Dear Listers,
I'm getting close to mounting the engine on the 'ol RV-8. I'd like to hold off riveting the front top skin on until I'm sure all of the wiring and what not works with the various engine sensors. Is it "safe" to mount the engine before this skin is in place? Also, I have a QB and I noticed that none of the rivets along the sides where the cowl hinges go are riveted save for a couple of temporary pop rivets. Can the engine be mounted before these two areas are completely riveted?
Thanks!

My engine was on the mount for years before I riveted the front top skin. I'd do it that again. I checked my photos, and the rivets between the side skins and the firewall flanges (the ones that hold the cowl hinges) were also done after the engine had been hung.
Good luck hanging the engine.

On my RV-6 I hung the engine without the top skin but I'd recommend putting
a rivet in every hole on the side skin to upper longeron. There is a lot of
stress on those skins so I would not do it without riveting the side and
bottom cowling attachments.

I would echo the same thing. It is just not a problem to mount the engine without the front upper skin on. There is a great little instruction on the VAF web site on mounting the engine. You definitely need a friend.

Yes Matt, I am looking at the same problem. I am building a slider,
and the front section of that can't be built until the top skin is in
place.
I would like to start the motor to verify all of my wiring is OK.
It's going to be a bit dicey not having those rivets in place and 200
HP thrashing around in the front
I would be interested to hear what others have done

Hum, hadn't though about actually starting the motor without the skin on. I was just thinking about whether it would hold the static weight. I guess to test all the wiring, the engine would really need to be started.
So I guess I'll rephrase my question to "Could the engine be hung AND run without the top skin and sides riveted?" ...?

Hung without top skin: OK
Run without top skin: I wouldn't

The engine thrashes around a bit at start and shutdown, and I'd want the structure to be complete. I wouldn't recommend starting the engine without having all the rivets in.
You should be able to test about 99% of the wiring without starting the engine.

I wouldn't start the engine until you have a complete airframe, wings
and all. That is a lot of torque swinging around up there. You
should be able to test all of your wiring without running the engine.
You can dunk temperature sensors in hot water, pressure up pressure
sensors with air and hit thermocouples with a heat gun. You can
disconnect the starter wire from the starter and hook it up to a light
to test the starter circuit. The alternator wiring is a little tricky
but it's simple enough that if you have the rest right then you should
have that right too. Besides even if you don't have it right the
chances are that it's all forward of the firewall anyway.

Matt...
I am about the same place on my -8 QB and doing the same assembly sequence. Since the engine mount attaches to the longerons there is little stress induced into the skin at the firewall. The load from the engine mount is distributed to the skin progressivly from the firewall aft.
I would have the cowl attach hinge mounted to the firewall since any thing that you mount to the engine side may complicate adding the hinge later. This will also allow you to take out the temporary "pop" rivets and rivit in the hinge. Actually there are very few items that pass through the fire wall that can't be accessed after skinning the forward area. On our first -8 build we hung the engine and did all wiring after fully completing the fuse. No real problems doing it that way. Plenty of access to everything.
