8.1	104
13.1	105	Considering different applications (high forces, low forces, pushing or pulling) the assembly follows slightly different paths. Generally, assembling the load frame can be broken down into these steps:
12.1	106
13.1	107	* Install a base plate on the rotation stage (use spacers, decide which plate to use)
	108	* Mount load cell on base plate with desired pin or clamp (depending on push or pull experiments)
	109	* Mount sample tube (choose the tube type according to your application)
12.1	110	* Mount pusher
