Love this equipment. Expensive but with a fast payback, (under a month for the full time finish carpenter). Robust construction, bullet-proof design, fast set-ups, comfortable in use, multiplicity of function...
Imported my first unit into Canada in the 80's, (the thinner, shorter model, complete with stand and flip stop), gave it away to a friend when I purchased the longer, wider model in 2000 which is in constant use today.
As a start-from-scratch, Fine Homebuilding "trained" carpenter, that first unit helped me make up for lack of formal training or oversight by an advanced co-worker. Living on a relatively remote west-coast Canadian island, I had to get a boost somehow and investing in the saw-helper, along with that first Hitachi sliding compound was my best career move.
This equipment probably wouldn't jive with a casual carpenter. It's expense and size would be offputting, but for a pro or would-be pro, finisher or framer I can't overplay it's value. With my Makita table saw nestled in it's Rousseu table support and placed conveniently at a right angle to the left wing of the Saw-helper, both hooked to a demand vacume system, I'm ready to rock. My Stabila door level lives safely cradled under the chop-saw strand where about once a day I check the Saw-helper set-up. It's usually deadly, just like I like it.
The double, perfectly flat, always present wings provide the obvious option to cut from left or right, or act as a convenient temporary storage place as I work from left to right, and act as a work bench for sanding, glue-ups, etc. Try that with a roller outfit!
Safety first, Steven
