    Re: tubing size

    Hi Gphil,
    As FrankCrank says, the plans utilising 1 &3/4 square 16 Gauge steel are more than adequate for most folks. I have made one out of steel twice the gauge and it was awfully heavy as...

    It is not clear to me what specific issues were encountered with the chain idlers but I would offer this bit of my personal experience.
    I lost an idler mid-ride last year (I managed to pull...

    Re: Building a python trike Mk2

    Paul,

    No matter what you do now, you either have to accept a "hammer-fit" as you put it; Or, place sufficient packing between tabs and seat-frame spine to allow an easier fit that can then be...

    Re: Building a python trike Mk2

    Paul,

    Re: Danny's Daily Delta

    Another "first".
    Today I managed to tig-braze a cable stop to my frame.
    Just a blob of silicon bronze at either end. Can't knock/pull it off the frame, so it must be ok.

    I think you are right Frank.
    I only ever tried the "as per plan" Street-Fox style seat once and that was enough. Uncomfortable, and I just did not feel secure in it.
    I never looked back from the...

    Today's Progress:

    Because of the "twisting" forces on the steering column I made a pinch-bolt sleeve and welded it to the intermediate tube, so it can now be done up very tightly with an M6 bolt....

    Re: Winnipeg Highroller

    Hello Hugh,

    I like the Bafang very much. Mine is a BBS01 unit and I have modified it to provide a double 52/39 chainring.

    Re: Tall bike child transporter or Velomobile

    Hi Alex,

    Re: Danny's Daily Delta

    So, purely as a test to see what it might look like I put it in the headset and fed a tube through to see how good/bad it might be.

    I didn't feel the upper seat clamp was sturdy enough (i could see the 2mm clamp plates flexing), so I made a new one all in 3mm plate like the lower seat mount.
