Delta 14-600/650/651 Dedicated Mortiser

I'll bet Norm has sold a lot of these and the versions of other manufacturers as well. If you do Mission Style furniture with lots of mortises, you need something like this.

I believe a 14-600 (I had the model # wrong for many years) started it all, however Delta redid it early on, renaming it to 14-650. Then they re-engineered it to the 14-651, which showed up in Episode 1704. I'm part way through reviewing all of the episodes and I'll have definitive identifications eventually. All 14-651 appearances are correct.

Notable distinguishing characteristics are:

• the lack of cooling fins on the motor of the '600.
• the slightly rounded housing on the '600, then the squarish on the '650, followed by the even more rounded housing on the '651.
• no left/right access covers in the housing of the '600.
• the column on the '600 was square tubular steel, the '650 had a plain cast iron column, and the '651 had cross webbed pattern cast iron column.
• the on/off switch on both the '600 and the '650 was a toggle switch while on the '651 it was a push button.
• there is a tool holder at the back of the head on the '651.

Of course it's principally the housing—slightly rounded, quite rounded, or flat—which will be visible in any of the episodes.
