Step 3: Step 2: Strip the frame

I used a combination of paint stripper and sandblasting to get the paint off my frame. Alternatively, if you do not have access to a sandblaster, you can take it to an car paint shop and get it sandblasted and painted. 

Make sure to get all the paint and any rust off the frame. If you decide to sandblast yourself, it can be a laborious process, but you can do it! 

*Important: Wear a respirator while sandblasting to prevent silicosis, which is caused any tiny particles (in this case, sand) that get lodged in alveoli. Silicosis is a chronic disease and is no fun. Thanks to "retasker" for reminding me.
<p>Those rims are pimpin'!</p>
Track nuts might be a good upgrade. (they have attached washers that allow the nuts to rotate and apply much more torque without wearing down the cups or knurling on the washer as it grips the dropout. )
For my recumbent, i went to a 7 speed sacks hub. <br>So, the chain issue is the same as for a single speed. <br>The drop outs are verticle, so what to do? <br> <br>Bike nashbar sells a chain de slacker / tensioner for single speeds. <br>Its kinda like a derailleur with a spring arm and 1 pulley. <br>Ive been using it for years now. <br>So far, its performed very well. <br>I highly recommend it. <br>
I posted an instructable on fixing vertical-dropout bikes as single speeds (wouldn't recommend doing it to fixed-wheel bikes though, but coaster/drum brakes are ok with it). I made a chain tensioner before from a used road bike derailler (cut off the cage and run a through-bolt through the top pulley. It worked fine. Good to hear the Nashbar one holds up.
Thanks for sharing, could you attach the link to that product?
Hmph, Looks like nashbar doesnt carry it any more, but <br>google is our friend, and <br>it came up with this: <br>Looks like the one that <br>i bought from nashbar years ago. <br> <br>Chain Guide - Idler - Tension - Single speed - NuVinci ... <br>Staton-Inc a world class manufacturer of motorized bicycles, bike engine kits, gear drive kits since 1984. <br> <br>http://www.staton-inc.com/store/products/Chain_Guide_Tension_Single_speed_NuVinci-540-38.html <br> <br>For lotsa possibilities, check out: <br> <br>https://www.google.com/search?source=ig&amp;hl=en&amp;rlz=&amp;q=single+speed+chain+tensioner&amp;oq=single+speed+chain+tensioner&amp;gs_l=igoogle.3... <br>
Very cool thanks for sharing
Chain tensioners ('single pulley derailers') are also used on a lot of folding bikes. You can try and get those. I know thaht they're sold seperately.....
I don't know, I think it looks cool.
Thanks rickster.
how much did you end up spending?
I ended up spending about $300. I got some parts as gifts for my B-day, and x-mas. The bulk of the cost was the wheels ($100), paint job ($100) and frame ($40). The parts in total are probably worth around $400-$500. Purefixcycles.com sells fixies/single speeds for only $325, which is a great deal. But the parts are not as nice, and they don't have old frames like the one I used. And you don't get the satisfaction of building it yourself. But they are a good company. I bought some parts from them.
I agree the saddle looks far too low. It might be the right size for your legs, but on this style of frame, the handlebars shouldn't be higher than the saddle, especially with drop bars. I think you'll find this very uncomfortable to ride for any extended period of time. Also, I think the handlebar angle needs adjusting, they look too level, a good place to start is with the ends pointing towards the rear brakes, so your wrists aren't bent and your forearms are at a 90 degree angle. <br> <br>I suggest these pages for further reading: <br> <br>http://www.jimlangley.net/crank/bikefit.html <br>http://www.peterwhitecycles.com/fitting.htm <br>
I think you have some good suggestions, and I'm actually going to try raising the saddle after reading some articles by Sheldon. However, I also think we as humans like to over analyze things, and find patterns where they are non-existent. It is actually very comfortable to ride, and did my first 40mi charity ride on it along with my friend who has a regular road bike. We did decent, and beat alot of people with $1000 plus rides.
Nice build, but please raise that saddle or get a smaller frame... This just looks awfull and must a pain to ride :S <br> <br>I know, you need to get used to the crouched position on a bike, but trust me, it's way more relaxed to ride that way. <br> <br>PS: Never noticed this: &quot;We have a &quot;be nice&quot; comment policy.

