spindle extension for boat detail

[Joe V]

Has anyone ever used a spindle extension with their rotary buffer? I need one to get under a rail on a boat I'm going to buff out (gel coat), but I can't seem to find the one that came with my metabo. So, I made one using an extension nut and threaded rod. I tack welded it together with a TIG weld. It's a little bit longer than the metabo one.

 

 

 

I plan on being careful with "sideways" forces on my pad while buffing w/ the extension so the spindle bearings don't see too high of centerline torque forces. Any other tips out there while using an extension with a rotary?

 

Thanks,

Joe
