It will take longer for the majority of cuts you will most likely be making as a jig saw is less aggressive in cutting action.
I thought circular saw would be better at long straight cuts. Reason I asked was because I watched a how-to DVD, and they (supposely pros) were using a heavy duty miter saw for width cuts and jig saw for length cuts. I'm sure they have no shortage of tools, so I wonder why they didn't use a circular or even table saw for the long cuts.
Circular saw is new to me, never operated one before. I guess from a safety point of view I'd better stick with a jig saw (and perhaps an entry level table saw).
Grinding the metal door jamb will be the tricky part, I have to think about that. The gap filler idea was from a guide I read on the net, attached is the relevant page from that guide (pdf inside the zip file). Maybe I should just hire an installer (that will easily double the cost), but then laminate is meant to be DIY, correct?
