High Temperature Glue Gun

For better bonding to metal, wood, plastic, ceramics, magnets, and other non porous materials

I am in my second year of using the Surebonder high-temperature hot glue gun. As a crafty type, I have used a hot glue gun most of my life, but as a maker, I always opted for epoxy or other stronger, less convenient adhesive options.

There are many high-temp hot glue guns, but I like the Surebonder because it has an attached stand. You can put it down and brush away the glue webs, and hold the piece with both hands. For some reason, it rarely dribbles, unlike most other hot glue guns I have owned. Now I can put two irregular shapes together, tacking first then filleting.

For dirty or rusty pieces that you don’t want to clean (you might like the look of that metal urn, for example, and don’t want a shiny spot), I have found that gluing a tongue depressor or the like down first, then peeling it away, cleans just the glue area and lets you get good adhesion.

The only “drawback” is that it takes longer to harden. But the bond is so much stronger it’s worth blowing a few extra breaths onto the glob to get it to set.

FFF Tour/OverDrive/Exploratorium

Recomendo: issue no. 30

If the Found Footage Festival tour ever comes your way, I highly recommend you check it out. The two guys who host the events scour thrift stores and yard sales for the most obscure and awkward infomercials, public access shows, training tapes and home videos to showcase. I’ve been to four of their shows and I always laugh so hard it hurts. They currently have 8 volumes available on DVD. You can watch videos of some of their findings on the website. — CD

The US is basically the only country in the world not using metric. It’s not that hard to learn a rough sense of how many kilometers in a mile, or pounds in a kilo. But it is very hard to convert temperatures between Centigrade and Fahrenheit. The solution is to convert all your thermometers to Centigrade: on your phone, in or outside of your house, on websites. Have any digital device display only Celsius, so you can’t cheat. In about a year, you’ll have a reliable and native sense of what’s cool and warm in degrees C. This is supremely handy if you travel anywhere outside of the US. — KK

I feel like an idiot for not discovering OverDrive sooner. It’s a free mobile app that lets you check out ebooks, audiobooks, and videos from your local public library. To use it, you need a a library card from your town or county. I got an Los Angeles Library e-card by signing up online and a couple of minutes later I was reading A Burglar’s Guide to the City. — MF

Since I live in the San Francisco metro area, I get a lot of out-of-town visitors. My favorite place to take them is the Exploratorium along the bayside waterfront. It is the original hands-on science museum, and still the world’s best hands-on learning experience. Many of the interactive exhibits now common at science museums around the world began here; the Exploratorium has all of them and many more found nowhere else. This sprawling temple of innovation and maker-goodness can easily occupy me — even after my 50th visit — for four hours or more. (I normally get saturated after only one hour in other museums.) Of course while it is perfect for kids of all ages, every Thursday evening it’s reserved for adults, and crowded with innovators and artists of all types. — KK

I spent the last year buying and returning boots in search of a pair that come close to Lucky Brand Basel boots in comfort and style. I’ve gone through two pairs of them in black in the last 5 years and I finally gave up searching and bought an additional pair in brown. I love these because they’re stylish enough to solicit compliments, and they’re so comfortable that I can literally walk miles in them every day. — CD

Would you like to improve your chance of having an empty middle seat when you fly on Southwest? Here’s a trick I’ve started to use that works. When I board, I look for a 3-seat row of chairs where a very large person is sitting in the window or aisle set. I will sit in that row, either in the aisle seat or window seat. As the plane starts to get full, passengers will be reluctant to sit in the middle seat because the big person is encroaching on the space. One time when I did this, the guy sitting in the seat (he was probably 6’5” and weighed 300 pounds) leaned over and said conspiratorially, “No one will sit here. It’s always the last seat they take.“ — MF

BuildTak Spatula

Remove objects from a 3D printer build surface

I love my BuildTak Spatula, I bought it from them at a 3D printing expo, and it was a great investment of twenty bucks. The spatula is designed to remove prints from a 3D printer build surface. I have a stable of 3D printers in my classroom, and the newest printer is big enough for me to lean inside of.

When 3D printing, prints get literally glued to the glass printer bed, and sometimes it’s a struggle to get them up without damaging the print. Printers generally come with a standard issue putty knife for this. I’ve also used a screwdriver. They are not the right tool for the job. The angle is all wrong. You want to come in at the very bottom of the print, flat to the glass plate, a putty knife needs to be flexed strongly to get it in that position. The spatula on the other hand has a head that is at a right angle to the handle so it easily slides along the plate; this means that the you don’t have to flex the blade. The large flat blade makes it less likely to damage a print, and allows for easier use on large prints. The handle is nice and comfortable and allows for quite a bit of force to be applied.

I also use the spatula for cleaning the glue off the bed. I wet the surface and can glide the blade along the bed picking up the left over glue.

