|
|
Hi all,
I am about to rivet on my front skin. In reading through various posts on fitting the baggage door, there is discussion of drilling from the inside. To do so, the rudder pedals have to be out. I was thinking to finish up the pedals and bleed the brakes (check for leaks) before riveting that front skin. If I need the pedals out to drill the baggage door, then the brakes will have to wait.
Question is, with a pre-punch fuselage kit, do I still need to drill from underneath or can I assemble the baggage door on the bench and expect it to fit? The rest of the pre-punch has fit perfectly.
Any experience out there?
Regards,
Michael Wynn

In my opinion, wait until the very last minute to bleed the brakes. You never know when you might need to take the rudder pedals out for some reason - case in point. I did the final assembly of the baggage door from the under side and was glad I did. There is a lot of twist in the door without the bottom skin on. For a perfect fit, do it mounted and from the underside.

If you want a baggage door that fits perfect (not just good) do it my way.
Being an overweight oldfart, I didn't want to do it on my head from the
underside. Get all the pieces ready and cleaned up with solvent and
scotchbrite. Use 3M structural Epoxy, JB Weld, or any good structural epoxy
and assemble with clecos and then strap down flush. After the epoxy sets it
will be perfect forever and the rivets will just be to fill the holes. I'd
put the fit of my baggage door up against any RV8 out there. Also use a Gas
Spring with geometry such that the spring will hold it closed if you forget
to lock the latch but once the door is raised an inch or two it slowly
raises it to full extension and the holds it up. The only way to fly!
Thanks!

As far as the selection of a strut to hold the door open/closed, I found a sweet unit at McMaster-Carr that fits and works perfectly. Here are the details from my log entry:

Michael, yes you have to drill and rivet the bag door while its mounted if you want it to fit right and tight. Also you have to get inside and under to pull rivet the door back skin on which holds the door shape. I put the pedals in and out a bunch of times before finish. Fill and bleed the brakes so you know all the tubes and parts work and don't leak then disconnect to the last thing, but you'll have to get inside probably more than once.

Great advice from all of you. Thanks!
I guess I will check the brake system before I rivet on the front and then drain it and refill when its time for final assembly. Sounds like I am going to need to get in there more than once before all is said and done.
