I started this over 15 years ago. It sat in the corner all cut, punched and unwelded. I just had to machine the ring to hold the jack and the ram holder for the bottom. I can change tooling in a second. I removed the u joints from a junkyard driveshaft to try it out in 5 minutes. Everyone that sees it wants one but i don't think i can compete with HF Tools. Those places weren't around when i started it...Bob
