Hi, it's Ray Shalene from Pro Shaper Sheet Metal in Charlton, Massachusetts
0:13
And tonight I'd like to talk a little bit about the difference between area and arrangement area and arrangement
0:20
are the same as What's commonly called form and shape? And it's I thought form and shape was really confusing so I
0:32
Introduced the terms area and arrangement. You know, let me define what area and arrangement means
0:39
Area would be the surface area of the panel you start out with a black a blank of
0:48
Metal that's basically flat and if you measure that surface area it has so many square inches and
0:55
And then through a process of shrinking or stretching or a combination of shrinking or stretching
1:02
You change that area value. Well, let's just say that the area value was
1:09
222 square inches when it was a flat blank and When you finish up with the panel, you will have more than
1:19
222 square inches if you have a shape like this But the value that the number of square inches will be different from what it started because you've introduced shrinking and stretching into the
1:32
process So the terms form and shape Area and arrangement are describing the same thing. Let me to describe what it is
1:42
So area I call all of this surface here now that is what
1:49
The term shape is also described as and shape is interpreted as
1:55
The way it looks it's sort of like a universal word for the way something looks
2:01
But I found out that if you go in the dictionary and you look up shape
2:05
It says form and if you look up the word form it says shape. So that's not really helping things
2:11
so then I did study a bunch of jewelry how-to books and
2:17
They use the term form exactly the way some of the metal shapers were using the term shape
2:23
So again, that's another point of confusion. So that's why I added when I started teaching my classes
2:29
Area and arrangement I think are more descriptive. So this is a
2:35
area value I call and It has a certain amount of area that's been
2:43
introduced into the panel through the metal shaping techniques and it also has an arrangement value
2:50
So there are two distinct values and when you're making a panel the area value is paramount
2:57
It the primary value you have to create the right amount of area in a panel To make that panel what you want it to be if you want it to be a Motorcycle fender a motorcycle gas tank or whatever it has to have the correct area value
3:14
Which can be determined by a buck or a flexible shape patent or just by I
3:20
So this is an area value. It's also an arrangement value So we see what it is. This was made by one of my students in a so 40 thousandths thick aluminum
3:32
shape And it's a wheel pant for a racing aircraft one of my students from Georgia
3:41
He made this a couple years ago. He had a racing plane He wanted he had fiberglass wheel pants and he wanted to make some aluminum wheel pants
3:49
So he never done he had never shaped sheet metal before and he made a wire form and
3:56
Made this panel up. This was his first one and it's a pretty good job But if you decide you want to make a couple more and the way you would make the wheel pan is make two of these and then weld them together
4:05
And then it gets cut out for the way the wheel goes and say aerodynamic fairing for the for the wheel
4:12
landing gear wheels so This is got the area value and arrangement value right now for a wheel pan a half of a
4:24
racing aircraft wheel pan and and If I do a modification here by going like this
4:33
I'm taking the arrangement out And I'm putting it into what I call the curl arrangement now this curl arrangement gives you a
4:45
Really big advantage when you're making the panel now you can see that that has a a
4:52
Low crown now to it and you can do it on both ends
4:56
You can do half of the panel at a time and now the crown is much lower as opposed to now
5:03
We'll pop it back into arrangement Because it has that area value which I call the DNA of the panel already there
5:12
It'll want to go into that wheel pant arrangement So if you could do this literally
5:20
millions of times It'll just keep going like that So you can you can twist it
5:28
like this And you can actually By doing that it's not even recognizable as a wheel pan
5:38
It's the start of a pretty good little sculpture, but it's not a wheel pan. So if you want to go back into the wheel pan arrangement
5:46
you're just Persuade it a little bit And it goes right back into that wheel pant arrangement
5:56
So this is a major component of shaping metal is being able to take the
6:04
Panel out of arrangement that allows you to use a low crown wheel in a long Stroke rather than going sideways you could work this this way here but it more efficient to go this way So here another example here
6:20
There's a little motorcycle fender that was done as an exercise by Davey Johnson from New Zealand
