If you heat with electricity and live in a warm and sunny climate, consider installing a solar water heater. The solar units are environmentally friendly and can now be installed on your roof to blend with the architecture of your house.
When not in use, keep your work ladders locked up so that burglars cannot use them to break into your house through the upper floors.
Glue will soak more into the end grain of wood and potentially result in starved glue joints. To help prevent this, you can “size” any end grain to be glued with a mixture of glue diluted with water. Dilute just so that when it is applied, glue drops don’t form at the lower edges of the wood. Another method, somewhat less effective, is to coat the end grain with full strength glue, allow it to dry 5 to 10 minutes, then re-coat with glue and assemble.
The problem: you don't have a mortar box or wheel-barrow to mix up those small batches of concrete. Instead, use the ring method on a slab or sheet of plywood. Put down coarse aggregate on the bottom, followed by layers of sand and cement. Reserve the center for a mixing well. Then add water to the center and pull the ingredients into it with a garden hoe.
