Pre- fabricated Spar

Postby Andy » Sat Nov 06, 2004 12:54 pm

Hi,

I know this a new site but thought I would give it a try.
I've just ordered my wing kit but didn't take the Pre-fabricated spar.
Has anyone built one from components?
Or is the consensus to go the Pre-fabricated route?
I'm trying to get it added to my kit but fear I may be too late :?

Building the spar ....

Postby Spike » Sat Nov 06, 2004 1:00 pm

I have a friend that is building an RV-6A and does not have the prefabricated spar. I helped him a bit with his and got talking to him about it. It seems that building the spar isnt that diffucult, its just a bit time consuming. That seems to be the big attraction to getting the spar pre-assembled. People are saving more time than heartache. Driving those big rivets takes a while :)

Van says the pre-fab saves approximately 40 hours.

RV4 wing spar

I wish that I had riveted it myself. When I built my RV4 I ordered the spar built. Big rivets need a big hammer. Just use a jig to hold the sets and use litteraly a big hammer. If you do it yourself you will learn a new skill! That is fun!

You should be able to send all the parts to Phlogiston or whoever does the preassembled spars for Van's. That would probably cost more than ordering it from Van's. I'd say if you can, get them to change it but if not don't sweat it. You'll do fine.

spar

Postby arffguy » Tue Nov 16, 2004 9:44 pm

I didn't want to have to prepare (polish and clean-the worst part to me) for priming all those pieces and then worry about driving the fat rivets. It was an easy decision for me. However the guys who built their own have a skill that I don't, I guess. Do you have more time or more money or do you want the pride of doing it yourself?

Spar building

Postby poeboy » Tue Jan 18, 2005 10:35 am

Andy - I'm the friend Spike helped build his own spar. As everyone else here said, it's not hard and I'd concur with the 40 hour estimate of building time (for each spar). You need an Avery (or other) C-frame tool and a hefty (3-4 lb) hammer to drive the big rivets, but it's not hard. You'll also need a couple of friends to help hold things while riveting.

HTH,

I think he’s referring to the Phlogiston spar which is pre-made.
