    Listen! 36.6

    So bike number six will be a 36er I know I know make something different already, bike 7 will probably be a 29+ but for now three foot wheels. This one will be 7005 tubing same geo as 5 the only real change is the tubing diameter 1-3/4" DT and 1-3/8" TT I may change the CS
    Diameter but dont have the bending dies for 7/8". I mght try some real
    chain stays grafted to 3/4" to get the required length. No pics yet but will post some soon!!!

    Merry Christmas....O...wait may not be allowed to say that so Happy Holiday's everyone!!

    Look pretty perfect!
    Care to share some geometry? You have a ton of experience riding these it seems and would love to hear what you've learned through your builds on what works and doesn't!

    Thanx

    the geo is
    71.5/73 HT/ST (I have to use a setback post to get to 73*)
    770mm FC
    24 5/8" TT
    18" ST
    520mm CS
    510mm AC

    The biggest hurdle is the wheels you have to get around, over and thru them bad boys. So to get the shortest chain stays you have to interrupt the seat tube either by
    bending it or choking up on the DT I like the looks of the radius tubes. The DT is next
    some can get the front tire to clear with a straight tube when I tried it was to close.
    So to the radius bender with that tube also. With this tire size handlebar height is starting to get high so I use the shortest headtube possible with inset bearings.

    Is this one for you? FC always looks whacky on these. That tire is waaaay out there.

    What is the fork offset and resulting trail?

    Thanks for that!
    How tall are you? Is that the 'minimum' frame size that can handle the wheels in your experience?
    What trail figure are you getting shooting for? What fork offset are you using?
    I'm using bikecad and it seems like I'm not getting the same overlap issues on the front end but definitely am on the back end with the seat tube even with bending it a bunch.
    What is the diameter and width of the tire you're using?
    Sorry for all the questions or if I missed the answers in a previous post!

    Yea Matt this frame is going to replace my current aluminum bike, the rake I'm running is 80mm but Ive never figured out trail and I haven't experimented with
    Rake Walt recommended this rake when he built me a fork and it works very good

    Ah....forgot about standover very good question the TT rises fast to clear the front tire so the boys get crowded this is something you'll have
    to compromise on. I made a small (15.5") if you can call it that.

    36.6-dsc00438.jpg36.6-dsc00440.jpg


    Also Walt's blog has some great info on 3 foot wheeled bikes! The wheel diameter with tire is not quite 36" the widest part is 17 1/2"
    from center this is with the Vee rubber tire I would definitely get the
    rear wheel tire combo before you start

    Todd,

    Theoretically, assuming your walls are about 1/16'' (1.6mm), the 7/8'' tube has 141.8% more Section modulous (strength) compared to the 3/4" tube !



    What was the size of the chainstays you were using on your other steel 36ers ?

    Keep up the good work !

    I think this blog post from Walt does a good job answering a lot of questions :

    Nice miters, looks like that cheap HF tubing notcher works well on aluminium.
    Have you tried the tubing notcher on thin wall steel tubing yet?

    Do you mean like a CK large diameter gas lens?
    Gas Saver front end accessory kits from CK Worldwide Quality TIG Welding Torches & Accessories
    I've tried it and not loved it so much.
    I'm now using a #12 cup and large diameter gas lens and stubby backcap, I am getting used to it.

    Also I found some 7/8" tubing at a hardware store to see if it can be bent in a 1" die and it didn't do to bad.

    Looks good.
    I'm not sure if I'll ever get one of those, but it's good to know it works.

    Well I ordered a new 7/8" die for my JD2 bender and some dropouts from Kavik bikes I was originally going to use the drops from my current frame but change my mind.
    Maybe some updated pics early next week.