depends on how tall he is, I'm short,and on my roadie I have to have the seat slammed in order to ride it....and it's a relatively small frame....and i'm 5'6'' I need liek a 46cm top tube and a 63cm seat tube for my size
And that is 63cm center of BB to the top of the seat tube? That sure is big for someone who's (5'6&quot; =) 167 cm! :O <br> <br>I'm 175cm and ride a 57cm daily roadster (Sparta Pickup) and a 59,5cm Koga Miyata road bike (which would be more pleasing to ride in a 57cm size...)... :P <br> <br>Still. The looks get totally destroide when riding a roadbike with the saddle rammed in all the way down. There has to be drop between the saddle and steer ;)
yea, it's jut a cheap biek to begin with anyways...only paid $20 for the whole bike...I&quot;ll get something better eventually....my Mountain bike is a 15'' frame and fits me jsut perfect with about 9'' of seat tube showing.....(It's an XC/AM bike)
You did say &quot;please&quot; so I think you might be okay. :D Oh one way to diffuse a lot of tone issues with your communication style is to use smiley faces. It worked for me when I worked at Target HQ and got in trouble for making people cry(not intentionally).
HAha, thanks for the tip!
What's her name? I suggest Anna Banana. : ) <br>LOVE your bike!
Hmm you know I actually haven't named it, or decided a gender..I'm open to suggestions! Anna Banana...perhaps. I was thinking of something that instills a little more fear..
I'm sure sandblasting is best, but why not just sand the shine off and repaint? Cars are not sandblasted.
Well in this specific case the paint job it came with was really shoddy. Paint was chipping off just with some fingernail pressure, so I decided to sandblast the sucker.
If you use real &quot;sand&quot; to do your sandblasting be sure to wear a respirator or risk silicosis (caused by inhaling dust from the sand). <br> <br>Use commercial sandblasting material which is more expensive but safer.
Yes, good point! I did, and I shall add that in the step. Thanks for the feedback
Awesome! I love fixies!!! you definitely have my vote! <br>-BLUEBLOBS2
This is the most complicated and difficult portion of the work. It would have been nice to see a walkthrough, or at least some tips. Guidance would definitely be helpful for selecting and installing an appropriate hub, spacing the cogs properly (if you're going from 2 or 3 down to 1), getting the chain tension right, etc. Could you add a little more here for those of us who aren't super-well-versed in the details of assembly?
Sorry about that, yes I will try to add more details. Alot of the info I got from Sheldon's site, and I'll try to find the links. thanks for the feedback
It appears as if you are missing the top nut from your headset. This nut is very important because it keeps the headset from loosening, a loose headset can cause knocking when applying the front brake as well as make the bearings wear faster. I'm not sure if it has since been remedied, but it would be worth procuring the nut if you haven't already. <br> <br>Good instructable, and enjoy the bike!
Indeed I am, you sniper you. It didn't come with one so I've been having to adjust it every now and then...very annoying, so I'm looking for one currently..
Hey, man <br> <br>Toward the end of the video you seemed to have lost the legs of your pants!! <br> <br>(Great 'ible!)
Ah nice, I was wondering if anyone would catch that....yes it got a little warm as time went on. haha
Very Cool. You are going to love it. But be sure to throw those straps on! Also, what bars are those? They don't appear to be normal track drops, they are crazy intense and I love it.
Thanks man. Oh yeah I rode it once without straps and haven't done that since...its absolutely necessary to get up steep hills. The bars are made by purefix (purefixcycles.com), and I like them. They are a little different.
Cool Bike. Nice job.
thanks !
Beautiful! <br>
