I never used an Oliver, only seen them a long long time ago. The old timer that sold me his Serrano in 1968 also had an Oliver. I never really paid that much attention to it. He also had an old machine and had had no tension mechanism, but had a large wooden dowel. He said when he was very young , he learned to wrap string around a wooden dowel, and pull tension by hand, and place an awl into the hole to maintain tension.I didn't doubt him. Said he could pull any tension asked for with accuracy, as that was all that was available when he was young. This was in 1968 and he was an old timer back then.He sold me that Serrano and taught me to string. I brought my racquet, a Tad Davis, and he told me I might as well use the string I hit with to string it, that was Victor Imperial Gut. I strung it up with him next to me, when done he said I should be able to string any string out there after that. He also taught me a knot to use, said no one he knew used that knot and it would distinguish my work from anyone else . That knot is now called the so called Parnell knot I was on my own after that time. No internet, videos, USRSA, or nice sites like this one. Just learned tips and tricks along the way.Hard to believe that was 52 years ago!
