    Went to the wreckers today and removed a drive shaft from a 3 series BMW for my universal - cut to size with hacksaw and welded to steel plate from local hardware store (Bunnings). photo's show trial position , need a hand to find balance point.

    Got the motors today upload_2019-9-28_20-18-49.png upload_2019-9-28_20-19-24.png

    Punched the rivets out of the gearbox and used a hole saw to cut hole for the shaft on other side of gearbox and made into lefthand box. Metal gears looks solid no backlash.

    I should have ordered left and right hand gearbox in hindsight. :)

    Open gearbox - brass gears is a good sign.

    Pipe sleeve bolted to motor before welding turning arm. ( Don't do this, it needs to be a key way or you will get to much play, I learnt the hard way).

    Mounting motors and turning arms - checking motion limits, roll 12 deg, pitch 8 deg.
    Not sure if this is normal?

    Finally got back into it, the Monster Moto Shields took 2 months to arrive, lucky I ordered 4 as one was DOA . I suspected as much when the motor moved, even when I had turned all PWM to zero. Luckily the other one worked as expected and I used it to test both motors and pots before changing to a new Monster Moto Shield. All tested ok with SMC3 so setup on simtools demo and LFS once I got the interface working with help from https://www.xsimulator.net/community.

    Below is the wiring setup I used to parallel up chips and increase current handling thanks to another helpful post.

    Next issue - these couplings have to much play I need to use the key way. (it bent the stainless bolt) I should have known better but was in a hurry to get it all working.

    Heat sink temps on chips.
    I'll put grommets in holes and tidy up cabling later, but keen to test out first.

    My test pilot (wife) still seems a bit jerky. (maybe the driver) ;)
