Nozzle for filling small holes ?

[Boo2]

Hi,

I've been using Loctite Hysol 9462 for filling small holes left by fasteners, mostly because it is supplied with mixing nozzles (see pic below) that have rather small ends that will poke down into the holes but also because it is strong and (somewhat) non-sag. It is, however, also ruinously expensive and I wondered if anyone knows an alternative type of nozzles or another way of poking epoxy filler mix down to the bottom of screw sized holes in the 6-10mm range ? I have tried poking it down with a stick in the past but it is a bit unsatisfactory as you never know how much air you've put in.

Many thanks,

Boo2

How about some cheap small syringes from ebay or similar? Fill them with whatever you want - mixed epoxy?

I use disposable plastic pipettes like we used to have in Chemistry at school. The nozzles are very small, and you can trim them off for a wider one if you want.

What's the best way to fill them with epoxy? Suck it up or pour it in with the plunger removed?

Sucking it up works fine. I used to use syringes before I thought of pipettes.

It looks from the pics like they have a bulb at the top to suck in and expel the liquid. Is that right?

I think when I was at school they hadn't invented disposable plastic. I seem to remember pipettes being glass tubes, one end of which had a narrow nozzle, the other end of which was plain and you put a thumb over it to control when and how much liquid you were releasing (or am I confusing them with something else?).

Yep, that's right. Works much like a syringe, except the nozzle is narrower so you can generally fill screw holes without leaving a big air bubble, and they're a lot cheaper for single-use.

I think those were also pipettes. I'm sure I've seen them with a removable rubber bulb (like an old car horn) slipped over the top for sucking and blowing, but I guess that was optional.

At school we didn't regard the plastic ones as disposable, but they definitely are when used with epoxy or gelcoat!

They had those at my school. In those pre- H & S days you simply put the lower end in the chemical and sucked on the other end. There was a bulb half way down which was supposed to slow things down so preventing sucking the chemical into your mouth. I remember our class being delighted when an unpopular chemistry teacher sucked some acid into his mouth.

We were also allowed to use lathes and other machine tools at school. We were taught boxing as well. Amazingly, we all survived into adulthood.

Same here. I would hope they still do (or at least, where they don't it's because they don't have the machines rather than because of Elfin Safety).

We also had an area for oxy-acetylene welding; usually the teacher would do the actual welding after we had clamped the parts in position, but where someone's project involved a lot of welding he would give them a quick demo and then leave them to it, rather than tie up all his time.
