    Started this winter with a oversized MTB kit from nova cycle supply....

    Made a jig, and cut all the tube to length..,

    Geo 1070, 380, 35, 72HA
    Frame Weight 4.2 lbs

    Also made my own V-brake LGM holders because of clearance problems, they had to be custom.

    This has been slightly easier than my first attempt, because I bought the tubing kit with bent cs and ss.

    So far so good, can't wait to ride!

    That is so cool. I have always thought it would so fun to build custom bikes, get everything the way you want it. I'm sure it takes a lot of planning and skill. :bigthumb: Nice Job!

    Looks good, Alan! The weight came down a lot from the last one, didn't it? Is that pea soup? :barf:

    That...is everything you could want in a frame, especially like the bb yoke and rear dropouts :drool:
    A world apart from the last one, quantum improvement, looks tits in white!

    Love homemade frames & parts. That bike looks great but we need a complete shot from the side.

    Were you not able to get the pads far enough down in the arms?

    Keep fabricating & updating us.

    Here's a side view.
    [​IMG]

    I just finished the brakes and drivetrain today. Almost done. Hopped around in the driveway a bit. Very stable on the rear.

    You guys have any suggestions on the stem height? I am a short dude (5'6") and find the high setup very comfortable. Does it just look dorky? I did put proper spacers in today.

    Thanks for the comments.

    Oh, my first problem with with brakes was that I was determined to use that booster. It has a max separation of 93mm. I would have liked 100mm. And second, I put the vee posts 10.25" from the axle. Should have been more like 10" even. :dunno:

    Those pad backing look awesome... i could have sooooo used those when I rode this fabricated ti mod back in the day with the brake posts just a bit off... great idea! why move the posts when you can just make backings with an inch offset lol

    For the bar set up I would get a slightly longer and higher stem 135mm maybe, take a few spacers out from under the stem and cut the steerer accordingly, keep your bars they look really nice, and tilt them back towards you just the tiniest smidgen to keep the height. This will give you the room in the cockpit you are looking for with the stem nice and low out of the way for hooks and tucking. This is what all the elite riders use pretty much. Obviously buying a new stem and cutting your steerer tube might be a little unnecessary when the setup you have now might be more comfortable as you mentioned. But you did ask so... lol.

    Amazingly nice looking with that white paint. Love the look of those newer frame dimensions with the old-skool thinner tubing. Very cool bike!

    how well does brazing work like that? i thought you had to use lugs for a bike frame.

    My brazing is with Nickle-Silver wire ( which actually has no silver in it ). It is nearly as strong as steel and with some careful torch control you can build it up to make a nice fillet, like welding.

    The stuff most bike builders use with a lugged frame melts at a much lower temp is commonly called silver-solder. It is very runny and does not build up well.

    And, my lunch was Tandori Chicken, not pea soup.:barf:

    Now, If I could only tap, gap or sidehop, I'd make a video...

    very nice. I was quite proud of myself for making a custom booster! I would think that would feel real good riding on a whole bike you made.
