    Hi, I've got a bit of a weird project I'm working on. I'm trying to create a clear hard cover for a keyboard that has holes where someone can still press all of the keys. It would be just a flat piece of material that Velcros onto the top of wireless key board. I've been working with acrylic...

    I have 3 places on the exterior of my house that I will be putting a conduit through. 1 will be 1/2 inch and the other 2 are are going to be 1in. I am running network cable and speaker cable through those locations. This is for home networking, IP Camera install, ceiling speakers and outside...

    Dear DIY experts: I was drilling 1" diameter hole in 4" thick concrete slab using concrete drill bit and Bosch corded hammer drill with SDS chuck. At some point the drill started vibrating strongly and then the drill bit got jammed - the chuck was spinning but the bit was not. After inspection...
  5. Remodeling
    I am trying to run some low voltage conduit for the entertainment center into the near by storage closet. So all things will be hidden. I have a clear pay there and all the little drywall holes cut. My only issue is a second floor support beam. Can I drill a 1.25 inch hole through it? Attached...
  6. Electrical
    I'm working on a plan to do electrical rough-in in a remodel and realized that it would be very convenient to bore a smallish (maybe only 1/2" - 5/8") hole in a set of tripled 2x4s under an LVL beam (thus making them a column, I assume). I've read of course about being able to do a 40% bore on...

    Is it ever OK to drill vertically through a structural beam? I have a 5x8 solid timber structural beam running the span of my basement supported by lally columns. Is there any location on this beam that can support a vertical hole through the beam? I bought the house in January and the...

    Hi there, I just bought a home. I pulled down the existing ceiling in the basement and noticed that someone had drilled 3/4/' holes within the bottom two inches of the floor joists (joists are 12x2). It is for PEX tubing. There are quite a few holes and I'm concerned. I have asked a few...

    For the life of me I can't figure out how to line up something. Not sure a carpenter's level does this, but pushing me in the right direction would be great. Basically, what I'm doing is hanging a 4ft florescent light in the garage. I'm trying to make sure the light will be straight and not...

    Hey, Looking for advice for hanging a heavy sign post on the exterior of our brick store. The sign post is about 20lbs or 10kg and the sign itself if about 42" x 24" solid cedar which is also about 20lbs or 10kg. It will be hanging perpendicular off the wall - so it will be subject to...

    We've had a rash of break-ins where burglars have broken into homes (even with alarm systems) by cutting the phone lines thus disabling the reporting capabilities of the alarm system. I've been told the best thing to do is bury the phone line below grade, drill through the foundation wall and...

    I need to secure a flange to some newly poured sand/topping Quickrete we poured in our basement bathroom. This new slab is just 1 3/4" thick. I'll be securing bolts (and drilling) into the foundation concrete below the sand/topping slab. I have a brand new 19V cordless hammer drill that should...
