Electronic components requirement.
Hi.
I am fancying a little project using electrical components. I want to make a mini-mini-table saw. I've looked at the RS Components website and its all bit out there for me. I think I'd like it to run on battery power at this stage but I may be being naive. The work that the saw is being designed for cutting very thin sections of timber..2mm thick. I will build a manifold/body from acrylic or something. So what is a list of components I will need to complete this. eg motor ( recommendations on this necessary) spindle, connectors, gears, battery holder type soldering iron. soldering consumables. etc. Thanks. Arthur |

So what is a list of components I will need to complete this. eg motor ( recommendations on this necessary) spindle, connectors, gears, battery holder type soldering iron. soldering consumables. etc. Thanks. Arthur Hi all. Sorry if my original request was too vague. Lots of you assumed I was after a ready made product but thats far from the case. To avoid any more confusion Im ordering this, https://www.rapidonline.com/mfa-917d...mbled--37-1215 to get me started. This has a 3mm shaft so you might help me locate the fixings required to fix a mini saw blade that has a 6mm bore in it. Cant help you but Im intrigued by your project. Is this a working model that youre building rather than a device just to saw tiny pieces of wood? Tim -- Please don't feed the trolls |

I will build a chassis from acrylics and/or wood. You may need to make the top of it very thin to allow a 30mm OD blade to poke though. This has a 3mm shaft so you might help me locate the fixings required to fix a mini saw blade that has a 6mm bore in it. That might be something you will have to make. Cheers, T i m |

Thats all brilliant, the mini table saw has all of the components I'd expected to see but the table saw is not what I'm aiming for. I am familiar with taps and dies from my days as an app' a long time ago. |

The ready made one previously listed says approx 8000 rpm (no load) dropping to 5000 rpm for a 58mm (2 inch) blade. You originally indicated that you were going to use a 30mm diameter blade so for the same cutting speed at the edge of the blade you would have needed approx 16,000 rpm (no load) dropping to 10,000 rpm, hence the comment that maybe 3500 rpm was too slow. I also note that the motors used in the commercially available products and those shown in the DIY Youtube videos take 60W to 80W under load while your selected motor is rated closer to a maximum of 3W. Your get-out maybe is that you are not trying to cut 9mm plywood etc. However I would recommend that you rig up your chosen motor with blade and power supply and see what it can cut before committing to an enclosures. You may discover that you need a bigger battery and your unit morphs from a micro table saw into something larger. Remember also that a child feeding in a piece of wood though a slot is not necessarily going to keep it consistently square to the blade and could easily stall the motor. For comparison a Dremel type tool can be 80W+ and with their (smaller) cutting blades on plastic they recommend around 10,000 rpm and closer to 25,000 rpm for soft woods. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |
