Top Form Question

[ChristopherO]

As I get the time I've been putting together a recurve form.  The bottom portion of the form, the important one, is very clean and uniform.  The top form, though, is not exact due to some router issues.  It is close but there may be 1/8" varience here and there, especially near the tips where it is tighter on one side than the other.  Plus, some voids were created where the router plate loosened allowing the pattern bit to drop and dig. Is this such a big deal considering that the air hose will be filling in the gaps once inflated?
BTW, this is a 1 3/4" wide form, should I look for an inch and a half diameter hose or a 2" hose?  
As this is my first any advice is welcome.  Thanks.

I just cut my top part with a band saw and then sand down to the line with a 3 inch drum sander, its square with the sides but does have some small dips,the fire hose fills in the voids, the bottom I cut with a band saw and then screw on my  template and use my router with pattern bit,I did have a couple of small gouges that I had to bondo in to make bottom perfect, I then glued a .050 piece of black glass over the plywood, my bows are perfect off of the form . I have both 1 3/4 and 1 1/2 inch forms. I bought my fire hose and plugs from Binghams Projects. KennyM has a form build along on his web site.
