all right today what we're going to do is sew sew a patch panel here get this
mg fender here with a guy wants to repair and you can see it's a lot of
legwork and from the back side we saw a lot of holes back here so we gotta cut
this out a couple different ways that we can do what we're going to do is
probably gonna come across
maybe blend down or come into here you can see we've got a compound is a
90-degree another 90 degree coming back here and a 90-degree fendt been with
them just like maybe five six spot welds
so what you need to do this you guys pretty much have already made welder
safety your glasses gloves always when working with sheet metal 4-inch grinder
and pick up some of our flaps these things are great both for a well prep
you'll see how this will remove any of this surface rust in a moment and then
well blending real nice they run pretty cool so you not workin metal pencil or a
scribe
I like using pencils one sheet metal instead of sharpie sometimes using a
sharpie on there
you don't get wiped off clean you go ahead to start building your privates
and it starts bleeding throw a tape measure tape itself a square now cut
metal to the choices you can hand job with some snips here or to make this
nice electric shear which I'll use that just to show you how cuts it's great you
can do scroll cutting general radiuses straight line but the heart of it is our
patch panel kit and this is the kit opened up here
this is great just pretty much gives you all the necessary other than answer
layer here to get the job done
our new 16 seeming pliers these things are great these are equivalent to a
small break self drilling screws here
these are used when you want to do any type of patches in the floor
you go ahead Julia patch panel drill some holes around here
forward to what you want and run your sheet metal screws in there pulls up the
old floor onto the new metal being
go ahead and do your perimeter well pull out the screws and just do plug welds
double-ended 316 drill bits here with these are used for us for doing a plug
weld holds and we'll show you that
so let's go ahead and get started first thing you see I got this up on our
fender stand and if you just do a little bit of body work and sand on the fender
it's fine you can lay it over but if you're ever going to do any like we're
going to do a lot of work
here's a little trick right there just tack it to the stamp you come across
your cutoff wheel
zip it off what it does is a lot more sturdier than chasing this thing all
over the horse itself so last part
the metal itself what this is this is our aluminized steel
this is the same aluminized material that a lot of the large exhaust
manufacturers are using for corrosion resistance and that's what we offer that
way when you go ahead and put the patch panel in here
your backside we're going to tell you go ahead and private but you got the peace
of mind that you're not going to have any corrosion starting to get a bunch of
these 1 inch wide strips
I'll show you some tricks here these are going to be used for our call backers to
go ahead and get your patch panels coming couple 12 x 12 and 12 x 24
so you can see and do some large patches with this
cut it out you can do a lot of small holes one of these kits will get you
pretty much ha
depending on the severity of the corrosion you have on the vehicle it
could do everything that you have on now for a fraction of the price of a
replacement panel so we're going to go ahead and get started here we're going
to do is find an area
what we're going to do here either come across or that market
go ahead and flap discs and on this side here we'll get the corrosion off in here
start drilling out the spot welds
yeah
all right we got the spot wells drilled out you can see we're down there two
metals really weeks what we're gonna do it our patch manager to come around
their reports that area
you can come in here now just slowly pull the metal top piece here right off
your base structure
got a ground down here on this side where the spot welds we're coming across
here when things you want to do
never have this sharp 90-degree corner here just take a file break that corner
just never end up with a sharp corner on any kind of sheet metal work
trustee manila folder can't go wrong with your just gonna get quick rough
size we know we need about a three quarter inch overhang there
we're going to need a 90 on the bottom so the easiest quickest way to get lines
on this is just take your drill
you get a real good idea of your rough opening see we're gonna come around come
down here capture this same overhang but then right here what we do is just
brought it out go the area where missing metal here catch that corner up and it
comes across hills and then under here
same thing we're going to keep this 90-degree flange running all the way
back
so what you can see is this is what you're trying to do a Butt well here
attacking Matt on there and as long as your template your patterns cut exactly
the dimension to your opening
that'll work out but if for any reason you have to do adjustment we end up with
a gap you have a problem here either cut a new model or you're trying to fill in
what you don't want to do is try bridging that gap with your MIG well
because of it
you know the weld deposit is going to be more brittle and surrounding here that's
where you're gonna get your cracks
you'll see the hairline in now your primer levels
alright so what we'll do to eliminate any of the fitment here going to use
doublers and that's what these strips are for their included with the kit and
this can be done for a small you know eight and a half inch patch like we're
doing here for the full run of a quarter panel
the process is done the same what we're going to do is we're going to cut these
two lengths they're going to fit behind here at the doubler you see they're
about an inch why
so we're going to do is put half inch up here we're going to drill some 316 plug
weld holds
now we clamp it plug weld it now that's your doubler you're backing plate
so now when your patch panels in there if you have any little miss fits right
in there were just alignment doesn't work out
go ahead and now you're welding to the dr back up late and to the main
peace here great for strength and also just to take up like I said any of the
little issues
now with this being aluminized on here we're not gonna have to worry about any
type of corrosion in the seam never what we will do is I will spray it with some
of our well through primers just two out
just give a little bit more insurance same thing with the back of this panel
first what we want to do though
pick a size it's close to your template here and and unfold your template
mark your bends
again all we're doing is following in our folder template
go ahead use your seeming pliers
things are great my six inch lengths covers a lot of your panel just get on
your bed line
a nice flat surface
you just get you 90 degree breakdown and what I'm going to do is run been just a
quarter of it up since this is longer
slowly work it that way you have a very uniform then we'll do is we'll just keep
working that up do this Bend fold it over a couple minutes and i'll have a
patch just going to drill a couple holes here recreate the spot welds just do
this with three 16-bit little trick with sheet metal
he was going to end up with that burr on there rotary deburring tool is the best
thing you don't have it
just a quick one is drill bit up three sizes up from what you're using to clean
it up real nice behind here we're going to plug weld down so i want to do is
more same thing about an inch apart and when you're drilling these another trick
if you can hold your ground trying to like this and ran through the edge of
that you can end up pushing and warp and give yourself a backer block
yeah
go ahead and cut your backer
I think thing like sharp corners that easier to weld angle corner
let's say from the skin you can clamp this
you got any type of vice grips well the clamps whatever you want to do you show
your prototype fear of our new spot well plier guys great
all right now we just got done with top ones here you see they look almost like
factory spot welds but actually plug welds want to do is same thing
take our backer
and think think we're just gonna we want up the lights will get more TechEd in
these are easy to grind their flat this takes them right off
what it does is now it gives you here's a but well where you want to be right up
in there now we cut this
we got pretty lucky gonna cut it worked out pretty good but if you're a little
offer you got to fit you now can weld to your backer
well your original metal to the backer and then fill it go ahead and blend it
and you've got a nice sort of concave well which is perfect to begin if you do
need a skim coat if you wanna just come up with your filler surfacers we just
line up our patch
it's going to work out real nice down here you can see that it's still going
to clamp right in place right there
come up along this side just going to go ahead and just a corner here
really well in here
spots come across here to attack so we're going to do is going to just start
working work here a little here
keep moving around filling it in what we're going to do is she had just two
quick stitch well we're going to do is just to burst
just hold it for you know just a moment less than a second
- 45 together they move to another area and come back
that's it
now what you do you come move somewhere else
get a couple more in and keep moving around
now you see what just a couple minutes of grinding just a few quick hits with
it with a 60 grit flap is how quickly levels that bead right off of there now
be able to come back
smooth it was a real nice interesting panel back side here
well prime where we can leave it as is we see where we have solid portman here
with the welds through there and then they patch panel piece into our backer
tied into the original piece of steel
