Hi to you all

I suppose I am the worse sort of FOG member. I have lurked in the back ground for a good while taking knowledge and insight from you all but putting nothing back. After Mathews call for lurkers to become contributors I through I would give it a go.

I have the good fortune to earn my crust in the woodworking trades. I think you could describe me as a cabinet maker come joiner. I take on such works as high end kitchens through to bespoke furniture/cabinets/shop fittings to commercial refurbishments. I find I am doing more and more on site manufacturing. I find the Festool System invaluable in my work; it?s like taking a full shop onto site.

Festool in my opinion make some of the best and highest quality tools available but they are not perfect.

In the next few months this site will be inundated with post with Kapex in the title, it?s started  already and you chaps can?t get your hands on them till the 1st of July. Everyone seems to be waiting with great anticipation and high hopes for the Kapex. I hope you are not going to be disappointed. I would like to put back into this site a little and share with you some observations on the Kapex.

I have had the Kapex for some time now; I think I bought one of the first few released in the UK in summer last year. I have just about used it every day since, so I must have hundreds if not thousands of hours using it. I have used it for cutting just about everything  from 300mm by 75mm laminated European Beech beams to 6mm softwood quadrant beads. A long the way its cut plastic pipe, aluminium trims, high pressure, laminates, hardwoods, softwoods and acrylics. It has taken every material in its stride and produced fantastic accurate cuts, time after time.

It is the best CMS I have ever used and I would not be parted with for anything but it?s not perfect it has some idiosyncrasies that I think you may like to know about.

Ok let?s get on with it. Your Kapex arrives in its big box with the nice pictures on the side. You unpack it put on the bench and there it is the object of your desire. You stroke it, release the transport tie down. Look at all the green bits; you already know what everything does because you have been on the net for weeks researching it. You go for the first cut. Now reality kicks in.

You will be lucky if the laser is calibrated right. I know a few lads with a Kapex and none were spot on out the box, my dealer has not had one spot on yet either. You can calibrate it yourself by poking holes in the decal on the side of the motor housing and fiddling about till it?s correct. It?s no big deal. I know that the line on the left is correct on mine and the one on the right is off by 1.5 mm with a little practice you can split the line first time.

Next up is the fence; put loads of dry lubricant on it, then drive the small stop screws in the back down so you can slide the top fences of quickly as you will have to do it a lot if you are bevel cutting. Don?t be surprised if after a few weeks, months the fence ?fires? together solid. Mine did Festool replaced the full fence no problem. Unless they have redesigned it or changed the material grade I think some of you may have this problem.

Table inserts have a little quirk as well, they grow! You will get your pride and joy out one morning and find the table inserts have now gone all wavy on you. It?s not a problem. The fix is simple take out the insert pare it down in length a little give it a bit of clearance as well. Then elongate the holes for an aft. Re attach problem solved.

Small mouldings can be a bit of a problem. The Kapex has a habit of smashing them rather than cutting them. It does not happen all the time but on hardwood it can be a bit of a problem. It also is very good at turning the small off cuts into ricochets. It took me some time to work out the cause of this (this is only a guess on my part) and the solution that works for me. Think the cause is this. If you look at the orientation of the saw spindle to the teeth on the blade and then where the teeth cut through the section of the fence right in the bottom corner. You will see that the teeth are going up and back. I think that it is this that lifts the small moulding and if you have not got the thing clamped down, it flips it up and smashes it into the body housing. Hope you understand what I am trying to explain. If you have a convention CMS to compare it to you will see what I mean. The solution is simple either clamp small stuff down or do what I do and use a loose flat fence to bring the small sections forward so that you are under the spindle at 90 degrees and the teeth are going in and not up. This spindle, teeth, fence thing also has a bit more of a serious side.

