Del - do it! I'll help you if needed. These bows are nuts....
Wizard - Thanks man, just make sure your core is flawless, no pins, no grain swirls etc....I wish I could find good enough yew here but flawless yew is a rare beast round here.
Beadman - Thanks, she sure does load up early! It is unlike any other bow I have made. The tube is get the balance between limbs at this point the left limb was just a bit stronger so instead of removing material i'm just letting it 'sweat' a bit. It depends on how bad the imbalance is but normally just a few minutes is enough.
Dictionary - Haha! What is this 'darkside' of which you speak!?

I managed to get out yesterday for a bit of flight shooting with this bow.
 Conditions weren't ideal and the bow started to show a little twist on the lower limb for some reason when I took it to full draw. I had no heat source so couldn't fix it where I was....therefore most shots were at about 23/24 inch draw. It has a heavy tillering string on it at the moment as well.
 The best shots were around 320yds.
 This gives me hope for a properly drawn arrow to go a good way further. Next weekend I will have all the small issues sorted out and will let some fly!
 The bow starts to stack at about 25 ish so there will be a good weigh gain in the last few inches. It shows little string follow even after being strung all afternoon.
 I want to plot the force/draw curve as this bow feels unlike any other I have made with very high initial tension then a definite 'let off' through the mid draw then a fairly stiff ramp up for the last few inches.
 I have high hopes for this bow.

It's the sinew that puts me off, I've got some red deer leg sinew (from Highland horn), but the prep' seemed such a pain and the fibres weren't very long. When I see the Oriental guys on youtube they have lovely long sinew.
Any pointers for decent sinew in the UK would be appreciated.

Sweeet Mike.Sounds like a real ripper!!!!!.That is unreal the overdraw your gonna get from that bow.That's putting the composites to work I'd say....lol.Gotta perform like a champ for sure.Nice bow and with not any major problems too.All natural materials too!!!!.
My composite hickory although 60" long has the same type of progession in poundage.A lot early/level off midway/then begin to ramp up to full draw.Pretty sweeet.Lately the bow has been stored in about 45% humidity a few weeks and I can tell it is performing even better than when first made.A pound or two more poundage too then of course.For hunting here it's what I want.A 52# bow performing like a higher poundage bow.I don't really know how what poundage bow it performs at really though.Somewhere in the 60#s range I'm sure.Maybe close to 70#'s.Not sure.A 600 grain arrow @ 175 fps @ 51#'s.I don't have a formula for that....lol.
Del....I've got these 12" to 16" strands I get from elk legs.Could send you a few tendons.A normal tendon will yield around 400 grains.Would a person run into a problem there?

PM sent.

Aw, good luck with the twist. Can you make a video of yourself correcting it please?

Backstrap sinew is longer... can buy cattle sinew from some places. It's expensive..

Mistakes I made when processing - rough surfaces, being impatient and pounding too hard?, pounding or ripping the sinew apart when wet
