Excellent advice from ConCretin. In the PNW the terminology is: float and smooth trowel. What you don’t want is a “hard trowel”, hard trowel will get a shiny slick surface.
It’s not a frost issue, it’s expansive clay soils. You either need to dig down to below the clay, use piers, or pour some sort of structural floating slab.
Those are two different welds, should have separate call outs IMO. Top is a filet, bottom would be a flare bevel. Not sure the .197 is large enough for a 3/16” weld though. Weird the designer doesn’t know the proper call out.
Wow, this thread brought back some memories! I had a Maccano set, my favorite build was the crane with a bent roof panel. I remember the little wrenches and bent handles screwdriver.
My Milwaukee slow 3/8” with 55 ft lb rating would give a bit a jerk when it ran fastener tight, the high speed @ 35 ft lbs is easier on the hand. Both can be used as a manual tool to lossen or tighten fasteners. Neither are as fast or as torquey as my old air ratchets though, but work well.
I have both the 3/8” high speed and slower higher torque model. I love the high speed. Can it break head bolts loose - no. But as a nut runner it’s great.
Magnifying lens for your helmet, they’re awesome for old blind welders. You can get them in different powers. I have some from Miller, but I’m sure other companies make them. Game changer.
Depends what type of soil you have, if it’s good fill material then yes. You’ll probably need to cut at least a foot or more off all the site to get past the organic material.
