Where to find it?
Celebrating Craftsmanship: Soldering Basics
To solder, Richard explains that you need solder, flux, a blowtorch, a pipe cutter, and a pipe cleaning tool. Depending on the location of the work, protective items, such as a spray bottle of water or a flame shield, may also be needed. All of these items can be found at home centers and plumbing supply houses.

Changing a Two-Prong Outlet to Three
A room will have to be rewired if there isn’t a ground present. However, if you want to have a grounded, three-prong receptacle without rewiring, you can also use a ground fault circuit interrupter (GFCI) found at any home center.

How to Build a Deck Railing
Nathan built the deck stair railing out of fir decking in a variety of sizes, including 2x4”s for the top and bottom rails, 4x4”s for the posts, and 2x2”s for the balusters.

To cut the lumber to size, Nathan used a sliding compound miter saw, which is manufactured by Dewalt [https://amzn.to/3B9AP4g].

Expert assistance with this segment was provided by William C. Gilbert Carpentry.

How to Paint Outdoor Railings
Mauro wanted to match the paint color of the existing deck, which he did by bringing a small sample of the existing paint to a local paint store. Most paint stores and home centers have machines that can scan a sample and generate a close color match to the paint.

The paint Mauro used for the railings was Behr Premium Plus Exterior Semi-Gloss paint and primer (https://www.behr.com/consumer), though he also used a separate, oil-based primer for the base coat.
