Cutting Cushion Foam using Electric Kitchen Knife

Sharing buttons:

this video is brought to you by sailrite

in this video we'll be cutting dry fast

or open cell foam with the Accu cutter

and also a standard electric kitchen

knife we'll start with the a key cutter

350 the base of the a key cutter 350 is

flat so you can run it along a tabletop

to create a straight cut and it does a

great job cutting this foam now let's

use the electric kitchen knife we're

gonna mark the foam here so we can use

it as a guide to help guide our blade

then we're also gonna line up the foam

against the edge of a table so that our

blade can run along that edge this will

keep the blade nice and straight will

realign the foam here before we cut so

that that line is directly on top of the

edge of the table you can pick up an

electric kitchen knife like this at any

good department store I think you'll

notice the results here is just as good

as the active cutter 350 the only issue

with the a key cut of 350 is that it

cost quite a bit of money whereas a

standard electric kitchen knife only

costs about 15 dollars or less we can

also use electric kitchen knife to make

angled cuts we're going to mark our foam

here at 2 inches and draw a straight

line on the top so we can use that as a

guide for the top of the knife so we're

gonna angle this foam that you would

want to angle the foam if you had a V

birth and the foam was against the hall

of the boat then we're gonna put a glove

on and we're gonna hold that knife being

careful not to get cut and have a second

person guide the knife at the bottom

edge of the foam if you must be careful

when holding the blades at the top with

your glove do not want to hold in front


the blade where the teeth can cut into

your glove and also into your finger so

be careful you do that and then as long

as you have a person watching the bottom

portion of the blade and a person

watching the top portion of the blade

you can get a perfectly cut angled piece

of foam

all right let's get a close-up of this

and let's also get a side angle view to

see how the cut came out so using an

electric kitchen knife works great as

you can see you can also use the

electric kitchen knife to cut wedges out

of the foam to create a curve in the

foam here we're cutting a wedge out of

the dry fast foam and you'll notice when

the wedge is removed that the foam

creates a nice curve if we're satisfied

with the curve we'd then glue it in

place when cutting wedges out of foam

it's not uncommon to cut smaller wedges

until you're satisfied with the curve

with the foam creates so here we're

cutting out a little bit more foam to

make a little bit deeper wedge to create

a little bit sharper edge curve on the

phone in this next example we're gonna

cut a wedge out of a larger sheet of

foam here and you can do it exactly the

same way using that electric kitchen

knife we used a marker to mark the foam

for the position that we're gonna be

cutting this wedge because it's very

difficult to see your cut once you get

started we're gonna speed up the process

here but you basically just want to cut

until the wedge is removed it's always a

good idea to start with a smaller wedge

and then if you need the curve to be a

little bit more sharp kind of deeper




okay let's take a look at it

alright that's almost a ninety degree

curve we're gonna glue that section

together to show you how that's done the

sailrite recommends using a 3m super

trim spray adhesive to glue the wedges

together you can also use the Bostick

context cement that sailrite sells as

well we'll apply it to both sides of the

wedge once the foam is coated you need

to allow approximately a five minute dry

time before bonding the sides together

here we are five minutes later and we'll

use a heavy object just to secure the

foam in place until the bond takes hold

you can also wedge the foam between

furniture if you like if you've got a

big sheet this is eight hours later


here's what the curve looked like before

we glued the wedge together and here's

what it looks like after we glued the

wedge together it's approximately the

same curve about a ninety degree turn

because foam is expensive and sometimes

not the right size it's not uncommon to

glue sections of foam together to add to

its size we have a separate video

showing you different adhesives for the

dry fast foam be sure to watch that

video as well thanks for watching this
