    A selection of previous and current builds

    Normally the gas for mig and tig are measured in volume not pressure, a correct gas setting should be about 15-20 cuft/hr or 8-10 ltr/min. 15 psi sound to high for me, you probable blow away the weld with the pressure build up, try lowering the gas down until you just hear a faint hiss. Try...

    Hybrid handcycle for wheelchair

    Hi Yes, I (we) can help, the question is, do you have your own workshop?, what's your budget? do you want e-assist?, do you have a donor bike? The cougar construction is based on a lengthened head tube, not to difficult, and to fit a bottom bracket instead of handle bar, not to difficult. The...

    Project chopper

    Did some digging on the net and added a thumb throttle and speed sensor, I also changed some parameters in the controller. Now I have power, can do wheel spin with the thumb control, I also tested different control units and got it all working. The additional speed sensor was not needed, there...

    Project chopper

    Got the electric sorted. Didn't work at first. All cable as they should be, but nothing. There was one, two cable, connection not in the manufacturers schematic. My suspicion was that it was for a on/off switch, so I put some mig wire across it, and it worked. I do like the torque sensor, it...

    Project chopper

    I bought a bottom bracket with built in torque sensor, so that would eliminate any extra sensors. The motor is controlled by the torque sensor only and will not run before I pedal, so I presume that the motor disengage as soon as I stop pedal. It also gives a signal if I pedal in reverse but I...

    Project chopper

    My progress is slow but steady. A project I wanted finished in spring 2019, is far from finished. Here is a update: I mounted two bends to the bottom bracket to finish of the frame. It slow progress because all the cables will be routed through the frame. The black cable taped to the frame...

    Fat wheels.

    Have a look at the cycle cart forums. https://www.cyclekartclub.com/ Small racing cars using honda cub or pit bike wheels. If you leave out the motor and add pedals you get a quad that's up to your spec. The frame is made from 3" x 1" x 1/16" tube so it's light weight and strong.

    Ed's 'StreetRunner' Quad Build

    On more thought. Measure with a volt meter the DC voltage between the positive pole on your 12v DC/DC converter an chassis to check if it's 12v.

    Last line is wrong, do not connect black cable to P before you know it works.
