Foam & carbon

Posted on December 7, 2010 by Mik Efford

Tune in, drop out

Posted on August 6, 2010 by Mik Efford

I’ve completed the wrapping of the drop-outs with sisal. I’ve also added stay support bars near the bottom bracket and seat-post to give the frame more stiffness. Here’s some pics: The clearance between the last cog and the chainstay wasn’t … Continue reading →

Posted on August 1, 2010 by Mik Efford

Started wrapping the sisal twine around the joints tonight. Here’s the process for the seat-tube. I’ve done it in two layers. The first using lengths that run lengthwise down each pole, following the curves of each filleted corner. The second … Continue reading →
