Grabit Damaged Screw Remover

Easily extract stubborn, hard-to-remove screws

This nifty tool has saved my bacon numerous times over the years. We’ve all stripped a screw head before. This simple and elegant gadget fits into your drill just like any other screw bit. One end has a burring tool that burnishes the screw head recess in a few seconds. You then flip it over to the threaded end and engage the damaged screw. Because the drill is running in reverse, it will quickly extract it. The simplicity, low cost and utility of this tool makes it a must-have in my tool chest.

Kreitler Bike Rollers

Ride your bike indoors

Riding a bike on rollers rather than a stationary trainer (on which balancing is not required) is more fun and engaging. It’s much more challenging than riding on a stationary trainer because on rollers you need to keep your balance or else fall, much like riding a bike on the road, albeit a very narrow piece of road.

I’ve used Kreitler rollers for about 6 years. They enable me to ride my bike indoors when it’s raining, or get an intense 20-minute cycling workout when I don’t have time to go for a full ride. They also dramatically improve my balance and control of my bike.
Kreitler rollers are made in the USA and come with a lifetime warranty. They’re the industry standard.

Garageio Garage Door Controller

Control your garage door with your smartphone

I found Garageio on Even though it was something I never knew I needed, I realized that using the old fashioned garage clicker that came with our Genie Model 1024 Pro could be better. Mainly, the biggest drawback of the traditional remote control is that it only works within sight of the garage door. Secondly, keeping the clicker either on the sun visor or in the glove box of the car is a security risk as any thief in the neighborhood could break into the car in our community parking lot (we live in a townhouse in a crowded Northern Virginia suburb) and use it to gain access to our garage and potentially even farther into our home. After using the Garageio for about six months, I thought it was ready for review.

First, a bit about installation: The Garageio allows you to connect up to three separate garage doors. We have a single garage door, so I can only comment on installing it for one door. The Garageio website claims that you can install it in 15 minutes. I’d say that as long as you spend 10 or 15 minutes before you start the installation process and plan where you are going to mount the wires, get familiar with your particular model of garage door opener, and watch the online install video, then that is an accurate claim. Everything we needed to successfully install the Garageio was in the box except the step ladder, the screwdrivers (a Philips and a flathead), and our iPhones. If you are well-organized and are handy, you could probably install this on your own, but my wife and I tackled this together and we had everything installed within 20 minutes. This included having it connected to our wireless network via Wi-Fi and paired with our iPhones. I won’t go into detail on all the steps other than to say that their installation videos are comprehensive, nicely produced, and easy to understand and to follow. Connecting the Garageio unit to your network and pairing your phone is also breeze. We have iPhones, but the Garageio is advertised as working with Androids, too.

Next, a bit about operation: The Garageio does what it is designed to do — it allows you to open and close your garage door via your cell phone app or your web account. The app is simple. It shows a garage door. You swipe your finger up, the garage door opens. You swipe your finger down, the garage door closes. We find it to work pretty reliably, although sometimes it has a synching issue in that sometimes the app might show the door being closed when the door is actually open. This is easily corrected by either swiping the garage door up until it is synched with the actual door or by closing the app and restarting it. If the door is left open, the app will notify you that the garage door is still open. However, it does not allow you to adjust the length of time before it notifies you. This is great for those rare times when you drive away and forget to close the door. Also, their website advertises that you can see who accessed your door and when, but you can only see this through the web portal, not the phone app. I’d like to be able to see these activity reports on my phone, but this is far from being a deal breaker. Finally, you can grant up to ten users access. I’ve never tried to add more people than my wife and myself, but that was easy enough so I assume that adding more would also be easy.

The Garageio has been most useful to us for allowing folks like repairmen and cleaning people to access our home during the day while we are working. We simply have them call us when they arrive and we open the garage door for them allowing them access to the house. When they leave, we ask that they call us again and we close the door.

A new feature of Garageio as of October 2014 is their If This Then That (IFTT) channel. They have some sample recipes you can use such as “If I arrive at my house then open my garage door” and “If my door is opened or closed then send me a text message.” I have yet to try these, but I appreciate that they are developing new ways to extend the usefulness.

Diamond Laser 3000 Xl Bandsaw

Wet saw makes precise cuts

I’ve been making stained glass art for 30+ years, mostly as a hobby, mostly cutting it with the standard manual cutter and grinding it to finish the shape. About five years ago I decided to spring the $450 on this wet band saw and I can’t say enough about how fantastic it is. The blade is so thin that if you are cutting multiple pieces of the same glass, say a sea turtle shell, the pieces come off the saw already fitting perfectly.

It saves me 3/4 of the time it used to take to make a particular suncatcher.

It cuts glass and stone tiles precisely for backsplashes and insets in granite countertops. The blade can raise high enough to cut 1″ thick dalle de verre glass or curved china bowls. You can get wood blades for it too, and my musician husband was able to use it (dry) to make the precise cuts he needed to finish a new bridge for his double bass. It’s a workhorse, and Diamond Tech offers replacement parts if you need them. Five years later my original saw is humming away happily and so is my business.

Oneida Dust Deputy

Vacuums sawdust without clogging the filter

I make boats and do a lot of fine sanding. Wood sanding dust is dangerous to inhale. A good dust mask is a must, but even better is to keep the dust out of the air. For years I just hooked my sander up to a shop vac which helped a lot but the filters plugged up quickly.

The Dust Deputy is a simple plastic cyclone attached to some 5 gallon buckets that is placed in the hose line between your tool and the vacuum. It eliminates practically all the fine dust before it can get to the vacuum and its filter. It saves a lot of time cleaning out the filter and the vacuum maintains good high airflow which allows the dust extraction to work more efficiently. While I still wear a dust mask, I feel it is only due to an abundance of caution.

There are other cyclone systems available, but this compact unit can be screwed to the vacuum and rolls around as a single unit.

Edge Pro Apex knife sharpener

Makes a mirror finish razor sharp edge

I love knives. I own about 20 pocket knives currently of differing brands sizes and styles but the one thing they all share is a mirror finish razor sharp edge. I tried several sharpeners before buying the Edge Pro Apex system (EPA for short) and nothing comes close to the edge I can get from this system.

Where the EPA differs from the other sharpeners I have tried is that it has a blade rest and guided stones, making it almost impossible to ruin your knives. Since I bought the EPA I have become a bit of an edge snob when it comes to my knives. If I dull the blade cutting cardboard at work or ding the edge doing something dumb I am almost excited to run home and sharpen it again.

There isn’t a knife in my house (or family/friends for that matter) not wearing a brilliant edge from this sharpener. The ease of use on the EPA makes knife sharpening a quick and painless affair and I always have a bald spot on my arm from testing knives.

This sharpener is easy to use even for beginners with plenty of videos online with cool tips and tricks to get the best out of this system. My favorite tip is to color the edge of the knife with a marker to help set the angle easily.

I recommend the 4th kit which comes with all the stones and up to a 3000 grit polishing tape because that tape is what really makes the edge fantastic.
