I don't know if anyone posted this before or not but I made a foam hole cutter last night that worked out perfectly.  I have been using an adhesive backed foam to seal the flash on my cameras latlely.  3/8" foam.  I took a piece of the steel sink drain (the drain trap- straight with an elbow)  that is 1.25" diameter, sharpened it on the belt sander all the way around.  locate the hole you want and push down and twist.  Cuts a perfectly round hole with nice sharp edges.  I cover the entire inside of the camera compartment door above the sensor with it,  covering all the glass and sealant.  Dosen't work any better but it really makes it look nice.  much quicker than using a knife or sisscors.   Any thin walled tube should work just as good.

Nice Idea, I have a heck of a time with scissors!

what's the size of that foam pad (besides the 3/8") and where'd you get it

Came in a sheet 24" wide by ???.  Got it from work and I'm not sure which vendor it came from.   I'll try to find out.

I use round pipe insulation and just cut it a 1/2" thick. it goes a long way at 98 cents for 6 foot length.  I think that was Welby's idea....can't remember who told me that.

I'll repeat this idea from Jaggermax for cutting smaller size holes in foam.
Take a piece of the appropriate size PVC tube and use it to press the foam down where you want the hole.  Sharpen one end of a piece of copper tube that fits nicely inside the PVC tube. Press the PVC tube down on the foam, slide in the sharpened copper tube in and push it down - perfect hole!

Thanks Jaggermax! Works great
