This assembly, although only consists of 4 parts, is vitally important for the rest of the machine, since everything else is attached to this part of the build and it is important to note the correct orientation and hole positioning when assembling. Any mistake here can lead to time consuming efforts in disassembling the machine and doing it all over again. All tools that you shall need for this part of the build are already provided, so there should be no problem in putting this part together, with the help from these instructions.
