it's Friday fool and you need this tool
welcome back to another glorious episode of it's Friday fool you need this tool my
name is Kyle Voss and every Friday I bring you a tool a
tool that I use here in this shop or that I have featured on this channel
sorry that I've been mi a the last week that family in town and so turn on
vacation I guess this week's tool is a very cool tool cool tool it's a cool
tool that's in heaven for this week's tool is the shrinker stretcher
I mean a shrinker stretcher does exactly what the name implies so it will
basically take metal si metal and shrink it or stretch it depending on what
you're trying to do shrink it or stretch it so for instance if you had a piece
like this like this piece originally was flat it just had some small sides on it
and then what I did is I came in here and shrunk all this and shrunk this side
which caused the part to actually bend actually cause it to curve because
you're shrinking this edge and you're shrinking this edge here now you can
actually make this thing curved the opposite way if you were to stretch it
so if I were to stretch these little pieces here it would have curved the
other way or I could make a deal like an S shape like I could have shrunk it here
and then started stretching it there and it would have curved this way and then
rolled like that so just in that simple part you can see all the things that can
be done or made with this piece just simple shrink or stretch it the shrinker
stretches I'm going to show you today is what they call a deep throat shrinker
stretcher and it allows you to get more than just just these small little pieces
in there to do the shrinking or the stretching
so for instance you can put large panels like this in there now this panel this
the curve to this panel here was 100% completely done with a shrinker
no no mallet no bead bag no English wheels just the shrinker and
the deep throat shrinker lets you get into this panel a little bit to shrink
some of this stuff on the inside so basically i did was i started shrinking
the edge then i'd shrink on the inside a little bit and then shrink the edge some
more then maybe hit a couple of spots on the inside then shrink the edge and as
the panel begins to shrink it begins to curve it it kind of gives you this
curves panel now you can see where all the teeth marks are from the dies you
come back in here with a plan assure take a lot of that out if you wanted to
but you can it just gives you an example of what can be done with a shrinker
stretchered a deep throat shrinker stretcher very simply you can make some
pretty complex curves if you're wondering what these are I did a video a
while back a Friday video on some Dippold eyes that I've got that actually
punch and flare the diet the holes will see that link it up so basically the way
they did Schenker stretcher works is it has two sets of dies the top set is a
two piece on the bottom stead of the two piece died magnet clamps the metal it
either brings it together or it pulls it apart depending on whether you're trying
to shrink or stretch so like a shrink er it's going to grab it then it's going to
push it grab it push it push it push it and it's really pretty simple it's not
rocket science but it's very effective they work very well and make short work
out of stuff like this so let's go over to the shrinker stretcher that i've got
show you it so you show you kind of how it works show you that alright so this
is my deep throat shrinker structure by eastwood
basically that what makes the deep throated that has this cavity here there
are some smaller ones that don't have this cavity basically to stop for here
and you can only get what like an inch worth of material in there this
particular one is on a foot-operated stand you can also get these with a
handle on both the non deep throat and the deep throat come with handles and I
also have a kit offered for foot activation
I like the foot activation a little better you can kind of use two hands and
then use the foot to actually shrink or stretch the metal you do have to be
careful because you have less sensitivity on the foot action deal and
you can split it if you're trying to stretch it too much or sometimes you can
over shrink then you here are the dies so you can see these just basically
unbolt the die exactly come out and then on this particularly unit you have a
separate set of dies one-fifty shrink one fit to stretch actually you can see
the guys in here got two dies on the bottom there's two
dies on the top and as I activate this thing you'll kind of see the upper dies
come down will contact the lower dies and when they do is squeeze them
together
yeah that works now that squeezy motion is what shrinks
the metal there's another set of dies over here you can just basically replace
the ones that are in there the other set of dies does just the opposite so that
comes together it spreads it apart which stretches the metal pretty simple so
like I said it just got a piece of metal goes in there just like this and
strength if you're going to see this thing bin you can flip it over you kind
of work this thing around and really
really create some type tight radiuses
alright guys there you go the shrinker stretcher this one here is the deep
throat trigger stretcher by Eastwood there's all kinds out there from the two
couple hundred dollar range up to the couple thousand dollar range I'll be
sure to drop some links in the description of a variety of those you
can go check them out determine if it's something you think
you might want give you sheet metal and stuff it's a great two and a half shirt
you will see me using this thing a lot more here in the shop as I begin to take
on the bib stir build a lot of those custom panels will require some
shrinking or stretching I should be back next week like regular like regular
schedule vacations over more fabrication in the shop more videos
for you guys as always thank you for joining me I will see you guys next week
it's Friday fool
