Namaste Wiley Wood Wittlers. I was looking around recently for a velcro sanding block and was a bit surprised to find that they could set you back as much as $25 a piece and $4 each for the sanding sheets. Now at times I have been accused of being as tight as a frog's bung hole and I'm sure these things are good quality and worth every penny but I like a challenge and set out to see if I could find a cheaper alternative from readily available items. So I set off to the big green shed (Bunnings).
This is what I came back with. 178 mm adhesive velcro conversion kit ($10) and assorted packs of 5 sanding disks ($10 each) from Bunnings.
20 mm thick piece of foam rubber (200 mm x 200 mm) from Clark Rubber ($5).
Stick the velcro pad to the rubber piece. Be careful when sticking the velcro to the foam and work from one edge so you don't get any bubbles under the velcro.
Cut around the velcro pad with a sharp craft knife.
