Step 5: Fitting the suction pad
I moved from my shed at home into the University workshop for the next stage. Many may not have some of the tools or these kind of facilities available to them but you should be able to make do.
I cut out the disk into a perfect circle using the ban saw and a disk sander. I had made a paper template to see what size of disk i would need to still be able to fit in all my electronics. Next i had to fit the plunger to the bottom of the disk. I bought this plunger from B&Q for £3. It has a thread on the base which made it ideal. I drilled a whole large enough for the thread to fit through so i could screw on the plunger from the other side and it would sandwich the fiberglass disk. I then cut off the excess handle and gave it a quick sand for neatness.