Six-Ounce Pyrex Custard Cups

Glass cups safe in freezer and microwave

Glass custard cups do not seem like a cool tool you would use all the time, but once you have them I bet you will. A lot of the Pyrex custard cups I own were hand-me-downs or bought at the flea market. They can be microwaved, placed in the oven (even when taken frozen from the freezer), and do all the things you would expect from good Pyrex products. I use them almost daily, as dipping bowls, to hold condiments, receptacles for hot items like bacon grease, small containers to put in the refrigerator for leftovers with a little plastic wrap on top. Glass is very easy to clean and does not stain or retain odors.

What’s in My Bag? — Marcel Dufresne

A couple’s gadget bag for traveling

These are the contents of my gadget bag when my wife and I go traveling. The contents vary somewhat depending on whether we are camping or traveling outside of North America. All the items in the photo I would consider an essential part of our time away from home.

The bag:

Prop ’n Go Tote ($50)
This bag has enough room to hold all the items (most of them are flat and take up little space). The bag has some padding to keep the contents somewhat protected. There is a small pouch at the top that keeps all the cables and then GNS 2000 (below). Best of all, it allows me to position the iPad at whatever angle I need for comfortable use while reclining.

What’s inside the bag:

iPad (Varies)
The iPad is the most important item for me. There are too many uses to list here. I use an old case with it to protect the front glass while in transit.

Amazon Fire
Fire Tablet ($40)
The Amazon Fire is my wife’s ebook reader, as well as email and surfing tool. She needs her own as I am usually using the iPad and not willing to share.

HooToo TripMate Elite Wireless Router ($30)
The HooToo Elite serves many functions. It is a charging plug and a spare battery pack. I store movies on my thumb drive and use the Elite to wirelessly connect it to my iPad (no internet needed). Lastly, it is a Wi-Fi booster. The thumb drive I carry is an F80 32G drive from Silicon Power ($19). It is lightweight but very sturdy, being totally metal. There are no caps to worry about and it is supposedly water resistant (have not tried this out). These two items sit in the convenient storage case that comes with the Elite.

3-1 charging cable
3 in 1 charging cable ($7)
The 3 in 1 charging cable cuts down on the number of cables I carry. I can use it to charge the iPad, the Fire and my bluetooth speaker.

GNS 2000 GPS ($85)
The GNS 2000 is my offline GPS system. It connects via bluetooth to my iPad (which does not have GPS capabilities) and serves to get us around. It enables any map app on my iPad to show our immediate location.

Skross World Travel Adapter ($40)
The Skross world travel plug is an absolute necessity if travelling abroad. It also has a couple of USB charging slots.

tuneFRĒQS Share headphones ($30)
The tuneFRĒQS Share headphone cable can by used separately or with my wife’s headphones plugged into it. We can listen to podcasts together at the airport. It also has an on/off button to quickly control the broadcast.

Now for some less used items:

Blue Piston
Logiix Blue Piston Element Speaker ($50)
This bluetooth speaker has my whole music library stored via a micro SSD card. It is water resistant and perfect to carry along. It also serves as an iPad speaker when needed.

Solar Power Lantern
Solar lantern ($17)
A solar lantern is a great flashlight to carry along. I don’t have to worry about batteries for it. I use it to read from late at night when I don’t want to disturb my wife. The placement of lights in hotel rooms is not always suitable.

electroc teacup heater
Portable immersion heater (varies)
Lastly, there is an electric teacup heater. It will heat up a cup of water in no time at all. I picked this item up at a small hardware store in South America.

CargoRAXX – unrecommended

This appears to be a shill review. Many thanks to Cool Tools reader Matthew Connor for looking into this. He wrote:

Meaghan Hollywood works for CargoRAXX. Meaghan Hollywood put a review up quasi-anonymously on Amazon. A similarly worded review is now anonymously on KK.org.

On Amazon there are two reviews for the product (https://www.amazon.com/CargoRAXX-S1A-Interior-Management-System/dp/B01A6X4MBS). Neither is attributed by name but the one from January 18th, 2016 refers to “my Tahoe” and read similar to the KK.org review. Let us suppose the author is, in fact, the same person.

Clicking on the name for the review – merely “Amazon Customer” brings up their profile (https://www.amazon.com/gp/pdp/profile/A1CF94IIWSAE00/ref=cm_cr_dp_pdp). This profile contains one Wish List on the left side. Clicking on it revels – the name of “Amazon Customer” – it is Meaghan Hollywood.

Ok. I believe at this point the author of the KK review and the author of at least one of the two reviews on Amazon are in fact the same person and that person’s name is Meaghan Hollywood.

Here’s the kicker, CargoRAXX has a website with a blog feature – their blogger’s name is Meaghan Hollywood. (http://cargoraxx.com/5-reasons-re-organize-suv/)
