Using the mold parting lines, I cleaned up the edges to fit up the Cannon & Co. long hood end.
So now the radiator screens are ready to fit up and the long hood end is ready as well. I will now go back and
work on the radiator fans. As you have already seen, I have reamed out the fan grills. Basically I drilled a hole
down the center and just stuck the reamer in there and turned it until the grills were gone. As yo can see from
the photo below, it does a pretty good job and it is fast. Just make sure you keep it as centered as possible. It is
easy to adjust your cut one way or the other and use the fan grill circles as a reference to keep it centered.
After the grills are reamed out I break out the nippers again and nip the fan guard down to the mounting base.
Through all these operations, take care to not disturb the fan plate bolt heads. That is key!
Now I break out my very small chisel blade. This is a great tool. I got it from Micro Mark, part #81067. I use the
#61 blade (part #81084) which is about 1/16" wide. I cut the remaining fan shroud down to the fan mounting
plate. I then scrap it flat. This knife is great for getting into tight areas so yo do not destroy other details.
I did not want to take the fan base all the way down to the fan hatch surface just yet. I need it as a reference
for opening up the holes to fit the Cannon & Co. fans.
Another good reason to show you this photo is to explain about how much more I need to open these holes.
You see the flat of the circle where the fans face each other. You want to open the holes just about to that flat.
Almost right on it. Trust your eyes when you are opening these holes. That is why I left the fan base visible. As I
am opening these holes, my eyes can tell when I am out of round and where I need to adjust my cut.
Once again using my drill press on the lowest speed setting, I carefully start opening the hole. I do a little,
check to make sure my cut is even around the hole, clean up the plastic and cut again. When I get out closer to
the flat area, I take even smaller cuts. I just try to keep even pressure as I rotate the part into the cutting edge.
It goes pretty quickly and you can be pretty accurate with this. If you look close, you can see the leading fan
hole is done.
Here you can see the finished cuts. When I get to the point where the fan base just barely does not fit, I finish
the opening with a piece of sand paper wrapped around a medium size X-Acto blade. Again, checking to make
sure I sand evenly all the way around. When I am done, the fan base fits perfectly in the hole and snug. I
constantly check the fit as I go.
After the holes are the correct size, I go back with my small chisel blade again and ct the rest of the fan base
down to the fan hatch. As you can see in this photo, non of the bolt heads are touched. All detail is preserved. It
is that way all the way back.
