Here's the handle. I had a hard time trying to make the transition between handle and belly smooth and there is still a small lip if you can see. I know it's an aesthetics issue but how do you guys get rid of that?

Look at 5th pic. Fade should extend into limb. So handle doesn't pop off.

Do ya have a rounded side on your rasp or a four sided file?

Oh forgot to ask, I'm going to trap my back after rasping the belly taper tommorow. How much of the back do I leave on?

Use drawknife or rasp to make transition smooth.

DO NOT USE THE RASP TO TRAP THE BACK, just use a sanding block or a scraper and just remove enough to make the flat on the 45deg angle about 1/4" wide. Most of the back should remain

I like to pre-taper the handle on my belt sander BEFORE I glue it on to the belly of the bow.  ...and I agree that it likely should have been a bit longer to avoid the popped-off handle issues.  You can help prevent that issue with a silk or other fiber wrap that covers the transition.  Saturate the wrap in superglue or epoxy after you lay it down.

I like to do it ahead of time as well after having the difficulty smoothing the transition myself. I found if I came at it across the side angled from the center I could take down each edge and then the center easier. I also put a super thin lam on the belly to avoid singing it at first, then once the lip was real small  I put a piece of paper and used the finer side of the rounded file, if ya remember that you are not going for a straight lined angle / from the belly to the handle. A gradual slope that gets increasingly steep to the heigth of the handle you are going for is better

the reason handles pop off is that the bow bends to much in that area.as long as the fades extend past the handle you should be all right but that area needs to blwnd in with more of a radius

Bubby,
When you mean the trapped back has to be 1/4 of an inch wide, you mean the chamfer has to be a fourth of an inch wide at a constant 45 degree angle all the way along the bow (including through the handle), right?
And handles pop off because  the transition is not good?  I don't think my fades extend past the handle. What should I do?

Yes try and just chamfer the back corners, i don't think you want to big of a trap is why i said 1/4", how long is the riser that you glued on?
