The disadvantage of that method is that the wood filler doesn't add any strength to the joint, whereas using glue does.I tried this on an old piece of bt-60 and a launch lug.
I took some wood filler, added just enough water to make it like cake frosting, put it in a zip lock bag, cut a very small hole in one corner of the bag, and squeezed gently just like I was using glue to make a fillet. It takes a while to dry, but then I sanded it with very fine sand paper and it looks great. If I knew how to affix a picture with this I'd show you how it looks.

Use Titebond Moulding and Trim Glue (TMTG)-- the stuff is great! Goes on smooth and slick, and it's thicker than regular white glue so it WILL NOT RUN around the ends of the launch lugs-- it stays where you put it and doesn't form bubbles or shrink anywhere near as much as regular white or yellow glue as it dries.Anyone have a great idea on how to keep from getting air bubbles in the launch lug fillets? I have tried everything I know with little or no luck.

I've never had to fillet twice with TMTG...OK, here is what I did. I glued on the launch lug as usual, using wood glue. Put fillets on the lug, twice as usual. Then after that was good and cured, then I used the wood filler over the wood glue.
Hope this clears up what I did.
Thanks for the input.

Lowe's or most better hardware stores... read a post recently that said Home Depot didn't carry it, but I'm not sure... if they don't they're kinda falling down on the job!Where can you get this glue?

I tried this out a few months ago based on Luke's comments. I'll never have reason to try anything else again. It works very well.Use Titebond Moulding and Trim Glue (TMTG)-- the stuff is great!

I usually use a double-glue joint with yellow glue to put the lug on the body of the rocket (since I usually use double-lugs, a shorter one 'up front' and a second in a fin fillet) and then after they've dried go back and fillet the lugs with TMTG. When it's done it looks every bit as good as epoxy fillets with none of the epoxy hassles or weight. The TMTG makes killer fin fillets as well...
Highly recommend it! OL JR![]()
Your approach works fine, and gets a good glue joint between the LL and the cardboard BT. Don't know if you know this, but both of these surfaces are usually covered with a thin plastic/"glassine" covering that inhibits how just about any adhesive gets a good hold. You should be scuffing this covering (be careful not to sand all the way into the cardboard itself) on both the LL and the BT in the area immediately around the joint, say maybe up to 1/8th inch away. This will give your glue an even better grip, whatever you use.OK, here is what I did. I glued on the launch lug as usual, using wood glue. Put fillets on the lug, twice as usual.

Ace Hardware carries it; that's where I got mine.I think I posted that about trim & molding glue not available at home depot. Looked there recently and didnt see it. Bought it at Lowes. We also have Menards around here and saw it there too. Havent been to Ace so dont know about there
I have done that, too, on occasion. It works!OK, here is what I did. I glued on the launch lug as usual, using wood glue. Put fillets on the lug, twice as usual. Then after that was good and cured, then I used the wood filler over the wood glue.
