Kapex stops mid cut

[DrD]

Let me first say I really appreciate my Kapex.  Although I am just a hobbist I have a lot of experience with SCMS, chop saw, and such.  I was cutting 2 x 10 pine for a table top and mid way thru one of the cut the blade stops.  There was no apparent pinch, nor other tale-tale signs; immediately prior to stopping, there was a slight perceived increase in resistance to pushing thru the cut, but only slight.  I release both triggers, raised the blade, moved the blade back to the beginning of the cut and repeated the cut - no problems.  I made several subsequent cuts with no issues.

I assume the issue is with the operator, not the Kapex.  WHat might be going on.

Thanks,

Don

Before you read my suggested answer to your post, I am a 6 year user of a Kapex and I subject it to wet 2 x 12 PT pine all the way down to shoe molding.  I bought my saw to work and I use it for everything.

Honestly I think that the best approach is to cut that in two steps or really slowly.  Between moisture and pent up pressures in the wood it usually doesn't work well in my personal experience in your situation.

The stopping could be a sign of a bind due to internal wood pressure or it could be the saw's electronics cutting in to protect the saw.

Thanks Peter, it crossed my mind that there may have been some type of internal (to the pine board) pressure relief.  I was taking the cut slowly, but perhaps not slowly enough.  Good insight/advice. 

Bye the way, of my limited collection of Festools, the Kapex is the one I enjoy working with the most, and have totally dedicated the CT26 to the Kapex.  I know it's not green, but for my other tools I'm using a non AS Bosch 50mm hose (with Bob Marino 27mm adapter hose where necessary) connected to a Ridgid wet/dry vac.

Thanks, Don

2x Pine is always an interesting experience.  Don't tell anyone but I use a non-Festool hose with my setup (its orange).  The Kapex doesn't care what is sucking the dust away.  Your ears might though.

After you experiment please let us know what works best for you please.

Noise isn't of particular concern to me.  I'm virtually deaf in both ears with a constant loud ringing - comes from having too much fun with handguns and short-barreled rifles, all without benefit of hearing protection.

Bosch makes a 50mm hose?  Do you have a source/link on that?  Can't seem to find any info online.

When I planned the edges of that 2x pine with the EHL65, the pine was fairly well behaved.

I'd like to hear more of your experiences working with the 2x pine, as that's about all that's available here in NE Mississippi.

Hi Edward,

I could be wrong but I guess he refers to the 49 mm hose, Bosch# 2607000167

Kind regards,

@ Edward A Reno III

Good evening Edward.  When you get to be my age the mind becomes a dangerous thing.  What I was supposed to type was a Bosch VAC005 35 mm - between brain and fingers things got really twisted around.  So, it's a nonAS 35 mm hose.

Edward, I really appreciate your posts on the QSWO bath cabinet and your set building experience earlier this year.  I enjoy your work and the way in which you write about it.  Looking forward to more of your posts.

I have posted this a few times now, I bought some of my hoses from Stihl.
If you want to save money, Stihl is the way to go.
They are AS, and can be orderd to any size, read ANY size and extremly cheap.
The 50mm for example cost 8,30€ per meter excl. VAT.
The 50mm twist coupling cost about 5€ excl VAT.

What I know is that Stihl carries 27mm, 32mm, 37mm and 50mm hoses and have adapaters for hooking up hand tools as well.

It was quite a search to find a dealer who would help me and knew enough about the vacuum/cleaning line of Stihl, most only carry the garden stuff
But I found a good dealer now and the hoses are great, but than again its just a hose.....

I do not have a Kapex.  I do own a SCMS of another brand and had owned a RAS for many moons before the SCMS and table saw persuaded me to abandon the RAS.  I used that RAS for everything that it was acvertised for. I never cut anything thicker than one inch lumber, either crosscutting or ripping by cutting all the way thru with the first cut.  I just got into the habbit and have not tried to break the habbit.  Even using my TS 55, I still make deep cuts in two passes.

Even with making two passes, I have had my RAS come to a stop from overload.  Sometimes, just back the blade out of the cut is enough to allow the saw to cool down the overload and it was good to go.  Someimes, it meant time to do something else while it cooled down.  Once I got an electrician into the shop and redid the old wiring and upgraded the box to 200 amp with 20 amp circuits for tools, all that problem stopped.  There has been a lot of discussion about saws breaking down and I am wondering if too many cuts in thicker boards are being forced.
