An experimental warbow

(1/12) > >>

I just started a new experimental warbow.
The belly is a nice piece of Ipe, the backing a good bit of hickory.
I'm aiming for 110lbs at 30 inches.
I've glued in 5 inches of reflex but tied down at about 2/3rds along each limb to concentrate the reflex more at the tips. I'm hoping this will avoid any possible hinges near the tips and allow me to carefully reduce the width and depth of the tips to get a nice smooth typical warbow shape at brace and full draw while maximising performance for distance. I plan on leaving the handle section stiff for about 12 inches.


This is the belly stave marked out. I covered the Ipe with masking tape so I can see the lines a bit more easily.


Here the belly and backing are shaped and rounded ready for glueing. The belly stave floor tillered well so I left it as it was.

A bit hard to see but here is the belly and backing glued and bound with a rubber strip.


Here the bow is in the form. 5 inches of reflex at the tips but tied down about 2/3rds along the limb to 2 inches so the reflex is concentrated in the last part of the limb where it narrows and depth reduces most.

I should be able to take the bow out of the form on Saturday and unwrap it. I have a feeling it may be a bit of a monster but there is plenty of wood in depth and width that I can remove if necessary.

Will post more as the build progresses.

Steve,

I do actually have two nice almost black pieces of Ipe and some perfect bamboo with a view to making a record breaking flight bow. Within the time I have for bow making I have been experiementing to make a really good flight performing bow. This nice chap asked me to make him a bow like that a terribly long time ago, but I am getting worried he may now to too old to pull such a mighty bow! Would a flight record still stand if the bow were built as part of a Zimmer Frame and used a pulley system ;D?
The last bow I made worked well. Ipe with bamboo backing, out of the same piece of Ipe as this one. It could have made 110lbs but for a slight error in cleaning up through the line instead of to the line near one tip when cutting the basic tapers. Long central stiff handle with narrow relatively stiff tips making it a short bow on a long handle. It came out at 60lbs at 30 inches once I had allowed for this annoying tip hinge. The bow was outshooting others 20 to 30lbs heavier and it wasn't being pulled to full draw by a long way. This bow went to one of my brother-in-laws as a trade for a nice knife.

I took the bow out of the clamps, undid the rubber strip and cleaned it up this afternoon.
Looks nice and has about 2 inches of reflex at the tips.
There is more than enough wood there for 110lbs at 30 inches.
Bow bends quite nice and I reckon tips will be just about stiff enough once cleaned up and worked a bit.
