    Funny you should mention yellow stripes. My son suggested today that it would look cool with the edges of the fins painted gold.

    That thing looks beautiful man!

    as far as correcting the fillet, I'd leave it alone. The edges of my 5.5 inch Nike Smoke fillets look horrible (didn't round them off, I guess I could go back and do it again, but I won't worry about it) If anyone has any problems with it...it's there problem, not yours

    Well, and a bandsaw, and some sandpaper, and some lathe chisels...

    Thank you for the compliment! I'm not going to sweat the imperfections. It'll look great on the pad.

    And got the decal applied. I love those vinyl decals! I had to cut the straight line where it went across the sections.

    Pardon my french, but this thing is bad ass! I love how it turned out! It has got to be the wickedest looking rocket I've built by far. I'm very very pleased with this one, including the paint. (Bet you never thought I'd say that!) I have got an H73 Black Jack with Ion Disruptor written all over it!

    I'm trying to decide on what size parachute to use. I used a 45" on my Minie Magg which weighs 62oz, and on Tank Girl which weighs 66oz. But my next size down is 36", which I used on Big Bad Burt who weighs 22oz. Ion Disruptor weighs 40oz. Which size should I use?

    What bitchin' lookin' thing! Really nice. And the satin finish, sorry I did not say, but yes, it's a cross between gloss and flat. And it makes that nose cone look like a Radome.


    I'd go with 45" unless its a really windy day.

    Yeah, I was looking around at chutes that come with kits. I noticed Madcow kits from 37 to 60 ounces come with a 36" chute. I don't think I'd go above 40 ounces with a 36" chute though.

    Thanks Jeff. I'm very happy with how it turned out. I'm still giddy from the no-problems-with-the-paint thing! LOL

    I think I'll wait and see how windy it is Saturday. If it is windy, I'll use the 36". If it's not, I'll use the 45". With the upswept fins and reinforced bottom, it should do fine on a 36", even if it lands a little hard.

    I actually started a thread about these rocks that are all over the place at Snow Ranch. Not sure if we ever figured out exactly what they are.

    I've had several comments about my homemade retention clips, so I thought I'd show step by step how I make them. I used to use brass, but lately I've been using 1/8" x 1/2" aluminum bar stock.

    I start by marking the length of the first bend, then mark a straight line with a square. Put it in the vise using the line for alignment, then make the first bend with a hammer. With a motor case in the motor mount, I mark for the next bend. When clamping it in the vise, I've found putting the mark about 1/16" above the jaws gives the best results.

    To get a clean bend, I use a large file and hammer to bend it with. I pound against the edge of the file, which bends it cleanly. Back to the rocket to mark the final cut, then cut it with a hacksaw.

    I usually drill a 3/16" hole in the clips, even though I'm using #6 machine screws, which are 1/8". I've found the larger diameter holes make it easier to screw them in place. I clean them up with the belt sander and Dremel, and voila! Positive retention! The aluminum clips and machine screws only weigh 11 grams for the pair.

    In addition to the clips, I usually make a retention plate for my HP builds. The plate is for when I use a motor adapter, in this case from 38mm to 29mm.

    I'm using 1/16" x 1-1/4" aluminum. I print out a marking guide onto cardstock, then mark the drilling locations with a center punch. I drill the screw holes with a 5/32" bit, and the center hole with a 3/4" hole saw. After drilling, I cut it to length with the bandsaw.

    I trim the corners with the bandsaw, then clean up the edges with the belt sander and Dremel. I suppose I could use this method of retention for both 38mm and 29mm motors. I don't know why I don't, other than I like little projects like this.
