Hello,
So I'm insulating my house myself with 2 part spray polyurethane foam
insulation. I like to overfill the stud cavity slightly and then trim
the foam back flush with the studs. Using a hand saw works but is
fairly laborious and creates a "snow" of fine foam particles.
What I'd like is a 16" wide straight hot wire cutter on a yoke, then I
could run the two sides of the yoke along two adjacent studs and have
the hot wire cut the foam in the stud space flush. Is such a device
commercially available? Obviously I could make one but would prefer
a quicker solution.
Thanks, Wayne

damn hard one, no one sells this thing, everyone tells you how to make
one, but most of them are smaller than the one they used at my brother
in laws last year (that one was about 2 feet across)

No, those are all hot wire cutters set up with a table, sort of a
bandsaw for foam, you take the foam to the cutter. I need a portable
device I can use to cut the foam overflow in place, flush with the
face of the studs.
I did eventually find one on ebay, item number 5981682489. Now I just
have to figure out if I can get one locally.
Cheers, Wayne

If you don't want to drop a lotta cash, it's easy to make one.
I used wire from an old toaster, old power supply(I only need about 24v to
get it hot enough) and a "bow"
My bow is a 2x2, 3 feet long, on each end there's a rod sticking out
perpendicular about a foot.. the wire is attached to those.
Eezy peezy :)
