Cutting 703

I've got a couple 8'x4' panels of 703 that I'd like to cut into 2'x4' pieces - what's the best way to cut this stuff? (I will obviously be wearing a mask and goggles...)

I have:
Circular saw
Jig saw
Hand saw
Coping saw

Serrated bread knife. Works better than anything else I've tried. Use a tape measure, and let the metal tab on the tape score the 703 so that you know where to cut. Then free hand it. Easy as pie.

I used a sheet rock knife/razor.... easy and very little dust.

i was working with 703 at the time of the 9/11 - the al queda style knife is, i find,
of the best sort - go to your hardware store, tell them you're in hurry and
that you need box cutters, several.........

I use a very sharp “lineman’s knife” for cutting 703-705, after spending a long time with a serrated kitchen knife. (Less dust)

When cutting many panels:

Covering my wrists with baby powder before cutting seems to reduce the itch that will always find it’s way into latex gloves, tyvek suites, and other duct-tape mummy outfits I’ve tried. (Clogs a few pores in advance of glass fibers finding their way in.)

Also, rubbing your arms with a dry bar of soap immediately after the job can pull a few of the itchy glass fibers out of your skin before you have a chance to work them in with some well-deserved scratching.

Defininetly electric carving knife. I got one for about $20. also be sure to wear a mask so you don't breath any fibre glass in-it will never leave your lungs once it's in.

I second the LineMan's knife. One of my guy's uses it all day and swears by it. I think it works great too. Also, using a t-square and pushing down on the material (to flatten) can help you make a straighter cut. This is far less effective on the itchy 705......

I cut mine with a utility knife while surfing the web with a pocket pc researching the best way to cut it. Just cut and make sure you are well ventilated. A mask or bandanna might not be a bad idea. I swear a felt a bit bit itchy and short of breath after cutting about a dozen + sheets.

A circular saw will cut it very clean. Just adjust the blade to clear the material and away you go. I will look very nice.
