backing plate margin?

[wonderd]

How much margin do you guys usually allow yourselves with the pads and backing plates? For a 7 inch pad would you use a 6 inch or 6.5 inch backing plate?

How much margin do you guys usually allow yourselves with the pads and backing plates? For a 7 inch pad would you use a 6 inch or 6.5 inch backing plate?Depends on the backing on the pad. If it goes to the edge of the pad you could use a 6.5" bp. If it doesn't, use a 6" bp. Also physically measure the diameter as some backing plates are smaller.

Here's an article I wrote that also shows you an idea of what the safety margin for a backing plate is to a foam pad.
