While I generally prefer hook and loop backed sanding disks for their quick change convenience as I work through the grits, there are times when PSA disks are preferable. One of these cases is when power sanding bowls on the lathe using small disks. Depending on the shape of the vessel being sanded, it can be quite strenuous, with a lot of heat being generated with both the work and the pad spinning. Cloth backed disks are my choice for tasks like this since they tend to be more durable than paper backed and are less prone to being torn off when engaging the work at an odd angle.
The issue with PSA of course, is that the disks are pretty impossible to re-use. You can buy multiple mandrels and keep each outfitted with a different grit, but even then, you need to chuck and un-chuck each mandrel as you switch pads. It would be a real time saver if you could use a quick change hex shank system like with driver bits. Well, you can!
I found several videos online from various people on YouTube describing ways to turn your own mandrels using longer hex shank bits. The lathe allows for making the body for whatever size pad you want to use, (we sell 1", 2" and 3" PSA disks) and even center drill the hole for inserting the hex shank. When combined with a quick change holder, your drill-driver can be used for power sanding and you can change from one grit to another nearly instantly.
I love YouTube for all the information there as well as the inspiration! These videos have given me some ideas for other turned pad holders. I feel a video series coming on, stay tuned!
