HI THERE,  

JUST A BIT OF BACKGROUND FIRST, I AM KIT BUILDING A 601XL, STARTED IN 2002 AND AM PRESENTLY DEALING WITH THE CANOPY.  PLANS SAY TO RIVET THE FLASHING ON THE INSIDE, BUT WITH THE CABLES INSIDE OF THESE,  WOULDN'T IT BE BETTER TO USE SCREWS?   I HAVE ALREADY DRILLED MINE FOR AN4 RIVETS SO WHAT SIZE SCREWS TO USE?



THANKS

Just add access hatches over the cable end adjustment devices. That should suffice.

just rivet it.  it is quicker to tap rivets out than unscrew the thirty or so holes.  you will hradly access it.

Hi Glenn,

Good question, and if I were using screws, I'd use AN526 machine screws 

6-32 thread.  A screw like that used on the canopy tubes is probably not 

a good idea as

they have the material thickness and washers etc supporting them. I'd 

personally be inclined to keep the AN4 rivets and forget the screws.

The rivets you'd normally use will hold bows and frames better and the 

cables you install will likely never need adjustment, but drilling out a 

couple dozen rivets is probably no more effort than trying to tap and 

align and install screws.  The bows rely on the security of these rivets 

in flight and I wouldn't be comfortable with screws for that.

The ball peen hammer process can be done neatly, but you have to place  

the unseen side of the flashing up and the exposed side

against a smooth  block of steel.  Cold rolled steel is usually very 

smooth. 

  

 +++ Larry is correct, just takes practice.  If you can beg/borrow/buy  a small hand planishing hammer (check Brown or Avery) to replace the ball-peen  hammer, you will find many uses for it where you want to massage a piece into a  mild curvature.

  

 +++ If you have a table saw the cast iron top is ideal for this work as it  is smooth, of good size, and usually at a comfortable working level.  Much  of the sheet metal shaping on my a/c was done with a large spoon (about 60 mm by  90 mm) liberated from the kitchen and the top of the old Craftsman table  saw.  After four years the wife finally noticed it was missing.

  

 +++ As always, practice, start slowly.

He does good work. If I did it that way I'd probably have to drive my flying car to the airport for my 601's first flight.

a thought on that.  I am building in a complex that has 4 other builders building 601s. We get people passing by all the time looking to jmp into a zenith project.  Some building, do the "just Git' er dun", some stick to the principal "its done when its done".  Its amazing to see the outcomes on each.  When people ask me how long it takes, I have found the best answer in kit building is "the published times acording to the adds is 400 hours.  However at the 99% complete stage, you could easily add another 400 hours.  Its the final 1% effort that makes all the difference."

I guess that is the case with any work in life.

Hi Juan,

		   I appreciate the compliments but you give me too much credit.  A scratch builder has the prerogative to ditch the bad pieces over and over again until the job is done right.  I think for every three pieces that went into the 601 there were at least 1 or 2 that ended up as scrap.  The wife would say we have $50K in the bird and I can only account for $35K plus a lot of work.  Anyway, the best project I ever have been involved in was this design by CH.  You have to give him the credit for providing a super product that really motivates so many builders.

i second that. some days I could have tossed the entire project in the trash I was so pissed at a botched part, other days I thought I was the man with the plan with every thing going great,  its been fun.
