0:00 Introduction: Update on RRHQ build, focusing on finalizing the staircase after boiler installation.
0:22 Staircase Adjustments: Addressing a gap left for drywall, deciding on hardwood treads and risers instead of carpet, requiring adjustments to the stringers.
1:10 Stair Height Adjustment: Lowering the staircase by ¾" to accommodate the hardwood treads and ensure consistent step height. Scribing and cutting stringers to achieve the correct height.
2:58 Notch Adjustment: Notching a truss core and adjusting the backside for proper fit after the height adjustment.
6:17 Stair Tread Material: Using LP Legacy subfloor (1 ⅛") for stair treads due to its strength and suitability for gluing and screwing. Hardwood treads will be added later.
13:19 Sturdy Floor Rating: The subfloor material is rated for 48" on-center spacing, exceeding the 16" on-center spacing used in the build.
13:53 SawStop Demonstration: Briefly demonstrating the SawStop safety feature.
17:52 Staircase Construction: Gluing and screwing risers and treads for a rock-solid temporary staircase, to be reskinned later.
23:00 Material Discussion: Justifying the use of OSB for the temporary treads and risers due to its strength and cost-effectiveness compared to 2x material.
27:00 Mezzanine Framing: Beginning to frame the mezzanine level, noting a slight bow in a previously built wall.
27:26 Window Placement: Discussing window placement in the mezzanine, aiming to maximize natural light into the shop.
29:28 Closet and Half Wall Framing: Framing a closet and half wall in the mezzanine, with the half wall providing access for electrical and plumbing runs.
31:12 Framing Technique: Explaining the decision to use horizontal framing members instead of traditional studs for ease of electrical runs and drywall installation. This method also increases wall thickness and reduces usable space.
37:40 Closet Purpose: Considering potential uses for the closet space, such as a recording studio or storage.
38:06 Plumbing Vent: Planning the route for the plumbing vent through a 2x6 wall in the closet area.
38:37 Alcove Plans: Envisioning an alcove area with a large screen and couch, noting the location of the mini-split system for heating and cooling.
47:39 Half Wall Height: Determining the ideal height for the half wall, aiming for 42" for comfort and leaning.
48:46 Drywall Considerations: Addressing potential drywall cracking issues due to extending past the wall plate, but deeming it acceptable in this non-load-bearing situation.
51:53 Vent Pipe Installation: Detailing the process of sealing and installing the vent pipe through the roof using a Silun Pro D caulking gun and Big Stretch sealant.
59:04 Closet Dimensions: Finalizing the closet framing, noting its narrow width but adequate size. Discussing the possibility of a roll-out cabinet.
59:56 Radiant Heat Plans: Discussing plans for radiant heat in the mezzanine, including manifold placement options (under stairs with bookcase or in the closet).
1:01:00 Insulation/Spray Foam: Applying spray foam insulation before continuing with the final section of girt framing.
1:02:47 Wrap-up: Concluding the video, highlighting the completed stairs and mezzanine framing. Future videos will cover electrical work, drywall, and finishes.
