9.1 – Assembling the Carriage Rollers
For this task, you'll need the following components:
The carriage rollers are made from two bearing sleeves and a single R4ZZ bearing. You'll need
to apply sleeves to all 12 bearings used in this step. The tolerances on the sleeves are VERY tight.
They may also have a sharp lip on the outer face. You might want to use some of the scrap Melamine
to help you press the sleeves on to the bearings without leaving a ring on your palm.
Start by laying a sleeve half on the table, face up.
Set an R4ZZ bearing into it and firmly press it into
place.
Now set another sleeve half on the table and press the R4ZZ bearing and sleeve into the new
sleeve half to complete the carriage wheel.
