So I do some wood working as a hobby, and I have an order to make a cigar humidor. I am a novice when it comes to cigars, so could use some advice. I am wanting to mount a hygrometer to the front of the humidor, but I can't find any info on how this should be done. I can't even find a picture of the inside of a humidor that has a front mount. It seems like the hygrometers are wider at the front, so I am assuming I would drill a smaller hole, and once its pushed in it will be flush. Does their need to be some sort of seal or gasket to make the hygrometer air tight? Also, how far into the box does the hygrometer need to be. My humidor is going to be over a little over an inch thick. Most hygrometers I have found are .7" thick. Any info you guys could give me would be greatly appreciated.
