    Default Wrinkle bottom layer

    The bottom 1/16th maple veneer layer has wrinkles in it. Almost wavy. Anyone have an idea or experience with what went wrong? I'm questioning the amount of glue, press time. I left it in the bag with no pressure over the weekend. Could that be the problem. Any help would be grateful.

    One possible reason for wrinkles in the bottom layer of maple veneer is too much glue. On my first attempt at doing a maple layup in a Roarockit Thin Air Press vacuum bag, I used *way* too much glue, and wrinkled is how I'd describe the result. (Dirty, sticky, disgusting mess is another.) My guess is the excess glue just soaked into the wood and made it bubble up all over the place - kind of like how your fingertips get if you stay in the bathtub too long.

    You didn't give a lot of details, so your wrinkles might be due to something entirely different. What kind of glue? How did you apply it? What kind of bagging setup? Any of those might be helpful info. If you haven't already, check out roarockit.com/. They have lots of tips, tricks, how-to's and videos that might give you more answers.

    Just for the heck of it, I'm tagging @Ted in this reply. If you're really lucky, he might see the tag and respond here.

    I'm having (what I assume is) the same problem. It has happened on the last 3 boards I've made with my roarockit vacuum bag (not blaming the bag, just stating what I'm using so it might help). I tried circling the bubbled areas in the picture, but it is still hard to see. I really don't think it could be that I'm using too much glue, but who knows, maybe I need to use even less than I thought.

    Did you read about glue on the roarockit site? Understand the glue

    They have a video demonstrating how much glue:

    You're the best! I don't know how I didn't see that on their site!
