  1. Wera or Felo?

    Another thing I really like about the Wera bits is that they are numbered and color coded. This way it is much faster to find a given bit.

    So mileage is the right word then? Not distance? And no less current doesn't mean less resistance at all. The resistance will stay the same. It is a fixed variable.
  3. 10.8V now 12V worldwide

    You don't have less resistance, you have less current. Take the time to read my comments again. I said higher voltage is in theory better because it reduces heat losses. I don't know why you are arguing with me about something I already said was true. What I said that's was wrong to say is that choosing a voltage is about choosing between runtime and power. It's not because runtime, power and work are not independent variables. Sorry if it's confusing anyone. Tension is the proper term and the one we were using in school but yes it's the same as voltage. Well ok then but if you use smaller wires, you increase the resistance and therefore the heat losses. I think Dewalt would prefer to increase the runtime then save a bit of money on smaller components. I could be wrong, I don't know what their costs are.

    I was neglecting heat losses to explain the concept that power,. runtime and work are linked together and not independent variables. I don't think any engineer would neglect heat losses. That would be crazy. That's what the job is all about. I wrote the same exact thing about higher voltages in another comment, that reducing current would mean fewer heat losses.
  5. 10.8V now 12V worldwide

    The smaller cable size will rise the resistance so the equation is still valid. And I think it would be stupid to raise the voltage and then using smaller cables. Why give yourself all the trouble of using a new tension in the first place if you are going to use smaller cables? But I totally agree with you that you can't judge a tool just by looking at the claimed numbers. That's why reviews are important. There are just too many factors at play. I have no opinion on which tool is better and nothing against Dewalt or Makita. But it's important to me that we don't spread false scientific statements whatever you may think of a brand.

    Exactly, the name of the game is efficiency which basically means reducing the amount of lost energy due to heat and there are many many factors involved in that equation. Picking a battery voltage is not about choosing between power or runtime but about balancing some variables like weight, power, ... given the expected use of the tool. The reason why higher tension is potentially better is because energy losses in a circuit are equal to current² * resistance. Therefore, if you lower the current needed by rising the voltage, you are in theory supposed to get less energy lost in terms of heat. But again that's just one variable and there are other factors involved that need to be checked before coming to a conclusion.

    You will use more energy but you will get the same amount of useful work out of the battery because Work = Power * runtime - heat losses. The same job will require the same amount of energy if we are neglecting heat losses. The only difference is one tool will finish faster than the other.
  8. 10.8V now 12V worldwide

    Listen I have a degree in electrical engineering. I think I know what is power is and I know what the scientific meaning of work is. If your battery has 200 Wh of energy into it, you are going to produce 200 Wh of work out no matter what the voltage, if we are neglecting what you are loosing in term of heat. It doesn't matter what voltage your tool is. Your battery will always have the same amount of energy inside of it. You can't create new energy out of thin air just by switching the voltage. If you are drilling the same hole with a 20V or a 60V drill, you are going to need the same amount of energy (again if we are neglecting heat losses which could be higher given a more powerful tool). The voltage has nothing to do with the energy required. One tool will complete the job faster than the other but your batteries will have lost the same amount of energy at the end of the job. It's basic thermodynamics.

    It's not that clear cut. A more powerful tool will finish most of the time its job faster so you don't end up using more energy (of course some of it is loss through extra heat). The trade off is more between weight and power in my opinion.
  10. DeWalt Power Planer leaving streaks

    Totally agreed but I like the idea. The jointer is one of the tool that scares me the most.
  11. DeWalt Power Planer leaving streaks

    I know the guy from eureka zone use to do it. I always wanted to try it. Looks safer than a big jointer.
  12. DeWalt Power Planer leaving streaks

    Would it not be possible to build a sled like that but for the planer instead?
  13. New decision

    I was just thinking last week that a small 12v planer would be terrific. Didn't expect a trim router as well :-) Hopefully we get them in north america :-)
  14. New decision

    Wow sounds great. I suppose the planer will have a smaller plate. Would be perfect to do doors and countertop edges :-) Will they work with the guide rails? A rotary hammer would be great too.
  15. i hate dewalt bit sets

    They are the easiest to clean though so they make sense for decorative cover plates
