April 2, 2001 Update
Well, this is what the thing looks like balancing on a set of bathroom scales (you _can_ see the bathroom scales under there, can't you?). It weighs 85 lbs. as yo see it there. Belly panel is underway; interior fill/sand/prime nearly complete.

This is what the rough, unfinished joint between the cabin and empennage looks like after laying up a 4" and then an 8" wide strip of glass over the seam, both inside and out. I carried the reinforcement all the way up to the roof; plans only require it up to the level of the top longeron. The belly has yet to be added, so the bottom edge of the cabin was left unprimed and ready to wrap the belly glass overlap onto it. Also very noticeable in this photo are the differences in the lines of my windows as compared to the prototype's.
Here's the inside of the rough, unfinished (but primed) seam. I typically rough-sand with 60 grit or so, then prime, then rough-sand again with 60 grit, to show up the low spots. The next rounds of sanding are with 120 grit. Visible in this photo are the (unfinished) edges of the insets I'm using for my windows. The prototype's windows are screwed directly to the outside of the frames, but I've provided rabbets to make the windows nearly flush with the outside skin.
Now compare this with the first shot. This side has been filled, sanded, and primed. It's now smoother than the raw, unfinished joint, but you can sure see lots of lumpy places, dips, pinholes, and open cloth weave. It will take about another 3 rounds of filling, sanding, and priming to get it ready for smooth prime or paint. Also noticeable in this shot are my cutouts for the aileron bellcranks. I made the cutouts a bit more to the size and shape actually needed for clearance, rather than just making large half-moons as called for in the plans. I intend to find some sort of rubber boots to cover the holes, too (maybe something like parking brake lever boots from a VW or something). I'd like to keep air, rain, and noise out of the cabin.
Another view of that "kinda finished" seam. I don't like the way the contours of my fuselage turned out. I wanted them to be rounder, but they ended up somewhat angular. Oh, well; I'll get it right on the next one I build ;o)

Aft section of the cabin roof finished, sanded, primed. Rear window framing in place. I've framed my rear window differently from the prototype, and am thinking of installing a hinge across the leading edge of it to allow opening it for access to the baggage area. I've also smoothed, glassed, and primed the joint in the cabin floor where the cabin and empennage were joined (two layers of glass). Still working my way up the sides.
Side view of how I've framed the rear windows. Foam has been built up and sanded, but not filled or smoothed yet. And of course I haven't yet glassed over the cabin/empennage seam here.

Yes, here is the M-19, cabin joined to empennage, stuffed into my workspace (my half of the garage). My wife called it "the kayak bumping into the back of the choo choo train". The rear window framing is cut and fitted, but not yet glued in place in these photos. I have changed the lines of my rear window "greenhouse" from that of Marvin's prototype, as you will notice in this and following photos.
Here is the view looking in through the rear window, showing how I'm framing the greenhouse. Across the top is where an aft section of the cabin roof goes; it's not called out in the manual, but is obvious in photos of Marvin's plane. I've added a framing crossmember there, to mount the leading edge of the rear window onto. I've also changed the lines of the two main runners, where they now tie into my bulkhead rather than down onto the longerons. When I add the foam and glass, it will become more obvious what I've done and why. From this photo, however, you may note that my rear window will be flat, while Marvin's has a flat top and sloped (bent) sides. You can also see the strings I've used for leveling and truing the empennage for joining to the cabin. A vertical string (very thin; barely visible) in the center of the rear opening of the cabin has a pyramid fishing sinker as a plumb-bob, right where the floor of the cabin joins the floor of the empennage. The two strings centered up perfectly before I joined the halves.
A view looking in the door. In this shot, one of the rudder cable fairlead blocks is visible just forward of the cabin/empennage joint at the floor.
A view looking in through the windshield. The centering strings and my fishing sinker "plumb-bob" are visible, as is the rudder cable and elevator cable fairlead block. Rear window framing lines are apparent.
View down the tailcone. What is most evident here (to me) is that the top line of my top cowl, or the top edge of where the instrument panel will be, isn't perfectly level. I knew that the minute I finished glassing it, but didn't want to tear it out and fix it. I had to make the instrument panel slightly skewed on top to match this, but I've figured out a way to hide it. Wait till it's done to find out how ;o)
Yes, this is a milestone in the construction, a bit more than 2 years after I first cut wood on the project.

If you're not building yet,.........................why not?
