 74" ntn. I'll try and make a graph like alanesq.
Yewboy - I was kidding when I said it was easy in that video. It is by no means easy to draw but considering the bow I have been drawing it's a dream.
alanesq - Thanks for posting that graph. Your warbow buildalong page is the reason I had the confidence to start making them.
RyanY:
Well I just finished up trying to make a graph like the one alanesq showed. I did two inch increments from 12-26". I was having a rough time holding it steady at the longer draw lengths but I noticed that it started to stack a bit in the longer draw. I plotted it in an x,y scatter and added an exponential trend line to account for stacking. I plugged 32" into the trend line equation and came up with 108.8#. Its not the most accurate reading in the world but that's all I got. I don't really have any other way of measuring the draw weight. Anyways, I'll try and see if I can take some pics with my mom's camera to show better pics of the bow and I'll also take some of my last glue up of hickory, purpleheart, and white oak.
An aside - The color of this cherry very closely resembles yew heartwood so a hickory/ash/maple backed cherry could look a lot like a fake yew bow and with some added perry reflex could be a sweet shooter depending on design.
Ian.:
Taking a note from Alan white oak and white ash will make a heavy weight bow up to as he has proved 160lb I wouldn't be using hickory or purpleheart on anything that is, no offence just a weight trainer.
alanesq:
ryoon4690 : You need to do the same for your other bow now and then you may see why one is harder to draw than the other
it may be your other bow is heavier to draw at the start but goes up slower so reaching the same end draw weight
Or it could be just a matter of an extra 5lb making all the difference if you are close to the max you can draw - I find that a 100lb bow and a 120lb bow can feel about the same to draw but just go slightly beyond your limit and you can't draw it at all
