Note: New service.
I may be able to provide some custom CNC service, depending on the size and if I have the time available. I can easily make custom torque arms and brackets. I can cut steel but wish to avoid any stainless unless they are the easily machinable ones. Composite work as well but this can get costly. You may need to supply the materials since I don't care to stock or order them. PM me about a quote or email me at email@example.com

It's getting harder to keep track of all the many good threads I'm interested in and also to keep the threads I started current. This is my place holder for my projects and what I find interesting on ES.
My first ebike and what it has evolved into.
Originally a DiamondBack, Cyclone 650watts and Dewalt A123 packs it's now a GT Polamar after the frame broke from repeated jumps.
It's used mostly for errands and getting groceries, I have a side bag I can mount for this. I also use it for the trails if my main bike is in service and this frame won't break, Chromoly.viewtopic.php?f=3&t=6348
My second ebike built specifically for trail riding. I have a blast with this ebike every time I'm out trail riding and look forward to the next ride. It's been ultra reliable, just flats to deal with now.
Motobecane DS Fantom, BMC 600W V2 torque and Konion build. The main pack is 8P 10S setup for a 12ahr in the triangle. Another equivalent pack in the rear rack making a total of 24ahrs. click on pics to enlarge.viewtopic.php?f=6&t=12654
