BC's KAPEX Problem

[WarnerConstCo.]

Mastercabman-  Just take a 1x8 bring it from the left, saw beveled 45 left, and just take that 45 degree triangle off the end of that 1x8.

I wouldn't try it, It broke my 0 clearance throat plate. 

Just looking at the cut, looks like it could be dangerous.

Dangerous ain't the word. I'm supprised that this problem has not been come across before. It really knocked my saw out of alignment as well. I just checked my insert on my makita and it has a gap as big as the Kapex so i don't think that's the issue. I'm wondering if the blade may be having a part to play in it. First time i have ever used a Festool blade and it's the first time i ever had this happen on any saw.

Nope, I have the tenryu 80t on mine right now when I did it.

I think it is throwing that piece straight down into the base and it is bouncing right back out.

 

[WarnerConstCo.]

There are always a few unsafe cuts on most tools, the table saw for one.

I know of a few cuts I try to avoid on my TS for these reasons.

I have had this happen with every miter saw I have ever used including the Kapex.
This is not a Kapex only issue. It is a power miter saw issue.

Wonder why on earth it's doing that. I cant see that even an aux fence is going to make any difference after thinking about it. it will just knock the saw out of alignment or throw a piece in my face. Did your main saw unti come flying back at you when it caught the off cut? Mine come back so hard that it knocked the whole saw includeing the table towards me which was why my fingers nearly ended up in the blade.

 

[WarnerConstCo.]

No BC, the only thing that went flying was the off cut, the saw didnt move.

By chance did you not have the bevel lock flipped back down?

An auxiliary fence will keep that off cut on the right from moving anywhere.

Thanks Chris, like I said I never made a cut like this on any of my miter saws I have owned.

You right i'm not going to try it,but i am going to look at what could it be with some cut pcs of wood.
I have cut some 6-7" tall laminated splashes before and don't recall any problem like that.But then again i think i was cutting much bigger fall off pieces.

I feel this happens with the kapex more because of the guard. Look at it carefully and you will see it is the cause. All the other saws I have used before I could roll the guard up so it didn't push the wood into the blade. It is really dangerous and stinks because not all the time you can cut more waste. I do alot of finished cabinet installs and I only have so much crown and I cut it on the flat and that's when it likes to happen.

yep bevel lock def locked down. Plus i had it on the 45 stop also. The one thing that did grab my attention that i should have said in first few posts was the cable tie that held my saw in the down posistion was broken when i took the saw out of the box. Not sure but perhaps this saw had a bad fall and broke the cable tie. If it broke that it could have knocked something else out also. My lasers were out about a 16th each side.

I am sorry but, I just went a did a practice right and left bevel.

In the instance that is being talked about here, the blade guard does not even touch the off cut to the right.  It is over 1/2" above the off cut.

So, I dont see anyway the guard is the culprit.

I agree, the guard isn't touching the offcut piece so it's not to blame.

Flying pieces of wood is caused by letting the saw head up to quick.

LET THE BLADE COME TO A COMPLETE STOP BEFORE LIFTING THE HEAD!!!
Small pc just get sucked in and gets into the spinning blade.

You right,its happen with my DeWalt 10" CMS,if the blade not complete stop and I lifting the head the SMALL piece is just bouncing so hard around.

Yes it does on most small return cuts.

It does not make a difference in this situation.
Trust me, I tired and it made no difference what I did that piece was going to be coming right back at you.

well,looks like operate a Kapex you need not only safety glasses but also face shield.Good job Festool!

 

[vwdave]

I am talking about the the scrap piece to the left of the blade.  Thats the piece that is getting thrown.  The guard is pushing on that piece and on the right side of the blade your right, it is off the material by 3/8".  I will see if a buddy is around and can film it for me this weekend.

Make the cut with the material on the other side.

There is more then one way to cut something, some are not so safe, some are.

I would think it is more like common sense.

 

[erikfsn]

I had the same thing (or similar) happen with my Kapex last year, the piece of wood broke the plastic piece that holds the rubber dust collector on. That lead to the three return trips to Festool that I wrote about.

I think this is just about spot on, how he had his incident.

I don't see how anything good would come of making this cut.

 

[jvsteenb]

If THAT was really the cut he tried to make, I'm not at all surprised by the fact that the Kapex did it's cannonball-trick.
But I DO wonder how anyone managed to do this with any other chopsaw WITHOUT somehow entering the projectile-phase ???

That is the cut, and I don't know either.

I tried the same cut on 3 different saws this morning and had bad results.

He said he has done it 1000's of times though without one problem on his makita.
