Hello I found a 1/4x20 fine thread bolt and a 5/16-24 fine thread flange nut and welded them together to make a “Nut Head Bolt” then screwed them together with lock washers! Works great! Now this old polisher is compatible with the old and new polishing pad kits!! See video https://m.youtube.com/shorts/uQoLZrkCx6U Pic 1 - Air Polisher - 1/4x20 Bolt - 5/16-24 Nut - Polishing Pad Pic 2 - 1/4x20 fine thread Bolt - 5/16-24 fine thread Flange Nut Pic 3 - Welding the top of the nut to the head of the bolt.

Pic 7&8 - New polishing Pad Kit part # 58187 which is the same Part # as the old kit with the pads that fit the polisher! Pic 9 - Old polishing pad kit
The Saga continues…. I actually found the old Harbor Freight buffing kit. Same part # 58187 and it has one piece with the 1/4-20 fine thread (M6-1.0) and Velcro which will attach to the new buffing kit. If that piece is not availabke Then welding a Nut-Head-Bolt will work as outlined above. Does anyone have a newer air polisher with the 5/16-24 Shaft or hole for the new buffing kit?

Side note: The pad attachments above will work with the Home Depot Ryobi Buffing kit too. I use the applicator pad on the HF Air polisher and the Ryobi buffing pad on the drill to stop the old switcher-ru routine!
