Improving all your spray bottles

[cshamilton]

I mentioned a glass bead and a brass hose barb. You'll be find. Plus, lots of spray bottles have a tiny bob inside to control the spray flow.

Screw Iphone and it's ridiculous auto correct.

How about fishing weights?

Not a bad idea, I think lead is non-reactive with most chemicals... any chemists here who can give us a little insight?

I modified a few bottles so far and it works well. In a few of them I removed the plastic straw completelly and plugged the tube directly in. In some none of the tubes I purchased would fit exactly the hole so I did the mod like described in the video.

What tubing did you use

Just plastic tubing I purchased at Home Depot. I got 3 sizes of it so that I could fit any bottle. Fitting the stainless steel nuts it the most complicated aspect. Pretty hard to find nuts that will fit the tubing perfectly.

So what I did is I found nuts that fitted the largest tube I had, and I use electric tape to make it fit on the smaller tubes.

In terms of efficiency, the smaller tubes are better. The large one is pretty stiff and it needs a little help to move around in the bottle even with the weights on it. The small one moves easilly when the weights are attached.

I'd suggest using a "clunk" and silicon fuel line used for R/C heli applications. Prior to recently getting back to my car addiction I spend several years flying Nitro R/C Helicopters. Clunks are used in the fuel tank to pickup fuel at any angle (see video at the bottom of this post )
