It is a great deal. But it's not a router table on steroids, not even close. Speed is the most important difference between a router whether in a table or not, and a shaper.
Shapers typically have 2 speeds 7,000 and 10,000 RPM, both of which are on the LOW end of a variable speed router. Here's the reason..... shaper cutters are usually much larger in diameter than router bits and therefore need to spin at lower speeds to operate safely and efficiently. It's about the peripheral tip speed.
A 1/4" bit can easily spin at 20,000 RPMs but you wouldn't spin a 3" molding cutter at that speed or vice versa. A 1/4 " bit spinning at 7,000 RPM won't operate correctly.
Routers have a brush type motor and are rated differently than an induction type motor typically found on stationary tools. Induction motors are larger, operate for longer periods without overheating and have more torque for a given HP rating....at least that's my experience.
If you get the unit above and want to use it look at Grizzly's 1/2 bore cutters and see what they offer. With any luck you may have a 3/4" spindle and there are more cutters in that size. I have a glue joint bit set up in my small 1/2" bore Craftsman spindle shaper powered by a 1 HP induction motor.
It's just right for that speed and cutter. Foley Belsaw was my source for 1/2" cutters years ago. Let us know what you do!
