    Removing wood glue mistakes?

    I've got a rocket on the VAD (vehicle assembly desk) with some good fillets, but one is just terrible. Dried wood glue all over the fin, cardboard tube, etc. I tried sanding away the excess glue, but it doesn't seem to be doing anything. Is there a method to get if off without doing much damage to the tube or it's wax covering?

    Not sure of a good suggestion to fix other than sanding. But for future fillets be sure to tape off tube and fin first, apply glue then remove tape ... perfect smoothed fillets every time. There should be some pics of this technique here somewhere

    Heat, in the form of hot air from a blow drier or heat gun. Use a simple scraping tool to remove the softend glue.

    The tube doesn't have wax on it. Wood glue doesn't stick to wax.

    If you're and RC guy, a mylar iron might work to help smooth it out. Cardstock guys use them for sealing joints with previously dried glue.

    Really explore your relationship with your wife before using her iron. Jus a thought...

    LOL! way back when we first married (yeah, dinosaurs still roamed the earth..) I bought my blushing bride a 10-4 iron, deluxe with all the bells and whistles an iron could have. Two months later I screwed the pooch when I scorched the hell out of some monocote and ruined it. Still married (with a new iron), tho'....
    She made me get my own.

    There comes a point in your life that looks just like all the other points you didn't notice either.
    If I had a nickel for every dollar I spent on rockets, I'd have more rockets.
    You may have had more fun in your life than me, but the chaos was undeniable.

    I have a soldering iron, but I don't think that'll work. 700 degrees is far hotter than the flash point of cardboard...

    Might a heat gun (for paint stripping and such) work? Or even a hair dryer?

    a heat lamp will work, you really only need to warm the glue to around 150-175F to soften it.

    For water-based glues (incl a lot of "wood" glues) you can use a hair dryer. A heat gun (as used by house painters) could easily cause damage. One other idea: set it under a 100-watt bulb for a few minutes to soften the glue.

    My two cents: You may as well bite the bullet----get out your Xacto and start picking, peeling, and scraping. Maybe use a Dremel on the thick spots. Be prepared to perform repairs on nicks or gouges with stuff like CA (to soak into the basic materials) and filler.

    Just curious, though, as to how you got into this mess in the first place....did ya sneeze or something?
    In dog beers, I've only had one....
