Overview
A basic guide to master Stock Bearings!
What is a Stock Bearing?
A Stock Bearing (Also known as Stock Motor) is as the name suggests, a bearing that is stock (without Mods). The concept is simple. You have a tube of some sort that rotates in a cylinder or a cylinder that rotates around a tube. They are usually powered by rockets or reaction wheels.
Often they will use wheels to reduce friction and keep it stable.
Making the Bearing
Making a bearing can be time consuming and annoying but always remember that practice makes perfect!
There are different types of bearings for different uses. The one that we will create will have a stationary case and the spinning bit will be in the middle.
The first step will be the tube that will sit in a cylinder. First place an OKTO2 probe core, then place some batteries on that then top it off with some Small Inline Reaction Wheels! Then place LY-05 steerable landing gear on two of those batteries with 8-way symmetry. Then use the offset tool in the top left (or just press 2 on your keyboard) and inset them into the batteries. Right click on the wheels and set Friction Control to Override and set Spring/Damper to Override. Set the friction to 0, Spring Strength to 2 and leave Damper Strength to 1. Make sure to also disable steering. Now hold ALT and click on the base battery to dupliate it then put it on the other side of the probe core. Now put the FL-A5 adapter on the batteries. WooHoo! You are done the rotating bit of the bearing!
Now for the casing! Take a stack seperator and place it on the bottom adapter and set the force to 0. Then stick 2 structural fuselages on the stack seperator (you might have to clip them into each other with the offset tool). Use the offset tool to move the stack seperator to the left then move the fuselages so they are encasing the batteries but not the adapters. Now attatch some of the LY-05 steerable landing gear onto the top and bottom of the fuselages so that when you detatch the stack seperator they hold the weight of the rotating bit. Make sure that all the wheels have no steering, no friction and you have set the Spring Strength to 2. Now make sure that the wheels will ride on the adapters and that the inner wheels arn’t clipping into the fuselage. You will probably need to tweak a bit but you should now have a working Stock Motor! All you need to do is put the casing on some launch clamps and decouple and you are good to go!
