Tail Cone Deburring Part #6

More deburring.  Almost all parts get the hole deburring, edge deburring with the ro-lock ripoff, 1" scotchbrite wheel in a die grinder, large scotchbrite wheel on a bench grinder, emory cloth, scotchbrite pads, various files, etc., etc., etc.....

Yes! That is a huge pile of parts!  Glad that is over!  For the wings, I may deburr as I go so as to not have such a huge pile to do all at once.

And even more deburring!

Here is the pile so far!  Man that is a ton of work!  One more day to go I think... Then primer!

Just more deburring!

Tail Cone Deburring Part #3

 Tonight I gathered up all the J Stiffeners and went to work deburring them.

 First I used the EZ-Burr tool to deburr all the holes.

 Then I used the large Scotchbrite wheel to round the corners and to deburr the edges of the stiffeners.

 Next I deburred all of the backsides of the longeron holes for the skins.  No need to deburr the other side because they get countersunk.  I also deburred all the other holes in the longerons like the ones for the aft deck and the seatbelt attach point.

 Next I marked the longerons for the holes that do not get countersunk.  This is a bit of a brain teaser so pay close attention to the drawing and count the holes!  The aft most set of rivets shown on the plans go into the aft most bulkhead not the longerons so take that into consideration when counting!

Next I used the countersink tool to countersink all of the longeron to skin rivet holes with the exception of those marked above.  That was a bunch of countersinking!  My floor is full of chips!

Tail Cone Deburring #2

 Got started tonight by deburring all the holes in the other skin.

 Then I used the ro-lock ripoff to deburr the edges of the skin.

 Cut off the forward triangle on the right skin.

Deburred the rudder cable exit hole with some diamond files.

Tail Cone deburring

 Started deburring the millions of holes and edges of the skins.  Bottom skin first.  I am using this new to me in and out double sided blind deburring tool by EZ-Burr.

You litterally just spin it up, and insert it at a nice steady pace and then retract it at a nice steady pace.  Works like a dream.

Short little demo video to show how fast it is.  Remember it is deburring both sides of the hole at the same time!

 Then I went on to deburr the edges of the bottom skin.  I used the die grinder with a 1" scotchbrite wheel inserted.

I then deburred the top skins.  Switched to the ro-lock style pads in a 90° die grinder for these.
