Look, a workbench!

It’s a little scary watching how time continues to fly by, during which I still have yet to actually start work on this project.  I seem to be getting the workspace together, but very gradually…I’ll make a small step, then something will come up and pull me away for a couple days.  The construction of this workbench is a good case in point.

I’ve been looking on and off at workbench info for a while now.  That’s just my nature…I can be quite a serial planner.  But I finally settled on a slight modification of the classic EAA 1000 workbench.  The design is pretty well-known and in use on homebuilder shops across the country.  I did, however, make a few changes.  First of all, since I’m definitely above average in the height department, I decide to make the tables a little taller as well.  Some of the guys at VAF had done the same thing, so it seemed like a sound decision.  Second, I felt a neurotic urge to make the most of the 4×8 sheets of ply I’d be buying, so I decided to make two 2’x6′ benches and use the remaining ply (2’x4′) to make a third, smaller bench.  Finally, I decided to use MDF instead of ply for the table top and shelf surfaces.

After making all those decisions, I spent a fair amount of time working out a materials list for my shopping trip to Lowe’s.  That trip took about three tries…you see, I don’t own a pickup truck.  Josie has an SUV with a roof rack, but I didn’t think I could transport the 4×8 sheets up there without damaging them, so I decided to use one of the rental trucks at Lowe’s.  Apparently those are quite popular.  It actually took three tries before I secured that thing and got my materials home.  That was last Monday.

Tuesday and Wednesday nights were booked up, so Thursday after work I started sawing in earnest.  I succeeded in getting all the MDF cut and in making the framework for the first tabletop, but then I discovered I didn’t have the screws I needed to secure the top. I was getting hungry by this time, and we needed to run out for a few things.  By the time we got home, it was after ten.  Oh, and the one thing I didn’t return with was the screws.  I thought about working on legs, but figured the neighbors wouldn’t appreciate me sawing wood in the driveway at that hour.

Friday night was out.  Saturday was also booked basically all day.  Finally, Sunday arrived, but I was so tired out from Saturday’s activities that I slept in.  Finally, I made the trip to Lowe’s and returned with the hardware I needed.  Sometime about 6 PM, I finally had ONE completed 2×6 table.  At that point I knocked off and mowed the lawn, which was badly needed.  The remaining two tables are still unbuilt…but that might be a good thing, because the garage will need another organizational bout before I really have room for them.  At least the next two should got together a little faster…

I did get in the Van’s practice kit this past week.  Originally I had hoped to do that this Sunday, but as you can see, things got way behind.  Next Saturday we’re going rating in TN, so maybe Sunday will be practice kit day.  Assuming, that is, I can pick up my compressor this week.  And some other required tools…this is already starting to feel like a cat-herding operation.  I can only hope that things will settle down once I get the shop in shape.

Oh, here’s a crappy cell phone photo of the battleship of a workbench I created.  I’m fairly certain that in the case of nuclear holocaust, cockroaches will be using this thing to rebuild society.

Workshop Prep, Part I

At the risk of stating the completely obvious, before beginning a project like this RV build, one first needs to have a good workspace.  To this end, I recently moved myself to a house with a nice two-car garage.  However, as tends to happen with moves, the garage became a sort of warehouse for boxes of stuff that I didn’t really have a home for.  Since I had Presidents Day off, I resolved to spend the day out in the garage doing some organizing.

The end result isn’t really ready for building, but I did get a lot of things stored out of the way, and generally cleared out some floor space.  There are still some items I have out in the open that are either going to be sold or donated.  I figure that once I pick up a tool cabinet, air compressor, and materials for building my workbenches, I’ll finalize the layout of everything and do another bout of reorganizing.

As it turned out, doing all that cleanup work kind of got me motivated to continue prep work.  Another thing that really needed addressing was lighting.  The garage was lit by two single incandescent bulbs, one of which was burned out.  Completely unacceptable.  So Josie and I went out for dinner and a Home Depot run, and came back with 8 48″ flourescent shop light fixtures, which I proceeded to hang, finishing up just before midnight.  Long day overall, but the change was well worth it.

Learning to Build with EAA SportAir

OK, so I don’t really have any building to do right now.  In fact, I’m 400-some miles from home, writing this in my parents’ living room on my Christmas mini-vacation.  But this blog is in dire need of content, so I’m going to write a few posts about things I’ve done as I prepared to embark upon this RV project.
Anyhoo, one thing that I fidgeted about (probably like every other new builder out there) was the skill set I was going to need to build my plane.  I consider myself to be a pretty handy guy, but all this sheetmetal and rivet stuff was definitely outside my realm of experience.  Being a serial researcher, I did a lot of Googling, read lots of information, and watched innumerable videos on the subject of riveting.  I felt like I had at least a decent handle on the mechanics of the process…but of course, there’s generally a world of different between having the book knowledge and actually performing a task.
As such, I was thrilled when I got an email informing me that there were going to be EAA SportAir workshops in the Atlanta area.  It didn’t take much thinking on my part before I signed up for the Sheet Metal Basics class.  Basically, over the course of the class, I would construct a small wing section, and learn about riveting and various other tasks along the way.
So one cold November weekend, I got up way earlier than usual and drove myself to the Aviation Institute of Maintenance.  A couple cups of coffee raised my spirits while everyone got the general introduction and we broke into our individual groups.  The first part of Saturday was spent in the classroom, where our instructor covered such topics as tools, materials selection, fastener types, edge distances, and lots of other information. (I don’t have the booklet handy, so I’m going my memory here)
Then it was into the workshop, where we got our build partners and started on our first practice project.  This was a fairly simple thing, just a couple of bar stock pieces and an aluminum angle section that had to be marked, clamped, drilled, and riveted together.  Here, I learned an important lesson: The rivet squeezer beats the rivet gun any day.  The first rivets I squeezed were lovely; it turns out squeezing is pretty idiot-proof.  My first attempt at bucking, however…different matter.  Coincidentally, I also got my first experience drilling out rivets as well. (Along with my first time destroying a hole while trying to drill out a rivet. Oops.)
Well, that was educational.  On to the real practice project, the wing section.  For this project, we had to form a couple of ribs, rivet together the wing skeleton, then clamp/mark/drill/rivet the skins.  My partner and I succeeded in finishing the skeleton and getting the top skin marked before it was time to quit for the day.  The next morning, we went back to work with vigor, drilling the top skin, only to discover…crap.  Bad edge distance on one of the ribs, and I was sure I left plenty of room.  Well, that’s why it’s a practice project…we compensated by drilling an additional rivet hole with proper edge distance.  And you better believe I was way more careful with the bottom skin.
The finished product, all things considered, wasn’t too ugly.  Well, except for the control surface section, where it turned out our skin was bent incorrectly, and thus didn’t line up quite right.

The fruit of our labor


I can say without reservation that this class was worth every penny.  I probably could have figured a lot of this out at home with the practice kits from Van’s, but I would have lost out on having an experienced eye to help out and offer useful tidbits.  I came home Sunday evening really feeling like I could build an actual airplane.  We’ll see how long that feeling lasts when I get real kits to work on…
I also gained a real appreciation for the prepunched kits that I’ll get to work with.  All that clamping, marking, and drilling provides a lot of opportunity for foul-ups; I’m glad that the vast majority of that work will be done by CNC machines at Van’s and not in my garage!
(Oh, and I got to take the wing section home.  At some point, I’m going to paint it and put it on my desk at work.  Should make for an interesting conversation piece.)
