    This morning I did a couple of tricks so I could get all treats.
    I did a little modification to the wheels, they where made for presta valve stems, which I hate. So I had to drill out the valve stem holes for a standard Schrader valve.
    Valve stems measure 21/64
    20181031_065548.jpg
    The holes in the rims where 1/4"
    20181031_065716.jpg
    These are double wall alloy rims.
    20181031_065737.jpg
    I drilled one bit at a time from 1/4 up to the 21/64 so I was only taking a little material at a time. I didn't want to get a catch and take the chance of distorting the hole or the rim. Here you can see the double wall and the bur around the freshly drilled hole.
    20181031_072123.jpg But I happen to have a brand new set of chamfering bits.
    20181031_072149.jpg I just turned the chamfer tool with my fingers to remove the bur. Soft alloy and a new cutter was easy and quick.
    20181031_072554.jpg
    I installed a new rim strip.
    20181031_072812.jpg And a new gumwall tire and tube. The wheels are now ready.

    I took the fork to the chrome plater the other day for an estimate to get it nickel plated, price was the same for nickel or chrome, $200 :scare3: I said I could buy a new part all ready chrome plated for $50. So off to plan B.
    I used a flap sander and sanded off all the flaking and pitted chrome and smoothed out the transition. I was able to save about 2 or 3 inches of chrome on the tips of the fork. I then masked it and shot 4 coats of what else, rustoleum gloss black, there wasn't anything wrong with the fork other than the chrome. Pics later when the paint is dry.

    So while the paint is drying and I'm at work I decided to work on the pedal crank arms and sprockets, again nothing wrong with them, they just need a good cleaning.
    Some before picks.

    20181105_170840.jpg 20181105_170847.jpg 20181105_170853.jpg
    I left the old pedals in the arms while glass bead blasting to protect the threads, really didn't need to though as the process is pretty gentle on the aluminum. Gotta clean the sprockets next with a scotch brite pad, they are chrome so no glass bead for them.

    I've been rubbing on the sprockets with a scotch brite pad, they are not chrome, plated with something but a dull rough finish. So of to the glass bead treatment they will go.

    Before.

    I think I saved the fork, paint came out nice and it still has some satin chrome on the tips. I'll do something with some decals or pinstriping or both.

    20181106_134757.jpg still has some chrome on the tips.
    20181106_134803.jpg this is where the bearing race goes, I kept the paint off of this press fit area.
    20181106_134811.jpg I also kept the paint off of the threads, they will get greased upon re assembly.

    I get absolutely zero shop time right now because of work and trying to get things done on my home. Tinkering on bikes like this let's me work with my hands which is a very important basic need for me. I stripped it while I was exercising in between sets, I clean parts at work in between part cycles, so at least I am getting something. And I'll assemble it the same way. Still waiting on the frame to come back from powdercoat, but that has given me time to clean parts.

    I can do some of it, the parts I run take 4 minutes for each cycle. And I'm usually the only one in the building, the boss doesn't care as long as I'm getting my numbers.

    Reflector brackets before and after glass bead blasting.

    And I cleaned the chainring screws.
    A little rust but not to bad.
    20181106_181548.jpg a scotch rite pad did the trick, I dont think I'm going to worry about the socket rust, you'll never see it when it's on the bike because they are so small.
    20181106_181601.jpg as far as I'm concerned these are done.

    Probably, but it's not that big a deal. I already bolted everything back together and you dont even notice the rust in the sockets. Maybe I'll give em a wipe with a q tip and some wd40.

    Worked on cleaning up the brakes today. These are old school dia-compe center pulls, very good brakes back in the day.
    What I started with, a dirty brake assembly, I took it apart and cleaned everything and rubbed it down with a maroon scotch rite pad.
    20181115_100923.jpg And it came out like this.
    20181115_112120.jpg 1 clean and 1 dirty.
    20181115_112720.jpg both clean and ready to go back on the bike. They'll get new brake pads of course.

    Todays work was cleaning up the shifters and front brake cable stop.

    This is the fork lock nut and front brake hanger before cleaning. Pretty rusty
    20181117_102556.jpg And after cleaning.
    20181117_110024.jpg The shifter mount was real rusty, especially on the bottom, just needed a good cleaning in general.
    20181117_110140.jpg These are old school friction shifters, the wing nut adjust the tension on them.
    20181117_110155.jpg All disassembled for ckeaning.
    20181117_110615.jpg
    I prepped the shifter levers for glass bead blasting.
    20181117_130327.jpg After blasting they have a nice satin finish and the inner friction surface is still smooth and intact.
    20181117_130424.jpg All done.
    20181117_130856.jpg It came out nice.
    20181117_130904.jpg
    A little trick I do on the rusty chrome is to spray the parts down with wd40 and let it soak for 20 minutes or so, then I spray a piece of scotch brite down with wd40 and have at it, works well and saves the chrome...........sometimes.
    Worked this time.

    I picked up the frame today from the powdercoater. I have some work to do on it before I can start putting parts back on. They got powdercoat in the threads for the bottom brackets, i have to get that out, and I have some black painting details I want to do.

    It looks awesome in the sun.
