Sanding discs on the lathe, do you glue them on or use something like velcro?

[justinpeer]

Just spent a while cleaning old sandpaper off a sanding disk for the new-to-me lathe. Looks like it had been glued on with regular wood glue and took a long soak and judicious use of a chisel to clean all the paper and glue off. I've given it a clean with a wire brush and some fine emery and it looks like new.

However, what's the best way to attach new paper to it that allows you to change the paper/grit more easily in future as I'd want to be ale to go through a series of grits when sanding?

I've found self adhesive disks at Axminster which says they're re-usable if you heat them with a hot air gun to soften the adhesive before removal. I thought perhaps of using velcro in a similar way to the pads on a random orbit sander but haven't found anything suitable for an 8" disk.

Just wondering what folks here use for such a thing.

I sometime use Spraymount or similar, easy to peal off.

lots of velcro or hook/loop options available. Useful because you can change grits easily

Velcro is far easier and the discs seem to last forever. You will have to source the hook disc first of course. I see them on US websites.

150mm and 300mm Velcro pads and discs available from Charnwood at modest prices:

Search on VB300 for the 300mm pads

Thanks every one for such helpful answers. Looking at the velcro that Charnwood sell, it looks like regular self adhesive backed hook velcro and I've remembered I have some of that in the workshop. Only 2" wide but a few strips of that should cover a 20cm disk and then I just have to buy some velcro backed sanding pads. Should have that all sorted soon. Thanks again.

As an aside, I find sanding with a velcro backing can unintentionally soften edges that you might want to keep crisp. I don't get that with glued on sanding disk.

Rather than sanding disk changing, I have several homemade mdf disks with screw mounts for the lathe, with different grits attached. It's faster to swap the entire disk rather than remove velcroed sanding sheets, after a short time either the backing sheet or on mdf disk velcro loses grip. Don't have that problem with separate mdf disks. Also great for adhesive sanding disks.

I am fortunate to have picked up a second hand m33x3.5 tap, so easy and cheap to make my own mounts from hardwood offcuts.
Daresay that buying 8 or more steel faceplate or face rings would be very expensive.
