Hello, I just finished the rudder and thanks to all contributers to this

list because my trailing edge came out real nice. 



I added a picture series of the rudder construction on my site

www.wellenzohn.net



Here are two questions:

1) How can I remove ProSeal spots from the skin (an easy way pls)



2) The HS construction requires 3/32 match drilling (HS Spar & Spar caps)

these drills didn't come with the Tool Kit I bought and I can't find them

on the tools webstores. Since I reside in Switzerland I wonder if match

drilling with a #40 would also do it. Any suggestions?

I have found that you have to let proseal just wear off....when it's still uncured you can use MEK but it is harsh on the skin.



You should be fine using the #40 drill bit or it may be easier to find a 2.35 mm bit in Europe. Either should work fine. The difference in size between a #40 and a 3/32 would be measurable if you were doing precise drilling on a lathe, mill or drill press but using a hand drill in soft aluminum, the error (wobble) factor is greater than the size difference.

 Proseal can be cleaned off with MEK relatively easily.  I don't remember the need for a 3/32 drill bit but that would be an "A" size bit.  Probably easier to find it as that than 3/32.

I have found that Coleman Lantern fuel will clean the proseal spots off,

and it evaps very quickly, with no residue. But use it in a well

ventilated area, it will cause a bad headache! Also it is not as harsh

on your hands or lungs as MEK, and cleans as well. This is what I used

on the tanks of the 7, and it is readily available at discount stores

and outdoor stores.

I used a #40 and it was fine.

Thanks guys for your input! I'll continue drilling with a #40 once my compressor works again, need to fix it (what a waste of time). Will go flying through the swiss alps this weekend (beautiful weather here) pictures will be added soon after on http://www.wellenzohn.net

     I found the air drill a pain to use. First  there is the cord that seems to hook up on something and then there is that  noisy compressor that keeps kicking in. I just purchased a Black and Decker,  "firestorm" 14v cordless drill kit. It comes with 2 batteries, and a charger  that will charge them both at once if needed.  It also has a drill chuck  that pops off and makes it an easy bit driver (important in FLA, since i just  installed 93 hurricane panels with a bit driver).  Since i switched to this  life is easier... i was using a corded  drill, still easier then the  compressor.

Are you serious?  You are toting around a heavy cordless drill, worrying about keeping batteries charged, and turning slowly while building an airplane that has about 50,000 holes to drill?  I really hope I am missing something here.  Yeah, the air hose can be a pain, but it is a lot easier than toting around a backpack compressor.  You would have to pry my air drill out of my…well, you know how that goes.  

   

Anyway, I hope you really aren’t building an airplane with a cordless drill.

most cordless drills will not give the speed needed  for drilling alloy! Refer to Vans notes on this.

Geez, I wish I'd have known that my B  & D 14V "Firestorm" wouldn't work well.  Just finishing the fuselage  with it now.  Personally I think high speed air drills are your enemy not  your friend.  Much easier to drill out the occasional bad rivet with a slow  turning cordless drill!  My $.02

Yikes..  Flame war over drills?



As a famous engineer once said... "Use the right tool for the right job!"



Air drills work well for drilling aluminium, cordless/hand drills work 

well for drilling out rivets, cordless screw drivers work well for 

deburring..



As always, your mileage may vary.
