Converting an angle grinder into a polisher

[bradleyheathhays]

Is there a conversion spindle that lets a regular angle grinder turn a 7" polishing pad, basically converting it into a polisher? If so, what is the part called and where can I find it?

Thanks.

Re: Converting an angle grinder into a polisher

There are significant differences to how a rotary style buffer and a dual action polisher work.

Converting an angle grinder will not provide the protection benefit of a dual action poisher

• DIGITAL TORQUE MANAGEMENT: Electronically adjusts torque needed to maintain loaded speed level
• Apply pressure directly over the pad, not down toward the base of the tool near the power cord. If you start to come up on the edge of the pad the tool will stop spinning (it will continue to oscillate, however) and you want that spinning action, even if it's slow.
• If the vehicle has curved body panels you will experience areas where you simply can not keep the entire pad flat on the surface. In those cases, roll the tool with the curve of the body panel so as to keep the center line of the pad against the paint, rather than an edge. This way the pad will continue rotate even though it's making less overall contact with the paint.

If the grinder has a 5/8 male connection, technically you can use on of our rotary backing plates. However, you also want to be mindful of the speed range on the grinder. We have seen where the lowest speed is 3000 rpm which is way too fast for working on automotive paint. Max speed should be 1800 & ideally should go as low as 1000 or so. That said, as Old Bear mentioned, there are significant differences between a D/A Polisher aka Random Orbital & a Rotary. It is more difficult to get good results with a rotary & they are more aggressive in general simply due to the action.

I am not aware of any other conversion device if your machine does not have a 5/8 male shaft connection.
