Does the Carvex get hot?
« on: July 15, 2021, 10:28 AM »
I'm looking for a jigsaw that can handle hours of continuous cutting of 4/4 hardwoods. Without getting hot.

The Bosch JS572EBK is a great saw, but gets so hot I have to keep taking breaks. Even wearing gloves isn't enough. It's a wonder it doesn't shut itself down. I've got a handful of different blades to try from.

Would the Carvex, Mafell, or other option be up for this? For my application a bandsaw won't work. I don't mind stopping once in a while, but with my Bosch I'm stopping every 5 minutes.

If the Bosch can't handle this, I can't imagine a saw that can. I certainly wouldn't try the Carvex instead. Dunno about the Mafell though, I got no experience with that one.

But, sawing 4/4 hardwoods for hours after eachother, are you sure a jigsaw is the proper tool for the job? What kind of things are you making, what kind of shapes do you need to saw? Some kind of circular saw / table / slider seems to me like it could handle the long duration a lot better.

I use the jigsaw to cut flowing lines from multiple pieces made into a larger panel:

Bandsaw?

Will be much quieter as well. ;)

I would but the method used for cutting these doesn't allow for it. And trying to cut exactly to a line with a 7' board would be really hard.

Yep, that sure is hard to do with anything else than a jigsaw.

My solution would be to get multiple jigsaws. At least 2, maybe 3. Maybe 4. I don't know, give them plenty of time to cool down while you use another.

I do know my Trion does get hot. But the Carvex will probably not run as hot as it has a more efficient brushless motor. Less waste = less heat. But I don't think any jigsaw was designed with your usecase in mind.

The Bosch isn't brushless right?

Either way; they all have a fan, that will have influence too.

Multiple jigsaws might be the way to go...or this!

Bosch 7561-118 pneumatic jigsaw. $600, easier on the hands, avoid buying multiple jigsaws...but will have to add a bigger compressor to my cart...

From what I can see, pneumatic tools are going the way of the dodo. Corded isn't half as annoying as 'pressure-hosed'. Even in factories where pneumatic tools are used a new use-case is often easier served with yet another Bosch GSR 12v-15 over adding another compressed air hose on a reel.

Get a Mafell.

I was recently doing a lot of cut outs in 4/4 walnut with P1CC and I couldn't feel even the slightest resistance. It was like going through cardboard. Mafell eats it for breakfast. And the cut quality is amazing. Of course I wasn't cutting crazy fast, just as fast as I could to precisely follow my lines.

Here is an example of a hand guided straight cut with Mafell P1CC in 4/4 walnut. I could not get this quality of cut with any other jigsaw, Carvex included.

That one's not easier on the hands, that body is terrible. And you always have to hold the lever.  Noise of the compressor will also irritate incredibly. $600 for a saw and a new compressor, that's gonna add up. For that money you can buy 2 Mafell jigsaws and feel like you're in heaven.

The answer to your question is = Mafell P1CC. That is all. As an added bonus, your cuts will be 100% square to the surface. No leaning, no blade wander, nothing. Use a down-cut blade and turn the pendulum action to zero.

I'm also of the opinion that having more than one to deal with the length of work time you need is the best solution...while cutting with one, the other can be cooling down. Tools like this were not likely ever designed for continuous use. Per my recommendation at that other place, I'd stick with the same tool so the function and feel is the same as you switch between them.

Yeah a couple saws is the way to go. The Mafell also gets hot as do most barrel grip saws. I like it the best. A top handle might help you endure long sessions better.

This is very helpful info. Anyone else have the Mafell and can comment to its heat buildup over long use?

I don't know the Mafell, but it is just a law of nature that tools get hot.

Lots of movement means lots of friction, which means lots of heat. The Mafell might be a good saw, but it doesn't have a magical fridge on board that other saws don't have.

Hi Jonathan - ignore the ludicrous 'two saws for use whilst one is cooling down' posts. Or maybe these are coming from the lottery-winner guys who have two of everything - just in case. Two Fisker-Galpin Rocket Mustangs. "Yeah. I bought another one just in case the first one's ashtray got full or the windshield got a splattered mosquito on it" ......... 

