  • Cutting Holes

    I am building a custom dashboard for my M37/Cummins 4x4. I need to cut 8 holes 2.06" and 1 hole 3.750". I have Plasma and a circle cutter but worry just a twitch and I have a big Oooops. There is no one I can locate in Northern NY that has CNC Lazer or Water Jet. Any suggestions how you would cut the holes. The Material is 16ga cold rolled sheet.

    Thanks
    Paul

    yes, use a whole saw, 2" and 3 3/4", use a dremel or file for the extra 50 thou

      be carefull with hole saws. they often cut the hole a bit larger than the bit says it will. example = 1" cutter, 1. 105" hole

        Just curious, what are you doing on the dash board that requires that kind of precision. Most instruments fit rather loose and the bezzle covers the cut.
        Maybe a picture of what youre working on. Sounds interesting.

          my post should read: get two good quality hole saws, one at 2" and one at 3 and 3/4" BTW, what kind of gauges are you using that need holes down to the .001? Every gauge I have ever done has had clamps and a bevel ring that will hide imperfections up to 3/16" of an inch just fine.

              I see we had the same thought. I was thinking that the bezzle peice might be what he is making. You could also scribe the cut with a compas and use a hole saw 1/8" or more smaller and then grind out to the scribe lines. 16 guage material can even be brought down pretty quick with a 1/4 round fowl.

                    I want to see that Cummings on your table. Really the Greenlee punches
                    would cut aluminum that thick but it would be a bit much for MS.

                      The gages are Auto Meter. VDO also lists the same sizes.
                      the 2 1/16 gage shows a body size of 2.06" and the Trim Ring 2.28"
                      The 3 3/8" gage body is 3.34" and the trim ring 3.81" Sorry for the typo in the first post, NOT 3.750" but shoud read 3.34" Looks like a good quality hole saw. I do have some Greenlee Punches, but not in the sizes I need.

                          Looks like a great project, I'm envious to the max. Looks like you have a good grip on enjoying life.

                            Well if that was a 325-hp, or better yet the motor home class Cummins engine you had. And you would be willing to abort the idea of installing it in that old Dodge, and drop it in my 2004 F-550 I would give you this machine, with the Hypertherm 1250 plasma, computer, and water tank
