WOW!!!! That thing is...well...quite large. And that's their "smaller" rotary...I'd hate to see their big rotary (LK603). And yes...there's no way that the 3401's handle will fit on that thing.

Regardless...for the price you got it, it's still worth it. Have fun and enjoy...

The 3403 seems simliar in size to the 3401 (just looking at the pictures on the website)...it's also substantially lighter than all the other polishers they offer. I'm wondering if the LK 302 and 603 are their "older" technology polishers and the 3401 and 3403 are newer releases. I really have no basis for this statement other than pictures presented on their website.

Keep us updated and let us know how it goes.
