OIML-M1 Scale Calibration

Back in 2017 one of the ladies at Red Blossom Tea chastised me for not using a tea scale. I went home and ordered an American Weigh Scales SC-2kg, which measures up to 2kg with 0.1g resolution. It seemed adequate for the task, and compact enough that I wouldn’t mind it taking up a little room in a drawer if I ended up not using it frequently.

At the start of 2020 I decided to become an adult and begin to measure all solid kitchen ingredients by weight instead of volume, so the SC-2kg began to see much more frequent use.

That went along swimmingly for about a year, until the beginning of 2021 when I became curious about the accuracy of the scale. Nothing in particular prompted this curiosity. I just enjoy knowing that the tools in my life are both precise and accurate. As helpfully explained by LabBalances, there are a number of different scale calibration systems in the world. All of it is overkill for use in my personal kitchen, but I decided to look into the OIML-M1 class from the International Organization of Legal Metrology.

The calibration procedure for the SC-2kg requires 1kg and 2kg weights. I found a good deal on a set of 2kg, 1kg, 20g and 10g OIML-M1 certified weights on eBay. According to OIML-M1, a 1kg calibration weight must be accurate within 50mg. A 2kg calibration weight must be within 100mg. That’d get me a pretty accurate bowl of rice.

When I received the weights I found that the SC-2kg reported the correct measurement for all 4 calibration weights. I also tried the calibration weights on my MyWeigh UltraShip Ultra-35, which is the scale I’ve had kicking around since 2009 for measuring backpacking gear. It only claims to have 2g resolution up to 1kg, and 5g resolution up to 16 kilograms. I found it to be accurate within its claimed resolution.

So all of this was for naught. Both of my scales were already accurate and not in need of calibration. But I really enjoy having these OIML calibration weights and knowing that my measurements conform to the standards of the universe.

Velcro cable ties are useful.

But I’ve become quite smitten with Ringke Silicon Cable Ties. Unlike hook and loop, they don’t stick to things that you don’t want them to stick to. Most importantly, they are easy to open and close while wearing full-fingered gloves. This makes them great for cables you carry around while out and about in meatspace, such as earbuds and power cables. I’ve only been using them since July, so I can’t speak to durability, but I see no reason they should not satisfy in that department.

For thicker cables that need to be restrained with a bit more vigor, I am fond of the new Voile Nano Straps.

Titanium Fuel Transport

Last January I bought a pack of generic stretch silicone lids. My hope was that one of the sizes in the pack would fit my 16 year old Snow Peak Trek 700. One did. This turns the mug into an excellent fuel transport container. It’s kind of a poor man’s Vargo BOT 700.

I have filled the mug with water, installed the silicone lid, flipped it upside down, and left it standing overnight. In the morning there were no leaks. I’m still hesitant to actually transport liquids using the lid. Mostly because the silicone is extremely thin, and I’m sure it is going to tear eventually. But if you’re into cold soaking food on the trail, and don’t want to carry a dedicated jar, I think this could be an attractive option. For leftovers, it’s perfect.

The lids I bought are no longer available, but there is certainly no shortage of equivalents floating around on Amazon-AliExpress-eBay. Based on the number search results, my impression is that China is drowning in silicone stretch lids.

Optical Support Kit

I use an Ultralite Sacks Trail Wallet to carry a few items that support my Rudy Project Rydon eyewear. I have six or eight of these simple cuben fiber zippered pouches floating around for different uses, either from Ultralite Sacks or Zpacks.

I’ve previously mentioned my infatuation with the ImpactX2 Photochromic Laser Red lenses. These remain my lense of choice 99% of the time. But sometimes I want a polarized lens (such as when on water), or one with lower light transmission (such as when the sun is low during the equinox), or one with higher contrast (such as when on snow), or one that is not photochromic (such as when in an enclosed vehicle for an extended period of time). All of these conditions are satisfied by the Polar3FX brown lenses. I carry these in the wallet inside of the small microfiber lens pouch that Rudy provides.

A microfiber bag is useful when I want to put the Rydons inside my pack. The bag doesn’t provide any crush protection, but prevents the lenses from getting scratched. I use the bag that came with my old Revision Sawfly optics.

I also carry a full-size microfiber cloth. This is the same large model I use to protect my laptop screen. It is slightly redundant with the microfiber bag – both can be used to clean the lenses – but I find the larger size of the dedicated cloth useful.

There’s enough room in the wallet to store my Cablz retention strap. I have kept this attached to the Rydons most of the time since purchasing the strap last year, but if I remove it, it goes in the wallet.

The wallet can fit a 5ml spray bottle filled with ROR. That’s not something I carry around on a daily basis, but I’d consider tossing it in for an extended trip.

As you may have gathered, one of my pet peeves is dirty optics. I want to protect my corneas from UV radiation and impact, but I also want vision that is high definition and high fidelity. The Rydons, coupled with this small and lightweight kit, support that objective.

Every Day Pliers

I carry Fix It Sticks for screwing and small Westcott scissors for snipping. Since learning about them last year on Jerking the Trigger, I’ve carried Knipex 87-00-100 Cobra Pliers for gripping. There are times when a classic multitool, like a Leatherman, is preferable, but I find this selection is more functional for most of my mobile tool needs.

