Excuse me if this has been covered (I've searched & not come up with exact matches...).
I have been cutting my Acoustisorb with an angle grinder, which scares the crap out of me.
Any safer alternatives to cutting it?
Ta,
Bob.

Re: Cutting Acoustisorb
A sharpened machete can be a good tool for cutting insulation and should work well for acousticsorb. Just swap one dangerous tool for another.

Re: Cutting Acoustisorb
go and buy a electric carving knife from kmart
hopefully by the time its blunt , your done
after many years using an 18 century millers pair of scissors which are razor sharp and great but hard work
i watched a guy with a electronic carving knife .. i fell to my knees and cried
now last week of coarse i was looking at my large industrial bandsaw sideways and thought ...i wonder
...bingo
band saw is the ultimate way to do it ... but we dont all have band saw do we ?
i believe there is a circular saw blade now made for the job as well - check with tontine
but angle grinder ..? deary me

Re: Cutting Acoustisorb
go to china town / your nearest asian grocer and buy a Kiwi brand meat knife (pics http://importfood.com/thai_knives.html ).
Get a good blade sharpener.
I have a couple of these things as they're great cheap kitchen tools and can be honed to a razor sharp edge + they cut through Tontine acousticsorb 3 like butter.

Re: Cutting Acoustisorb
I did loads of it with a (sharp) Stanley Knife and a straight edge on the floor - one pass through halfway - and the second pass gets through. Fast and easy - and an accurate cut

Hi Ian.
I tried shears - methinks I would not make a good country bloke....

Yeah +1 on that recommendation Chris.
Important part is a new blade in the Stanley knife.
If you're cutting the really thick stuff then you might be better to get a professional box cutter knife.
Put weight on the straight edge so you compress the Acoustisorb... makes it easier to cut but make sure you keep your fingers out of the way.
Another option is to make yourself a hot wire cutter... works like a hot knife thru butter.

An angle grinder?... that's sort of like using a chain saw to slice bread!

well, i tried everything I had around me....it was such a mother to cut.
So, I went (oh oh oh ...Tim Allen noise) Angle Grinder!!! 8)
The first cut, I melted the acoustisorb.....the second it wrapped around the shaft...
By the time I was finished I was a dab hand...very very tired....and me and the room were covered in shit. 8)
The traps came out well, and the room sounds good, so I guess it was worth it....still though, if I had a bucketload of cash, those real traps ones look easy to work with...8)...and probably require very little angle grinding...8)