6:27
He was here about probably a year ago or so And he just wanted to make a small motorcycle fender and he wanted to use a harbour freight wheel and
6:36
And we did do some tipping wheel tricks on it We put this nice little peek in with the the tipping wheel and then we put a little joggle here on the edge
6:46
And we welded in a doubler over here It's a lot easier to weld them in then then to try to tip it all the way over
6:54
So it's a pretty attractive little wheel and he also a fender and he also did a little reverse curve on the on the back
7:01
There's some flaws in it, but he was it was just doing it as exercise
7:05
So let me show you how that starts out. Alright, so here's Davey Johnson's little motorcycle fender and
7:14
This is what it looks like when it starts out. I believe this was like 36 inches long and
7:21
Eight inches wide or I believe the blank was and using one of my shrinking facilitators
7:28
he hammered it the Gathers spontaneously pop up on the sides you knock them down a little bit of stretching in the middle and
7:38
That's all the shrinking and stretching you needed and you end up with this is basically like a loop
7:43
This and this the exact same thing so After you get it out of the shrinking facilitator with all the malleting that you took on and that only takes 10-15 minutes
7:54
Then you need to wheel it out Well, this is one of the Haber Freight English wheels with one of my
8:00
Kits on it that puts it from a bottom adjuster to a top adjuster and I think this will be
8:07
Self-explanatory why I really like the top adjusters versus the bottom adjusters
8:13
If I had the setup as a bottom adjuster There would be the the screw would be down here and it'd be no clearance so I can put this panel
8:23
Of course this has been planished out already, but that's how it was planished out right here
8:28
So as you can see that that would be impossible to do so you can put this in this hop afraid English wheel
8:35
with my kid on it And you can planish this out to a glass smooth finish
8:45
And I find these hop afraid wheels are actually a really good entry point for anybody that's interested
8:50
Interested in learning how to shape metal. It's a very low expenditure
8:56
You can always upgrade later to a better wheel But this is a really good wheel if you're just doing restoration you want to make
9:04
Small patch panels or even if you're doing just motorcycle work. This will do just about any type of motorcycle fender or motor
9:12
motorcycle tank and It works really well It surprising how well it works It a narrow wheel and that a disadvantage But in these smaller parts it not an issue
9:27
So this can get all wheeled out planished out nice You get all the whole field ends the middle and everything try to get it all nice and even and
9:46
Then after you get it all planished out, it's nice and round like this then you basically have to open it up like this
9:54
you're changing the arrangement to the working arrangement to The arrangement that's desired now I should have a blanket on here. So but I will do it without the blanket so
10:07
to get these sides to come over you got a They're a little reluctant but that number metal is clay
10:16
Same thing. So what I do on this is I'll take a leather slapper
10:22
Wood slapper and coax these down and as those go down the diameter opens up until you get the desired
10:31
diameter and this side pieces were put in a shrinker after we got it over quite a bit and then just hit the sides with a
10:41
Shrinker I hope that explains the difference between the terms area and arrangement
10:46
Like I said, that's a great tool to be able to change that arrangement
10:51
It allows you to use a low crown tool across the board whether it's power hammer planishing hammer
10:58
Auto body dolly English wheel it doesn't matter you can change the arrangement you get a smoother finish
11:05
Finish because you can use a larger contact area larger contact area means
11:11
Smoother finish if you have a high crown die You're going to have wheel marks and all kinds of die marks and everything
11:18
so We'll be talking a lot more about this was hoping to get
11:23
The first video done on the e-type aluminum nose that we're making the v-type bonnet
11:29
Which is going to be made with flexible shape patterns and today mark my cameraman
11:35
He's also my flexible shape batten guy this is the really pristine 62
11:42
Jaguar e-type nose section and we marked it off to the different
11:47
panels that are we made and It's all got the first layer of the low stick tape on there and I sell this tape in my in my website also and
12:00
What we're going to do with this now is we're going to mark this all up with
12:03
With index marks and gauge locations and you'll see that next week
12:09
We'll have a video really explaining how the flexible shape patent system works
12:14
