Chris/Germany Posted November 18, 2006 Share Posted November 18, 2006 Hy guys, back on the block! Badly infected by the "jet-bug" I started my next project this week, this time a RF-4E/F in a stunning paintsheme. Surely this bird will be a cutaway ( what else) with massive cutaway-areas even down to the engines! ..................and yes, the engine will work ( means starboard J-79 compressor wheels will work) step 1: cutaway opening of the starboard fuselge is removed / milled out. As you can see the opening goes from near the jet-intake to the aft fuselage shortly before the vertical stab...................lots of interior and technical stuff in this beast ( am I nuts ) Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 18, 2006 Author Share Posted November 18, 2006 next step: construction of the J-79 powerplant. Unfortunately this kit has no engines so...............scratchbuilders delight. A plastic tube in right diameter was used for this, a little motor ( fits perfectly) is inserted, compressor wheels, handmade from aluminium, are mounted on a brass axle. The front-end will be inserted into the engine-intake / kit part which is already mounted on the mainframe , so ( if it works right) the whole thing can be inserted/ removed, this is planned for better handling while filling this bird with all its ribs and frames.

Chris/Germany Posted November 18, 2006 Author Share Posted November 18, 2006 back end of the powerplant is mounted ( kit-part) for a test fit into the right fuselgae half. Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 18, 2006 Author Share Posted November 18, 2006 front end / engine intake is original kit part, mounted on its spar Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 18, 2006 Author Share Posted November 18, 2006 test fit of engine: inserted into the intake, fits like a glove! Most trickiest part of this work is to get the compressor wheels mounted exactly on the axle and the motor to get the thing work without too many vibrations. electrical stuff done, so the "interior-party" can start to be continued, enjoy Chris "the ripper" Link to comment Share on other sites More sharing options...
Jens Posted November 18, 2006 Share Posted November 18, 2006 WOW stunning as usual Chris!!!! Cheers mate..! Link to comment Share on other sites More sharing options...
AndyB Posted November 18, 2006 Share Posted November 18, 2006 You sir, are a very sick puppy Why not go the whole hog and fuel it up..... Seriously though, thats a very neat piece of work. How did you get the compressor blades to align perfectly. (I have trouble getting three prop blades aligned properly ) Link to comment Share on other sites More sharing options...
KOTR Posted November 18, 2006 Share Posted November 18, 2006 The Ripper strikes again! A tremendous start, but there's a massive fault: I miss the static flow directing blades inside the engine Just joking, will be interesting to see what it will all contain Link to comment Share on other sites More sharing options...
Hacker Posted November 18, 2006 Share Posted November 18, 2006 Good Lord!!! The ripper strikes again!!!! When will this maddeness end???? On a more serious side an interesting development here. A worth chanellege for a man of your talents Looking forward to seeing more. Hacker Link to comment Share on other sites More sharing options...
Menelaos Posted November 19, 2006 Share Posted November 19, 2006 ---------------------------------- MAY DAY, MAY DAY!!! say Chris is that the newer Kit or the older one? Link to comment Share on other sites More sharing options...
LSP_Matt Posted November 19, 2006 Share Posted November 19, 2006 Hi Chris...great work like all have said Questions: How did you make the compressor blades so they have such a uniform stagger?...that is, the blades on the one disc. What holds the compressor blades to the shaft to keep them spinning evenly relative to each other? and What works as a spacer between the compressor blades to kepp them from banging into each other? It looks spectacular Cheers Matty Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 19, 2006 Author Share Posted November 19, 2006 Thanx for your nice comments guys, I knew you´ll like it! Update: starboard-engine intake modified ´cause the engine-cutaway will include intake area of the J-79, done by simple plastic sheet ( although a bit tricky to bend) Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 19, 2006 Author Share Posted November 19, 2006 je intake, outside Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 19, 2006 Author Share Posted November 19, 2006 testfit.................the starboard fuselage-half is now glued to the kits belly/main-wing part to give the fuselage a bit of strengh while building the ribs and spars, to prevent from any wrong shapes and tensions when fuselage halfes are glued together Link to comment Share on other sites More sharing options...
Chris/Germany Posted November 19, 2006 Author Share Posted November 19, 2006 interior-party begins: filling the intake area with wires, drains and so on.......same thing as with the Tonka: always a bit like building a "ship-in a bottle", from inside to outside...................
