Thread: cheap source of velcro for orbi ?

You can get adhesive backed 1m wide off the roll, cut to length. We used to get it for angel grinder pads when I was metal polishing. A metre length would give us about 40 replacement 125mm pads. Never did find out who we bought it off, think it was an industrial supply place in the Melb Northern suburbs, but a wholesale/retail abrasive supplier would be a good place to start. I think someone mentioned getting some through Sandpaper Man (Forum Sponsor) some time ago so they might be a starting point.


EDIT SM have 300x 500 sheets here

The Velcro is available from the following,

Premium Abrasives Sydney

Abrasiflex Abrasives Sydney

Pferd Australia Sydney (only sell through distributors)

These companys are all on the net and all have warehouses in Sydney.

thanks kindly for the info.

Velcro Sheet - 305 mm x 500 mm | The Sandpaper Man

thanks. That looks like good stuff, but hoping for some that isn't adhesive backed.

just stuff like sold at sewing shops. spotlight etc.

the adhesive I've found doesn't stick well to rubbery surfaces. I want a quick strong adhering processes with 5min epoxy or something like. don't want it unpealing all the time.

Hi Jake, the imprint on the back of the SM stuff appears to be the same as that on the stuff we were buying 7 years ago. It was not an issue of the the stuff peeling off, we were killing the hooks from constant use, allowing the papers to lift from the hook.

It was about a 30minute job to peel the hook disk off the rubber backer, clear the remaining adhesive and get the disk prepped for a new hook sheet. I doubt that the hook sheet would seperate from a properly prepped rubber backer.

We needed a putty knife to slowly seperate the backer from the hook sheet, then gave the angle grinder a touch on the linisher with an old belt kept for the purpose to abrade as much adhesive as possible, which also heated and softened the remaining adhesive, which we then scraped off. Final clean up was a solvent wipe.

With regard to epoxy, it will be hard and brittle, may soften with use due to heating and will be a right b***h to thoroughly clean off for replacement.

Thanks Malb for shariing your experiences with me.

I haven't had any problem with the epoxy attempt I've had in the past in regards to softening etc. But thats not to say I won't in the future.

The problem developed from me wanting to attach a new sheet to the existing pad of a makita orbi which doesn't have an ideal surface to reglue to, to begin with. ie straight onto the existing velcro which is imbedded into the rubber. So I couldn't see the adhesive backed velcro sticking to that well at the time.....to get it done easily at the time anyway.

(can you buy aftermarket attachment pads for makita orbis that don't have velcro on them <- then I'd have a surface to attach to over and over)

...and since the epoxy worked my first attempt anyway, I've figured that all I need do when its time to replace the velcro is run the orbi over a coarse grit on the table to rip off the existing velcro and reglue a fresh sheet. only a few minutes epoxy cure without any cleanup with velcro thats much cheaper than adhesive backed stuff....seemed like the sweetest system (process or whatever you want to call it)

Thats how the idea evolved anyway if that makes sense.

What I want to know though is ......why haven't they designed it for easy replacement of the velcro. To force us to buy a new pad for $30 - $50 bucks ? ....they just wear out too quickly.

And another thing I don't get, is why , especially with a good quality brand like Makita, are velcro hooks so short. They just don't want to grab as much as regular cheap stuff even....just these little short haired pricky things that bruise or burn flat with just a little accident here or there with the grit not attached properly etc.

anyway
Thanks

To clean off the pad, glue a sheet of sandpaper to a board and run the orbital over it without a sanding disc on the base , this will remove the hooks and rough up the surface.

You can glue direct to this with a good contact adhesive, or totally remove the olf Velcro , by using an angle grinder and 40# sanding disc to clean of the remains of the old velcro, finish with a 880#disc and wipe over with metho, then glue on new velcro.

I have used this system , and found that it worked .

For gluing on velcro pads you need Gelgrip. Reason is cos its not sensitive to heat or pressure while remaining flexible.
