Training project

Post by dirtmanf800 »

Ok, I know this is a non working part and I may be putting to much into this but here goes. The stiffeners show nine rivets in them, with the first one .75" from the trailing edge of the stiffener and 1.25" spacing for the rest. After the eighth rivet there is only 1.125" of rib left. Should the last rivet be placed using the minimum edge distance from the end of the stiffener? If so wouldn't it be better to change the spacing for the rest of the rivets to equally space them? :?

I spaced it so that both met the .75" spec and the rest were equidistant. A rivet fan make very easy work of this.

dirtman,

First of all, great username! I did exactly what you described. Even though it doesn't fit right, I just used the spacing they say to use, then used edge distance for the ninth rivet.

I am in the same boat as you, but going to build a -7. I finished the third wall of my shop today, and will finish the last wall next weekend to complete the remodel of our garage to my shop. I am going to build a huge work table as well (4x8), and I am going to order the tail kit at the end of the week. Collecting tools is just about complete, and preview plans are being studied.

Back to the subject at hand, I detailed my training kit on my website (see below). Spike did the same thing, so check his too! Actually, I am planning on ordering another training kit with the emp kit, just to brush up before I dive in.

:)

I have not needed it yet and I am just about done with the tail. However, I am glad that I have it as you never know when you might have to lay out a line 'o rivets :)

For the standard kit, it is not necessary.

For my OLD kit (70312) it WAS necessary. The Elevator stiffeners were NOT pre-punched!

Wicked Stick borrowed mine to lay out a row on the rear of his fuse that wasn't on the plan. That was the first occasion HE needed it.

I suppose when it comes to interior stuff and finish kit stuff, it could come in handy again.

A bit late on the reply, but I got into an email dialogue with a guy at Van's about this, and I was pretty disappointed in his attitude, which was,
"it doesn't matter, because it's a practice kit." Excuse me? Isn't part of the practice, to read and interpret drawings and written instructions and look for discrepancies exactly like this?

I put in 9 rivets, putting the first one 3/4" from the trailing edge as noted, and using a spacing of 1 3/16" (1.187) and it ended up looking like the drawing, except that it's nine instead of eight rivets. I told the guy they ought to fix the instructions; he said they'd look into it, but I could tell he was just BSing.
