Here is my recently acquired Millbury tenoner. Someone else has already posted the eBay pictures of it on the owwm site, but this is what it looks like in my shop.

This machine has obvoiusly sat unused for a long time. All the steel parts were covered with a fine coating of rust. The cope heads have never been used, in fact, the dust hood/ cutterhead guard doesn't have a slot for the cope heads. I suspect the guard was shop made rather than factory made. This machine is old enough to be driven by flat belts. The more modern versions use V-belts. There are no belt guards. At some point, someone did a real half-assed job of trying to paint the machine. They painted everything visible from one side and left the rest. What they did paint is now peeling badly. Unfortunately, I need a working tenoner more than a pretty one, so any rectification of the problem will have to wait.

One feature that the Millbury lacks is the ability to move the tenoning heads together. Most tenoners are set up so that the spacing between the heads for the thickness of the tenon is set first and then the two heads are adjusted together to locate the tenon. The Millbury heads are adjusted independently, which means any change in the setting of one head involves a second change of the other head. Due to backlash in the threads of the adjusting screws, this can be a maddening procedure. To simplify things, I bought a pair of cheap import dial indicators and mounted them so that I could easily measure the settings of the cutterheads.
