Whats a needle gun

[Jordan Baker]

Hi everyone.

I was reading in one of my old mags about a chap from England that restored the Churchill Crocodile. In the article he mentionds that he had used a needle gun to clean up the parts instead of sand blasting.

Could someone tell me what exactly this tool is and what it does.

Would it be worth the expense to get one for my carrier restoration. Right now Im using a couple of brass wire wheels in an electric drill to clean up the small parts. However this wont really be practicle when doing the larger pieces.

Sincerely
Jordan Baker
