When you a gluing up a riser do you put in the heat box at a higher temp than when you put it on the bow for the finally glue with the laminates (glass bow

I'm no expert, but I've done high temp, low temp, and room temp and haven't seen a problem or a difference yet.

I can't tell much diff, but the bow riser is pressed in the form on a 1 pc, and no stress on it like a strung bow in a hot car.

I have glued a couple times on risers and then glued it in a bow with no probs.

I cure my risers at a lower temp and less time because of fear of checking and have no problem with them, I think after gluing into bow and pressed the riser will post cure at the higher temp that my bow is cured.
If gluing phonolic risers i will sometimes glue one up and cure with a bow at same time but my high end exotics I won't let get that hot until glued in bow under presure

When I glue up a riser, I let it set at room temp overnight and then it gets heated when in the form of a one piece.

I heat mine at the same temp as the limb glue-up. Haven't had any problems

John at Old Master Crafters says that it is find to back into the oven at full temp after curing at full temp...
