Fliskits MACME Shrew Build, Part 6, Tube Marking and Cutting

On the first try, I didn't mark the long internal engine mount tube with red and black lines. (Parts 4 & 5)
Heck, I'm stuck in Mexico and don't know where to find the fine tip pens.
I used the instruction drawing and place the centering rings by eye.

Trust me - Mark the tubes with the red and black reference lines!
The tube segments and their placement will be easier with the lines.

These are the pens to use - Ultra Fine Line, Paper Mate Flair style pens.



The Black an Red lines are drawn on opposite sides down the length of the BT-5 tube.
To the left of the black line is a pencil line for the launch lug location.

Note: This is a white BT-5. The kit came with a brown tube. I ruined the brown tube cutting out the segments incorrectly the first time.


Wrap and tape the cutting guide tightly around the tube.
When cutting you don't want the guide to slip.

Be sure the black and red lines are lined up with the designated lines on the wrap around guide.
Start at the top end and work down to the bottom.

TIP: When cutting a small tube like this, it's easier to keep the blade still and rotate the tube under the blade.
Cut about 1/8" at a time, adjust and cut 1/8" more.
As always, never try to cut a tube with one pass. Multiple light cuts are better.
