Those fancy $$$$ Mitresaws? Are usually the first item stolen....company I worked for quit sending them out on a job. Circular saws, worm drive saws, or a handsaw ( usually a "toolbox" one). Some even got fairly good with a sawzall...
If'n ya can't cut a line, ya can just be the Gopher....."Need a box of holes from the trailer, and a Metric Crescent Wrench"
Started out as a roofer when I was a teen. By the late 90s, I was doing stick-builts, foundations, laying hardwood floors, building decks....Most of the houses I helped build were over $300,000, and some were more. Have laid out foundations, for Houses, schools, and factories.....
needed a 100' tape measure once ( at least) to make sure a retaining wall was at right angles to the building ....30'...40' = 50' sort of thing.
Had a bank build, needed windows with a curve top framed....2 sticks of 1 x 6 were provided...I had to bend them to meet the curve needed......LOTS of kerf cuts.....boards were then installed kerf to kerf, and nailed off. Stop in New Breman, OH sometime, and check the north windows out......Bank is on the south end of town, along St Rt 66. Little brick building, can't miss it.
have also done "tilt up" walls.....You pour the floor of a building first. Then form up for walls....laying on the floor....when the layer of concrete, foam and concrete ( with lots of rebars, wire mess, and inserts) has cured long enough, a crane can lift one end, and stand the wall section up....then when it is in it's new home, it is bolted to the iron frame work. usually makes a well insulated wall, 12-16" thick....
As for the plane in question....IF you feel like you NEED such a plane...and intend to USE it..then get it...it's your shop, after all. I just haven't found a need for it, in mine.
