VACUUM FOR CAST IRON DUST
To help with the cast iron dust when boring, I’ve made a couple different collectors. Vacuum cleaners work, but are so noisy you can’t hear the machine. This last one I built,with the large air filter is by far the best one. Made from an old squirrel cage fan, some dryer duct, some scrap tubing and a little silicon sealer.
