    A friend has some kind of gravity fed blaster that I will borrow tomorrow, so maybe tonight I will work on something else. Maybe the rear cowl, try that stencil...

    Awesome thread. Whatever else you can say about these bikes, it looks like they didn't skimp on the cooling fins. That 125cc mill looks huge!

    I have a long illustrious history of doing stupid things. As a child, it started with things like jumping off of the roof holding an umbrella to see if it would slow me down (it didn't), and jumping my mountain bike into immovable objects. I was more concerned with the jump itself than what was directly in the landing path. Once it was an apple tree, another time a closed garage door.

    Later, while living on Nantucket, the harbor froze, so I did what any wicked smaht brain-box kid would do: walk on it, with no adult supervision. Fell through. Cold, etc.

    I've fallen off of my house, towed more than one 5000lb vehicle with a 4 cylinder S10, been bitten by a rattle snake, driven a decrepit '84 Mitsubishi Starion LE Turbo to L.A. and back in one day, and last but not least, imported 3 Minsks into the U.S.

    I bring these things up because I think I have just raised the bar.

    A few days ago a friendly gentleman said I should try soda blasting my parts rather than using a wire wheel. It seemed like a reasonable idea to me, so I borrowed a blaster from my friend Deniz, went to Costco and bought 27lbs of baking soda, and went to work.

    I started the project outside, but after less than a minute of blasting I noticed the immense white cloud of dust going into my house, out into my driveway, and worse, over into my neighbors house. Being the polite gentleman that I am, I decided I should find an alternative to coating the entire neighborhood with a fine white powder.

    I remembered painting my old car trailer in my garage some time ago, and that worked fine. I stripped it all down to bare metal, resprayed it, and then when I was all done I just blew all the dust out with compressed air. No problem...

    Having put a good 9 seconds of thought into this decision, I dragged my air line back inside and went to work. Dust mask, safety glasses, hearing protection, compressor thumping away trying to keep up. Soda blasting is awesome. It strips off paint, rust, and that strange shmegma made up of 2-stroke oil and fossilized dust without hurting the aluminum, or even the seals.

    This concludes the cheery bit of my soda blasting odyssey.

    I was having so much fun soda blasting that I didn't really pay attention to what was happening to my garage until I ran out of baking soda. When I had a look around I realized that this was nothing like when I repainted my car trailer. Stripping the whole trailer probably created 60oz of dust, whereas I had just distributed 27 pounds of baking soda evenly across everything in my garage. Oh boy...

    [​IMG]

    Then when I went outside I realized that I had a pretty serious nose bleed; apparently a fair amount of baking soda was getting through my flimsy paper dust mask.

    After taking a good look around I decided that my garage was such a wreck that I might as well just go buy more baking soda (and a real respirator) and finish the project, it wouldn't get any harder to clean up.

    So the next day I finished the engine, then lightly blasted everything else. I used 40lbs of baking soda, on top of the 27lbs from the previous day.

    NOW the garage was ruined. It was more than an inch thick in places. Even though I had closed all the drawers in my tool boxes and closed the doors of the chemical cabinet, they were both full. It occurred to me that it would probably be easier to just move to a new house and forget this ever happened.

    On to the good part!

    Everything came out great. Here is the engine in primer

    While waiting for the engine to dry I made some brackets for the new foot pegs

    Two days in a row of working on the Minsk!

    Now I feel like I have made some real progress. Actually putting things together, starting to work on something that looks like a motorcycle, not just endlessly tinkering with loose parts.

    I did a lot today that I forgot to take pictures of... I have never done a build thread before so taking pictures of every detail still isn't second nature to me.
    The front fender was cracked, so I hammered it out and welded it up, then ground it all down and painted it. It's passable, but not great.

    Cleaned up the rear shocks and springs with some steel wool, made new carburetor gaskets and mounted the carb, and put on the kick starter and shifter. Then I remembered I should take pictures.

    I finally figured out where this black plastic fender piece goes
    <a href="http://picasaweb.google.com/lh/photo/VQMwnrFcxX2eFGnSjEtiqQ?feat=embedwebsite"><img src="http://lh3.ggpht.com/_QMRLyAEclGA/TLfg29ooMPI/AAAAAAAAIZw/p9nXdjr6ruE/s800/2010-10-14%2011.31.32.jpg" height="600" width="800" /></a>

    Cleaned and painted the air box, then Aivars and I spent a good 10 minutes trying to figure out how the hell it fits.
    <a href="http://picasaweb.google.com/lh/photo/YYS6pH0A9WsCTAoP4wTBow?feat=embedwebsite"><img src="http://lh3.ggpht.com/_QMRLyAEclGA/TLfhb97ME6I/AAAAAAAAIZ0/F3MhXUfOxeE/s800/2010-10-14%2018.27.39.jpg" height="600" width="800" /></a>

    Got the forks painted and installed. They need to go up a little further, but I'm having trouble with that.

