    --> Europa-List message posted by: "JR (Bob) Gowing" <gowingjr@acr.net.au> To Dan Bish and do not archive because I am mainly expressing my opinion on what the factory says they don't know. By spreading the area I meant making it bigger and progressively weaker to dispell the stress. So don't make up a couple of straps of 3 plies of bid and cut it out on the plastic and apply it. This will stiffen the fuselage in small places with sharp edges which ought to be tapered. Make a paper pattern the size of the smallest piece and draw it on your plasic then make the succeeding layer say 2 inches or more wider and the next layer that much wider again. Thus the stiffening will be progressively weaker and closer to that of the fuselage shell itself. I will be interested to hear more about this as I have yet to get to it.

    Subject: Re: Firewall Cutout before module bonding
    --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@ukonline.co.uk> Hi! Tony. IMHO don't force the cockpit module to fit down precisely. Be sure the "lower fuselage moulding" is adequately supported and suitably braced for the width dimension to fit the cockpit module. Then have a dummy run and mark out where the cockpit module will sit in a relaxed state. Remove it then overturn it and have one person apply a redux bead to all its surfaces that will contact the inside of the fuselage. Another person also applies a thick redux bead to the fuselage ready to receive the cockpit module making sure that there are gaps where the tufnol control bearings will be located (you will have a "bad hair day" if when it has all cured you can't move the controls!) then carefully turn over the module and lower it into place allowing the excess redux beads to squidge out from between the two surfaces. I wouldn't apply any undue pressure anywhere other than to ensure there is contact of the redux between all necessary surfaces. This is best observed by shining a strong light underneath the fuselage which clearly shows where there isn't redux contact. Trowel off all excess redux and use the excess to trowel it into any gaps. This way you won't have any outside filler to apply and fill dimples which the application of screws or pop rivets cause. It's obvious that a little more redux will be used but at least it has structural strength where the addition of filler adds only the weight and can flake off later . You shouldn't get any cockpit module distortion which would be likely to make the controls tight. Also make sure that the aileron control arms clear the fuselage bottom for their full travel range.

    Subject: Re: Firewall Cutout before module bonding
    --> Europa-List message posted by: "Paul McAllister" <paul.mcallister@qia.net> Tony, If I was to do it again I would not use screws, rivets or anything mechanical to pull it together. I would have supported the bottom and lowered in the module and pressed it home with weighted shot bags. I had a big bunch of these that Jenny had stitched up. If you want to make some up quickly you can buy # 4s hot gun pellets and put them in zip loc bags. I would at least experiment with this idea and if you can't get good gap closure then I would go with plan A. For applying the Redux get your self some empty silicone gun tubes. I had tried icing bags, toweling it in and various other methods and I would have to say it works 10 times better than anything else. Good luck, Paul

    --> Europa-List message posted by: EuropaForum <Post2Forum@comcast.net> I have my gusset plate plywood installed, an I'm moments from putting in the tie bar. The update to the manual says to install PLY 12. Is that a part # that I didn't get with my kit or are they saying to install 12 ply plywood? I installed 5/8, 5 ply plywood. ( I found "part # PLY 6" in the new manual ) It's always something : ) Steved.

    --> Europa-List message posted by: "Sidsel & Svein Johnsen" <sidsel.svein@oslo.online.no> Steve, PLY 12 is a piece of good quality plywood, 14 inches long, 1 inch wide, 11/16 inch (17,5 mm) thick. I found mine only after I needed it - I used a piece of marine plywood cut to size and filed to thickness ( = outer diameter of the tie bar). Regards, Svein K.

    Subject: Re: Firewall Cutout before module bonding
    --> Europa-List message posted by: Tony Renshaw <tonyrenshaw@optusnet.com.au> Empty Silicone gun tubes.....................what a great idea!!!! Ok, bit of questing required now, but I should be able to overcome this one. Thanks Paul, yet again a saint, or should I say "wise man". My cockpit module doesn't seem to sit as flat as it might because there is a several ply buildup on the flange that attaches the vertical front face of the thigh support to the floor. The reason for this is that my maingear attach points required some thickening there. If I now weight down the module, I seem to have a see saw effect, and whilst my flight controls sit all on one side of the fulcrum, I don't want to force the issue. I think I will resign myself to a little extra redux, and a diet post build. Firewall cutouts. I dont see any reason why I can't take out the front of the tunnel, as it will allow me to ensure good adhesion between module and firewall, and between module and floor. Any couter arguments on that one??? I reckon I can even install the gear mount whilst the module is being glued down, in pre drilled holes through the firewall, so that the spacing remains exact and things don't tighten or loosen whilst gluing. What I mean by tighten or loosen, is the gap between the 2 holes at the bottom where the bottom of the module could flare out under too much weight etc. Reg Tony Renshaw At 10:33 PM 6/27/2004, you wrote: >--> Europa-List message posted by: "Paul McAllister" <paul.mcallister@qia.net> > >Tony, > >If I was to do it again I would not use screws, rivets or anything >mechanical to pull it together.

Gentlemen, I understand the XCOM intercom may be the answer to your problems with the microair. I will pass on your postings to a person who will be able to give you very reliable advice in this regard. In the meantime, you may like to check out the following link to the XCOM intercom. http://www.mcp.com.au/xcom760/intercom/intercom.html and no, I'm not on any commission.
