uh... Guys... first post?
Yes, you will need to angle your neck, or recess your bridge. How much depends on where your neck joins the body, how far your fingerboard extends over the guitar top, how thick your fingerboard plus fret wire will end up, and of course, how tall your bridge is. The process for calculating neck angle is covered in plenty of detail in Melvyn Hiscock's excellent 'Build your own Electric guitar'. It is also important to have your guitar design finalised before making any calculations - if you change one variable without altering your calculations accordingly, your guitar could end up unplayable.
If you're serious enough to invest in fancy hardware like that, the cost of the book will be insignificant, and it will save you money by preventing potentially catastrophic errors in construction.
