Place your drum head on a hard surface...concrete is great like a garage floor or basement floor. Put the center of the Circle Cutter where you want the center of the hole. Press down the stopper and turn the blade. It will cut through the mylar like a hot knife through butter. Voila! Bass drum port!
Thanks for the reference, but that's not what I'm talking about. When it comes to drum ports, KickPorts, and other porting methods, we are literally flying blind as to the exact port size (and depth, if appropriate) that will result in maximum output at the desired frequencies. There are so many variables involved in actually tuning a bass drum via a port (drum diameter, depth, head(s) resonant frequencies, shell resonant frequencies, port placement) that this might be an unsolvable problem without a very complicated, all-inclusive formula.

I have destroyed 3 reso heads in the last 9 years trying to cut a hole. One was the hot can, then an exacto knife and most recently, the Bass O's cutting tool. I'm done. I am bad at it . Now, I just buy a pre-cut head with the reinforcement ring on it.
Yes, it will help a lot. That's one of the only reasons I put a small 4" hole in it. I don't bury my beater, but I was still getting flutter. Heck, you can even hear Tony Williams' pedal flutter if you listen closely.Just curious, I have never used a reso head with a hole in it, does it change the feel much? Only reason i'm asking is i bury the beater and lately for some reason i can't stop the bounce.. was wondering if a hole would help with that since it would let air out and possibly not move the batter head so much?

Cool.. and thanks. didn't wanna trash a $50 head for no reason And the sound of flutter doesn't bother me, it acutally throws me off on fast doubles and is annoying. I usually can tune it away but lately i just can't seem to get things right.
Cutting a hole will dramatically help with bounce/flutter. I port all of my bass drums for this reason. Many say that porting kills the tone of the drum but I personally have never had a problem with that. If you feel like your bass drum is lacking tone after porting simply tune your reso up a half to a whole turn on each lug. I can lay into my bass drum for punch or feather it for a deep boom. I use a clear emad batter and coated eq3 reso with 4" port on a 16" bass drum... Most would say that is a recipe for a dead, lifeless, quiet drum but for me it's quite the opposite: loud, deep, resonant, and versatile.
Nice.. going to order a cutter and see how it goes... right now i'm using a 22" with a SK1 and a Un-ported regulator.. it sounds fine, just the flutter. Should i bother with a kickport or just cut it and be done?
Plus it will be nice to be able to change muffling without removing the entire head
so.. top tip for anyone that will cut a hole in a head... i used the gibralter $10 tool and it works amazingly well.. tested on a snare head first and perfect hole..
Now the fun.. my reso was a regulator which has a ring in the middle and the tool hit it, so i had a tiny bit that didn't cut.. DO NOT just grab the cut piece and give it a light tug.. RIPPPPPPP..... and $50 gone
on the upside.. zero flutter.. i have been playing for almost 6 years with no port and always had flutter... i should have tried this earlier Now i need to figure which head to order...
