This is as far as I'm going to pull the handle off. ....cause it will be a PITA otherwise
Closer look at the 140mm top exhaust grill
4x screws fasten on the steel portion of the handle. Notice it has large tabs that slide into the top of the chassis.
I'm using this 120mm wire fan grill
to find the center of the perforated grill
Greenlee Knock out Punches
Greenlee part # 730EBB-120
Last time I inquired, they were around $450 (us dollars) in the states + Large 3/4" socket wrench, and 2" socket. I wouldn't use anything less than 19" long socket wrench. Estimated purchase price of $550 new. These are primarly used by Electricians and sometimes Plumbers.
Back to removing the Scout's top perforated fan grill.
In order to fit the Greenlee's knock shaft into the grill, I cut a 1.5" opening in the center of the perforated grill with a heavy duty wire cutter
You first insert the threaded shaft
I'm using a 19" long 3/4" socket wrench to turn the blade
Within a matter of minutes, a clean 120mm size hole is cut.
The center of the perforated grill
I will have to buy a 140mm size knock-out blade soon
