Ed, It occurs to me that with you wanting to combine two woods to make your wand, you must be careful what woods you want to use. different woods have different properties and combining the wrong woods may cancel each other out.
May I suggest a little investigation into magickal properties of wood before proceeding? I understand the desire to associate with the sign of Aries, but for myself I would concern myself more with the properties.
Bear in mind these are my own thoughts on this, others may or may not disagree.
