In this video i'm going to walk you step-by-step through replacing the
sandpaper on this big beauty the G0449 and its big brother the G0450 drum sanders.
For this operation you'll need a Phillips head screwdriver with at least four inches
in front of the grip, a tensioning tool that was actually included with the sander
looks like this, and a roll or two of six-inch-wide sandpaper in your desired grits.
You'll also need a straightedge and a knife to cut the sandpaper. Also handy for installation
is a small hammer and a flathead screwdriver for helping to remove these sandpaper clips later on.
Before we jump into the actual steps, let's take a look at the drum sander itself
and the components that are moving around so you have a better idea what's happening inside.
There's the main drum itself, both front and rear,
and then on the ends you have an assembly called the tensioning wheels.
Tensioning wheels grip the sandpaper on both ends, and, as the name suggests, they apply
spring-loaded tension to the paper to keep it from popping off while rotating at high speeds.
So ,these two elements are separate but they do connect together here in a bit when we're changing
the paper by inserting that spring-tension tool that I showed earlier, but more on that in a bit.
The paper itself is clipped into place using these clips keep in mind that there is no need to
drive the clip over the sandpaper, but rather just simply apply the clip too
much force could potentially break the clip, so just a little bit of tap with a hammer.
With the basic anatomy out of the way, let's jump into the installation. First things first,
let's remove the machine from power, and in that case it means shutting it off at the breaker.
Lift the top cover and place the spring-tension tool like this.
I'm inserting it now to allow the drum to fully-rotate around,
that way when I insert the screwdriver through the access hole in the right side of the frame,
and then i can insert it into the drum, you rotate the sanding drum toward you to de-tension the
sandpaper and align the spring-tensioning tool with the hole that's in the drum.
Press it in place and the tensioning wheel should stay-put. You can now remove the screwdriver.
Next, remove the sandpaper retaining clips
and unwind the old sandpaper–this is where that little slot screwdriver comes in handy.
This is a great chance to use the sandpaper as a pattern for the next piece. Now,
if your sandpaper is damaged or you're switching to a different width sandpaper, or you just enjoy
doing a little fun math, you can always use this diagram to help you figure out your hypotenuse.
The hypotenuse is a fancy way of saying the length of the angle that you'll need to
cut into the paper. Simply use a soft tape measure to get the drum circumference
then transfer that number to the paper to figure out your taper angle
Cut that mark and then lets head back over to the left side of the drum.
Fold the sandpaper, like this, and insert it into the clip,
then seat the clip into the tension wheel. You can lightly-tap the clip with a hammer, if needed,
just be sure not to hit it too hard or you'll risk damaging the clip.
Tightly spiral the paper around the drum, ensuring there are no bubbles or
overlapping edges on the right hand side fold the corner of the loose end
into the remaining clip and install the clip on the right side tension wheel.
Remove the spring-tension tool and the drum and tensioner will apply proper pressure
and you're good to go.
If needed, you can repeat these steps on the remaining drum
with a different grit option. Make sure that you've collected all your tools,
close-up the hood and reconnect the machine to power and you're ready to start sanding.
