F704-H Question

macrafic · #1 04-06-2008, 06:11 PM

I've match drilled the F704H to F704C and D. Those would be the rivet holes on the outside edges of the 704H. On the inside, however, on the fork, there are also rivet holes. What do these get drilled to? What do I match drill them to? There is nothing underneath them. Have I missed a part somewhere along the way?

Thanks!

Rich,

I spent hours researching this over the last few days. Fortunately, I have a couple of QBs on the field not far away. Looked at one and the only thing the inner holes near the cutout are for, is to attach the outer side skin to the F704H. I think the rivet callout is 470 4-5 and they look long to me for that, but that is what I concluded. I think the bottom hole has a pulled rivet in it. Should be able to squeeze the rest from the area where the spar will go in. If I am wrong, will someone that has already done this please correct me.

Sir, you are correct!

The .032 skin and the .063 side plate call for a -5 rivet. I pre-riveted those with the skin off of the fuse; just some fancy angling technique with the squeezer should do.

I'll have to stop by and check out your progress soon.

Thanks for both of us. I wasn't real sure, but had spent hours, really, looking through all the drawings to see what goes behind there. Thought I had forgotten something. Made my wife more comfortable last night when I saw this post as well. Hope to prime center fuselage tomorrow if weather permits. Stop by any time. BTW, how is yours coming. Need to bring my wife by to see it. I am in Norfolk, VA today. Should be home this evening.
