What tool do you metal pounders recommend for cutting circles? I welded up the side marker mounting holes and am read to weld in a disc in the large center hole -- don't want to pack that sucker with filler, ya know (IMG:style_emoticons/default/laugh.gif)
BTW, I have very shallow pockets so let's keep costs down (IMG:style_emoticons/default/welder.gif) |

Humm, without a pilot drill, you need to do it in a drill press.
Clamp it down (the sheet metal) on a block of wood VERY well or it will eat you alive. Or: Scribe the diameter out with a compass and cut with L or RH sheet metal shears. File or grind to clean up. Easy. |

What he said.... (IMG:style_emoticons/default/smile.gif)
or if you don't have a drill press put a block of wood under the metal and stand on it. Drill slow. Your shoes can as a guide for the bit. Wear old shoes. If you can't get a hole saw the right size, get one slightly bigger and grind the edge till it fits. |

If you drill a hole in a block of wood first (w/ hole saw AND pilot bit), you can clamp the block to the sheet metal, and drill using the hole saw w/out the pilot bit (or a drill press (IMG:style_emoticons/default/wink.gif) ).

If money is an issue, trade fancy tools for good old fashioned labor.
Just mark a circle with a compass (or a quater and the tip of a knife or whatever) and cut to the line with tinsnips. File to fit. Otherwise, use a fender washer - remove all plating - weld the center hole - and file the outside to fit the fender hole. |

Use two blocks of wood. Predrill a hole in one with the pilot bit, remove the pilot bit, sandwich the metal between the two blocks, clamp very tightly, and use the predrilled hole for a guide for the hole saw. Spend the money and get a good "BiMetal" bit. It'll last 100 times longer than the $3.00 ones. |

If you do the block of wood/old shoe method, make sure the block of wood is wide enough for your whole foot. I tried it on a 2x4. I lost my balance and fell backwards, obviously faster than I could get the bit out or stop the two handled 1/2 torquemaster beast drill, the metal piece slips out from under my shoe, gets flung off the drill across the garage, bounces off the car hood (not a 914) and imbeds itself into the far (finished) wall.
The wife hears the commotion, comes out and wants to know what the hell is going on and does everything I do lately have to include personal or property damage. "Maybe." |

Buy a set of green handled aviation snips... the offset kind. Cut to within a 1/8" of your line first, then do the fine trimming ...which is easier with less material to cut away, file to fit. The offset snips are great. I like the Wiss brand. You can twist them around a very small radius without leaving little daggers if you practice a bit.

I used blue masking tape from the front side.
I then cut the template out with an exacto knife. I then put the tape template on the sheetmetal. In my case, I called a friend with a plasma cutter. Otherwise, cut close with aviation snips and grind to fit. Good luck. |

The hole saw should've come to me cuz I have 3 different sizes staring at me on my peg board (IMG:style_emoticons/default/blink.gif) A pilot hole is no biggie because they are quite small AND I can weld that little hole closed quite easily (IMG:style_emoticons/default/blowtorch.gif) Jerry, tell the misses, "Yes, however cars prefer blood when they can get it." |

For saving time, use what ever you have handy to trace out and cut out a slightly over size disk and trim to fit on a grinder. You could have it on and tack welded in place in 1/4 the time it takes you to go find or buy the "right" tool and experiment. No matter how perfect the fit you make, your going to be grinding/filing down the extra metal from you welds.
