Hi my name is Steven I'm a refrigeration engineer with my dad ran own business for 10 plus years . We've made a hydraulic pipe bender that can bend 1.3/8 and 1.5/8 pipe with ease and the tool is small and easy to use . Also hoping we can bend 2.1/8 pipe to just on with that . I'm thinking of patenting the idea would just like some feedback if any one has used hydraulic pipe benders or think there's a market for the tool because don't think it would cost to much to make. Any input would be appreciated thanks
