1 rich Libsyn https://www.libsyn.com 90 600 Jason Marburger of Fireball Tool returns for our annual conversation — and he's not pulling punches. We dig into the public feud between Fireball, Sigmund, and Quantum Machinery over fixture table claims, why &quot;world's strongest welding table&quot; needs data to back it up, and Jason's push to standardize testing across the industry. He also walks us through the grinding disc performance guide his shop spent months producing, the surprising winners (the $2.50 Steel Savage, the new 3M Cubitron 3), and why pressure — not RPM — is what most welders are getting wrong. Plus a preview of what Fireball is rolling out at FabTech Vegas, including a 1,800-pound blacksmith vise, theft-proof service truck vises, and the new Mystic Square.
