Howdy

I just started making bread and I am looking for a way to sift out the bran from my flour.  My first batch was pathetic but my second loaf showed some promise.  The wheat flower just doesnt  seem to want to rise enough.  I am milling hard red winter wheat and so far no luck at getting the bran out.  I really have no idea what I am doing so any advice is appreciated.   I am using an old recipe from my grandmother.

Thanks
