8) Part 1
To make your own circiut boxes, from pvc pipes,allso capacitor holders ,even microwace cap holders etc etc. first you will need to make the corect size base for the size of your circiut. you will need a meter length of thin pvc pipe, do not use thick as it will need to much heat and will easily burn if you over heat it. or turn yellow.
Cut your pvc pipe to the length = to that of the project box you want to make. cut the pvc pipe down one side only then pry it open with your fingers,enougth so you can pry it open more when you heat it over a stove flame, of which will soften it enougth to bend open and out more.
Reheat it under different sections till mits soft then flatten it out by throwing it onto floor and standing on it once you have it flattend out as flatt as possible cut the rectangle size you want from it. that will be your box base.
Then with a few lengths of plastic corner moulding cut some peaces to make the base frame , then useing a mini high speed drill with small drill bit, drill holes through the held on frame sections and through the base ,then secure the frame peaces with small short screws, these will protrude inwards and will be caped off and concealed latter by the inner frame work .
Once you have secured the base section frame cut from plastic corner moulding, then cut 4 sections of plastic moulding to make the corner frame work , as you are biulding this circiut project box from base up.
Secure each corner leg frame with screws on each side of each corner, these screws will be removed latter to install the pvc panneling allso cut from heated and soften and flattened out pvc pipes , once you have done the corner frames then start on the top frame useing peaces of plastic corner moulding cut to length, and secure with small srews .
Once you have done this and cut and fitted the last top frame work section made of plastic corner moulding cut to shape you can then start on the panneling.
Using the same method you used to make the base part of the project circiut box, heat and flatten out the pvc pipe once youve cut it down one side. then drill it through the pannel and frame then secure with small screws if you remove one of the corner screws holding the framework together ,to screw on the pannel,you will still have a screw on the opiste side of the corner still keeping it in place till youve installed that panneling same applies to the top frame work .
If the panneling is a bit long dont worry you can file it down to the square easy after youve made the box. then once youve done and secured all the panneling, cut peaces of plastic corner moulding and cap the inside frame work to conceal the small srews use super glue to hold the inner frame work inplace , the final section is the lid made the same as the base youll need a fair bit of scres for the lid ,thats the only disadvantage of the lid as if you have to remove it to do a circiut repair youll have to remove all these screws to get the lid off.
But if you have an exsternal ic and tranny youll have an easy job to replace them as the ic will be on an ic socket mounted to an ic board of which protrudes out the front pannel through a small square hole filed into it. the ic socket pannel is held in place by 4 small screws with nuts . and the 2n3055 trany if your installing a high voltage output multi ignition coil driver unit you first secure a siutable size square heat sink to the rear outside of the pvc box with thin bolts .
Then secure the tranny to it with bolts that stick outwards and are secureing the tranny with nuts. so you can remove it easyer holes are drilled through the rear pannel under the heat sink for the tranny legs wires to go through , dont worry about collecter as one of the two heatsink bolts is collecter and inside the box where the collecter bolt is there you can put a tab strip with your collecter wire runing to if you are useing this pvc box for an ignition coil driver circiut .
The pvc box can be coated as many times as you like, inside to give it great hv insulation . steven [email protected]
This is a section of pvc pipe cut down one side for heating over a stove flame enougth to soften it and flatten it out , to cut out the pannels for the plastic corner moulding, made framework,
