The provided tubes all have the correct length. If you start cutting tubes than you run into problems later on. I have build this set multiple times an never run into problems. Make sure all tubes are routed correctly and by the shortest distance sometimes its needed to route a tube underneath another. When you start building, what helps is sorting the ...

BrickLink says that it's called the "Pin with Friction Ridges Lengthwise WITH Center Slots." However it may also be the "Pin with Friction Ridges Lengthwise WITHOUT Center Slots."

Dang, oiling stuff is a problem. Probably your best bet is to try to power-wash it, or apply some sort of oil remover. As for the rust, the oil (how great is this) should keep any from happening, if there's any remnant.

If anything breaks, the gears won't primarily be the problem. Do I have to worry about breaking any gears due to excessive torque? Do I have to worry about gears slipping (skipping teeth) due to high torque? I have seen gears get to nearly twenty N.cm without issue, other than slipping along the axle, (easily fixed with bushings), or skipping, ...

The pneumatic system's limit is three bar (40psi). After that point, the hoses will pop off the ports. I don't think you could explode the airtank very easily with a real compressor. My guess is that it would start deforming around the 5-10 bar range, and only explode once it was bordering on spherical :P.

I have never broken an axle. That's despite dealing with some rather hefty forces that dwarf any LEGO motor. I made a flywheel (around 800g and 8cm radius) and spun it by hand up to 1,000 RPM (through a gearing system and a monstrous handle). That's 28 joules of kinetic energy there. I then released it all into a single wheel (with more gearing up), with the ...

Simply put, they won't break. I've put LEGO gears through everything I could and they were fine. That includes spinning an 8-tooth gear at around 80,000 RPM (sustained for only a second or two) via a flywheel-based stored-energy device. I've driven a 9lb vehicle with about 40 gears in the drivetrain, and none broke. Slipping teeth is rather common. As a ...

I would suggest you use 10 of either one of these: 4273 Technic, Axle and Pin Connector Toggle Joint Toothed or 4273a Technic, Axle and Pin Connector Toggle Joint Toothed - Without Slots, together with 5 equal length axles and 5 pins. Creates a sturdy pentagon. Use the pin connector hole to attach the pentagon to other structures. If you don't want ...
