Thanks John!

Lewis, I love the idea of a duel. However, a duel might not be possible if we can't fix the pretty catastrophic failure we just had...

The cotter-pin system for the lifter-motor-side sprocket has been a pain in the behind for a day or two. Tonight we got a cotter in and it all looked good (having completely sheered the previous one; the torque in this big drill is other-worldly) so we stuck the Tormenta 1 remains on the front and gave it a lift. After a few bashes there was a snap.

The reverse thread screw that goes into the drill shaft (essential to the setup) has completely sheered where we cotter-pinned it.

We're working on a potential solution, but let me remind you that we are leaving on Monday morning for Germany. We have more or less everything involved before a 3 week roadtrip to do before we leave.

If we can't do it, we may have to call Germany or maybe even the whole trip off. No point in travelling 1600 miles to Dortmund to fight a weaponless robot.

I'll keep this updated.
