MAKING THE DRUM



I am not very good at mechanical part of things..,but i tried my best.

for making the drums and the structure or frame.,it used some materials

(not the best materials i kno;)but i used them coz they are easy to work with

and are very cheap and lightweight.



As shown in the diagram.,the drum has 3 layers.Most of the drum is filled with

Thermocol or foam.i used thermocol(better rigidity).I googed the

drum sizes for a standard drum set.and cut 4 circles with these diameters

on a large slab of thermocol.The drum sizes are listed below.Cut the

rexin and boncy materials with the same diameters, as shown in the diagram.

Now at the center of the thermocol cut a cylindrical grove such that the

tail portion of the T junction fits tightly in the hole.Now mark 4 positions

on the Thermocol nearby the portion of the t junction.(keep in mind that this is

only for extra strengrth.the drums wudnt fall off even if the drummer drums it

hard.).



Now that you got an idea on were the t juction would be on the drum,

remove the junction.Now using the sandpaper.,sand the sides of the thermocol

.This is to getrid of any deformations that you may have while cutting.

Make a grove on the thermocoal along the axis.(axis is the imaginary line

on which the pvc pipe would lie on.)



Now apply fevicol (SH grade) on the walls of the grove on the thermocoal

and on the T junction.Do not use SR Grade coz it will melt the thermocol.

(fevicol is the name of the manufacturer in india for glue.ill put

up the picture also. u can use wat ever u have at your country.)And use a piece

of string to tie the T junction and thermocol.,loop the string throung

the groves that we jus cut on the thermocol.now tie it hard tie on the T juncton.Apply the

SR fevicol on the string were it touches the PVC T junction.(bevare not to

tounch SR on the thermocol.)The SR would cause the PVC to melt parcialy

and the thermocol gets fixed on the t junction.



Now take a piezo disk and solder it with 2strand ribbon wire.(strip 2 from a 10 strand ribbon wire)

make sure to insulate the both leads with insulation tape.now solder the other

end of the wires to a female port 3.5mm audio jack.use a smal plastic piece to screw

the jack in.Make sure that the length of the wire is equal to the radious

of the drum.(we dont want any extra wire sticking out of the drum.)



Using the SR glue.,glue the piezo disk on to the center of the

boncy material that we cut out earlier.Use insulation tape to stick the wire a

and the disk on to the circle.Now glue the side containing the piezo disk

onto the thermocol.Make sure that the 3.5jack is properly placed.and can be

pluged in from out side the drum.(Use only SH for sticking with thermocol.)

Now use the SR glue to stick the rexin on to the boncy material.Leave for drying.





Now for painting the drum.I used spray paint(paint-in-a-can).The

problem is that you cannot use this paint dirctly on thermocol.since

it causes the same effect as the SR glue.it melts the whole thing.

So make a coating of duct-tape on top of it before spraying it on.

I also made a coating of news paper and then a coat of duct tape.

(not necessary.)

Apply a coat of paint.Hold the can a good 25 cm from the drum and

spray it contantly moving,to get a good fine finish.or else.,it could be uneven.

Leave to dry.Repeat after 5 min.





This step covers making of the drums.but making the cymbals and the pedals

will be explained in another step.The problem is that i couldnt photograph

the making of the cymbals and foot pedals.I don have them with me at the

moment either.but ill take their photo as soon as i can and upload them too.

Il up load the steps for now.







Tips :# When ever you use a solvent(like fevicol SH or SR)u havnt

worked with before.,always test it on a sample before

applying it on the original.

(i am emphasising this cos i wasted 1 of ma drums by using

SR on thermocol.The whole thing melted into guie slimy slury :( )



# When u fix the jack (fixing the piezo) make sure that the jack would

be on the easily plugable area of the drum.(u don want it to be on the

left or right part of the drum.coz it may be difficuly wen another drum comes

on its side.)



# Always measure and mark the parameters on the drum by using sum permannt

marker.



# We would be cutting the matterial for all the 4 drums together.

so its easy to mark them which drum they belong to.and their axis.



# Always check how it would be on the frame before gluing on anything.





note:- standard drum size as per a website i googled up.

18 x 22 inch bass drum

9 x 12 and 10 x 13 inch rack toms

16 x 16 inch floor tom

5.5 x 14 inch snare drum
