Old World Wool Seal Making

Today Peter created new bearing seals for the 1934 Lagonda M45 Rapide. The seals of the day did much the same job as today’s plastic over steel equivalent. The main sealing surface is wool felt that, soaked in oil, does a good job holding most of the oil and grease in place. The tools of the trade are pretty simple ones: a spoon, a ball-peen hammer, scissors and a razor blade. The thick wool felt is traced and cut via razor blade.

To make the wool a bit “proud” – to stick out like the chin of a duke – paper gasket material can be cut and built up behind the wool. A spoon and a ball-peen hammer are all that is needed to make an imprint to cut out.

This twenties automotive seal technology was used in agricultural equipment for decades such as wheel seals on an Oliver or Cockshut tractor.

    Dear sir/madam,
    The Lagonda above is in fact a 1936 LG 45 Rapide. I knew the car well and often drove it when David Dunn of Dublin owned and restored it form its lowered state. I still have the lowered rad and the original exhaust manifold that Terry Cohn replaced. It’s a 10ft 9 inch chassis but the previous ’35 M45′s were 10ft 3 inch wheel base. The last time I saw the car here at the ards TT it had extra lights fitted, spare wheel incorrectly side mounted, stickers all over it, all the dashboard switches moved to non original locations etc. but I still loved her. Best of luck with her .
    Regards,
    Eddie Bourke, Dublin Ireland.
