We're going to sand floorboards now, and we're
going to use this large drum sander which does the center part of the room. And then we'll use the small edging sander
to get around right to the perimeters of the skirting board, and we finish off right into
the corners with the small detail sander. We definitely need ear muffs and we definitely
a dusk mask. Before we start using our machine we must
make sure all our nails are firmly embedded into the wood below the surface. About two mil should be sufficient to drive
a nail down into the wood but we must be careful that all the nails are gone, otherwise we'll
rip the belt. Now we're going to put a belt on the sander
and start the work. Now my preference to make it easy is to tip
the machine on its side like so, open the front like so, and for this floor, because
it's in quite good condition, we'll start with a 60 grit rather than using a 40 which
a very, very coarse, and all we have to do now is simply slide it onto the drum.
Now that's fairly firm as I've put it on,
and if you have any trouble with it, it's a good idea, just a little bit of sawdust
smeared on the inside of the belt will make it much easier. Now when we start sanding we want to keep
going with the grain. We don't want to go across because we're going
to make a lot of scratches, so we want to move and down but always travel the machine
forward, don't pull it backwards.
Always move forward with the machine. So to get to the other side, turn around and
come back. Now, one important thing before we start is
to make sure you move with an even motion. If you stop the machine, because it's spinning
so quickly, it'll start to dig a trench in that area so you must have an even flow right
throughout the operation. Once we've turned the motor on, the motor
is spinning, but we need to drop the drum down onto the surface and then proceed, and
as we go across like that, when we get near the other side, pull the drum back up so we
can turn it without scouring or scratching the floor. This is the edging sander to get in all around
the skirting boards. This one runs in a circle, unfortunately you
have to cross the grain, you've got to try and cover the area, but the idea is you don't
use too coarse a grit so you don't leave deep scratches in the wood.
Now using the edger we can now get into all
the areas except the very tight corners where we can't reach with the larger drum sander,
so it enables us to finish the job into wardrobes and things like that. So just simply take the oldest off, you've
got a lock, nut and washer, and replace with the next disc.
Using these you'll need your same dust mask
and ear muffs because they're just as noisy almost as the bigger machine. Now, with this one, you can already see in
the corner here, we can't reach the very edge, so therefore, we use our little detail sander
to tidy up those, but the rest of the area we can work around quite successfully. These are very easy, we just simply select
the appropriate paper and grit that we need, and they just simply Velcro onto the base
and we're in business.
It's come up really nicely. It's good timber. Hot, dusty work but that's it, we're done..
