Hi

I’m new to the list, and have just ordered the plans for the Falco.

I thought I had read everything on the internet about the Falco so it was with joy when I stumbled over this list.

In my mind I have built many of the parts, trying to figure out how to make them.
First question (of properly many), is how to produce the fuselage frames?

On Ryan’s web page he builds them in halves and then scarfs them together, this looks to me very difficult to do accurately! (By the way a very inspiring builder’s log, thanks Ryan).

On the Sequoia homepage I have seen 2 methods one laminated up in a spiral with every strip scarf together, and the other laminated with the ends of the strips ending where the cuts for the fuselage stringers is going to be.

The spiral method looks the easiest to me, although it probably will take quite some time as each strip will have to dry up before a new one can be glued in.

Any comments to either method would be appreciated, so I can go on figuring out the best way to get started on the jigs.
Best regards
Frank
There is a lot of talk about to little traffic / postings, maybe those having a webpage could link to the list? (I would have found it one of the many times I have visited Georges homepage (Great too) if there was a link there!!!)

Frank,

Welcome to the list. As far as the fuselage frames are concerned, I cannot help you with the other methods but I can describe a little bit about what I did. For every builder, the best method to build something changes depending upon many variables. I chose the scarfing method because it sounded like the easiest for me and I could envision all the steps. I spoke with Larry Black along the way for help and suggestions. I'll try to explain this with links to my website.

First, I laminated the two halves of a given frame, frame 9 for example. Make sure the halves have extra length for the scarf cut and then some.

September 30, 2005

Then I made the scarfing jig shown here with my method for lining it up accurately with the table saw. Make the cut right for a couple test pieces first to make sure you have it down. You have to be careful with which side you take wood off to match the other half of the frame. I used a 10 to 1 scarf, 12 to 1 would be better.

October 2, 2005

The jig I used for joining the halves is shown here. I used the backboard and the mold the keep the frame halves flat and in the correct shape while joining them.

October 13, 2005

I did screw up making the scarf cut once and I had to redo two of the frame halves I previously laminated. Dissappointing, but an easy fix with the mold already made. Attention to detail is always important, but that's true for any method you use. If you have any more questions about the way I did it, ask away.

Above all, use the method that you are the most comfortable with.

-Ryan
