DIY carbon frame repair

Wheels of Happiness

One need not worry about repairing carbon frame.  No need to bring to rush this to CNC near Sta Lucia for 4 to 6 figure repair.  You can do this yourself.

Steps:

1.   Do the coin test;   Tap the part you suspect to be broken.  If the sound changes and sound becomes dull, then it is broken.

2.  Remove other parts.   Cover the other parts of the bike, paper, masking tape to prevent epoxy from spoiling other parts of the bike.  Use safety equipment:   face mask, gloves, if needed respirator.   Carbon fiber dusts are bad for the skin and lungs.   

3.  Sand paper the broken part.

4.  Cut the carbon to fit into the broken part.

5.  Mix the epoxy.  Some say 1:1  (hardener to epoxy) some say 1 to 2.

6.  Apply epoxy with a brush (tooth or paint) to the broken part and the carbon fiber.

7.  Paste.  Apply more epoxy.  To be sure, you make this three layers.

8.  Attach compression  tape.    Secure with electrical or duct tape.

9.  Shrink the shrink tape with heat gun or hair dryer.

Training to be DIY mechanic trains your mind to be meticulous and detailed

This post has maintained that sports and business are similar in approach   you have to train,  you  have observe a process, you have to have a goal, you have to prepare your inputs, study your processes to improve your ride and strength.   You have to watch what you eat and many more.

Same with business.  Above you all, you have to be passionate.

Same with being DIY mechanic.  As I disassembled the Campy crank, I have to observe very well the sequence of removal (to aid me in reassembly)  observe what is abnormal with normal.  I observed the bearing and the axle to be grimy and filled with grit.  There were gaskets that are probably interfering with the rotation of the crank

I had to be meticulous and observant.  Same as in business.  If it is failing, I have to know what are the factors that cause it to fail.  

I know I have continue doing this, ie being vigilant of what can go wrong, Otherwise, I I  will wreck the bike

Being a biker trains you to really do a lot of repairs yourself

Being a biker trains you to be a Mr. Handyman.  Kasi if you have everything that goes wrong with your bike to be done by the mechanic, you are in for a lot of abala and expenses.  Sometimes all you need is patience, focus, pair of pliers, allen wrench (hex) and a little understanding of mechanics of the bike.

Today:   I fixed the following on my bike:

1.  Tightened the cables for the front and rear derailleur of the Sava MTB and the Bianchi road bike
2.  Removed the grating sound of the rear derailleur of the Bianchi (a little 1/4 turn of the low screw of the RD)
3.  Adjusted the cables of the Sava MTB so that it can shift to the biggest rear sprocket (34)
4.  Put loctite on the crank tensioner bolt so that it wont fall off again (as it has several times)

I also washed the bikes and removed the grime from the chain ring and the sprocket.

In the house I was the handyman, the DIY guy:

1.  I replaced the LED bulb outside the house on the western side;
2.  Replaced the bulb of the lighting fixture inside the house
