what size holesaws for autometer gauges? - Third Generation F-Body Message Boards

I was looking for 3 3/8" and 2 1/16" holesaws to make the cutouts for my custom panel. I can't find that size anywhere. Are the holes supposed to be those sizes?

Google? You're going to pay close to $10 for each size not including the arbor.

Yes, they're supposed to be THAT size.

well on the 2 1/6 i hae always went with a 2". the little movement it makes will get the hole real darn close. then i would use a file to finish. i was always able to get the gauges in real snug that way and 99" of the time they were tight enough not to need the brackets.

Thanks, i ordered them from amazon. I'm just stumped as to why i can't get those sizes from walking in to a hardware store or home depot or even sears.

Check Autometers website. They will give you all the installation information that you need including hole sizes and much more.
It's best to get it right from the horses mouth so to speak.
Good luck.

Just FYI... If you use a 2-1/16" hole saw, you will amost definatly need to use the bracket. If you want them to be interference fit, like they are also designed to accomodate, you want to go with the 2", and slowly take off more with a file as one92rs mentioned.

If you are using the brackets though...you'll be ok either way. Ive never been able to find a 2-1/16" hole saw on the shelf at a store. Always ticked me off haha.

I would always use the bracket regardless. It supports the gauge and will help it survive all the different amplitude vibrations present.

IMO the easiest way for 2-1/16 gauges is to use a 2" hole saw and then use on of those round flapper wheels in a high speed drill or pneumatic angle drill and dress the freshly cut hole, that way there are no burrs and the gauges fit tightly. That's how I did these:

Eh... Those gauges are built well enough to withstand quite a bit of abuse. Otherwise they wouldnt make gauge pods since you cant use the bracket with those. Some of mine use the bracket, some use the interference fit...no issues with either on my TA or on my Jeep. Two extremes. One sees lots of vibes, the other sees huge impacts, dirt, and water. Im an Autometer fan I wont lie.

Actually...I would think being loose would help resist vibes. When its tightened up with the bracket, more vibes can transfer to the internals vs. the gauge maybe shifting a bit. But I dont think its really an issue.
