Rainer Hoffmann Posted October 6, 2016 Author Share Posted October 6, 2016 Amazing quality. Question, have you drawn the template up on a PC/laptop for the 19 guide vanes and then printed it off, or did you hand draw it? So neat. I drew the template in Illustrator. It has a very handy tool for such a task. You just draw a line, specify an angle and the number of lines you want to evenly distribute around a circle and Illustrator does the rest. In this case it was 360 deg / 19 to distribute the 19 lines along a full circle. I did the same for the 30 first stage rotor blades (360 deg / 30). Piece of cake!

Ironwing Posted October 7, 2016 Share Posted October 7, 2016 Rainer, Super precision and clean execution. You don't need a lathe. That's just a lovely piece if work...Did you turn the the parts in a Dremel? Rainer Hoffmann 1 Link to comment Share on other sites More sharing options...

That's just a lovely piece if work...Did you turn the the parts in a Dremel? Goeff, I turned only the inlet cone on a power drill (my big old Metabo power drill, that is). The outer casings were not turned. They are just styrene strips that I "persuaded" to adopt a circular form... Cheers Rainer Link to comment Share on other sites More sharing options...

Rainer Hoffmann Posted November 14, 2016 Author Share Posted November 14, 2016 (edited) Dear fellow modellers, while you guys had a good time in Telford I did some serious modelling I built the last turbine stage, the turbine casing, the exit cone and the afterburner fuel manifold. My information on this part of the engine is sketchy at best, so ther is a lot of artistic licence involved. However, not much will be seen of this assembly as it will end up at the end of a long, dark tunnel... But I want it to look busy. Here are the pics: The white styrene rods will hold the fuel manifold in place. In the pic above they are neiter the correct length nor are they in the final position. This are the fuel spray rings (actually they are spares I didn't need in the end). The fuel manifold consists of 8 spray rings, two of each diameter that are arranged in a tandem configuration. They are made from 0.5 mm styrene rod wound around a rod or tube of the proper diameter and then dipped into boiling water for a minute or two. The fuel manifold with the little jig I made for the assembly. The whole thing is quite fiddly... And the manifold in place behind the last turbine stage. I must say I'm quite happy with this. Next up are the flame holders. They are pretty complex and I have no idea how to do them. Some experiments will be necessary, I guess. Lastly, a pic of the compressor face and the ejection seat to show you how big the RM-8B was. One of the biggest fighter engines ever. That's it for today. Thanks for looking.

Derek B Posted November 14, 2016 Share Posted November 14, 2016 That is awesome Rainer (scratch building to the very highest standards - well done). Your work on the engine compressor face and turbine disc and after burner fuel nozzles are exquisite. Derek Rainer Hoffmann 1 Link to comment Share on other sites More sharing options...

Rainer Hoffmann Posted November 15, 2016 Author Share Posted November 15, 2016 Thanks for your kind words and continued support, gents. It's always very much appreciated. Rainer ... I'm speechless! What a phenomenal scratch building effort. What glue do you use?Jim Jim, I mostly use acetone, applied with a 00 or 01 brush. If you are not happy with acetone you can use Tamiya Extra Thin. I also often use Faller Super Expert because it comes with a thin steel tube that allows the precise application of small droplets of glue.
