Bud,
I have the intercoolers done. Take a look at my web sight under page Europa.
I took the pictures with a higher quality camera. Tell me what you think. See
if you can drum up some interest.

Don't cut them off.
The etching primer is thick enough that you lost the clearances for a slip
fit.
During the assembly you probably scrapped the paint enough to cause galling
(or little paint rolls) which has locked it up.
Clean off the primer, I would use a spray of acetone to clean the inside of
the
tube from the rear. That will loosen the paint up. Use a fine tip heat gun
and heat the frame only where the interference is. Etching primer gets soft
at about 200F (just to a sizzle when water put on it is enough). That will not
hurt the tubing or firewall. Remove the heat and use alcohol to cool the insert
then tap again. If it moves in go ahead and try to move it in further or
make an extraction tool.
I made the same mistake on one aircraft and had to put a painfully long screw
(5/16 inch with a washer head ground to fit) inside the gear frame tube but
large
enough to catch the insert wall. I then borrowed a slide hammer to extract
the insert. Lucky for me it was only in about an inch. But it still requires
removing the bolts from the frame, machining a bolt head which will fit your
slide hammer, replace the frame bolts, and then heating the stupid thing,
cooling
the insert and then pull it out.
Now I just ream, squirt with zinc chromate or the Corrosion X (ACP or ACF 50)
and tap it in wet and recoat front and rear to seal it in. If you put primer
on both the parts and let it dry, make the paint thin and use the ACF 50 as a
lube as well as for anticorrosion.
Hope it helps.

Subject: Europa-List: Mod 72 Debacle
Suppose that you were doing Mod 72 and it was going to be really easy as you you
are still building and haven't got the engine attached.
So, suppose that you have borrowed the club reamer and opened up the tubes in
the
undercarriage frame and cleaned them out. The unpainted inserts could then
be pushed in by hand until only about 1cm was showing.
Suppose then that you were rather enthusiastic with the etch primer and after it
had dried, tried to push the inserts in. Having got them half way in with a
hammer, what would you do if they really really didn't want to go any further
in? I mean hitting them with a hammer via a block of wood is just splitting
the wood.
What would you do? I doubt they are going to come out. Should I hit them
harder,
heat the frame, pour acetone down to remove the etch primer or just wait for
the ACF 50 to work it's way through and try again?
Any thoughts would be more than appreciated,
Thanks,
Phil
