Adding anti-spin bolts to bmx pegs

Another old article i wrote that i found..

This is a fairly easy project to do.

the bolts i used:
HILLMAN
M6-1.00 x 20
Socket Hd Cap Screw
Class 12.9

and the ones i found were black,and were metric. but you can use whatever you prefer.

here's the steps.

1.remove the peg and turn it upside down on a level surface.

2.place your axle nut on the peg and position it so it's lined up with the hole for the axle.

3.place your drill bit as close as your can to the edge of the axle nut. make sure the drill bit won't drill off any of the axle nut! ALSO make sure that the drill bit is just slightly smaller in diameter than the bolt your using!

4.drill slowly at first,applying just a little downward pressure. once you have a small hole started,drill at a faster speed and apply just a little more downward pressure.

5.as you get close to having drilled halfway through the sidewall of the peg,slow your drill speed a little and be very carefull because at this point there is the possibility that your drill bit will jam and the peg and/or drill will twist slightly out of control.

6.once you have drill all the way through the sidewall,take your anti-spin bolt and place it over the hole and hit it lightly with a hammer to get it in partially. once it's in enough to hold,carefully start hitting it hard as you can with the hammer. but make sure to hit it straight on the head,and don't hit your fingers!

7.by now the head of the bolt should be flush with the sidewall of your peg. congratulations,you now have anti-spin bolts.

NOTICE: this requires the use of power tools. using power tools can cause bodily injury,so ALWAYS wear the proper safety equipment. for this you should wear goggles,and thick work gloves. I DO NOT ACCEPT ANY RESPONSIBILITY FOR ANYONE GETTING INJURED! WEAR YOUR PROTECTIVE GLOVES AND EYEWEAR AND FOLLOW THE WORK DESCRIBED IN THIS ARTICLE AT YOUR OWN RISK! I ACCEPT NO RESPONSIBILITY IF YOU DAMAGE YOUR PEG! SO ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE RISK OF DAMAGING YOUR PEG!


now here is what it looked like after i added a anti-spin bolt to my rear peg:



Painting your bmx frame (Or any non carbon frame)

This was originally written over 5 years ago,but i happened to stumble upon the website that i had posted it on & figured it would be useful to some people.




Ok,for those of you who have frames that are all chipped up and you want to repaint them,this should help.

Step #1
Remove the old paint

To do this get a small paint stripped attachment for a drill. Put the paint stripper in just like you would with a regular drill bit and tighten the drill on it. Now before begining any of this,put on a set of goggles and a dust mask or respirator because the fumes/sanded paint can really mess you up.

Once you have your safety gear on,pull the drills trigger so the speed is about medium. Once the drill is going hold the body of the drill with your second hand while holding the frame down with one foot. Press lightly on the frame with the paint stripper attachment and move slowly and it will strip the paint off to reveal the bare metal underneath. Keep doing this slowly and carefully until you have as much paint off as possible.

Once you get done with that,you frame should look something like the photo below.



Step #2
Prime the frame

This is pretty simple. Take your can of primer and hold it about 5-6 inches away from the frame and move along at a slow steady pace while holding the spray button. Do not move too slow or you will get too much primer on and it will begin to run. This step is very important and determines how nice your actual paintjob will look when you get done.

Take your time when priming the frame and do several thin coats or so of primer until you have a nice layer of primer on the frame. Look over the frame and make sure that you cannot see any of the old paint or any bare metal through the primer. If you can see either,then go back over the frame with a couple light coats of primer until you can't see through it.

Once you have that done,let the primer dry for about 15-20 minutes if your painting in semi warm weather. wait about 30-45 if it's really cold outside. When finished priming the frame,it should look something like the photo below.


Step #3
Paint the frame

This step is the most important because it is the paint you will actually be able to see. Hold the can about 5-6 inches away from the frame and spray at a slow and steady pace,avoiding overspray. Basically just do the same thing you did for the primer. Make sure when done that the primer doesn't show through the paint. If it does,go over it with a couple more light coats of paint until the primer doesn't show through anymore.

Let the final coat dry for about 50-60 minutes in warm weather,and about 60-70 in cold weather. When done the frame should look something like in the photo below.


Step #4
Clearcoat the frame

The procedure for clearcoating the frame is almost the same as for priming and painting. With clearcoat move a little faster and wait about 5 minutes between coats to avoid getting too much clearcoat on at one time. Too much at one time will cause the clearcoat to turn white and it'll look almost like you spray white spraypaint on your frames new paint.

Do about 5 coats of clear. The clearcoat acts as a protective barrier to keep your actual paint from getting scratched. Instead of your frame scratching,the clearcoat will scratch. When clearcoat get's scratched,you won't see the scratches. However,if it scratches all the way through the clearcoat it will scratch into the actual paint and show up.

Long story short,more coats of clear is better than less. Now wait about 40 minutes or so depending upon the temperature before touching your frame and putting your parts back on it. If you touch it too son you will have fingerprints in your new paint.

The finished result should look like below.



Notice: I accept no responsibility for any mistakes or errors caused by attempting anything mentioned in this article. When painting or sanding always wear proper safety gear. This includes but is not limited to: Safety goggles,and a dust mask/respirator. I accept no responsibility for any injuries caused by ignoring the safety warning. Attempt the steps in this article at your own risk.

Bmx bottom bracket types: Explained

Article isn't written by me,but it does a good job of explaining the different types of bmx bottom brackets (I still say euro is the best though..)
