O M etc , a REPLY ! .
Never Again . Muttering and fuming . . . the Plot thickens . . . read on .
WELL , Ive saved TWO OUNCES so far .
The INNER Tip was 1.55 Oz. - removed , split , hollowed . Got it down to about 0.6 Oz ,
Threw a flatish end drill bit in the drill press , with a piece of 1/8 " steel under it , at ' full travel ' ,
Proceeded to swiss cheese the surface ( carefull it was flat & square to at drilling ) ;
Further sanded 60 Wt. on end of chisel hadle for dowl/mandrel .
Drilled 2 mm the leadout guides , pushed in brass things , superglued'em to the nylon sliders . Before ( Just
) the Tip went back on . .
------------------------------------------------------------------------------------------------------------------------------------------------------------
I figure as the outers further out , a Oz saved on the inner's more'n an ounce saved on the outer . Being as its about 1 / 12 th Speed Variation factor .
One can allways hope .

Infernal Wing .
Its Possable to cut the beams for the joiners from the ribs , using a guide for the knife blade .
Luckinly , the forward face on the one in the leading edge on both sidfes , was softer than the rest , so I didnt slip and screw the sheeting ,
tho I removed all the center section sheeting AFT of the spar .AND THE ply B/C mounts in the inner .
Filled all the rectangle holes in the ribs .
The Glues not there in half the places. Just as well . Rock hard gook .
------------------------------------------------------------------------------------------------------------------------------------------------------------
Quite a bit of weigfht tossed . a few Oz. Anyway .
Glared at ply supply , in the end used 4 mm lite ply , out to the undercarrage mounts ( and pulled ANOTHER few web stiffeners off, filed , scraped , sanded flush - the spar rear faces . Left the ply 1/4 wider in the center bay ( The STREGA PLAN shows 1/4 Sq Spruce, tapered . )
And it shows angled sheetiung With Extra webs , Which Im NOT giving it - the webs there .
Aryldited 1/4 in on center ribs , spars , T E , night before last , And Joined Em , THEN ' as above ' braces .
Dickered with a few bits this morning , so LOWER Center Section Sheet can go on , run right across .
Will get some shallow ribs directly under the Fuse Sides .
Generall Idea was get wing ready , then store the sucker .
Got to make a nice bushed B/C assy. leadouts etc , yet .
Also Flaps And Tailplane , Elevators )

Bearers seem hard , and Ive committed enough surgery . Only real snot was hitting No 3 rib with the saw cutting the B/C pin ,
Wulda been easier to have removed All C/S Sheeting earlyer , but was ' exploratory ' . ( a good excuse
)
Put a 1/2 x 3/8 Oak cross brase between bearers at behind engine , trimmed the ply floor about 1/4 , the balsa 5/8 ,
Trimmed Front of bearers to same length , Another oak brace ACROSS the top of bearers at extreeme front , Ditto over Aft One .
New little balsa fillets in over the front & new nose block . ALSO 1/16 ply inside bearers so match the FSR 40 / 45 .
Dunno why I'll use this . ? Its LIGHTER than the ST 60 , smoother ? they say . And its gotta go somewhere , will Swing same props
or is good on a 4 inch pitch .
My fancy C F 3 Bl Prop matches the 2 in. N.N. spinner , but will see . Gotta do Motor Mount Pads, and nut plate things .
Gets a bit monotonous , as im Not into Superglue ecept as where a necessity .
Gotta put 1/8 Hard Ply reinforcers oveer the lite ply at the C/S for the B/C pivot .
( FUDGE , phone ( camera ) stuck on movie . or not so stuck if you knew anything about it whatsoever
Nose Block / ring engine pads & nut retainers all installed . glue drying. first underside Center Section Sheeting replaced ) .
Thanking you all for the replies .
