Bandsaw

Tuesday, March 7th, 2006

I broke down and bought a bandsaw:

I think this is the same $99 Delta unit that everybody else buys for their RV. I put a 15 TPI blade in it, and it cuts through aluminum like butta. I spent most of my limited evening fiddling around with the 972 little set screw adjustments on it, then used it to cut out these funky looking gussets:

I've got enough finished parts built up now that I can probably do a medium sized batch of fuselage riveting, once I do a medium sized batch of deburring, that is.

Finished baggage floors

Sunday, March 5th, 2006

I finished fitting and attaching the nutplates that will hold down the baggage floors. I ended up putting a screw and nutplate in each and every one of the prepunched rivet holes. This is probably a ridiculous amount of overkill, especially along the F-706 bulkhead, but it's certainly strong enough.

After vacuuming out about a pound of aluminum shavings from all the drilling and deburring and whatnot, I put in about a third of the screws just to hold things in place. You can also see where I fitted and attached the baggage tunnel cover. The baggage floors are now completely removable but still entirely flush-mounted, which makes them look classy.

I liked the countersunk thing so much I actually drilled out most of the factory-installed K1000 straight nutplates that are used to attach the forward seat pans, and replaced them with K1100 countersunk nutplates too. I figured, why not go all out so everything matches? Also, I was remembering how the panhead screws in my last RV used to tear little holes in the seat upholstery.

I am officially sick and tired of installing nutplates, as well as actually being sick and tired. Now, to rest so Mary can stop worrying. Can you believe she doesn't think it's a good idea to stand up in the garage all weekend when you have a cold? She has these crazy notions about "getting lots of rest" and "drinking plenty of fluids".

Hard landing

Saturday, March 4th, 2006

Oops, had a little accident in the shop today. Mary came home from the store and pressed the wrong button on the garage door remote, causing the door on the side of the garage where the fuselage is to try and open. Since the tailwheel was sort of resting against it, the door picked up the tail of the airplane a few inches and then dropped it back onto the wheel. Not her fault, I should have unplugged that garage door opener (which I subsequently did). Anyway, the only damage was the shearing of the two little keeper rivets – no big deal, they were easy to drill out and replace – and some scratched paint on the weldment.

After repairing the "damage" and then thinking about it some more, I decided to remove the tailwheel and let the aft end of the fuselage rest on some 2" styrofoam insulation instead. Although I got the go-ahead from Van's before I put weight on the tailwheel in the first place, it's obvious now that it was never meant to hold up the airplane with only two of the five the bolts in place. The fuselage can go back on all three wheels once I get the vertical stabilizer fitted, but for now it will sit on the foam.
