I bought some syringe and fine needles without the cuting bit. You can fine them for grease and adhesives. With a inside hole of a 0.7mm and exterior of 0.9mm, they work great. I insert them and flush IPA directly from the inside.
I tested finer ones, 0.15mm/0.3mm (inside/outside) and is very difficult to push the alcohol through them,
The ones I use: https://es.rs-online.com/web/p/agujas-dispensadoras/4003895?gb=a
I second the syringes work great make sure to flush the tips and clean them afterwards really good as I have a few i let sit and the resin cured
I’m a big fan of the chonky syringes, you can add different diameter tips to control pressure/flow rate and don’t have to refill as often. This one is a bit overkill but gets the job done.
“a bit overkill” yeah it can just hold half a cartridge of resin ^^
lol wow that thing is huge
using some hypodermic injection needles with 30G or smaller could also help you to manually rinse the very fine dead end holes.
