Spacers in FIRST gearboxes
The latest exploded diagram on the FIRST doc pages shows "spacers" being used along with the locking clips and key stock to assemble the gear boxes and make sure the gears don't drift off the shaft. Has anyone found a good way to make these spacers if you dont have a machine shop? Iwas thinking maybe 3/4 inch pvc or other plastic pipe. A whole bunch of washers is messy and adds too much weight.
Also is it just me, or is mounting the gears with the supplied keystock a bear? Seems the key stock is harder than the shaft but softer than the gears - is this the way it is supposed to be, or is there some magic tempering trick? |
