Posted: Thu Apr 09, 2009 3:40 pm Post subject: Diagonal tube placement /fuselage cabin frame. |
|
|
When I place my diagonal tube against the rear wing bracket there is a slight bow where it goes into the steel cabin frame tube at the forward wing attach point. In order to straighten it out I have to bring it about a half an inch or so away from the rear wing attach bracket.I set the distance to 710mm as I have not built the wings yet. Everything is square measuring diagonally at the top of the cabin frame. I would like to keep the tube against the rear wing attach bracket to get as much to rivet to and attach my bottom gusset to also. Any thoughts? Thanks.

Harvey, I would wait to rivet the diagnal brace in place until you set the cabin frame spacing to fit your wings. As a matter, that is exactly what I did. You might find once you set the spar spacing to your wings, that things will line up better.

I set the spacing to 710 mm Doug and then was going to build a template from that for the wings. I see in George Races pics that the tube does not appear straight also. There is a slight bow at the front where it attaches to the 4130 cabin frame,almost like the angle is slightly off where the tubing is welded. When you sight along yours Doug is it straight? Thanks

Mine is straight Harvey but remember, I am scratch building. I put the front diagnal fitting up in place unwelded and tacked with a mig. I then took it all apart and oxy/acet welded it. This way it lined up correctly.

Thanks to you both for the reply. I was trying to get it straight but that is not possible. Do not archive.
