--- Quote from: drunkatuw on November 15, 2004, 01:50:47 pm ---Definitely don't try to use the trackball mounting plate as a guide for a flush bit on a router...I made the mistake and had to buy a second mounting plate. Even if the mounting plate is made out of metal, even an old router can rip right through it. I ended up using my old (read ruined) mounting plate as a guide to create a new template. --- End quote --- If the hole in the centre of the trackball plate is 3", I can just go ahead and create a MDF template with my 3" hole-saw right?. I can then fix this to the bottom of the plate (somehow) and use the extra depth for the flush trim bit bearing to ride against whilst cutting the hole in the lexan.... Is that hole EXACTLY 3" though....me measure when I get in from work! |

The way I see it, if the router bit is tight within the router and a steady-hand used, then there can be no movement up and down and therefore no chance for the router bit to 'dig in' and ruin the trackball plate. Does this approach look ok and is this the method used by some other people? As long as the bearing on your bit is right next to the cutting blades and you do not have any movement at all, then yess taht will work. However if there is any gap between the bearing and the cutting blades (which mine had), then you can't do that method. |

--- Quote ---Still can't find one of these polishing wheels. What are they made from Pix? is it a soft material. I've seen something called a ''flap whee', but this looks to have abrasive 'flaps' protruding from it. --- End quote --- Definitely NOT the abrasive flap wheel. Check here.. this is the type of wheel I used: http://www.hobbytool.com/index.asp?PageAction=VIEWPROD&ProdID=60 The 3" hole saw will leave a hole a bit larger than the hole in the mounting plate. |

Well I guess I'll have to use another method. I've just measure the trackball plate hole diameter and it's approx 3" and 2/8" (about 84mm). I'm gonna have to think of an alternative solution! |

3 2/8"?? Hmmm. Maybe I used a 4" hole saw. I'll have to check when I get home. |
