Fastener Summary. A variety of fasteners can be used to assemble the arrayer. Parker may or may not send you all the right ones. It's wise to have a a stock of extra bolts of many sizes on hand. Make sure whatever bolts you use for a particular purpose aren't bottoming out.
The econo fastener tabs in the diagram are used to hold the Y-stage adaptor plates to the parframe. They can be set into the parframe grooves with tweezers, or by using a wire to get underneath them. When dropped in by hand they don't fall flat but need to be rotated slightly such that they fall into place. With the parframe flat on the table, the fasteners can be aligned roughly for the spacing of the adaptor plates.
Lift the Y-stage onto the parframe and attach with M6x12 bolts. The bolts should be just long enough to be able to "pick up" the fastener with rotation as the fasteners sit in the grooves. When trying to pick up fasteners in this way when you don't have direct access to the bolt with your fingers, a nifty method is to rotate the bolt counterclockwise until you sense a click as the threads rotate past the point at which they would catch if rotated clockwise. Once you sense the click, rotate the bolt clockwise and it will almost always pick up the fastener properly. As always, take care to avoid cross threading. |
