REFLECTOR: epoxy

[Benedikt Harren]

Thanks,
 
so I'll cover the speedbrake once again with fine BID, just to be on the
safe side. As far as the epoxy goes, I'll keep it to 44:100 as closely as
possible. 
 
thx again for the input.

A good cleaner that is safe for  almost all foams and epoxy is alcohol.  Its
also better for humans... I would recommend, clean with alcohol, then rough
up with 60/80 grit sand paper.

As far as the speed brake,  I gouged out a shallow(1/8") groove in the foam,
filled with flox and immediately wrapped  with 2 layers of bid.  The brake
takes a beating and I don't want it coming apart...

Dear all,
 
just came back from my shop with a  couple of questions:
I bought a STD. RG E with fastbuilt wings & fuselage. The previous owner
completed the speedbrake without installing it. He applied microglass and
fine BID to the outer edge of the speedbrake per the manual which he
afterwards sanded. While sanding he cut into the BID leaving at some places
micro only. Since the speedbrake will be out in the elements I was wondering
if I need to cover the edge with BID a second time.
 
Second, I started sanding the front of the canard bulkhead in order to apply
the 2 plies of BID as outlined in the manual. How do I clean off the sanded
areas? Cloth? Acetone? Does Anybody know whether the mixing ratio of
hardener (brown) to resin (44:100) is by weight or by volume? What is the
tolerance?
 
Thirdly, I am planning to low-cut the keel and move the seats more towards
the center of the fuselage in order to gain some "hip-room". Scott Baker
told me that the original keel can be modified. Anybody any drawings or
input on that?
 
Appreciate the help!
 
Kind regards,
