Firearm or Gun Safety Rules Mug

I'm teaching my family some firearm safety and wanted something with the "four rules" on it. I didn't find anything I liked, so I made my own Firearm Safety Rules coffee mug.
I'm not a big graphics expert or anything, but I made a simple logo and rewrote "the gun safety rules" as I like them. And a bit of work online and poof I had a mug!
Here are some pics:


There are some famous sets of safety rules out there, I rewrote them as I preferred and came up with this:
Firearm Safety Rules
1. Always handle all firearms as if they are loaded.
2. Never point a gun at anything you are not willing to destroy.
3. Keep your finger off the trigger unless your gun is aimed at the target.
4. Positively identify your target, backstop and that the line of fire is clear.

If you would like one of these you can get one here:

Gas Spring Strut repair for Hammerhead 42" Toolbox from Costco


The gas spring struts that hold the lid open on my stainless steel Hammerhead 42" Toolbox (model 2002-1800) from Costco just failed. Sadly, they leaked oil in the top compartment of the box, making a mess and melting the drawer liner. A big mess.

Amazingly I have the old toolbox manual and it lists the replacement as part number TB12U06. But I suspect I'm out of the warranty period.

The original struts measured:
eye to eye:   extended: 350mm (13.8"),     compressed 220mm (8.7")
stroke: 130mm (5.1")
10mm ball receptacle

I measured the force it took to compress one of the old ones on a bathroom scale. Of course it had been leaking so maybe it was a bit low. It seemed to take 15-20 lbs to compress it.

Removing the old struts just require lifting the metal band up a bit with a screwdriver and then the head pops off the ball.

I scoured the Internet and it seems gas spring struts like these are available, but the lowest force ones I found were 24 pounds each! The lid on my toolbox isn't that heavy, but I decided to try them: Suspa 24 LB Gas Spring C16-06389. About $30 for a pair on Amazon. (See addendum at the bottom for a better strut option!)

Here is a pic of the old and new strut. The new one is on the bottom and you can see it is just a bit longer.


Installing the new strut requires you lift the band on the head just a bit with a screwdriver so the head can pop on the ball.

Here is a shot of the new strut installed:

And here is the strut in action. You can see it is a bit too strong, the lid really flies open!


If you can find them, I instead recommend struts rated for around 15 pounds each.

Addendum: As recommended in the comments, I tried some different 10 pound struts from liftsupportsdepot.com. The struts I bought were part number SX140P10. These are also available through Amazon here. I have installed these, and I much prefer how the lid now opens in a much more controlled manner. I suspect a 15 pound struts would be perfect, but these 10 pound ones are much better than the 24 pound ones I started with. Get the 10 pound struts if you can't find 15 pound ones.

KTM Sidestand Spring Bolt

Twice I have lost the bolt that holds my side stand up on the KTM! Thankfully the KTM has a backup rubber band to hold the side stand up.
It is a silly design where the spring bracket probably helps to turn the bolt loose as it vibrates up and down.
The second time I had to buy one of these I was careful to clean it and use loctite blue to hold it in place. An as an extra precaution I marked it with some paint so I could see if it started to loosen.
And look at this, a mere couple hundred dirt miles later and it's coming out!

I can't believe it!

OK, now loctite red. It's too much for a little bolt but I can't stand losing this thing again.
