g gear frame geometry=0A =0A=0AReference the landing gear frame, I recall m
aking up a redux flox mix and bedding in the tubes, so that the load were b
etter distributed. I intend on plugging the ends, probably with timber dowe
ls prior to drilling and final attachment, so I can tighten the bolts fully
without deforming the tubes, plus also it stops CO2 ingress into my tunnel
area.=0ARegards-=0ATony Renshaw-=0A=0ASent from my iPad=0A=0AOn 19/04/

st message posted by: Rowland Carson <rowlandcarson@gmail.com> I've made a
big hole in the firewall and am trying to get my landing gear frame =0A(LG0
1/3) aligned with the firewall according to the manual page 21M-2. That =0A
calls for 3 tubes (top horizontal and 2 vertical side ones) to be between 1
mm & =0A3mm from the vertical face of the firewall. After some fettling of
the holes and tunnel radii the frame goes in without too =0Amuch effort, bu
t when I sight down the firewall for a rough check of how far =0Aaway the r
elevant tubes are I find they do not appear co-planar. The top tube is =0At
oo far away at the starboard side, but the starboard vertical tube is almos
t =0Atouching the firewall. The top tube is about the right distance from t
he =0Afirewall at the port side, but the port vertical tube could stand com
ing a =0Alittle closer. Oh, and the bottom horizontal tube is pretty much p
arallel to the =0Afirewall. The fuselage bottom moulding is sitting on a do
lly that provides =0Asupport for the curve of the underside and I have not
observed any measurable =0Atwist in it. I took the LG frame out and checked
the parallelism of the tubes in question by =0Alaying a steel flat diagona
lly across (the piece I had wasn't long enough to =0Astretch from side to s
ide or top to bottom); it rocks audibly on 3 out of 4 of =0Athe combination
s. My digital level also shows that the top and bottom tubes are =0Aabout a
degree different from each other and the side vertical tubes are about =0A
half a degree different from each other. Is this significant? Should I ask
for a replacement LG frame? My next step, if no other advice forthcoming, w
ould be to try setting the =0Aalignment with the swinging arm LG02 fitted t
emporarily, and accept whatever =0Amisalignment the tubes have with the fir
ewall. in friendship Rowland | Rowland Carson ... that's Rowland w
