a few thoughts on power tool threads
With reference to recent threads mostly about power tools and the
price verses value issues that always seem to arise I thought I would put down a few words and it isn't pro or anti any one person just a few observations in general The constant things in these threads is, is there a need to go for the best as in specs or best as in value for money The answer is there isn't one simple answer If specs were the be all and end all then why do Makita/Dewalt still sell 9.6 volt tools when there are higher spec'd 24 volt ones around. Why do they make different rated tools in each voltage band, why do some come with 1.3 ah batts when 3.3 ah batts are available If all you do Diy wise is the odd shelf or putting up hanging basket brackets than a 300 quid plus Makita cordless isn't the tool for you. That's more like a job for a 20 quid powerdevil from Argos hell its will even probably come with a selection of wall plugs ,drills and screws for you to do the jobs with! That doesn't mean that the mak can't do the job it just not the most sensible purchase in that instance If you have a 10' by 10' lawn in the back garden you don't buy a sit on lawnmower If you have to polyfiller a few holes in the plaster before you paint then you don't need a random orbit or belt sander If you have to cut up a few battens for a shelf in an alcove then a sliding compound mitre saw isn't needed Conversely going on price If you are building a kitchen extension a power devil drill wont last long Cutting an acre of lawn isn't a job for a flymo If you are going to have to sand down a whole house worth of doors skirtings etc you aint going to do it with a sanding block If you are going to be putting down a hardwood floor with wide boards you are not going to use a 30 quid mitre saw from b+q If drilling a hole in a wall for a wall plug then a power devil is going to be easier than doing it with a handdrill, an 800 watt drill will do it quicker than a 400 watt one , a challenge sds drill will do it quicker than a 800 watt, and an under £80 jcb, bosch etc is an lot easier to use than a challenge, and a top of the range dewalt /Makita will again be lighter and easier to use Does than mean if you don't own a dewalt/Makita SDS that you can't drill holes in walls? I suppose it comes down to why you DIY Some people do it to save money get the job done as simply and cheaply as possible, and some do it themselves so that they can have a real top notch job done with the highest spec'd items. and every variation inbetween. It doesnt make one approach better or worse than another it's just a different approach the one the suits that persons needs or wallet at the time. I have a performance power 1/4" router and have for many years, has it fallen apart no, can it trim 3/8" from the bottom of a hardwood door yes, ok I may have to take more passes then a 1/2" trend but then its was a fraction of the price, it certain mortised out for the hinges a hell of a lot quicker than doing it with a chisel, would I like a 1/2" inch trend yes for sure who wouldn't but until I need one I'll keep the PP one On the opposite side I have a 30 quid 12v cordless drill that now isn't up to the jobs I would like to do with it so am looking around for something beefier For wood chisels I have several good ones that take a good keen edge and a few from poundland. I use the ones from poundland for rough work and doing things where I wouldn't risk a good one does it make the poundland ones that will not hold an edge crap no , does it make the better ones to highly specified no, you use the tool that is appropriate for the job. Well that's my tuppence worth Steve I know this post has been posted before had problems since switching to broadband with newservers and on checking google found the posts couldnt be seen |

COST BENEFIT ANALYSIS. It's really that simple, what does it cost in every sense, and what benefit do you derive from it? Should I buy a 60K brand new Merc with 6 years full warranty, or a 600 quid old banger that will get me to the shops and back for a year before being scrapped? Only I can answser that. Because its down to the miles I might do, my perception of the value of a shiny new car in the drive versus a rusty old banger etc. So its a totally silly question, It had to be in the first place as I looked at the legnth of the DeWalt thread and the number of posts by IMM. And ignored it. |

That is sad. You are now far less wise than before. Reread the thread 4 times, and all my posts 6 times. It is for your own good. |

If specs were the be all and end all then why do Makita/Dewalt still sell 9.6 volt tools when there are higher spec'd 24 volt ones around. Why do they make different rated tools in each voltage band, why do some come with 1.3 ah batts when 3.3 ah batts are available Because for some tools, 9.6v may be enough. For example, I have a Makita angle driver which is highly geared. This does not need to turn rapidly but does need good torque, so 9.6v through a gear box is a suitable approach. Look. Its all tosh. You can get as much power from a 3v motor as a 300v motor. You just put less turns of thicker wire on it. All this 'voltage' ******** comes from the days when you had crappo SUB C cells that could do about 10 amps a piece at 1.1v roughly. So you HAD to use more cells to get up the power. Now you can get - as has been remarked - 3300 mA/h cells that have been clocked at a little short of 100A. So the voltage has become almost irrelevant. In terms of power production. Of course in terms of competitive marketing to dimwits like IMM its probably highly relevant. 'Goes up to 11' and all that. :-) What are you babbling about? You have been drinking the afternoons again haven't you? As far as torque goes, that's why god gave us gearboxes. I am not saying more. Best not, as gearboxes are unnecesary with electric motors if the motor is designed and sized for the work in hand. They are also energy consuming. There is no need for them in cars if the 4 stoke engine is dropped and eectronics take over the engine management. Using valves activated by soleniods not a belt from the crank, on a 4-stoke, the timing can be so that torque is delivered exactly where and when, eliminating a gearbox. If the efficiency of the IC engine is improved enough, ior a Stirling used, it may be used to power an alternator that powers small electric motors on each wheel. The electric motors are then the "gearbox". |

Variable valve timing for IC engines isn't new, and yet those cars which use it have *more* gears than ever before. If the efficiency of the IC engine is improved enough, ior a Stirling used, it may be used to power an alternator that powers small electric motors on each wheel. The electric motors are then the "gearbox". No they aren't. They become the drivetrain. You plainly think that anything electrical is 100% efficient. This doesn't surprise, given you don't understand it. An electric motor with a wide speed range will have varying efficiency at different speeds. -- *Also too, never, ever use repetitive redundancies * Dave Plowman London SW To e-mail, change noise into sound. |
