HÖGBO Lathe
Early Hogbo Lathe   Hogbo Milling Machine


Manufactured by a Swedish company, Högboholms Mek. Verkstad 340 37 Torpsbruk, the Högbo Model 75 lathe was based on the American Atlas 6-inch (though with a longer bed and, on later versions, with the addition of a front bed V-way for the saddle) Unlike the American model, the Högbo used plain instead of roller bearings for the headstock and was, in that respect, identical in specification to the cheaper version of the Atlas offered by the mail-order company Sears under their Craftsman brand. However, instead of simple plain bushes, nipped into adjustment by a split headstock sleeve, the Högbo employed rather more substantial bearings that, being threaded on their ends, could be drawn down into tapered seats by opposed adjustment rings. With the expectation of sales running into the hundreds of thousands, Atlas had invested heavily in expensive moulds to produce many larger and smaller components - including the changewheels, backgears and leadscrew clasp nuts - in pressure-injected ZAMAK, a form of hard-wearing zinc.. Surprisingly, Högbo, despite having a smaller and less-affluent market to sell into, also chose the same material for some minor parts, though major items, including all the gears, were made from conventionally materials.
At first a standard bench-mount model with rear countershaft was offered, followed by one on a rather fine pressed-steel underdrive cabinet stand complete with tall, cast-iron raiser blocks the headstock end one of which was used to mount the electrical reversing switch.
Based on the examples discovered so far the lathe appears to have been originally painted in a bright red enamel.
If any reader has a Högbo lathe the writer would be interested to hear from you.
