RE: BEGINNER'S BUILD - Tower Trainer .40
Started up again after a short break to take care of other projects, but here I am at this point:
1) Wing dowels temporarily installed.
2) Wing set in place and rubber-banded on for the next step.
3) Checking the stabilizer/wing alignment. Looks good to me.
4 & 5) Manuals (as does most kit manuals) tell you to use a string to measure the alignment of the stabilizer but I do NOT like to do it that way as I find that way to not be accurate as string stretches. I find my adjustable laser tool to be extremely accurate - the head moves left-to-right for angled measurements which is great for measuring the stab tips. The base of the laser tool is marked off in measured 5 degree increments ranging from 0 degree (center) to 90 degrees both left and right (see photo 12)
6) Checking the right angle.
7) Checking the left angle, making sure it is the same as the right measure. PERFECT.
8 - 11) When the stab was perfectly aligned I tack-glued it in place with medium CA. Then went all over the joints top and bottom and inside the fin slot with plenty of 30-minute epoxy, being careful not to glue the fin slots in place yet. The stains you see on the edges of the joints is rubbing alcohol to wipe off the excess epoxy.
12) My laser tool, extremely accurate. I wouldn't measure these alignments without it. Better than the stretchy string and easier to handle than a measuring-tape.
