| Post subject: | Pencil Grinders Reviews Wanted |
I'm looking for reviews for pencil grinders. These are the ones that interest me the most as they fall into a afforable price range and are priced according to speed it seems. But others are welcomed. Forget the HF as I got bad reviews on the quality of it and don't want to hassel with it. Sioux 5979A, 70,000 rpm, The one in Keith Mackenzie's Pantograph/ Dupicator. I think this is the one to compare the others too. http://www.amazon.com/Sioux-5979A-Pneum ... B0001X1YLA Sioux 5978A, 60,000 rpm http://www.amazon.com/Sioux-5978A-Pneum ... B0001X1XOS Astro 218, 56,000 rpm http://www.sjdiscounttools.com/ast218.html This is what I have but I'm not sure if I want to use it for my dupicator. I think I would rather have a dedicated grinder for it and leave this for it's other intended purpose. http://www.scmsysteminc.com/engraving.php |

I sounds like you are about to make the pantagraph from your video. I also think it is a useful project. The grinder that John Hall sells would seem to be good. Fred |

I think Kieth's was a Souix. Jim was saying that that is what he would use after having trouble gettign the Harbor Freight ones to work. |

Fred my IBEW brother, Do you know if that's the Astro? I'm leaning towards the higher rpm as , yes I'm gearing up for the duplicator, because it will be cutting shell and I believe the faster the better in this case. The one thing about the grinder is they use 1/8" bits as opposed to my hand piece using the smaller dental bits so getting bit sizes might be easier. Although I might be able to hit my Dentist up next check up.

John, You are correct Sir! You must have posted while I was editing my first post. And Jim did tell about the HF grinders and that's why I have no interest in them as he gave me his thoughts on them. |

Chris, If you already have a dremel you can use that. That is what I use on my duplicarver that I posted in your other thread. You'll just have to add a parrallelogram mechanisim or other to remain perpendicular to the table...see pics in your other post. The dremel with a 1/32" carbide bit does a nice job on shell, as long as you don't go too fast. Chuck |

That's just it Chuck. The dremel is too slow for cutting shell really. And the duplicator is for small scale precise jobs. The pencil grinders are lighter and I understand that the Dremel changed their design a few years back and have runout issues where the pencil die grinders don't if you have a good one. The dremel is also ttoo heavy for this type of machine. You duplicator is a large scale dupicator made for duplicating tops ,neck and etc. I may later build a larger one for making neck but this is primarily for just doing inlay and small carvings and precision work at a relatively low cost. So far I have $42 wrapped up in Drawer Slides, Hinges and screws and $15 in T slot track and knobs and bolts. So I'm figuring at least another $20 -$30 more for parts minus the hand piece. Funny how that stuff starts to add up quick. |

I use the souix 70000 rpm. I buy them in bulk. You won't go wrong with that one. The design is to cut metal so you know you have a good tool. They will do inlay work like a dream |
