Watch this space! Next post will be a reformatting of Aaron Chan's Home PC. We will also discuss changing of a master slave disk drive to a master primary! Coming soon to the DOME near you! :)

My first catch of this site is to fix a shower head that had degraded due to rough useage and ware and tear... After careful consideration, I decided to recreate a catch for the shower head...

NAME OF PROJECT: Shower Head Catch Replacement
PROJECT DESCRIPTION: My parents need a quick repalcement for the shower head catch since it had broken apart. They just needed a fast solution to this problm and did not require high perfect.
DATE STARTED: 9TH APRIL 2005
DATE COMPLETE: 9TH APRIL 2005
NUMBER OF PROTOTYPES CREATED: 1
CLOCK IN: 1:00AM
CLOCK OUT: 3:11AM
COMPLETION STATUS: COMPLETE

Wheres the wear? Haha... you see the tear? :P

Haha... this is what it looks like when done :)

**It is recommended that you skim through the whole solution first before attempting to follow the steps. If not you may find yourself lost due to my incompetent english... Haha... Engineering student lar... what to do? :P **

Heres how to fix the problem:

STEP 1: Obtain a square aluminium rod. The dimesions across corners should comply with the diameter of your shower head. Aluminium is the obvious choice here because we dont want it to rust, and the properties of aluminium give us that advantage over corrosion.

STEP 2: Do a dimensional sketch of your shower head catch and hence calculate the length you need for a sturdy construction. Then, use a set-square(haha... I know my looks rusty but its still working :P) and a carpenter's pencil or workshop ink, or pen or whatever... to score or draw a line for ease of following during machining later.

Mark wih set square and pen/pencil

STEP 3: Being machining your metal rod by first sawing at the score mark then follow the lines you have drawn initially...

Saw with appropraite metal saw

Square result

STEP 4: Now you have to cut a slice off th square rod to allow entry for the shower head. Check the diameter of your shower head and mark the lins accordingly. Then score and saw. Haha.

Sliced workpiece

STEP 5: Right now, we are going to use the sliced metal piece as a backplate later. So, use a pair of pliers and a hammer to bend it to a curved shap. The curvature should not be too much. Just slightly will do.

Complete contour - not too bent.

STEP 6: Now we need to drill holes for nuts and bolts! I decided to use imperial scaled metal drills. Namely the 5/64". Haha, of course it depends on the nuts you want to use later.

select drill size

Fit to work tool - Im fortunate to have a hand tool, but a large drill would work too :)

STEP 7: Mark two points for drilling along the centreline of the sliced plate. Remember, you have to leave some space in the center. This will be seen later.

DRILL!

STEP 8: This is a crucial step. Mark the hole on the back of te siced square piece(haha, not square anymore is it? ) This is so that you can drill the main module later... The piecture starting to form in yr head now?

Clamp and drill

STEP 9: Here is where I leave it to you. For me, when I was working on this last night at around 3am ( or should I say morning? ) My mind couldnt think of anything else better so I settled for this. Its a pipe collar and I found a few sizes in my dad's spare parts cabinet, so I decided to make junk into gold...

STEP 10: Select appropriate snuts and bolts for fastening the pieces of metal together... (almost there!)

Screw into rod

Maintainence Complete!

There! Thats it! Remember, this was intended as a temporary solution to the problem and that this is just a prototype. In my second design which was never made into existance, there was solder to reinforce the sides to reduce stress at points of stress, and rubber for more firm gripping.

**PLEASE REMEMBER TO FILE THE EDGES SO THAT THEY DONT CUT YOU!**

Well then, thats that. If anyine has anything else to fix, just drop me a message or something ya? Hahaha...
