Best wishes too you Giles, sorry about your brother. Your work is a great inspiration to many of us and I'm looking forward to this little project progressing.
Cheers

I’ve just caught up on your thread Giles and am very sorry to hear of your loss. I do hope your modelling will provide some solace.

Rather than a hook, can you put a clamshell bucket on it?

A day spent on the drawing board and on the laser.....
The front crane beam with the jib clevis
the crane footplate precut for slip ring, on off switch and charging socket. The angles to either side have been replaced with fold down elements enabled by laser-cut fold lines.

Giles, I see that some N20 motor/gearboxes have the output shaft at 90°, which on the face of it lends itself to driving a locomotive. But this would require a replacement shaft of the correct diameter to suit one's choice of driving wheels. Have you ever stripped one of these gearboxes? If so, any issues?

I've not stripped one. Most have the frame spacers riveted over, but that's not insurmountable. There is also a variant with a double sided output shaft. (3mm dia) which would be more suitable for direct drive.
Don't loose any bits and take photos if you try it!!
Dave (aka Ruston) uses the conventional N20s and now N10s a lot with crown gears for final drive very successfully...... I've shoved many in vehicles with bevel gears......

Indeed - put it down to my memory!
In my job as a Theatre Consultant (Stage Engineering) I got to deal with all sorts of problems. One of my last before health forced retirement was a commission to find a solution to an urgent design problem on a new Theatre being built. It was a major 750 seat Theatre in the West End that could play in the round, thrust or end stage, with audiences three levels - stalls, circle and balcony. Drawings were approved for all layouts and groundwork were underway, but no solution had been worked out for transitioning between formats - which consisted of removing 65% or more of the balconies at both upper levels. The only plan on the table was to bring in construction crews and de-constuct them over a period of however many weeks/months together with associated sound, lighting and communication wiring etc..... A normal turnround between shows is a week/ten days (more in the West End of course...)
My job was to find a way to do this fast.
The solution was to make the balconies into modules each including seats, rails, lighting bars, carpets, all wiring, house lights.... everything... that could unplug, unlock, and lift off its bearers, and drop down onto stage and wheel away into storage.
The bearers were heavy profiled swinging arms that would (once unloaded) swing back into the wall between the structural columns on which they were mounted, out of the way and out of sight.
To lift each balcony section, I hijacked the anticipated lighting bridges, and redesigned them as mobile gantry cranes with travelling wire hoists mounted to the underside to do the lifting and travelling in the X axis, whilst the lighting bridges travelled on their own tracks in the Y axis.
This enables a reconfiguration in around 24 hours.
Obviously the principle was initially tested with mockups
