Hi, this is Pat Hawley. And this is the
drum sander that I made just for thicknessing guitar sides and backs.
Pretty simple machine. It's got a motor on the bottom.
And it goes up and is attached to the belt
to a pulley that's connected to a drum
that has sandpaper wrapped around it.
The sandpaper's just on with a hook and loop system.
It's pretty good.
And the table here can go up and down.
Let's see here. I can do fine control with this
screw here, that goes up and pushes on the bottom of the table.
So, this turns on and it rotates the drum.
And I push the wood through underneath that
and that's how I thickness it.
So...
That's the idea. But I have to... You can imagine the dust that it kicks up.
So, I made this hood for it.
It fits on top of here.
And it's got this little opening here which fits the hose
from my shop vac.
So, when I'm working this I have the shop vac turned on.
And sucking up all the dust that's being made by the wood that I'm thicknessing
as I'm pushing it through.
Move it up a full thing but parts stuck.
That's as good a place to start.
I call that corner turn.
That's one. Three different grades of sandpaper.
250,80 and 120. Careful though.
Sixty I use for my initial thicknessing.
And I find, when I get to the last millimeter or so
I switch to 80 and then the last half millimeter I switch to 120.
As far as I can shut that off.
Yeah, you supposedly take this as a tool for initial thicknessing
Like for changing... For changing...
Oh yeah, that works pretty good.
It's supposed to be 80 grade on there now.
Needs to be cleaned up.
Normally when I change the paper
So, this here is all Velcro. Yeah.
And I guess they got Yeah.
I thought of some convenient way of putting the paper on and off.
Felt makes it a little bit softer.
Another issue I just worked on.
Before I went to this system I just had wood there.
I hoped using sandpaper would hold on with 2-way tape.
And I actually found, between the hard table and the hard drum Uh huh.
It was pretty rough on the wood. Uh huh. I think that probably
the commercial ones that you buy where you have like the bed.
And I think there's a little bit of give in the bed. Uh huh.
I don't know, really but I'm supposing.
Anyway, I found that once I went to this hook and loop
system, like ie the Velcro.
It was a lot better on the wood.
So... This is the 80 grit.
This is bad here. I really shouldn't be using this.
They come in rolls. That's how you catch wood. Yeah.
Anyway, so it makes it pretty simple.
So, do you need to somehow smooth it down or is that it?
It's pretty good the way it is. Wow, that's quick. Yeah.
So, I definitely recommend that.
