Directions on threading the holes on the wheel deck for the Plus version of the rig.
You will need an M8 tap, tap wrench, and lubricant.
Install tap in handle
Spray on or dip tap in lubricant
Begin threading in (Make sure you are threading in straight)
After Making a couple turns, back off a small amount and then continue
Half way through, remove the tap and spray the chips off with lubricant
Reinsert and continue until you have reached the end of the tap
NOTE: Do not apply too much pressure. If there is a ton of pressure back out a bit or add lubricant. You do not want the tap to break off.
