    Not totally sold on the raw aluminum look but I can't deny its functionality.

    76 years of oxidation can be harder to get off than paint.

    No, it's aluminum. Yes they had aluminum bikes in 1936. I will oxidize if you don't polish it once in a while.

    It's going to rust. That's why it was so hard to polish.

    Really? The first photo was taken 3 years after I built the bike. I didn't notice any rust. I know bare aluminum will oxidize if not properly cared for but I use a polish followed by an automotive polymer that creates a barrier from moisture called liquid glass. I have not had to polish it for quite a while.

    That's amazing those thin tubes are aluminum, from 1936!!
    That frame must be worth something.
    Great job polishing it.

    my 2 cents: aluminum doesn't rust unless you call oxidation rust, but rust normally refers to iron oxidation, not oxidation in general.

    How about some pictures of the dog in your avatar? I love bull breeds.

    Very nice bike. How about some history or the build specs?

    Aluminum can oxidize, but only iron can rust.

    I'd like to know how that thing is held together. There are no welds visible around those lugs!

    The tubes are press fit into the forged pieces. It is a 1936 Wards Hawthorne Silver King. I got the frame for $100 bucks and the steerer tube was separated from the fork. This was a common issue. I milled another from a modern 1 inch steerer tube. The seat post was another challenge. It works just like a quill stem with a bolt and an expander to keep it in place. Finding an original is impossible so I made one out of a piece of aluminum rod by boring out the center and using an old quill stem wedge and bolt.

    It took lots of wet sanding down to 2000 grit to get a good base for hand polishing. The rims are vintage Araya 7x that I also polished. The front drum hub is an old Sachs and the rear coaster brake is a Morrow hub from the 40's. The cranks, truss rods, rear hub all came from an old Elgin. The stem is a Suntour, the saddle is a Brooks.

    Nice work! How many hours sanding & polishing to get it (just the frame) to that stage?
    I see hills.

    I want to climb them.

    This thread got me dialled in stripping the paint of my (modest) bike.

    My first attempt at doing something like this,most of the work done using chemical paint stripper and steel wool except for the dropout area where had to use a drill with steel brush.

    Have one question thought: I tried to use the woven cleaner trick to strip the anodized from an aluminium seatpost and it works reasonably well but the laser etched logos and lettering remain on bare aluminium, although not so much visible cant seem to brush them off. How deep can this laser etched things remain on aluminium?

    FMCurto, your bike looks great!

    I don't have the experience to answer your question about removing the laser etching, though.

    They come up on ebay and craigslist every now and then. Frames usually go for about $100-$200 bucks. My total investment on that bike was only $700 dollars. I have had offers on it up to $2000.
