Disposable syringes with thin cannulas for placing liquids

[Andreas Thaler]

I was looking for syringes with thin needles for dispensing small amounts of alcohol, oil and benzine on Amazon.

For just under EUR/USD 12 you can get 30 disposable plastic syringes with needles and a volume of 1 millilitre.

Country of origin: China.

The selection on Amazon is huge.

Out here in the Wild West, it's easy to get a wide variety of syringes at veterinarian supply stores -- and support local businesses.

Perhaps the best thing about Vet shops is that they have a good supply of BIG, THICK needles (for BIG animals). This makes thicker liquids (Rapid fix, etc.) easier to handle -- and they have JUMBO-sized syringes (sizes you would never use on a human!!!).

Always take a file to the tip of the needle before using -- to flatten it out. After all, they are designed to pierce skin VERY easily -- and they will if you are not careful.

I found oils and various thinners like alcohol, acetone etc can swell or soften the rubber so I use the glass ones.

For my use, I buy from Amazon "art & craft syringes" that have blunt tips instead of sharp tips. This way I can avoid stabbing myself, while still get small enough droplets (1ml).

Yes, you have to be careful, so I only use it for a short time and then throw it away.

I also have a set of oilers in different sizes for applying small amounts of oil. To do this, simply dip the tip in a little oil.

Here it is used on the mirror box of the Nikon F4.

I like those!

Is this the mechanism that stops the aperture lever at the correct place?

I can't say, but it's plausible with the sprocket. The infamous wheel turns a photointerruptor (the black wheel with recesses behind it).

The beam of light that is interrupted sits like a fork underneath. It can be seen in the photo.

And these plastic foam sticks can even withstand acetone for a short time, in my experience.

Ideal for cleaning, I use them in large quantities.

Also available in a wide selection on Amazon.

You may have seen in another thread I have a N75 that looks un-used with a fault in that area. I'm still trying to figure out how it works for there may be a way to repair it. For example, why would a late model camera that looks un-used have a fault? It is a $9 camera, so I'm more interested in figuring out how it works.

How do you go about troubleshooting?

I has been written that there is an electro magnet that instantly stops the aperture lever at the correct location. Apparently this can fail.
I also collect and repair electric guitars. The guitar pickup is like an electromagnet but for sensing only. Anyway, there are no moving parts, almost always failure is because the fine wire wrapped around the steel core is broken somewhere. These can even be re-wound.

Another possibility the electromagnet is too far away (broken plastic or glue). I'll check for that too.

If all of that is OK then there may be an optical sensor, so I'd like to check that.

Not just liquids. I use one --medium size tube, flat tip-- for Teflon grease. Minute quantities dispensed just where needed. The piece of clear tubing serves as a protective cover.

I just fixed it. It indeed was a cold solder joint leading to the aperture control mechanism!

Great!

And until now I thought that such soldering was always perfect.

This gives me hope for my F3AF, whose display no longer shows reasonable values.

Tutorial Nikon F3(AF): Replacing the LCD

On the Nikon F3 and its versions, the LCD that is reflected in the viewfinder can fail partially or completely. Corrosion of the LCD connections could be a cause, or the LCD sandwich no longer seals tightly; black spots can also appear that make the digits unreadable. The only solution here is...

Looks like "Swiss oilers" for watchmakers.

Buy full sets of four probes, the job will thank you by being that much easier to complete.

Avoid any probes with burrs and lose fibers.

Cheers.
