Fuselage trimming


n200qt@ymail.com
 

All, I picked up an unstarted Q-200 kit last year and now I've started to build. As I read thru the construction plans (and the few QUICKTALK/Q-Talk issues I have), I'm having a hard time locating which trim lines to cut too. I can clearly see the tape lines that were used in the molds, BUT the question is do I trim to the top of the tape line or the bottom?

Thanks for any inputs!

It's somewhere in the archives. I think you trim the tape away.

You better verify though. Look in very old QAC newsletters and issues of
Q-talk.

Here is a picture of my Fuselage Trimming:

Hope this helps.

Thanks Sam!

I think I need 'QuickTalk' issue # 10 which is one that I don't currently have. Ron Cross posted a picture that shows him "trimming the tape away" as you suggested. I'll do some more looking and see what I can come up with.

Thanks for everyone's help!!!

Neal,

Glass is best cut using a grit edged blade either tungsten carbide or
diamond work well with light feed.
Carbon steel blades designed for metal or wood lose the cutting edge
quickly due to the abrasive nature of glass. The tooth also tends to delaminate
the material next to the cut. Both hacksaw blades and jigsaw blades are
available in grit form that stays sharp and basically sands away the material.
Feeding to fast generates excess heat and can clog the grit with melted
epoxy.

Try and use a backup material to minimize backside fraying.

Neal,

I looked in Issue #10. There is a SHORT paragraph on Fuselage Trimming.
They recommend using a work/trouble light to view the tape edges and mark
it with a soft lead pencil.
They don't say with side of the tape to cut on.
They recommend using a handheld hacksaw blade to cut with. Warning that a
jigsaw will delaminate the sandwitch.
I had no problem with the jigsaw. I used a NEW, fine-toothed metal blade.
Suggest you cut a short distance then inspect VERY CAREFULLY how well it
cut before proceeding.
As with anything, talk to as many people that you can who have already
done it, and then use your best judgement.

I will look in the other issues and see if I see anything else.

Neal,

Just something to consider.....
Let's say you were to trim the fuselage LEAVING the "tapes".
The foreward edge of the forward fuselage is FS14.
The backend of the rear fuselage is at FS200.
Measure the lower-forward fuselage from the front to the rear (including the "tapes").
Measure the lower-rear fuselage from the front to the rear (including the "tape" at the forward edge).

Do you end up with a total of 186 inches? (FS200 - FS14).
Would the FS175 bulkhead fit into the rear fuselage at FS175?
Just an idea to think about.

Of course if you DID leave the "tapes" when trimming, and it does not look right, you could always recut, and trim them off.

Ron,

I'm heading to work on my project this morning and I'll measure as you
suggested. I'll let you know if that works or not.


Thanks for the suggestion.

Neal

Go down to your local hardware store and buy a "multi-tool". Fein made the original and it's still the best one out there. However, the cheaper ones (Craftsman, Rockwell, Harbor Freight) work fine. You might need to buy an after market circular blade made of high speed steel. The one with my harbor freight tool was junk. These things are the greatest thing ever for slicing cured glass. No problem with delamination and they cut fast. I love mine and use it a lot. Buy one and you won't regret it.

All,

After much delay, I was able to make it out to work on the Q. I was able to
determine that I needed to "cut away" the tape line.

Thanks everyone for inputs!

Neal Andersen

P.S. Congrats on your first flight Sanjay. I hope to follow in a few years!
