I have tried to cut my owm slots as well. I ended up with a real mess.

Now, when I have a model that really needs TTW fins, I order a custom slotted tube from BMS:

Yes, that is an option. I've never slotted model rocket body tubes before, but the trick is to stiffen up the tube. If you're slotting a 13mm, 18mm or 24mm tube, you can stick a spent motor case in the tube to help support it during cutting. Any other size tube you'll want to stick couplers in to stiffen it up while you cut.

I would most certainly agree that there are NO stupid questions here !
That was not my intent with the response.
I provided the laser answer as possibly a mis-guided attempt at humor....I still think it's funny though.
Many do cut their own fin slots, but I find it to be extremely tedious to do this accurately without at least some sort of jig.

Yes, there is such a thing as NORMAL
, if you have to ask what is "NORMAL" , you probably aren't !

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !

I understood your humor, I just wanted to make sure that others didn't take it the wrong way.

No offense taken with your reply. That was my sad attempt at humor as well. I don't think it is possible to fly rockets and not have a sense of humor. I believe I'll stick to good ole' surface mounting, seems a lot less painless.
In all my years I have only had a few "incidents" regarding fin shear and cracking. After a through CSI (crash scene investigation) it was always my fault. Come to think of it, if you build it from the ground up and bad things happen (barring a motor related CATO) isn't it always going to be your fault?
