Nice video, I'm gonna see if I can find that threaded pin he got and fix my Carvex.

I still can't wrap my head around the fact that Festool makes so much well engineered, brillaint tools, and do this jigsaw so incredibly bad.

Mind you, they soon realised how bad their first try, the PS400, was and then made their second try, the PS420 only just marginally better, but still utterly junk. It's like they're not even trying. [doh]

I saw that video a week or so ago. Looks interesting, but I'm not sure I want to dig that deep into my Carvex?

I saw it posted on the Facebook SawStop group when someone asked about the Carvex. I didn't even realize my Carvex had a problem until I saw that video. [lol]

Mine has always had the slop and I originally got it from the recon sale a few years back. A fix is in order and dare I say a factory fix from Festool on all these etc. I am not sure how that pin is supposed to stay put if not mechanically fixed like he said either with threads or glue. It's a simple enough task from watching the video but the problem seems ubiquitous.

As a Moderator I am supposed to tell all to not modify your tools or post about your modifications here.

Taking that hat off, I saw that video thru Facebook and actually ordered the pins.  They are sitting on my MFT wondering if I will use one.

My concern with that video is that it did not speak to how it affected the adjustable orbital action.  Also once that new part is put in place and if it doesn't work then there isn't a way to go back to what you had.

So in other words, I found it tempting but have chickened out at least temporarily.

Does this fix effect use of the oscillation function?

No, the osiclation function goes backwards from the point at which the blade is held in the straight position, creating the oscillating action

Can't find 4x12 screws on Amazon - closest is 4x10. He mentions 3-4 mm protruding after install. Wondering if 10 will fit?

I'm SO ready to try - if this fix WORKS it would be like getting a free Mafell with soft start and strobe light!

PERFECT - Thanx! I tried searching 11 different ways and could NOT come up with that listing.

I'm ordering now.

Right? I ordered some yesterday and was thinking the same thing.

If anyone wants one of the extras, PM me an address and I'll drop one in the mail for you.

I think I've got some stamps somewhere...

We're cleaning out my grandmother-in-law's house; I haven't seen that many stamps with actual cent values since I cleaned out the junk boxes I still had from my college dorm...  I wonder if I could put 58 of the "makeup" stamps on a single envelope and get away with it...  I think I have the 2-cent makeup stamps, too.  Those'll come in handy this July...

Excellent, thank you very much!
This item is already sold out on the European amazon webshops! I ordered a few (I have several carvex) from amazon US.
Hopefully someone can find and share alternative link to order them in Europe.

BTW, it would be nice to have the input of a Festool engineer on this issue and fix, esp. re. pros and possible cons of the fix. Please Festool managers, allow one of your technical employees to speak on this. Or could you provide a similar fix freely (i.e. through a recall) to the owners?

Gentlemen-

If you do this mod, and the blade eject jams up...... Back it off a couple threads.  JFC that was frustrating to figure out.

I also had to clearance the housing a tiny bit, the 12mm length was a little much.  No big deal.  If I take this god forsaken thing apart again, I'm going to drill a thru-hole so I can adjust the tension without disassembly.

These can be bought at numerous places with better stock than Amazon. Search for K0384.10410 if you want M4x10

Well, at least the PS 300 became cheaper after the Carvex arrived. I bought a PS 300 mainly because I was afraid it would disappear  [tongue] and didn't want the Carvex(' price tag).

Just did this on my PS 420. My Carvex is from Recon so my warranty is up soon. Why not? The trickiest part was removing the pin but otherwise it's an easy mod. And yeah, the 12mm grub is just a bit too long. I used the tip of a utility blade to carve out a hole for the extra length and to allow front access for the Allen key. The Allen head can be accessed with the chip guard lowered.

I've got lots of extra screws if anyone wants one. PM your address. @mcooley yours will get dropped in the mailbox tomorrow.

So, I own a Trion and I like it...I own a Carvex and I hate it...I also own a P1 cc and I love it. For those who've done this modification, what are the advantages? What does this modification provide that a standard Carvex doesn't? What exactly is the itch that this modification scratches?

I'll make some cuts with mine tomorrow and report back to you.

