Tack, right idea (or at least ONE of 'em) but WRONG actuator - do you REALLY wanna wait a full MINUTE for that door to swing open or closed? There are actuators that move anywhere from slower than that, to 'WAY faster - I found some that would move your door full swing in about 5-6 seconds, much faster...

You can get linear actuators that rival hydraulic cylinders (except for SPEED; they're kinda slow, check the specs on that surplus center link)
Just fer chits & giggles I "goggled" bluetooth controller for linear actuator,

Add an arduino board, a bluetooth card, there's probably already a phone app for that stuff, might take awhile...

"Thanks for the info BukitCase. Wouldn't I need a jig or two fences so the work could lay on one fence while cutting the 36" long piece of work?"

Nope - but that wuz when you were still talkin' about a 2-3/4" wide ramp; for that, I would start with maybe 6" or wider...

If you make it out of wood (AND the SIL can be trusted around DANGEROUS tools) it shouldn't be too difficult to set the blade angle 10 degrees off of square and RIP a piece. Rip fence nearly touching the blade (on whichever side of the blade that tilts AWAY from the fence), a couple of sacrificial push...

At last, a pic of the 211 itself; answers the un-answered question of WHICH 211 it is...
My first 211(a) didn't mention flux core in the autoset section of the manual, sold that one to a friend when I found a half-price deal on a MM252/dual running gear/never used 30A spool gun - bit bulky for...
