That is an absolutely incredible bow Simson.

Like Mike said sapwood seems fine. As mentioned the main trouble is de-lamination of sap and hart wood. I only use the sapwood if it is a nice yellow colour, like you mentioned they can rot when seasoning, well its more the sapwood that gets the mold really.

Your bow rocks! I love what you did with the sapwood at the handle.

Simson,

I am interested in making my own takedown sleeves. What  was the outside diameter in milimeters of  pipe you started with this time and what would use next time?  I want to get round pipe fit it in each other and pres it  in a vice till it is oval shaped.

I love your bow and still have some laburnum billets, I hope it turns out half as nice as your bow

This is a really great bow. I know laburnum wood looks way more beautiful in nature than on pics cause of the light-breaking effect. great work, nice pics as well.

This are the tools for hollow limb design, followed by sandpaper rolled over sticks with matching diameter:





Here is a quick sketch of the cross section it is almost a bit more of a third of circle



and the pipes I used for the sleeves, the outer one had a diameter of 40 mm and is 1,5 mm thick - the inner tube is matching in diameter. Put both parts together and clamp it in your vice you will get the oval shape in the pic. One tip: make the iner tube a little bit smaller in diameter (sanding) so that it goes really easy in and out, before clamping! Next time I will use about 36 mm diameter for the outer tube and will get a more egg shape cross section.
