No-rez cutting tool
« on: 19 Apr 2022, 03:01 am »
Hey all,
I am going to be cutting no-rez with some miter cuts for the subwoofer enclosures.

I was planning to use a saw stop tablesaw when someone asked if the no-rez is at all conductive and would therefore trigger the saw stop brake. Does anyone know if it is conductive at all?

In general, are folks doing their no-rez cutting with table saws or miter saws or what?

Thanks all!

I cut no-rez with my Sawstop with no issues, but you can always bypass the blade brake if you're worried.

I make the main cuts, both straight and mitered, on the table saw. If I want to add bevels, I do that on the band saw after the pieces are cut on the table saw.

If you need to smaller pieces, and not use a power tool, these work great.  Got them at Home Depot.   They can cut through leather etc.

They are Wiss 10 in HD Tradesman Shop Shears. 

Model #CW10TM

Home Depot generally has them in stock.

I just use a bunch of cheap, single-edge razor blades.
They cut the foam like warm butter, then I'll fold it over to make it easier to cut the vinyl layer, then cut it the rest of the way through. Exacto knife works well for the vinyl layer and it wont dull nearly as quickly as the razor blades will.

I used an old bread knife to cut NoRes. It worked really well for me.

I used a band saw and was able to cut complex curves (for example behind the woofer in the NX Studio) with ease - after a little practice. 
And yes, it's good to have an extra sheet of NoRez to get that practice.

Bandsaw is amazing for it.

I use scissors however they might get a little gummed up.

I used a band saw.  Cuts like butter.  XLS Encore build.

Hey all,
Thanks for all the advice above.

For those who have done the bevel-cuts to made the no-rez inside the sub baffles, did you do exactly 45 degree cuts, or did you do a little less to let the pieces push on each other a little since they are compliant?

I havn't seen anyone recommend this but I figured out a really easy way to cut NoRez.  I use a big Exacto knife but use just the tip of the blade to score the hard side of the No-Rez.  You dont have to score it very deep. I then bend along the score line.  The No-Rez will split into two pieces perfectly along the line.  I then extend the blade and use the gap in the No-Rez as a guide to saw through the foam portion of the No-Rez.  This is really easy and fast and will create a clean straight cut.

This is exactly how I cut mine the first time. I've also used a retractable Olfa blade with better luck as that gets the super sharp cut for the backing but can be extended to cut the foam like butter in one swipe. No-Rez will dull blades pretty quick though, so whatever you use, keep some extra blades on hand.

I cut No-Rez on my Saw Stop very regularly with no problems and I do not disable the safety.

I used a carpet knife. It pretty much sucked, but got the job done. My cuts were not nice and clean like those pictured above, but I figured what the hell, nobody is going to ever see them, so I just carried on.

If you want nice clean cuts, do not use a carpet knife.

Sometimes the best advice is words of caution what not to do. :lol:

The SawStop is how I ended up doing this. It worked incredibly well. A miter saw would work really well too.

I was beyond anal because I have giant 6 stacks and wanted the very-visible no-rez to look perfect. I ended up making a couple basic jigs and doing it on a SawStop and got to about 1/16th inch precision pretty easily.

Thanks to all the folks who replied when I first started this thread.
