Does anyone have any suggestions as to why the boards I'm cutting are coming out crooked?

In the picture, the straight pencil lines on the two sides of the board are at perfect 90* angles to the top of the board. But look at how the cuts are bowed in the middle and wider on one side.

I checked the angle of the blade and it's tilted sideways at 45*. The saw has its own markings, but I also used a protractor to measure it.

I'm holding the board tight against the fence and the it isn't moving when the blade is going through it.

Is the board absolutely flat?

 

[jpelzer]

Did you zero the fence to the blade when it is at center?

 

[gma2rjc]

Yeah, the board is flat and when the blade is standing up straight it's set at 0. I used the protractor to check that too.

Maybe your protractor is broken? :laughing: j/k

Is there any play (wiggle) at the pivot point between the saw and the base?

Are the ends of that board cut straight, or are they back cut per the picture of your saw?

If they're mitered, maybe your saw is leaning forward (the front is lower than the back) relative to the base.

Use the allen wrench and the directions to reset everything. Go to the manufacturer's website for info. Be safe, G

The bolt in the back of the saw is tight and there's no pivoting.

The edge of the board that rests against the fence is cut straight.

I'm not sure the saw is able to move forward. There is only one way to move it from side-to-side, and one bolt that loosens to allow the saw to tilt sideways.

What time did you start drinking today? :whistling2:

Did you check that your blade is 90* to the fence when it isn't tilted at all but is straight up at 0*? It seems like you confirmed your bevel is a true 45*, but in the bevel position, you're clearly not getting a 90* miter, which is messing up your compound cut. Lose the bevel, put the blade at 0* and measure if the blade is 90* to the fence.

now that's not nice....

*hic-up* I uh, um... *hic-up*....... :laughing: It's just water for me all day.

Yep, I did check to make sure the blade is 90* to the fence when it's upright.

Sure I can post a pic of the piece of wood with it against the blade.

A meth lab, with kids in the house? :furious:

 

[Jay123]

I always make mine run to the store for beer and cigs when I'm mixing up a batch. :yes:

 

[DangerMouse]

just be sure to remind them to put out any lit ones before they come back in the house.....

[Jay123]

that's the rule :yes:

Lose the bevel...

Did you check that your blade is 90* to the fence when it isn't tilted at all but is straight up at 0*? It seems like you confirmed your bevel is a true 45*, but in the bevel position, you're clearly not getting a 90* miter, which is messing up your compound cut. Lose the bevel, put the blade at 0* and measure if the blade is 90* to the fence.

Eliminate all variables::thumbsup:
Set the saw to 90 degrees using a framing square against the blade and fence, no bevel. Now make a cut on a piece of 6" wide plywood holding it firmly against the fence and flat on the table, and check it with a known 90 degree speed square or framing type square. It should be 90 degrees dead on if not, you got some justin' to do Lucy! Eliminate all variables.:thumbsup: Now set the bevel to 45 degrees make a cut, flip one board and join them together to see if they "mate" bevel to bevel. If they don't fit your bevel angle is off. The blade needs to be sharp or you will get "creep" in your angles and that ain't good either!
Try this and report on what you get. OK?:yes: bill