High Cuts, what I am referring to is the special cutting position. This is a great idea, works great but you have got to take care and be aware of what is going on with the sawing action. Firstly when you engage the latch at the back (to put the saw head into the high cut position) make very, very, very sure that it is fully engaged and locked. The locking mechanism can be a bit temperamental. If it?s not fully locked and secure DONT cut in this position. If it?s not properly locked and you do cut, because of the direction that the saw teeth are travelling (bottom to top in this position). The Kapex will pick up the work piece and smash it into the housing and back at you! The other thing to be careful of is the little quadrant off cut you get from cutting a mitre on the first edge of a square end. This gets picked up and shoots straight into the housing. I now either nibble away the first mitre kerf thickness at a time or cut the mitre further down the board so the off cut cannot lift. I managed to smash the saw head housing because of a faulty locking mechanism that did not fully engage. Replace by Festool under warranty.

After reading the above if you are asking the question do I still spend all that cash and get one?

The answer is YOU BET.

It is a very high quality saw the cut and accuracy is unbelievable the cuts are almost polished. Its well made in quality materials and built to last. If it?s going out to site in a truck or van it needs protection so make a box or get hold of one of Festool`s  transport container. It is a precision instrument and needs some protection and looking after.

All the other things it does are brilliant. The trenching mode is a joy to use. Even the plastic clamp that looks iffy is great.

Basically the Kapex is the dogs dangly bits.

Go get one you won?t regret it. Just be aware of the above.

I hope you understand what I mean in some of my descriptions, I am not as eloquent as some of you guys on here. I will do my best to expand on any of the above and try and answer your questions but be patient. I am a computer idiot and type about 4 words a minute.
Regards to you all

Ps
you soon get used to the saw grip
 
John thanks for the imput.  I am waiting for my Kapex and will pick it up 1st thing in the morning 7/01.  My Makita is not fit for duty any longer.    I plan to play with it and "force"  it to replicate the problems you described.  I would much rather have minor adjustments to perform in my home shop than on the job.

Thanks again for the heads up, Dan
 
Hi John, I'm not the official greeter but welcome aboard anyway.

As a long term user can you tell us anything more about the blades specifically like which do you prefer and how long do you feel they stay sharp etc.?

I was a little miffed when I learned of yet another exclusive part for something like a saw blade.
 
Welcome John. I've had my Dewalt 12" CSMS blow small pieces into smaller pieces. The problem I found was I am starting to cut slightly before the blade is at full speed. I don't know if this may help but I will say, it scares the potatos outta me when it happens. Unfortunately the only way I'm going to be able get a Kapex is if I win it here. ;D
 
John,

Did you have any issues with your Kapex miter table being hard to turn?

Thanks,

Eiji
 
Hi Woodenfish,
even though i have cut diferent materials i  have used the same blade (the one supplied) it cuts just about anything very well.  it stayed sharp about twice as long as say a bosch branded blade. think the carbide is of higb q
 
Hi Bill
Tried just about everything to get round this problem different speeds , sliding the saw head in, using it as a chop saw. i don't know if my guess about the problem is correct but the loose fence thing and clamping get around it. it may just be me being cack handed. i have a friend (who is twice the craftsman i will ever be) has had the same experience. the same solution works for him to. its no big deal if you are aware. if i had to go and get another cms tomorrow i would still buy the kapex . it is that good
regards john
 
Hi Eiji
as someone on here has already said the kapex out of the box is tight. bit like a new engine. it needs to be run in a little. had no problems with table being hard to turn. you can split a degree on it very easily. this thing can cut to degrees of accuracy that i cant see.
Regards John
 
Hi Dan
enjoy your  new kapex when it comes. its dam good. the dust extraction is very good in the standard cut position, it varies in other cut modes but is still way ahead of anything else out there. if you can, use a 36mm hose. i did not think there would be a lot of difference between the standard and the bigger one but there is. its great to carry about as it is light and compact and because it has a small footprint the weight is nearer your body, so no back strain. you can carry it up 3 floors without the need for oxygen when you get to the top. if you are going to get any options, get the wing extensions with the cornice bits they work very well. the kapex just does what it needs to in a refined unfussy way its quiet and smooth. blade change is easy and the trenching system dam good. half mm precise lap joint on site no problem. when you new friend arrive it will soon become your best friend. if you want to own another remarkable Festool tool go get the of2200 , now thats something else.
regards john
 
