Modding A Powdercoating Gun For Performance

In life, tools come in two varieties – good tools, and cheap tools. This is where the hacker steps in, to transform a cheap tool into more than the sum of its parts. [Josh] had problems with his Eastwood powdercoating gun. [Josh] decided to fix things with a couple of tasteful mods.

The problem with the gun was related to the delivery of powder to the workpiece. The stream was either too weak to coat properly, or too heavy, delivering a thick stream of powder. [Josh] surmised that with better airflow into the powder reservoir, the gun would deliver a properly mixed cloud of powder as required. By drilling a couple of small holes into the air feed into the reservoir, the powder stream was much less heavy and the gun’s performance was greatly improved.

[Josh] then decided to take things a step further, by fitting a tip from a more expensive gun to his Eastwood model. There were some challenges in getting it connected electrically, but nothing a little electrical tape couldn’t fix. While this did further improve results, it was a minor improvement compared to the air feed modifications.

Overall, [Josh] was able to take a poorly performing tool and transform it into something much more useful, just by drilling a couple of holes. Check out our Hacklet on quick tool hacks, or share your best work in the comments.
