Hi! Luc.
Further to Nev's suggestion below I'd suggest using some copper bars as the
heat transfer medium.
I had used carefully taped cling film when I fitted mine so it came out
easily.
Of course the powder coating will increase the diameter so you will need
some clearance making to get the frame back in and it will also need freshly
bedding on the new Redux Flox mix. I also used saddle washers between the
finally positioned tube and the bolt heads/nuts.
Regards
Bob Harrison

Hi Luc,
Redux will ''let go'' when heated, take the bolts out, grind [dremel] as
much of the Redux away as you can to begin with.
Tie / chock the fuselage so it can not move forward, get webbing straps on
the top and bottom members of the frame hooked to a car or something heavy.
You need 4 pieces of steel bar that are a tight fit in the mount tubes, that
stick out the front by about 4'' when fully inserted.
Mask the fuselage areas close to the exposed bars with box card / alloy foil
/ sheet steel WHY and get the bars hot with a propane [ or prefereably an
acetalyne] torch.
Have wet towels ready to cool any areas of the tunnel you see getting warm,
but with a fast application of heat to the 4 bars the Redux will go soft and
with tension on the webbing straps, tap with a soft hammer, the frame will
come out forwards.
Keep the frame square as it moves forward, otherwise it may jam up.
When it is out, quench the tunnel area with the wet towels.
Nev.

Subject: Europa-List: Need help with removal of landing gear frame
While my engine is unmounted for some work, I would like to tend to the
corrosion issues of my plane.
Among others, I would like to remove the landing gear frame to get it
sandblasted and powdercoated. However, it's not only held in place by 8
bolts, but also by a green-ish cement, which I presume is a mixture of Redux
and flox.
Is there any trick to ease the removal of this frame ? Any way to soften
the cement without damage the fuselage ?
Luc
