What is this plane attachment?

[Doug Hobkirk]

I'm curious - one of you might even want it.
Millers Falls No. 8818 Dyno-mite plane attachment (http://cgi.ebay.com/Millers-Falls-Dyno-Mite-Plane-1955-Attachment-Nice-No-R_W0QQitemZ160230303925QQihZ006QQcategoryZ4123QQss PageNameZWDVWQQrdZ1QQcmdZViewItem)

I was thinking that it looked like you shove an electric hand drill in the hole with some Miller's falls cutter on it to make the hand drill into a plane but there seems to be no place for the cutter to contact the work when I look in the pix of the bore.

Remember when those multi tools were all the rage~? Every one bought 'em and none of them ever worked. It was like wishful thinking in a box.

Judging by the third picture (showing a guard) and the second picture (look like a bearing) I would assume that this plane had a motor or drive (cable?) attached to rotate the blade. The slant fence would have the same application as on a normal jointer.

[Charlie Mastro]

That would be for planing the bevel on the edge of a door but it's useless without the router to go in it.:(

Look at the other Millers Falls Dyno-Mite listings on eBay and it will be clear.

They sold a drill motor with all kinds of attachments.

Surely, there was one person who bought one of these and liked it.
