A special message from Arbortech CEO and Tools Inventor, Kevin Inkster.
To allow you to continue using the discs or to allow the use of non adhesive cloth backed discs, we have come up with the following solution.
The only real difference is a longer countersunk screw and a plastic flange which replaces the hex head screw in the pad. When or if you have the problem of discs coming off, it is a simple matter to stick the disc to the rubber pad (with the screw and flange removed) then push the screw and flange through the paper to the screw it to the extension shaft. The screw and flange are glued together and will screw in easily when you rotate the rubber pad. You only need hand tightness so no tools are necessary.
One of the benefits is that you can now use virtually any 50mm discs with or without adhesive including cloth backed discs which seem to last a very long time. You may need to punch a hole or cut a small cross in the center of cloth discs but we have stocks with a hole already punched.
So if any of you are having the problem or even if you’d just like to get hold of the new screw and flange, contact Yen here or email to email@example.com with your postal address and we’ll send it out to you.
