Speaking of Duco has any one noticed it being thinner when it comes out of the tube? The tube I bought last week was very thin, nothing like what I remember. Ive been using it straight no thinning although it could use some. Maybe 15/85.

Vlad,
I only add platicizer in the glue I use for gluing rolled motor
tubes and tailboom. The glue I use for that is about 50/50 Duco
acetone I mix it by eye actually and how well it flows out the
glue bottle and test it on some trial pieces of thin wood for how
well it adheres and how it makes thin sheet curl up. If it curls
too much I add an extra drop or two then test again. I use the
1/2 oz IMS Type C glue bottle and when about half full with the
Duco/acetone mix I add in about 5-6 drops of DOP as my start
point, may add a few extra more drops but never more than that as
too much will make it soak into the wood and not glue then the
mixture is useless. So I I kind of do two glue tests on a new glue
batch , one test is a drop of glue on about a 1/4 x 1/4 piece of
thin wood ~.008" with a drop of glue in the middle to see how much
it curls when drying, a little curl up is OK then I also do an
overlap test of the same wood with about 1/16" overlap then let it
dry and see it pulls right apart easy or not. Too much DOP and it
will act like you never glued it. Once you do it once or twice you
get the feel for it. I never used TCP mainly because when added to
microfilm as a plasticizer the film would eventually fall apart
over time so I figured I did not want that in my glue joints,
especially on a motor stick. The HLS I flew at USIC this year used
a motor stick I built 9 years ago and the glue joint held just
fine all these years so I am sticking with what works for me. Hope
this info helps.
