    Aluminum vs Magnesium

    Any difference with magnesium parts? I just stripped the ano off my `05 Dorado crowns, thinking it was aluminum, and then came across an article saying they`re magnesium. Looks like raw aluminum to me.... polishing up nicely. But worried I may have made a mistake, the whole thing will collapse under me, etc.

    Any one know? I have no freakin idea...

    If it looks like raw aluminum and it is polishing up nicely it probably IS raw aluminum because you cannot produce a high shine on magnesium. You can clean and remove oxidization from magnesium, but you cannot polish it. My guess that your fork lowers are magnesium and your crown is in fact aluminum.

    You can not anodize aluminum. It must
    of been some other type of finish.

    Wow. A whole new paradigm!

    I`m guessing you mean, `You can`t anodize magnesium`, which is really useful information and I thank you. If you do mean that aluminum can`t be anodized, then all I can say is, Welcome to Earth! We do things a little different on our planet!

    Magnesium can be anodised, although I believe it is for paint priming or low-evel corrosion protection. Of course, you're correct about about aluminium - anyone who's ever thrown their leg over a modern mountain bike knows that aluminium can be anodised, and anodised into an array of lovely colours!!

    My bad, I did mean magnesium. I should know
    better I worked in a shop and anodized parts for
    over 25 years. I've never heard of a type of anodize
    for magnesium, but we use to use what is called
    a sodium dichromate finish. It came out a dark
    grey. Also you can polish magnesium, it just
    doesn't come out real good. The term mag wheels
    for cars is because they use to be made out
    of magnesium. If you look at old photos of cars
    some of the wheels are polished.

    Best, John

    Finaly got around to stripping my Haro Thread 8 Dirt jumper

    Previous owner had rattle canned it without even taking the headset or the BB out.

    I was a little tentative to take on the project but it went quite smooth. 1 week's worth of allowance (30 bucks) bought everything needed:

    Jasco epoxy/paint remover
    good gloves
    paint tin
    brushes
    drop cloth
    steel wool
    plastic bristle brush

    Like i said, things went really well (only 2 chemical burns, should have put on pants not shorts!)
    the jasco stuff is powerfull! Don't hesitate! try this yourself!






    The jasco tin says 15 minutes but within 2 minutes i could hear the popping and crackling of the paint bubbling off:


    that was one coat of jasco (quarter tin at most) but i had missed quite a few spots - washed it off with water and did another coat of jasco





    water and soap gets the goop off

    all done! (polished with coarse then medium steel wool) (cat not part of the project)


    Out, out, brief candle!

    I stripped the frame with Aircraft stripper. Sanded with 220grt-1500grt wet sandpaper. Then buffed it out with Mother's mag polish, and a terri cloth.

    After all the mud, that's how nice it comes out every time it's cleaned.

    The frame is like a mirror, no scratch marks whatsoever.

    Yeah it's old school. It's a 1995 Gary Fisher Paragon. Now that GF is no more I kind of wish I left the paint on it. Oh well it still looks way better than it did.

    Their are some pics on the first page of this thread. But here's one for ya.

    Those polished frames look so dope, I think I´m gonna do that when mine is too beat up too.

    Don´t forget to clear coat it, aluminum don´t like water (hydolysis or something) try putting water in a raw aluminum pan for a week and you´ll see.

    The best things to polish aluminum with is toothpaste and ketchup, Not at the same time. And thats no joke either. You get much better finish than the commercial pastes, and faster.

    Toothpaste is a mild abrasive so it makes sense that it would polish aluminum. Ketchup???? I don't get it....

    Me neither but the guys who polish nose cones of turboprop engines like it, and they do a lot of it so who am I to say its not true.

    Needed a place to post pix and not sure where it belongs (bike thinks it's a DJ, I think I freeride but both prolly AM ).

    KHS DJ50 POS, my first 26" but barely better than an entry level, it was yellow and a few nooks still are.

    Rims, cranks and a few other things have already been replaced, eventually, it all will be.

    Ok. I stripped my front triangle on my full susser with aircraft stripper. Took me 1.5 hrs to get it looking very clean. I want to strip the paint off my rear triangle but I do not want to damage the bearings. Can I strip the paint while keeping the bearings in place? Will the paint stripper damage the bearings? Or should I just leave it black?
