Things get real interesting when you add smooth on to the lams.. I always pull the glass and lams down with strapping tape. First Use a clamp to hold riser in place, crookedstick uses a built in clamp system on his form, it is what I should have on my form. Like Snapper said do a dry run to make sure the hose pushes the parts down tight, if your tapers are too thick then you will not make the bend up the riser easily. KennyM showed us how he glues on a lam stop to the top of riser, I do this on all my longbow builds. It only keeps the lams from riding up the ramp.