I measure the baby Knipex pliers at an overall length of 103 millimeters and a mass of 60 grams. They are an excellent purchase.

A Better Kanteen Lid

My favorite lid for standard mouth Klean Kanteen bottles is the Topoko Straw Lid B. It’s a simple flip-top straw lid. The only thing that makes it special is that the mouthpiece is covered when closed. It seems like a common sense concept, but so many sport lids have no provision for some sort of mud guard.

Other than that, there’s not much to say about the lid. It is completely leak-proof when closed. It is easy to operate one handed. It comes with two straws that can be cut to length. One is stiff and the other is bendy. I’ve found no functional difference between the two.

I have these lids installed on both the bottles I use on a daily basis – the 27 oz that I carry on my bike, and the 40 oz I use at home.

I did break one of the lids by accidentally dropping the bottle from about 4 feet onto concrete. It broke where the carry loop connects to the base. The lid still sealed and functioned properly. I only use the loop for pulling the bottle out of a cage or pouch, but I still purchased a replacement (and another spare) immediately.

The new lids I received were slightly different from the old ones. The bit that covers the mouthpiece is clear instead of black, and the edge of it is flush with the edge of the lid. On the old model, the black cover was a couple millimeters proud of the edge of the lid, which provided more purchase when grabbing the piece to flip it open. The older design seems superior, but I haven’t actually noticed a practical disadvantage with the new one. I can still easily and reliably flip the lid open, even with a gloved finger. (That is, however, with light gloves – the older design may have more of an advantage with heavy winter gloves.)

I’ve only used the lids on Klean Kanteen bottles. I use these bottles for water. I don’t know if there are any special considerations that would make the lids less than ideal for hot beverages.

I’ve used every iteration of Klean Kanteen’s Sport Cap since I bought my first bottle from them in 2005. They’ve all left something to be desired. The Topoko lid is a superior solution.

Rema Rotation

I previously outlined my patch kit, which is based around Rema patches and vulcanizing cement. Ensuring the health of the vulcanizing cement is key to the functionality of the kit. As with any liquid adhesive, it can dry out in an open tube. Or the tube may sprout a leak, causing the liquid to leak out and vanish. I have taskwarrior tell me to replace the cement in my patch kit every 3 months:

$ task add due:2020-01-01 wait:due-3weeks tag:bike recur:quarterly replace rema vulcanizing cement

The task is really just a queue for me to evaluate the condition of the kit. Because I do not get flats often, there’s a good chance that the cement tube in my kit will be unopened when I perform this evaluation. If the tube is sealed and appears in good condition, I’ll leave it in without replacing it. If it is open, I remove it from the kit and replace it with a new tube. The old cement goes into my toolbox at home. When I apply a patch at home, I’ll first try one these old, retired cement tubes.

Before marking the task as complete, I’ll also evaluate the patches in the kit, replenishing or replacing from my bulk supplies as necessary.

This process gives me extreme confidence that my patch kit will be functional when I need it.

Cablz Eyewear Retention

I’ve previously mentioned my fondness for Rudy Rydon eyewear (particularly with the photochromic laser red lenses). One of the benefits of the Rydons is the adjustability of the temples and the nose pad, which allow for a secure, custom fit. This makes added retention via a strap unnecessary for securing the Rydons on the face, yet I’ve come to appreciate having a retainer attached simply because it allows me to drop the eyewear around my neck when I don’t need it. This offers more security than pushing them up onto the crown of my head or hanging them over the edge of my shirt or pocket, without requiring the hassle of putting them away in a pack.

For this application I’ve come to like the Cablz Zipz Adjustable Eyewear Retainer. I use the 12 inch version. These are made of a coated, stainless steel wire. When you’re wearing the eyewear, the wire sits up off the neck so you don’t feel the retainer at all. When you’re hanging it around your neck, it is thin and light enough that you soon forget it is there (this is also a result of the lightness of the Rydons, of course). The zip allows the length of the retainer to adjust from about 6 inches to 12 inches. At the smallest setting this keeps the Rydons tight on my face, but since that is not what I’m looking for I keep it adjusted about half way. At roughly 9 inches in length, I find that I can easily don and doff the eyewear, and that they sit at a comfortable position on my chest when I’m hanging them around my neck. The “universal” silicon ends of the retainer grab securely on the Rydon temples.

Cablz isn’t the only company to offer this style of retainer.

The Croakies ARC Endless is the same basic idea. I bought one to try out, but found it to be inferior. The silicon ends are significantly thicker and less comfortable behind the ear. I could bend the Rydon temples to account for this extra thickness, but I appreciate that the Cablz retainer requires no adjustment of the eyewear. With the Croakies, the pieces you grab to tighten the retainer are quite small. You’re adjusting the retainer blind by reaching behind your head, so the haptics are important. I found the Croakies difficult to use when wearing gloves. The Cablz adjustment pieces are large enough to be easy to use whether gloved or gloveless.

The equivalent from Chums is the Adjustable Orbiter. It only adjusts from 10 inches to 15.5 inches, which is too large for my needs, so I didn’t buy one to try.

I recommend the retainer from Cablz. It provides a simple but helpful augmentation to my eyeball protection system.
