What to do if vinyl won’t stick

What to do if vinyl won’t stick

As I write this, I’m installing self-stick vinyl tiles in an old basement as part of a project to modernize a ’70s man cave. It’s possible to run into a few problems when installing vinyl, so I thought I’d run through them, along with the solutions. Here’s what to do if vinyl won’t stick.

Getting vinyl tiles to stick to the floor is mostly a matter of having a clean, dry floor, using the right primer, and using enough heat and pressure. Good prep work and the right tools and technique makes a bigger difference than the cost of the tile.

Using a computer power cord on a garbage disposal

Using a computer power cord on a garbage disposal

When I replace garbage disposals, I prefer to use a power cord rather than hardwire them straight into the wall. The thing is, I don’t like paying $12 for the official power cord, which is chintzy looking and, frankly, looks under spec’ed. Instead, I prefer to use a computer power cord on a garbage disposal.

The label on a 1/3 HP Insinkerator Badger says it’s rated for 5.8 amps at 125 volts. I found a computer power cord in my stash that was rated for 10 amps at 125 volts. It’s overkill, but when it comes to electricity, overkill is good. Best of all, it let me repurpose something I’d already paid for and was probably never going to use.

I got hacked. I did it to teach you a lesson, and I’m sure you believe it.

Yes, you can replace an Insinkerator in a hurry AND on a budget

Dave Farquhar DIY , ,

After having a second Insinkerator garbage disposal in about three months give it up and start leaking, I started wondering if there might be a way to get drop-in replacement at a lower price.

I found it. Actually, I found several.

Need an emergency paint remover? Use baby wipes.

Dave Farquhar Landlording

I don’t remember where I picked this up, but baby wipes are surprisingly effective at removing paint. So if you get paint on some trim or on the floor and you don’t notice right away, reach for the baby wipes–or buy a package of baby wipes.

Paint that’s only a few hours old will come off with little effort. Paint that’s been on a while longer will take more effort.

Tinted primer paint makes painting easier

Tinted primer paint makes painting easier

It took a few years but I discovered a non-obvious way to make painting easier. Use tinted primer paint to cover in fewer coats. If you’re asking if Kilz primer can be painted, the answer is yes. Absolutely.

I’ve painted more than a few rooms in my day, and the majority of them have been difficult to cover shades like red and yellow, or really bright colors. Sometimes when I’m really lucky, they’re the shade of the color that was popular in the 1970s. Those colors haven’t aged well.

Correcting other peoples’ violations of public nuisance laws requires a few steps. The first step is primer. But buy the right one, and don’t use white primer.

Make your own null modem cable

Make your own null modem cable

One of my coworkers needed to make a null modem cable last week, and most of the sites he found made it far, far too difficult. All you really need is 3 wires. Here’s how to make your own null modem cable.

Most of the time, you only need three pins. In fact, I never needed more than three pins, no matter what I was connecting. Usually, a 3-wire null modem cable is more than sufficient.

Use F.lux to help yourself sleep better

Dave Farquhar Uncategorized

I was listening to a podcast when the talk went off on a tangent, to a utility called F.lux. Whoever was talking made it sound like it was just for one platform, so I went looking for an alternative for Windows, given that merely 90.53% of us use it. The answer was F.lux! F.lux is also available for Linux, for what it’s worth. So I downloaded it.

The concept is simple. The lighting on our screens can interfere with our sleep patterns, so F.lux adjusts the screen based on what time it is, so that it interferes less.

When HO is 1:87 scale and when it’s 1:64 scale

When HO is 1:87 scale and when it’s 1:64 scale

I get a lot of questions about the difference between HO scale and 1:64, and it occurred to me that I missed something. I was thinking of model train HO scale, which is 1:87, which is about 25% smaller than 1:64. But for whatever reason, slot car HO scale is 1:64. So here’s how to know when HO is 1:87 scale and when it’s 1:64 scale.

Another reason to block fonts at the proxy

Dave Farquhar security , , , ,

Last week Apple released a bunch of patches up and down its product line. One of the vulnerabilities it fixed in OS X was a vulnerability in its font parser.

In the past you could mitigate vulnerabilities like this by only installing fonts from trusted sources, but since it’s now possible for web pages to transmit fonts along with other content, there’s a limitless number of untrusted fonts out there in the world.

Since it may take a while for all of the major operating systems to shake out all of the problems in their font subsystems, that’s the reason I’ve recommended filtering fonts at the proxy.