I primarily use my jigsaw for rough cuts to remove material before flushing it up with the router. When I can't use the band saw, I have to use the jigsaw. Historically, I've always had bad jigsaw technique. I can remember trying to cut out skateboard blanks back in the 80s with an old Black & Decker and I got terrible cuts then. I get slightly less terrible cuts now. I don't respect the jigsaw and it doesn't respect me ;)

I assumed the play in my Carvex was normal and I ignored it. As I watched the source video and read other comments about Mafell's jigsaw, I thought maybe something is up. So I figured I'd make the mod and see what happens.

I have low expectations. If I get cleaner cuts without the slop in the blade column, great! If not, then that's fine too. My unscientific thought is that my Carvex sounds like it's running smoother with the screw in place. However, I don't expect to notice much of a difference. I am hoping to be surprised.

Anyway, I've seen other people get really clean cuts with a jigsaw so I know it's possible. Maybe I need to practice holding it upside down?

I never could quite describe why the Carvex "feels weird".  But replacing this pin makes it feel totally different.  Definitely reduces the "I hate this thing" feelings.  I notice that starting a cut takes less conscious effort, which makes sense if the piston has been drifting the whole time I've owned it. 

I'll put a few more miles on it and report back.  But so far, it's a big improvement.  I have a Trion too, so I'll hook em both up and do a side by side.

If there is any load at all being placed on that grub screw while the carvex is working, wouldn't the threads give up pretty quickly and create another version of the original problem?

Is it just me being cynical - or is it too much to expect that a £400 jigsaw shouldn't need fixing by its owners?

And if you want clean cuts, how about using a downcut blade, a splinterguard, and backing the pendulum action way back? It all seems so simple to me ….

Quicker than the factory press-fit did?  Not likely.

Bought mine used.  If the choice is to either spend ten bucks or pout, I guess I'm spending ten bucks.

I spent a bit of time this morning making test cuts in scrap wood. As I mentioned before, my experience with jigsaws doesn't run very deep so take this with a grain of salt, but the Carvex seems to have a more stable feel to it. I backed the screw out to mimic the OEM pin location and it felt like there was a bit more vibration. The cut quality was more or less the same as was the maneuverability cutting curves.

Maybe a placebo effect? I don't really know. If you're a heavy jigsaw user, you'll probably notice the difference much more than I did.

However, the thing that really made a difference in the cut quality was also installing a splinterguard. I believe that's the key to getting really clean cuts with the Carvex and I'll have to spend more time using the Carvex now that I know what it's capable of.

If the choice is to either spend ten bucks or pout, I guess I'm spending ten bucks.

My thoughts, too. I don't feel like I've done any harm to the tool. I have the ability to snug up the column or go back to the looser, OEM setting, with a couple turns of the hex key.

I have 6 5 3 2 stamps left so if anyone wants a screw, PM your address and I'll drop it in the mail.

I do this all the time.  I will buy discontinued stamps on E-bay at $.70-$.75 on the dollar, save the interesting ones for a grandchild, and will send out envelopes with 4 or 5 stamps on the envelope at a time.  Working through some $.13 cent Christmas stamps right now.  A bunch of the stamps were from the 1950's, some even 1940's. It takes some research sometimes to figure out how to use the "F" or "G" stamps or the "add on to first class" memo stamp.

Don’t expect an answer to your question @Cheese - just as I never expected a response to mine.  It’s been my overwhelming experience on here that anything direct, anti-grey-and-green, real-world or logical will be ignored by the hobby-shop faithful who don’t have client projects to bring in on time and on budget, but who do have time to dismantle and modify tools which don’t do what they’re supposed to. I also have a P1CC which I use to earn a living, and it’s blade doesn’t wander, it cuts at 90 degrees to the surface all of the time, and it doesn’t need stamps or Chinese Amazon grubscrews so the owners can get it to work properly.

Interestingly enough - my P1CC actually broke down recently. It was eventually repaired FOC out of warranty by the UK importer, but before they played ball, I posted on here seeking advice on possibly replacing it with a Carvex. The answer from the sadly restricted number of unblinkered contributors on here was an almost unanimous ‘don’t’.

I’d rather have a mind opened by wonder, than closed by faith. If you dare to challenge the order, you’re labelled as a ‘pouter’.
