Actuator and Jack screws also. On June 1, 1951 two partners, Frank Nelson and Glenn Simpson, opened Precision Screw Thread for business.   They had been turned down on a business loan by a commercial bank so Frank took a mortgage on his house to provide the operating capital.   Glenn brought his entrepreneurial vision and a willingness to work for limited compensation. This embryonic entity struggled to establish itself in the first year with Glenn working at other jobs at night for a paycheck while he ran PST during the day.   In a little over a year, the day to day operation of the company changed from a solo effort when the first non-owner employee was hired on August 1, 1952.   The first employee was a woman who had previous experience operating thread-rolling machines.   She stayed with the company until her retirement in 1967. Late in the third year of operation PST found itself struggling with a cash-crunch.   Glenn found it necessary to go his father and borrow additional operating money.   While the senior Simpson was not very fond of the idea, he did come up with the funds necessary to see the company through the tough time.   It obviously worked because by 1954 a second employee was added to the company.   This man remained on the staff of PST until his death due to cancer in 1981. The mid fifties were a turning point for PST.   Now even Glenn was on the regular payroll of the company.   And there was enough financial depth for the purchase of a brand new "Grob" thread rolling machine.   Along with this acquisition came a new relationship with Theodore (Ted) Grob Sr. It was more the relationship, than the machine, that was to change the course of PST in the years to come. The '50's saw the company grow from a local job shop to a job shop for the Northeastern United States.   Although the process of thread rolling was not widely accepted by engineers of that era, the people of PST slowly chipped away at the attitude, gaining acceptance in a wider and wider market almost daily.   The growth was great enough to require that the company relocate to larger facilities on South 31st Street from its original converted storefront operation on Kinnickinnic Avenue, in Milwaukee, Wisconsin. PST's relocated a third time in 1961.   Again the move was due to growth and success, which called for more space.   This move took PST to a brand new building in the Greendale Industrial Park.   After ten years in business the company was strongly established and poised for additional growth in its new facility.   This positioning was fortuitous because that relationship that was started in 1955 with Mr. Grob was about to turn into a real watershed point for PST. As it turns out Mr. Grob owned a company that really had three distinct business units, new machine importing and sales, tooling fabrication for the machines and contract manufacturing using the machines and tooling to make custom parts.   Mr. Grob decided that he wanted to concentrate on machine sales and tooling and wanted to divest his firm of the contract business.   He made Glenn a deal that could not be refused.   And although the acquisition was a stretch, the opportunity was too great to pass up.   A deal was agreed to! To prepare the company for this purchase PST was incorporated in the State of Wisconsin on December 14, 1962.   The new corporation closed on the acquisition within a matter of days of incorporating.   Equipment was moved before the first of the year from Grafton, Wisconsin to Greendale.   But as in earlier acquisitions of machines it was to be a "people" component that would out shine any hard asset's value. A man by the name of Leonard Barth was running the contract side of Mr. Grob's business at the time of acquisition.   Len agreed to become the Plant Superintendent for PST.   His passion for thread rolling matched Glenn's.   Len brought an element of professional expertise that was greatly needed by the company.   With Len now being part of the team, PST was able to restructure the business to give more emphasis to customer service.   Len saw to it that the manufacturing side was prepared to meet the new growth that the sales side of the business could now foster.   Len taught and nurtured dozens of PST novices through out his career.   Many of these same people are still with PST today. By the mid 60's the company was well enough established to create profit sharing/retirement trust.   It was in the mid 60's through the 70's that many of the people who are in leadership rolls today started with the company.   In 1970 an apprenticeship program was started that was to graduate 13 Journey Machinists in the next three decades.    Also the mid 70's found PST venturing out into a new area of business manufacturing ball screws in affiliation with Rockford Ball Screw Company.   RBS's founder, Ian McBain quickly guided the company to huge success as he marketed and sold the product line.   This new affiliation with RBS was to help keep PST on its long established growth path. It was a growth path that required additional floor space for manufacturing operations.   So, a specifically designed building was erected in the Muskego Industrial Park.   The building and its expansion were both funded by Industrial Revenue Bonds, which the City of Muskego sponsored. In the 80's PST expanded into new directions by offering services such as turning, grinding and machining.   This allowed the company to provide complete parts to customers as opposed to only thread rolling services.   This ability also positioned the company to enter into the aerospace business, which is a large portion of the sales enjoyed in the new millennium. In 2001, as the company celebrated its 50th year in business, PST found itself to be a team of employees who operate a profitable and diversified company.
