You can see the pendulum stroke set to 0 on the Carvex at 0:05 in the video and set to maximum on the Mafell. Not exactly a fair comparison. The Carvex has a higher oscillation per minute rate (3800 vs. 3000 on the Mafell), which would lead one to believe it would cut faster under the same conditions and with the same blade.
The blade will get very hot if the carbide jaws are set too tight on the blade. You can see a black line on the back of the blade almost instantly in the video once the cut starts which would indicate that it's not set properly. It got so hot that the blade was able to bend. You can see it red hot at the end of the cut where it makes contact with the jaws.
I think the person doing the tests needs to better understand how to properly operate the tools in order to conduct an unbiased and fair test.
Just my [2cents]
Shane,
You might very well be right.
However we were amazed what happened during our first test(s).
Especially while the 4 others passed without much problems.
Coming Saturday we will do the test again.
We will make sure to use the same blades (this time Festool S145/4) on all machines,
and before doing the test run we'll make try-out runs to make sure all the machines are properly set as you suggests.
Also coming Saturday we hope to have 2 Carvex 420 machines, to make sure the first machine was not a one-off monday morning offspring.
Just for the record: I'm a big fan of Festool and have a load of Festool equipment.
So are the others testers. We just like to make an unbiased record of the abilities of the present day top-end machines.
However, keep in mind that we are machine-users not laboratory testers.
What happens to us can happen to anyone.
I keep you posted here about the on-going tests.
If you have any specific tests or conditions, please let me know.
We will see if we can oblige, keeping in mind that all 5 machines should be equally treated.
