Venmo1958 Bridgeport J-Head (step pulley) knee mill, serial J13223. 9x42 table, R8 spindle taper.
RUNS ON STANDARD 240V — no phase converter needed. Plug it in and go.
Semi-restored — all bearings in the head and spindle replaced with quality ABEC-7 precision bearing sets (~$900 in parts). Saddle hand-scraped flat using a calibrated surface plate. Table top flattened. Entire machine fully disassembled, cleaned, inspected, and reassembled. No rust or corrosion anywhere.
Upgraded with a 5 HP A.O. Smith 3-phase motor (huge upgrade over the stock 1 HP) and an Invertek OptiDrive E3 VFD that takes single-phase 240V input. Soft start, variable speed control, and overload protection.
What was NOT done (being upfront): Table ways show significant wear typical of a 1958 machine with decades of use — ways were not scraped or reground. No calibration/alignment performed. Quill feed handwheel is missing (cheap replacement part). No DRO, power feed, vise, or tooling included.
Great machine for a home shop — ready to make chips. Also a solid foundation if you want to finish the way scraping yourself.
Dealer-rebuilt Bridgeports go for $6K–$10K+. This is a lot of machine for the money.
On a pallet, ready to go. I can help load with a forklift — bring a trailer. Cash/Venmo/Zelle. Serious inquiries only.