Sorry woodenfish
i managed to loose half your reply. i did state that i was a computer idiot. it continues thus :-quality just like their routher cutter. the blade is a dead blade ie it does not ring if tapped. this makes the saw very quiet in use. my festool rep told me the blade was designed along side the kapex. who knows could be bs but it`s a good blade. off topic the rep also told me that festool has set up an assembly line in the US just for the kapex.
regards john

Wow, all this for just $1300.00!  :D Now I know what I'm missing on my DeWalt, to think I could have paid more to have all this.  ;)
 
John,

Thanks for all the details. Good to read the good, the bad and the ugly. Welcome and keep posting. ;D
 
Windmill man, I too appreciate your post.  It's good to have a review  up by an everyday tool user. 

I hope Matthew will copy it to the section on tool reviews.

I'm sure the Kapex is a wonderful tool.  I'd bet the dust collection is as good as we expect from Festool, nice for onsite jobs.  I like the idea of taking the angle gauge and transferring the angle directly to the saw via the laser guide.  I hope it works.  ;)

I am, as always looking at cost vs the tool.  $1,300 USD is a lot to pay for a tool that isn't ready to go to work out of the box.  I have an older DeWalt (about 15 yo) that I use to cut crown, trim, picture frames and x-cut hard and softwoods.  I let my kids at school use it , it's survived them too  :o (OK, I was hovering over them though).  I think I'll keep it.

Thanks Steve, that's a good idea.  If Windmill Man wants me to, I will gladly move this to the "Tool Reviews" area.  I try to defer to member wishes when making such moves.

What do you say, Windmill Man?

Stay in touch,
Matthew
 
I think this is the right place for Windmill's thread. It's not a review and besides it will get more attention here than in the tool review area. These is the kind of things people want to know about and the discussion going on is a good one, let keep it in the place where the most people will see it.
 
Hmmmm,

Strange, mine was spot on right out of the box.  Miter settings, bevel settings and lasers were all right on.  Fences move smoothly and the accessory tables go on and off with no effort and wind up dead flat no matter how many times I have removed and remounted them.  Rotation of the table for miter settings is reassuringly snug, but not tight, and can easily be set to whatever angle one needs.  Rotation of the bevel is the same and aided by the micro adjust knob. 

In setting mine up on the work station I built, I noticed that if I over torqued one of the mounting bolts I could get the base casting to twist a small amount as that one side pushed down differentially on its rubber pad and that made miter rotation a bit stiffer - pilot error and easily corrected by simply tightening all the mounting bolts the same amount.

Based on my experience I am a bit mystified by Windmill man's experience (welcome to the post, BTW!).  I can't imagine a laser line being off 1.5mm.  The kerf will be 2mm to 3mm depending on the blade mounted, so that is more than half a kerf width off.  The laser line itself on mine is just under 1mm wide (~.040") and the inside edges of the two lines just under 3mm apart (the kerf width on the blade supplied with the saw).  You can be set the lasers so you cut off of either the inside or the outside of the line, your choice.  You want those lasers to be spot on.  In building fine furniture, or in doing critical work like crown moldings, an error of 0.5mm or more in the fit of a miter would stand out like a sore thumb.

If the lasers on your saw are off any at all, just clamp the work piece in place, make a partial cut with the blade you intend to use and look at where the laser lines are relative to the edges of the kerf you just cut.  Adjust to your liking (a less than 1 minute adjustment) and you are good to go.  It doesn't make sense to me to have precise laser guides, leave them out of adjustment and try to remember which way they are out and by how much every time you make a cut. 

Hope this helps.

Jerry
 
WRT the lasers -

Windmill Man states he got one of the first ones in the UK, as did I. The laser was susceptible to coming out of adjustment if knocked during transport, and I believe that it was re-designed to make it more robust.

In the US, you'll obviously get the newer version...
