Has anyone had experience with these?

CA Applicator Extender Tips
SKU# BA-301 Edit $1.99 $1.99

I need something to apply pin point applications of CA in closed wing structures. CA is great but not if it goes where you don't want it. These might by worth a try.

For Bob Smith Industries glue bottles?

If so, these are a better tip Dave. Extra long, for a long reach and so you can just cut the end if it glues shut. Nice fine tip for 1 drop out. 6 per package instead of five and a dime cheaper. Easy to see the glue creeping towards the tip as you add pressure to the bottle. Have used these before with great success. I usually pick up two or three bags and they last quite awhile.

Keith:

Sadly, Bob Smith Industries (BSI) uses a proprietorial bottle and cap and I have bunch of Hobbico CA that I'd like to use up before I convert.

I'd better check if the tips at Brodak fit my Hobbico CA containers.

Hmmmmm......... But, yes, the BSI tips look to be just the ticket I'm looking for.

Thank you for the suggestion/recommendation.

This is what I use:

I use the .015 and .022 ID tubing. PTFE is Teflon and CA will not stick to it --- you can chip it off with your fingernail if so inclined. I just make a hole in the end of the spout large enough for a friction fit of the tubing (cutting the end of the tubing at an angle makes for easy insertion). Normally, I use about 1.5" of tubing. At the end of a building session, the spout and tubing goes into a tub of acetone (tupperware tubs with a screw-on top work great) and any remaining CA is dissolved. Cap the CA with an uncut spout for storage.

With a little care and practice, you can squeeze a tiny drop out for applying or use capillary action to run a continuous bead along a joint. Either way, it reduces the amount being applied.

At $0.16/ft., twenty feet of tubing is cheap and will last for a long, long time, especially if reused (the acetone soak has no effect on it).
