Considering that I have an old bike, I always try to research about ways as to how to prolong its life. One time when I was cleaning the bike I discovered that there was this grease nipple on the axle part of the swing-arm. I tried researching about it and found out its use. That didn't stop me there, I also found out that this can also be applied to the head tube.
I then tried it on my bike and here is how I did it! We only need the following:
handtaps 6mm
Here are the steps.
First I located a part on the head tube that I can access easily. I then drilled a hole using the smallest drill bit that I have. Then I used the 5mm drill bit in preparation for the hand tap.
Then I used the hand taps. If you notice the 3 hand taps that I have doesn't have the same threads. Since we want to somehow make the nipple self locking as possible we will use the hand tap that doesn't have a uniform threads. I hope you understand what I mean.
When using the taps, make sure that you lubricate when drilling. And of course we turn it clockwise. Take note that in-order to achieve a nice thread, as much as possible align the taps 90' i reference to the point of entry. Its a good idea too to use some sort of lubrication when thread ie. WD40 or the old trusy singer oil.
Now after threading has completed then we slowly take the tap out by turning it the opposite direction. Then we install the grease nipple.
After which, I then headed to the nearest gas station to get some grease pumped into the grease nipple.
2-3 pumps will do. Just check until grease would come-out from the top and bottom part of your bikes head tube.
Project Cost:
Grease - 10php x 3 pumps
