So it's like a parting tool, only 90 degrees different ?? I hate parting tools, except in brass. |

Do it all in one go. Screw a piece of fly or MDF onto your faceplate. Cut the steel out as squares, drill a hole in each corner and screw to the mdf of ply. Use a trepanning tool as shown, mine isn't as fancy it just a parting off tool with more side rake for clearance. Do the inner hole first, then move to the outer, don't worry about going all the way thru as you can pop the bit out and clean up with a file. If you do go all the way thru no matter it's only into a piece of sacrificial ply, in fact I have one face plat that has ply on it all the while for such jobs as this. Far quicker than hole saws, neater and they are concentric, 1.25mm thick is a doddle. John S. |
