Default DIY sanding drum sleeves

I've finally burned through the last of the sleeves that came with my 1-1/2 inch sanding drum. So off I go to the home centre to try and get some new ones. I know they don't carry them in stock so I'll have to talk to the staff and get them to order me some. I toss a used one in my pocket to aid in the ordering process. Here's a rough transcript of the ensuing dialog:

Me: I'd like to order some of these, please. *hands over old sleeve*
Store Staff: *takes sleeve and examines it* What's this?
M: It's for my drill press.
S: *blink, blink* Eh?
M: Yeah, goes around a rubber drum, and the drum goes in the chuck of the press.
S: *blink, blink* ...
M: *sigh* Yeah, and you sand stuff, you know, like this... *resorts to body language*
S: Oh, sand paper? *tries to switch to English* Sando paypa?
M: Yes, yes! That's right.
S: ... ... ...
M: Erm. Ok. Hold on a second. *runs to the Dremmel section, grabs a pack of small 1/2 inch sanding drums and sleeves made for a small rotary tool, returns to the service desk* Like these, only bigger.
S: Oh, I see. Umm, who's the maker?
M: Don't know. But doesn't matter. Just need 1.5 inch ones.
S: Ahhh, inch? It's from overseas? .... Mmmmmm.... Inch.... Inch....
M: Well I could probably make 4 cm sleeves work if you don't have them in inches. My drum expands a fair bit when you tighten the screw so 4cm should be ok.
S: I don't know. That might be dangerous. What's the maker again?
M: I don't know. It doesn't matter. I just want something like this.
S: ... ...
M: Ok. Look, try this maker. *holds up pack of Dremmel drum sleeves*
S: Ok. We'll call and see if they make them. *starts filling out forms and taking my information*
M: Ok. I'd like a few, please.
S: The guy in charge won't be in until 1 o'clock. Do you want to wait or should we call you?
M: I'll wait. I'll be wandering around in the sand paper section.
S: Ok. We'll page you.

By now I know that my quest is futile, so I begin gathering supplies for making my own sleeves. They page me and I spend another five minutes explaining everything a second time to the guy who came in at 1 o'clock.

S: Can you wait while I call them?
M: Sure. I'll be in the sand paper section.

10 minutes later guy comes running back.

S: Sorry, they don't make them.
M: Ok. Thanks. *thinks but doesn't say, "And they're the only maker of this kind of thing in the country, right? Whatever. I'm outa here"*

Already had my basket full of what I needed to make my own so went off to the checkout with no hard feelings. I'm used to it by now.

Turned out to be a really easy build once I found out that the inside of a toilet paper roll cardboard tube is exactly the perfect size for a 1.5 inch drum. Some cloth-backed sandpaper off a roll, some Titebond II, and a buttload of paper clips... and presto!

Completed one whole project with it already and it seems to be holding up amazingly well.

Will make more and keep you posted. Just gotta remind my family not to chuck the TP tubes when the roll is finished.

Yep, sounds about right. Now make twenty.

Harbor Freight Tools sells those entire kits but not the replacement sleeves by themselves. It's crazy.

Hahaha, such a well prepared salesman! :-))

Anyway, I use the dremel rubber drum with it's small sleeves, and I never bought sandpaper drums, I use thick paper rolled on some thin pvc electrical tubing for the base, titebond wood glue between the paper and the sandpaper. It woorks perfect, and it costs 10% of the original sanding drums.

Yeah, I think that's the key: the electrical tubing. A while back I tried making my own drums out of wooden doweling and bolts drilled through. Just glued the cloth-backed paper right on the wood with Titebond.

It didn't work so well. The wood was too hard I think and caused the piece to bump and bounce against the drum... which then, in turn (pardon the pun), made me, I guess, push harder, which then caused the paper to fail. This was only about half-way through one project.

Notice the cloth backing is still stuck on the wood (Titebond II rocks!). The paper failed between the sand coating and the cloth, not the cloth and the wood.

Although I think the problem was caused by the wood drum being too hard, it's not entirely impossible that the drilled hole through the drum wasn't perfectly centred. This could have been a contributing factor.

I've got some plans to experiment with velcro covered wooden drums and fuzzy backed strips. The idea is that the velcro would be softer and have a cushioning effect. The grit could be easily replaced, like on my disk sander (which I converted to velcro last year and is still working very well). Don't know if it'll work. Might be tough to get the edges flush enough not to snag on the piece you're sanding. We'll see.

Hahahaha! Love the dialog! I can relate to every bit since I have very similar responses with the stores here! Welcome to Asia people!

Great stuff Jeb! It's always interesting to see how we can find ways around blocked roads!

That's a great tip Jeb. That looks to work as good as the ones you buy maybe better and probably cheaper once you get the process down.

You can also use the finer grits if you want...instead of being limited by what is sold.

Yep, so far, at least as good. And waaaay cheaper. The rolls of sanding cloth are 3 inches wide so I can get two sleeves across the width of the cloth with no waste at all.

However, I found out today that it appears the toilet paper companies have yet to standardise the diametre of their industry's cardboard tubes:

Hmph. The things you learn.
