    Paint bungs

    Hi All,

    Following on from my painting hangers I thought I would share how I prevent paint getting into bores. I find it hard enough to coat components at the best of times so this is a very annoying part of painting/spraying in stopping paint getting in places you don’t want it. Masking holes I also find difficult.

    One day I had loads of holes that needed to be masked so paint didn’t get in. A few weeks before I had been to a car boot sale (garage sell) and bought a wine/beer making kit, which I only wanted the bucket with the lid to house my pickling solution for silver soldering. Amongst the kit was some rubber corks which fitted a treat in the holes. As this was successful I have since acquired several different size corks as can be seen from the photo. The second photo shows the hub of a capstan wheel from my ring roller I am currently building using the corks to block the holes I don’t want the paint to cover.

    I hope this will be helpful to anyone who has had this issue and if anyone has any other good masking techniques I would be very keen to learn more.

    Natural or poly corks are used by many industries, and are available through many sources. But the most I've seen are used in painting, and re-usable many times. The poly type are more tapered, small as 1/16", hence more diameter range.
    In lieu of stoppers, I've had decent performance from rolled news print, with top crimped.
    ...we'll learn more by wandering than searching...

    I save those plastic plugs from every plumbing, hydraulic fitting, or replacement part I buy. I have several coffee cans full of them. Probably the most indispensable throw away item ever invented. I use them and reuse them over and over and cringe when ever I see someone step on one that has fallen to the ground. A customer thought I was nuts when I told him to take care removing them and to save them instead of tossing them in the trash until he tried to return a very expensive valve he bought that had the wrong porting and spool configuration the supplier wanted to charge him over a $1000.00 dollars. He said I'll be back in a couple of hours. rummaged through my stash and found some new looking identical plugs went back traded out the valve only a $25.00 restock fee. Now a believer for life, and I am no longer the nutty guy who saves plugs from the trash.
