Today, I continued with working on the F-705 bulkhead.  I believe that I mentioned in my previous log entry, that I spent a lot of time looking for where all the pieces and parts to the F-705.  Slowly, but surely, I found all the pieces and parts, but I had a heck of a time figuring out where I put the material called out to make the F-705H spacer.  Sure enough, I found it in a little divider bin marked "misc fuselage parts".

Fabricating this was pretty straight forward, but it was small enough that it made it hard to hold. All I needed to do is run a finger through the band saw.... Tami and I have made our max out of pocket expenses on medical, but I really didn't want to go to the doc.....

I cut the remaining pieces left to fabricate.  The F-705K's need a 4 degree bend....  How am I going to get a nice looking 4 degree bend without a brake?  I have access to a nice brake at work.  I may just haul them in with me.

Once you fabricate the F-605C (bar doubler), the F-705B (center section bar), and the F-705H (spacers), you have to match drill them to the pre-punched F-705A (rear spar attach bulkhead).  Anyway, that is a lot of material to drill through.  Back in my empennage days, I remember trying to drill through a large amount of material and not getting the drill bit straight.  That resulted in oblong holes and nothing sat straight.  In an attempt to not have that problem again, I decided that after I clamped all those pieces together, I would level everything out and drill the holes with the drill press.  This actually took some time, but worked great.

Here I am getting ready to drill the hole through the spacer.

What I ended up doing here for the hole going through the spacer was to first drill through ONLY the F-705A and the F-705B.  This allowed me to center the spacer in the hole.  I marked the center line of the spacer and then centered the line in the previously started hole.  When I was satisfied with alignment, I clamped everything together so the spacer wouldn't move and drilled through the F-705H and the F-605C.  Worked great.  I ran a AN3 bolt through it all to make sure that my hole was straight.  Looked good. 

Here you can see how thick all the pieces are parts are.  A slight angle on the drill bit through this much material would make a crappy hole.

Not as much got done today.  I spent the rest of my evening cleaning up the garage.  All this fabrication makes a lot of aluminum shavings.  I found  some upstairs in the bedroom the other day.  Time to clean up so I don't drag to much of that junk in.  Tami is understanding, but.....
