Ok I am just now setting my first real dimples in the HS spars and ribs,

  pneumatic squeezer, do I want to see the slight ring imprint also ,? or am I just a little deep ?

  How about when I get to the skin ??

  Thanks all,.,

I overdid the dimpling on my first try.  I used a lot of pressure.  TOO

MUCH.  What you want is to have the dies just touch the surface.  In my

case, the excessive pressure caused the holes to expand, making a cleco not

hold well.



Another test is to insert an AN426 rivet.  The top of the rivet should be

flush with the skin.  And the mating part, the spar or rib, should be

dimpled enough to accept the skin without visible separation.



Hope this helps.



Dan

The slight imprint is good and is not a problem. It

means the die has fully depressed the dimple.  If,

outside that ring,you see bulging, it is too much

pressure.

Yes Dan, I used a pneumatic squeezer extensivly and had the same effect. 

Just set a rivit in the dimple and it will show you if the dept is correct. 

Use some scrap alum. sheet for practice when you go to a different thickness 

to set the dimple depth. I think they say, your not building a swiss watch 

here. Have fun. It will look great.
