Very interesting build.  Will be curious to see how the draw weight increases with the boo strip.   I’m always surprised how little bamboo it takes to increase draw weight.  Cool project

It’s a bow!


It’s mostly finished now.

So, for a bow made out of belly drops from a material combination and bow design I’ve never done before it ain’t too bad! Good enough to be worth finishing nice.

The tiller isn’t perfect, it’s working too hard in the inner limbs but it was all the wood I had. I didn’t get rid of the last of the glue from the glue up on the belly of the inner top limb until I got to 400 grit sanding it.

I was hoping for 35-40 at 28 and it turned out at 34@32. Again, couldn’t get any more weight from because of the thickness of the Ipe so I’m not too worried.

The actually tillering took no time at all.

I think if it was an inch shorter in each limb it would have been spot on. Really pleased that I’ve got all the information I need now to make another.

Siyah angle was spot on for 28” but not quite enough for 32”

I’ve shaved all the weight I feel comfortable removing from the tips. I could probably get some more off but I’m going to leave it as it is as I’ve ruined a couple of good bows by over thinning them. It’s nicer with a heavy arrow but think the long thin limbs cause a bit of vibration and the extra inch of unnecessary Ipe on each outer isn’t exactly helping.

Sheep horn (yes I’ve got sheep horn already) for the string bridge and nock plates.

145fps with 13gpp, couldn’t get a reading on the lighter arrows as light was fading. Not fast but not too bad.

Need to make a string but I don’t have one of the jigs for doing the conventional strings with the long loops and serving so I’ll wing it with a Flemish.

With the string, are the long loops beneficial to how the bow works? I can’t see it making any difference but I’m not 100% sure


Also, it had a twist in it from the inner tube wraps but amazing it didn’t get glued in and straightened when I took the wraps off.

You can see in the pic that I didn’t get a great reflex curve, something to remember next time

Hopefully you can see here how I shaped the siyahs

Very nicely done James.  You would be safe to shave more weight off those tips imo for even better speed.  That heel piece likely not needed at that weight.  Still decent speed at 13gpp!   Your next one will be a screamer!

So, need to double check the draw weights can’t remember it’s it’s 34 or 32lbs at 32” so this is 33lbs- Edit; it’s 34lbs at 32” so below forges are slightly off
Turns out I was short drawing by 1” yesterday. Re chronograph today in better light conditions.
420 gr (12.7gpp) 151fps
320 gr (9.7gpp) 168fps
228 gr (6.9gpp) 190fps

I think if I made the limbs 1/4” wider on the inners and an inch shorter in the outer  it would gain a good bit. As you say Dave Ive definitely got a bit too much on the heel of the siyahs but I think it looks kinda cool and I keep over thinning my tips so I’ll leave this one as is.

7gpp the hand shock is noticeable but totally manageable,the arrows is obviously too light but I could shoot them happily without worry about discomfort or damaging the bow.
It’s more that there is a lot of vibration and resonance through the bow than it hurting my joints.

The unbraced photos were taking 5 mins after shooting, it’s got a bit of set/ string follow on the upper inner.

Here’s a video of me shooting with the three arrows I tested, heaviest first.

Any feedback pointers or advice from anyone would be massively appreciated!

That turned out very nice. Sounds like you learned a lot along the way.
