Bamboo belly pyramid

Bamboo belly pyramid

This bow started as a “normal” bamboo backed ipe pyramid bow. I made it for someone who wanted a light bow for target shooting but when I finished it he suddenly backed out. I never shot it really because it was only 35 pounds or something so it just gathered dust on my bow rack.

Then I read somewhere that bamboo was a good belly wood also so then I figured it would be nice to try that on an existing bow! I quickly flattened the ipe belly of the existing pyramid and flattened a piece of bamboo with my draw knife.

I decided to blend the bamboo belly into the fades at the handle. I cut the bamboo in two halves and pre-formed the fade areas with dry heat over and old can which happend to have an acceptable radius

Glued the two pieces of bamboo on with titebond and some clams and sanded the bow smooth the next week. When I first tried to brace the bow I was shocked! It had gained so much draw weight that I could not get it to bend! This was a problem because you can’t really scrape much of the bamboo belly oops!
I decided to narrow the bow as much as possible to reduce the weight and aso trapped the back to lose some more weight.

I now had a very slender but heavy bow! It measured about 70 pounds at 28 inches and was extremely fast! This was a fun experiment and a lesson learnt: bamboo is great belly wood but keep it as thin as possible;-)

Bamboo backed ipe mollegabet

Bamboo backed ipe molly

This was the first bow I made for the purpose of flight shooting. I read that both mollegabets and reflex/deflex bows are especially suited for flight shooting because they are usually quite fast (if built right) and also shoot pretty smooth.

I decided on a short combination of both models and started off by glueing ash levers to the tips using a curved form so I could get the reflex in.

This was done to two separate limbs which I then glued to the preshaped handle. The top of the handle was shaped to provide the deflex. Quite hard to get this right with only hand tools!
This worked pretty good so after drying and cleaning up a bit I added the backing and the powerlam and started the tiller.

After tillering I then started the process of thinning the tips so the bow would actually shoot as fast as possible. This turned out to be a nightmare because the thinner the tips got the more unstable they get! It worked out in the end and I got to shoot it to 260 meters with a 350 grain flight arrow. (Which is way too heavy for a flight arrow but I did not know at the time)

I later shot this bow using a 27 inch arrow and broke it. Drawing it beyond 26 was a little too much haha!