Everything with a motor will obviously get warm to some degree. My experience (based on 3 years use/abuse/torture of my P1CC) is that it never gets hot enough to make me feel that it's getting outside of its comfort zone. I've used it on numerous site jobs, cutting multiple birdsmouths in 12" x 4" roof rafters with a 150mm (6") long blade on roofing jobs for maybe 4, 5, 6 hours - literally nonstop - and it was barely warm to the touch. It obviously has a lot to do with the blade, material type, cut type (rip or crosscut), and quality of cut you need - faster/rougher or slower/finer. Everything the company makes is aimed at the pro user and is over-engineered accordingly. It's a stunningly good jigsaw which really sets the bar way high. The real competition-killer is the blade clamping mechanism. It's literally the only jigsaw out there which delivers cuts which are consistently 100% square to the surface. It works with all standard Bosch-type bayonet blades, and Mafell also make a specialist blade called the 'Cunex W1' = 2 x blades welded together for ultimate stiffness and day-long use without machine fatigue. Seek a P1CC out and try it if you can. It even comes in a proper T-Loc Sys 1 Systainer instead of the new Sys3 nonsense ......... 

Oh - and I checked out your website. Lovely work.

Cutting 2x material the P1cc gets mildly warm where you barely notice it.
Cutting 5/16” thick aluminum it gets a little bit warmer but nothing excessive or a need to glove-up.
Putting it another way, I’ve never thought about it before until you brought it up and then I had to think hard about it.

On the other hand, the original Fein multi-tool with the aluminum body/head was a glove-up tool and I’d be prepared every time I used it.

My apologies, I didn't realise I had to take into account the abject poverty of the average FOG user. I realise now I was way out of line if a $300 jigsaw is as far out of reach for you as a $120.000 car.

I was merely under the assumption, considering the average tradesman here can easily have €20.000 of tools, that if you use a saw for 4 hours a day, it might not be a very bad idea to have a couple of them.

If you like your current jigsaw then I will agree that a second might be the way to go.

Otherwise the Mafel receives universal praise.

I don’t believe any of the other examples given here compared to the 7ft highly accurate rip cuts you are doing, so bare that in mind.

‘Non-stop’ cuts on a roof presumably don’t compare as they’re likely;
- often more cross cuts
- soft wood cuts
- not actually non-stop cutting (how would that happen on topical a roofing job?)

Good luck & Nice work👍

For a business operation, having redundant tools isn't a luxury. It's a necessity in many cases, so the suggestion from many folks to leverage multiple tools for continuous use isn't out of hand nor the realm of a lottery winner. I'm mostly an avocational user with some commission work. Even so, I have duplicates of certain tools because it provides advantages functionally. For a business, it does that plus insures that paying work can continue. The OP is doing some extraordinary work with the jigsaw that takes a lot of time to complete. Delays for cooling, regardless of the tool brand/model, have impact on paying productivity. So I stand by the recommendation of multiple tools for this kind of situation.

Thank you, you're absolutely right. However let's keep things more polite. You're right too, but in the grand scheme of things, you'd have to quadruple that number and then you'd be close, for a single-member shop such as mine.

I was wondering the same thing. Cutting birdsmouths or roof work or pieces of metal here and there is not what I'm doing. There's probably down time in between the softwood framing cuts. Even a minute or two helps the machine cool.

This is spot on. And something that a lot of hobbyists are unaware of. And which is why I hesitate sometimes to post Qs on forums because I don't know what angle the responses will be coming from.

I think you should get a second saw. I have 3 or 4 going at times. Different blades and set up not unlike a router. I do agree with the statement about Mafell being over engineered. I find my Mafell  tools are built for rugged use and accuracy and they are a pleasure to use. That said I have also been very happy with my cordless Carvex and Trion jigsaws.

As this is a jigsaw thread, I will mention that as someone who has used many pro jigsaws (never the Mafel) and owns both the festool jigsaws. . I think the Trion is the best by far, I’ve never understood why it seems so undervalued in the festool line up. The blade alignment does need setting properly for the blade thickness, but once that is done it is so smooth and accurate I can hardly believe it.
Even after a decade of ownership mine still surprises me when I pull it out for the more ‘serious’ jobs, over the convenience of my 18v Carvex. Carvex is still a lovely saw, but that Trion is WOW.

One day I’ll get to try the Mafel and see if really is THAT special :)

Yea, mine is a Trion barrel grip from the mid-2000s. OVer the years, I really only used it as a problem solver but sometimes that got to be creative work, such as sculpting a faux natural edge to replace rotted-beyond-salvage sapwood on the very cherry surface I'm typing on top of "as we speak".  The tool is getting used a lot more right now because I'm in a temporary shop space at our new property until I can build a building. My whole Festool arsenal use is kicked up a few notches because I had to sell my slider due to space constraints and not wanting to pay to move, store and move again a 1500 lb machine. So the Trion, track saw and my bandsaw are going to get a workout for awhile for things I can't or don't want to do on the CNC. The Trion is a beast and works very well.
