Rocketry Product: Dr. Zooch - Freedom 7 {Kit}
Freedom 7 Build Part 1 (2010-08-31)
The parts from the new Dr. Zooch kit - The Mercury Redstone Freedom 7 Dr. Zooch had already had the BT-60 based mercury Redstone kit. I'd built one before, it was a lot like the old version of the ... [Read More]
Freedom 7 Build Part 2 Capsule (2010-08-31)The wrap sheet has four different capsule wraps to choose from - The Freedom 7, Liberty Bell, plain Mercury Capsule and the gray and orange boilerplate version. I close the Freedom 7 skin. I didn't ... [Read More]
Freedom 7 Build Part 3 Capsule (2010-08-31)I can assume all four of the capsule wraps on the pattern sheet are the same size and would now fit the nose cone correctly. I cut out the Freedom 7 wrap but cut the glue tab a little longer than ... [Read More]
Freedom 7 Build Part 4 Capsule (2010-09-01)On the the second page (fifth paragraph) there is a line of copy left from a earlier draft of the instructions. You are reminded: "And the only painting you had to do was the black band." There is ... [Read More]
Freedom 7 Build Part 5 Capsule (2010-09-01)Before gluing on the antenna fairing, I wanted to smooth out the top of the balsa capsule. This balsa was rough. I applied a light coat of Carpenter's Wood Filler being careful not to get any on the ... [Read More]
Freedom 7 Build Part 6 Capsule (2010-09-01)The antenna fairing was centered and glued to the top of the capsule. (Not pictured) The nose fairing was formed round by pressing it into the soft heel of my hand with a pointed dowel. Some ... [Read More]
Freedom 7 Build Part 7 Tower (2010-09-02)It's your choice whether or not to round the square legs of the tower. There are three provided, 1/16" square X 1 1/4" long. They might be made of basswood, I'm not sure. To round them, I first ... [Read More]
Freedom 7 Part 8 Tower (2010-09-02)Next up, you cut a small triangle out of balsa using the triangle cut from the wrap sheet. Knock off a small bit from the triangle corners for a small gluing guide. This little triangle is your ... [Read More]
Freedom 7 Build Part 9 LES Module (2010-09-02)The ends of the LES Canister Module dowel are squared up with a sanding block. I didn't want any grain to show through the final red paint so I filled some pores with Carpenter's Wood Filler. After ... [Read More]
Freedom 7 Build Part 11 Tower (2010-09-03)Here's where I made some changes in the tower construction. I placed this assembly over the top of the capsule, dry with no glue. The angle you see in the picture is how the tower legs would sit on ... [Read More]
Freedom 7 Build Part 12 Tower (2010-09-03)The second paragraph on page four looks to be left over from the prototype model instructions. Just disregard that step. I punched three small pinholes in a piece of cardboard to hold the wires for ... [Read More]
Freedom 7 Build Part 13 Tower (2010-09-04)The best advice I can give you when making a tower is to take it slow. Double check before you make the wire cuts and be sure all is straight before moving to the next brace. If you haven't already ... [Read More]
Freedom 7 Build Part 14 Tower (2010-09-04)The diagonal braces follow the same method. Carefully measure and cut the wire. A little glue is set in the corners. Tweezers are used to set the wire into the glue drops. When the glue starts to ... [Read More]
Freedom 7 Build Part 15 Tower (2010-09-04)The lower inverted "V" support are cut and glued in place. At this point you realized how little of the red wire is left! I did have enough. But if I had made mistakes in cutting the upper struts ... [Read More]
Freedom 7 Build Part 16 Tower (2010-09-05)I probably should have done this before the tower was glued onto the capsule, but I was stuck. Dr. Zooch has you simply glue the aero- spike toothpick to the top of the LES Canister Module. I wanted ... [Read More]
Freedom 7 Build Part 17 Tower (2010-09-05)Here's that rotary punch again! It's the only way I could cut those small circles in the tops of the LES motor bell shrouds. This time to form the shrouds, I used a smaller sharpened dowel. You'll ... [Read More]
Freedom 7 Build Part 18 Tower (2010-09-05)This cut is a little tricky. You want the nozzle tab seam out of sight, facing the inside of the tower. Before cutting the tip off at the correct angle, do some dry fitting against the bottom of the ... [Read More]
Freedom 7 Build Part 19 Engine Mount (2010-09-06)I'm doing the posts in the same order as the instructions, were now up to page 6. The engine mount is pretty straight forward, I won't spend much time on this. I'd rather concentrate on the capsule, ... [Read More]
Freedom 7 Build Part 20 Body Wraps (2010-09-06)I don't do my body wraps as directed in the instructions. I've tried to use white glue on the outside edges then wrap around the body tube, but when the edges should match up it's never close enough ... [Read More]
Freedom 7 Build Part 21 Fins (2010-09-07)The fins are cut out using templates from the wrap sheet. I didn't use the supplied kit balsa, it seemed soft and wouldn't hold the sharp tapered, leading edge. I cut the fins from some harder 1/16" ... [Read More]
Freedom 7 Build Part 22 Fins (2010-09-07)I tried to save some time by gang sanding the steering vanes pieces. All were taped side by side and the taper marked with a pencil. I couldn't sand them like this, they moved around too much. I ... [Read More]
Freedom 7 Build Part 23 Fins (2010-09-08)The steering vanes were glued to the outside edge of the main fin. I used one glued fin and vane as the master. When gluing the vanes to the other fins I held them side by side to make sure the ... [Read More]
Freedom 7 Build Post 23 Fins (2010-09-08)The Mercury Redstone fin mask can be confusing. I set the fins against the printed body wrap for masking, being sure the rear under hang was against the lip of the body tube. Scotch tape was used ... [Read More]
Freedom 7 Build Part 24 Fins (2010-09-08)Here's the four finished fins after removing the tape. Be sure to sand off any paint on the root edge before gluing to the body wrap. This will be a surface mount so the joint should be strong. The ... [Read More]
Freedom 7 Build Post 25 Fins (2010-09-08)The instructions don't mention doing this but I wanted a stonger glue joint than just a surface mount for the fins. Certainly nothing new, these are Glue Rivots. Holes are punched along the fin ... [Read More]
Freedom 7 Build Part 27 FINISHED! (2010-09-09)The Dr. Zooch Freedom 7 is finished! This is another great offering from Dr. Zooch. I always find his kits to be a rewarding challenge. This BT-50 based Mercury Redstone is the same scale and about ... [Read More]
Model Profile Dr. Zooch Freedom 7 (2011-05-19)This is the Dr. Zooch BT-50 version of the Mercury Redstone Freedom 7. This smaller Redstone is around 13 1/2" tall. Currently, the blog header picture is the capsule and tower of the larger, BT-60 ... [Read More]
Mercury Redstone Family Portrait (2010-11-03)Here's all three of my Mercury Redstones, From left to right: 1. The carded Redstone just built on this blog. 2. Dr. Zooch Freedom 7 (BT-50 based mainframe) 3. Dr. Zooch ... [Read More]
Dr. Zooch Redstone Pics (2015-05-19)I got a question regarding the capsule wrap shroud on the BT-50 based Dr. Zooch Freedom 7 kit. (Picture on the left.) The picture on the right is the Dr. Zooch Mercury Redstone, BT-60 based kit. ... [Read More]
