Started working for my dad's water treatment company in my teens, installing and repairing pumps and water treatment systems. Later worked on automated monitoring and control systems for small water treatment systems, including PLC programming, panel design, systems integration, and designing and building our own SCADA software package. Currently employed as a senior software architect at a print software company.

Renovations around my houses have included installing complete bathrooms (both reno and adding new), complete basement gut and reno, and all types of electrical, plumbing, and ethernet/video/audio cabling. Also have a particular interest in home automation -- my current house has several rooms controlled using Insteon gear.

comment Blade comparison, DW4765 vs DW4701:
The description for DW4765 states it's for a tile saw, while DW4701 says it's for a grinder. I'm not sure why those would not be interchangeable however, given that they seem to have the same arbor size and type?

comment How do I verify that a 240v outlet is wired properly?
Or improper conductor size, or mismatch between the current ratings of the receptacle, wiring and/or breaker (eg: 50A breaker on 14AWG wiring with a 30A receptacle). One of the terrible things about electrical is it can "work" (for years, even) while actually being very unsafe.

comment Connection new 4-line phones to an existing multiline network system
Also important: with a key system (or a PBX) you can only use phones that are designed to work with that system. Mixing in regular analog phones (including a multi-line phone that connects directly to PSTN lines) will not work: if connected as an extension, it will probably just malfunction (or worse, damage your PBX); if put in parallel with the KSU/PBX you'll have usability issues including not being able to transfer calls properly, collisions when you pick up lines in-use, and voice mail won't work properly (if your KSU/PBX has that).

comment Can I move my kitchen to the front of the house or any other ideas?
The biggest part of any way you go with this is going to be dealing with the load bearing walls. Do you know which ones are? Is there a basement level below this? What type of foundation? Adding a beam will mean creating new point loads where the beam is supported, and these need to be supported down to the foundation. Remember, the load is the same, but it's going to be supported by two points holding up a beam instead of distributed across the length of the wall. Depending on how things are constructed, you may need to install new footings in the foundation to make this possible.

comment What could be the source of an intermittent, unlocatable rotten egg smell?
You may be having olfactory fatigue and unable to smell it (interesting tip from wikipedia: coffee beans can apparently "reset olfaction" -- which may help you track things down). However, gas is a definite possibility. If I were you, I would call your gas company to get them to come check things out -- they likely have an emergency number for this (free) service. If nothing else, you eliminate one possibility and get to sleep better knowing you're not in imminent mortal danger.

comment Why is half of my house without power with no flipped breakers?
Sounds like perhaps you've lost one leg of the power. Check a 240V stove or dryer plug using your multimeter/tester. Hot-to-hot there should be 240V, and hot-to-ground and hot-to-neutral from both hots should both be 120V. If you have in fact lost one leg, I'd try: flipping the main breaker off and back on, in case it partially tripped. Check with neighbours on the same transformer to see if they have the same problem. Look for any obvious faults in your power hookup (eg, a tree on the power line).
