Riser question

[KenH]

If a bow was designed and built as shown.... and you wanted to make a "shallow" raiser version with no arrow self, along the drawn line... what will that do to the dynamics of the bow?  If all else were equal would the draw weight remain the same?

Draw weight would probably stay the same because that looks like a fixed riser design, not bend through.

That being said, I'm not sure that a shallower riser would hold up to the pressure being placed on it due to the bows extreme design. You may find that a smaller piece of wood there would cause the bow to break at the handle.

Nice bow!

I agree Cody.  Beautiful!

Tenbrook I borrowed your photo because it gave the best view of the riser side for asking this question.  The design and lam stack I have is from another hobby builder who developed a similar bow on his own.

Try carbon reinforcing the riser.  Basing it around a CF tube or two would give it immense strength against buckling.

Now that I've seen that, I want one too.  Keep me posted about your experiment, Ken, we shoot very similar stuff.

It would work. Maddog's machete is what your describing. Problem is you will lower the bow's draw length. IE; if tenbrook's bow can be drawn to 29", a straighter bow may only be drawn to 26".

 

 

This bow is 45"ntn w/ a brace of 6-6 1/2".

He does want the curves, he doesn't want the handle or shelf.  We both shoot "horse bows" and he was looking at adapting that design for us as we do, arrow on opposite side of bow, no shelf, shot off the hand.  Well, some shoot either side, but the idea was a narrower riser to allow for that.

Will keep you in mind halfseminole.  

The first one will be a lightweight prototype anyway, so I can then use the Lam Stack Calculator to get close to the draw weight I want.