    Then I figured out where that strange black plastic bucket goes. Not sure if it's just supposed to be a storage spot or a battery holder...
    <a href="http://picasaweb.google.com/lh/photo/FwYV8ZuPX5IOTyBiRlBXKA?feat=embedwebsite"><img src="http://lh5.ggpht.com/_QMRLyAEclGA/TLfh8j97hDI/AAAAAAAAIaA/RuRG2EbBnhk/s800/2010-10-14%2019.42.38.jpg" height="600" width="800" /></a>

    Front fender mounted. Note Rider Adjustable Fender Height (RAFH). You can set it all the way down for flat-out assaults on your favorite open highway (at speeds approaching 43mph, you are going to want to minimize lift.), or set it all the way up to allow for full travel when you plan on catching some big air.
    <a href="http://picasaweb.google.com/lh/photo/YthOkL5eDPuKpxuw0cNFVw?feat=embedwebsite"><img src="http://lh6.ggpht.com/_QMRLyAEclGA/TLfiOxQ_UdI/AAAAAAAAIaI/CMQblTXZ26I/s800/2010-10-14%2020.44.19.jpg" height="600" width="800" /></a>

    Rear fender installed, and front fender mudflap installed. That front mudflap is sweet, it says "MHNCK" on it
    <a href="http://picasaweb.google.com/lh/photo/8lKFffQTUZotkHtLwpA_NA?feat=embedwebsite"><img src="http://lh6.ggpht.com/_QMRLyAEclGA/TLfigkn8KrI/AAAAAAAAIaM/3smvjeHxtLo/s800/2010-10-14%2021.00.52.jpg" height="600" width="800" /></a>

    Figured out where another plastic bit goes. See that thing on top of the rear fender? I don't know what it does, but that is where it goes. Also got the front wheel mounted, but its wrong, I'll revisit that tomorrow.

    I just spent an ENTIRE weekend (well, sunday's still up for waste yet) making two chairs out of pruned maple branches from my back two acres. This, from what looked at first to be a one hour job with a sawzall, hammer, and nails.

    Of course, along the way I had to find JUST the right curves and bends in the parts, mortise/tenon the joints, use deck screws, and otherwise totally fuck with the plans I'd swiped off the net. I was finally surveying the damage to the shop and my weekend when I stopped in here and caught up with your thread.

    Thank you. Thank you! Some bad ideas certainly do end up worth the adventure. You are an inspiration.... of sorts. :beer

    Yesterday Larisa and I went out for some rain riding, I took Aivars' KLR, and she took the KE100. When we got back to the house, I wanted to try to get the front fork mounted properly, as it was just kind of mocked up for the pictures last week. First I realized that I had no ball bearings for it. I had assumed that they were in the big heap of parts somewhere, but no. I am guessing that when they disassembled the bike, the ball bearings went rolling across the shop floor, and the mechanic just sort of shrugged and kept packing.

    So I need new ball bearings. No big deal. I called Derek at Motolab to see if he could help me find the right ball bearings. For some reason he is always willing to help me out, even if I'm working on a Minsk. As I am talking to Derek on the phone I am removing the forks, and the bottom race just sort of falls out. But whats more, when it falls out I notice that it has a bit of aluminum soda can wrapped around it to shim it in place...

    <a href="http://picasaweb.google.com/lh/photo/7ySx7r5Fn1C0dV87UtrXww?feat=embedwebsite"><img src="http://lh3.ggpht.com/_QMRLyAEclGA/TLxshIiyPoI/AAAAAAAAIak/uA0lKyFShx0/s800/2010-10-17%2017.19.07.jpg" height="600" width="800" /></a>

    When I put the race back in without its custom soda can shim, I am able to move it back and forth about 1/4", and probably 1/32" left to right. Take the race out and look at the bottom of the head tube and you can see that it is an oval.

    Great. I briefly consider not telling Derek about my little discovery, because I know he is going to make me fix it correctly, which means real work. I tell him about it, then start asking him if various idiotic ideas I have will work, and he patiently explains why each one of my ideas is terrible. "Can I just weld the race in place??" and "Can I just cut the head tube off and weld another one in its place?" are two of my brighter suggestions, but he is not amused by either. So I put wheels on the bike, roll it into the Sprinter, and bring it to Derek. He looks slightly horrified when he sees it in person.

    So Derek has seen it, and now he is figuring out what will be the simplest way to fix it, but it sounds like no matter what I am going to have to strip it down to a bare frame again.

    In the mean time, here's some pictures of it when I wheeled it out of my garage

    I thank you sir - this Brit had never bothered to find out that the theme tune was not an original score.

    Now enjoying the Allman Brothers Greatest Hits :clap

    And keep watching Top Gear - what they do to caravans is a thing of beauty :evil

    And thank you Mullet5 - your thread was linked via UKGSER by one of our tossers.

    those Minsks are Great arn't they!!!I've had a few Voskhods in my time ,a Jupiter 350 twin and a Planeta 350 "Sport Single" They are pretty easy to work on but I found parts to be a real problem ,even with contacts in the former ussr some bits were impossible to get.I love this thread though ,takes me back to being 17 years old when the Voskhod 175cc was my only bike!!!!
