OK, so I'm retired and have a lot of time on my hands - and I enjoy every minute of it!!
I am somewhat new to DIY mixing, and found my clumsy self almost knocking over these little bottles and spilling some expensive liquid.
So, I started digging around my junk boxes to make a few tools:
This one is just a spray can top with a center plastic cup that keeps the bottle from being "easily" knocked over.
Here, I got a little more creative:
I used an old wall switch cover and glued 3 rubber "crutch tips" on it. These are also sold to put on stool feet to minimize floor scratches. This is the second version where I used 2 small and 1 medium rubber tip.
Along the same line, I was worried about spilling my large bottle of premixed base 50/50-1.2%:
I sliced a large rubber tip in half and screw/glued each side to a small piece of plywood. It works, but the board could be slightly larger.
Now for the main mixing station I got creative. I used several size tips and a larger board. Epoxy did not hold, so I resorted to screws inside each tip to secure each bottle holder.
This main unit sits inside a "cafeteria tray" in case I do have a spill.
And, here is my stash of flavors. This seems to grow a little larger each week...Thanks to Wizard Labs and the postman.
