hi everyone so today's topic is if you

want to fabricate a flange with five or

10 or 20 holes on its PCD then what do

you do and how to do why I selected this

or figure or figure means like five

seven nine these are some odd figures

because this type of transits are little

difficult than two four six eight or

twelve sixteen twenty for this type of

holes are quite easy than five seven

nine holes before going to the subject I

will show you some examples to do two

four six eight twelve sixteen or twenty

four holes on France PCT so let us do

this so what I did here is randomly draw

one circle and draw a straight line with

the center point

this is for the tools you can draw two

words through your PCD the second one I

will draw four volts

first I will draw a line through the

center point and divert this center line

forwards by following the same method

you can draw eight numbers student

number walls or 32 Romberg words now you

will draw another bowl another circle

sorry a circle and if you want to get

six number holes on pc d then the same

ladies we have to draw over the pc deep

and you can get six number of votes

by dividing the same six points you can

get six x to 12 and multiply by 224 the

same method you can get 2 4 8 16 and 32

and same matter by multiplying 6 holes

you can get a 6 12 24 or 48 volts so

going back to the subject suppose we

want to make a flange with PCD X and

have 5 volts on PCD how to do so first

method is Dave's equation by following

def situation you can get the x-value

now you have to draw the BCD or your

plate draw the PCD it's a center part

and you know the quarter length and the

quarter length over your BCD like this

put a first point over your PCD now draw

the quarter length value non value and

draw water easily now you can get five

points let us do the second method a

little draw the circle which is our

record BCD and draw a straight line a

and B with reference of center point

oh okay draw the circle another one

circle

Hoppa which is half of your P series by

keeping pointer on your divider at the

point B and we have a intersection point

a marked here as point M and now draw a

straight line from M - o and extend up

to the circle and draw a straight line

from M to be an extended up to you

circle - okay and you got two

intersection points R and P okay I named

it and draw a straight line from point P

to O and extended up to circle one first

circle you will get an interest a second

point five okay next

keep your divider at 0.5 and point M

draw a circle three third circle which

is third circle by keeping your divider

point at point B now you will get an

intersection point X and straight line

M oh and are now draw an arc

draw an arc on circle one on your first

circle by keeping a divider point at

point five and other point at point x

the same arc you have to draw on circle

1 which is your first circle and draw

another four segments now you have 5

points 1 2 3 & 4 & 5 let us go to the

third method so the third master is

quite different it is I let it draw the

circle and draw the straight line to the

center point now divide the straight

line a and B and get another straight

line C and D

name the center part oh now what we have

to do is divide the straight line

oh and B divide the straight line oh and

B get a point intersection point M here

you got an intersection point we named

it M keep your divider pointer at em and

draw circle to this second circle you

will get two points X and our sorry X

and while I named x and y now draw the

third circle which is half of your PCD

dimension the what I mention the radius

value by keeping your divider pointer at

why

you will get two intersection points one

and three the third point is to now draw

the fourth circle the fourth circle from

the point X and we will get another two

points four and five the method is

called as Carlisle's circle method

mentioning the circle one two one one

two three and four four egss here are

the points one two three four and five

let's go to the fourth method draw the

straight line to the center point and

now what you have to do is divide the

straight line a and B now draw a

straight line through your intersection

parts

which is C and D in the center part is

zero sorry okay now divide the straight

line o and B and get an intersection

point I will named it m now keepo /

enter at m and draw a circle with a

reference point B or o to draw a circle

your midpoint M and reference point o

either be nope

now what you have to do is draw a

straight line C or D 2m d 2m you will

get an intersection point P now draw an

arc by keeping your divider pointer at B

and D with reference point P and get two

intersection points one and two these

are the R of your Pentagon now the same

arc value have to draw over your PCD

circle you can get one two three and

four and five points let us go to the

fifth method draw the facility circle

draw a straight line through your Center

Point named it as Y a and B divided the

straight line a and B you will get two

intersection points C and D

b c and d in the center part is okay now

divide oh and we get an intersection

point I named it as a M keep your

divider pointer at M and draw an arc

with the reference point C now you will

get a point P on a big line draw an arc

by keeping a divider pointer at Point C

with reference point P will get a point

one on your circle you got the first

side of her Pentagon now draw these arcs

over P CD and get another arcs and

points one two three four and five these

are the filter from these five methods

the second method on the third method is

space consuming time canoeing and also

looking complicated but the force method

under fit method is what easy then the

second and third method so better prefer

to go with fourth and fifth method I

prefer to go with fifth method hope you
