LFG Roland C.II progress

VNulk · 22 July 2008, 12:59 PM

Building has been very slow for lack of focus and time. I have a few photos to post but did not document all that I could have. I'm rushing now to get it airborne in August. The major project now is the muffler fabrication. A stock muffler for a G-62 is just wrong for a C.II! I should have pictures of the engine installation in about a week.

I have more to assemble before I take any "beauty" shots but a friend took these in Feb.

Vern, nice job, is she from a published plan or from your own drawings?

Hi Steve, ZZ,

Thank you both for the comments -much appreciated. The model is based on a set of drawings I started 15 years ago and got published in WWIA. Since then, they have seen many edits to correct details I messed up on or missed. I'll get the latest versions, or links for them posted this weekend.

ZZ - Thanks good to see that you're still around. If I can get the beast in the air, I'll see if I can get a clip posted. Tell us what you've been up to or send me an email.

I'll be around,

Vern

The included .pdf's are the latest versions to date. I'm afraid that there are a lot of construction details that I've yet had time to include on them but they getting better for reference purposes.

The addiional photos demonstrate the method used to fabricate the fuselage louvers from aluminum flashing.

Vern, what instument do you use to press down the flashing along the sides of the male form (producing the edges)?.........John

Hi John,

I'm sorry - I neglected to include any description of the process, which isn't much. After clamping the flashing to the top of the plywood form, The desired shape is slowly formed on three sides by laying, in my case, a 1/4 " dia rod (brass in the photo) on the flashing and tapping, with increasing force as you work around the shape, and force the side of the rod into the crevis where the shape meets the base material. Gradually working the rod around the corners shapes the flashing and gradually removes noticeable impact lines. Minor straightening after removal and final cutting and drilling is all that remains.

Does this help, John?

Vern, I'll give your method a try on my upcoming D VII, an OAW version (with the funny little louvres all over) since they are commercially unavailable and difficult to reproduce in wood ala BUSA. Very clear explaination indeed, Thanks.............John.

John, here's another shot of the louvers in place - I glue to the fuse with the head of a heavy straightpin for fasteners after cutting an appropriate slot through the fuse. They're very easy to make and with a little care, look really sharp. Your DVII would be an excellent candidate.

Other shots include the wing-mounted compass, the rudder cable fairlead, and the spring catches holding the nose cowling sheet metal together, purely for detail and not functional but be my guest if you want to try!
