View Full Version : Cutting Angles greater than 45 degrees..

Well, my new box for my FI Q 15 is going to require multiple angle cuts of around 56 and 34 degrees on different pieces. However, i have yet to find a table saw that cuts anything over 45 degrees. Is there any "cheat" method to get it to cut at a higher angle or anything? If not, i'm kinda scrweed..

Just cut the complimentary angle. ie 54 * cut a 36

Do you mean just cut any angle where both angles add up to 90 degrees? The only way to do that would be to use 45 and 45, and would that even work..this is what im talking about..u can see where the angled cuts need to be. the person that designed my box said they need to be 56.309 and 33.690

Thats going to be a rough build. Just think about what I said and it will make sense. I cant explain much more on the internet.

What do you mean a rough build..yeah its gonna be challenging..sorta

I'm still confused. No matter what they have to equal 90 degrees. And the only way to keep both numbers at 45 degrees or less is to use 45 and 45

Say you want a 66 degree cut.... you set the blade to 24 degrees.... cut.

What do you have now..... you have a piece with a 24 degree edge....and the other piece has a 66 degree edge.

OHHH i got ya....lol. i was thinking too hard. thanks

Nevermind, i'm still confused. You make it sound like there is 2 pieces. All i want to do is cut an angle out of one piece.. *brain fart*

You cut 1 piece into 2..... piece "a" has 24degree angle... piece "b" has the 66 degree.

But wouldn't it add up to 180 degrees? god **** this is confusing

I understand what your saying, but i don't get how that would work. Say you need a 60 degree cut. You set the blade at 30 degrees like you said. Won't the 60 degree angle be on the tiny little piece of MDF that is left over?

Not if you flip the board around. I know.... just do a test cut and use a protractor to measure the angles on the 2 pieces of wood.... maybe that'll help.

Yeah, i'm goin to do that tomorrow. thanks for the help.

I think i finally understand. A 60 degree cut is basically the same thing as a 30 degree cut, just pending on which way the board is facing...right?

That explains why table saws only go up to 45 degreees..

At least you didn't ask about how to do proofs.

you and the guy who doesn't understand algerbra should get t/g

j/k glad you figured it out

mmm... can I ask a quite honest question?

Why don't you just model it with wood and then make it out of fiberglass?

This would be less cumbersum I think.

What do you mean exactly?

You can run the board through the saw 4 different ways...4 times 45 equals 180....
