Used Speedy Forge Model F-512 Forge.
A modern designed forge, offered in 3 sizes to meet the requirements of the General Shop, Vocational and Agricultural School Shops, or, Blacksmith, Industrial, and Farm Maintenance Shops. The Flat Hearth Slot Forge is particularly adapted for tool dressing and sharpening, general forging, bending, and welding operations. Work is always visible to the operator, thus preventing burning and wasting of materials.

The forge is constructed of heavy gauge steel, structurally reinforced and electric welded. The reflector baffle is made of steel angle and bar to resist sagging and bending. The reflector elevating screw provides easy, positive adjustment. Like all Speedy Forge Furnaces, the complete firebox and hearth area is lined with High Alumina Fire Brick to give extra service life. High temperature castable insulation between the fire brick and the furnace shell provides faster heating, greater fuel efficiency, and simplifies the relining of the furnace. The reflector baffle lining is composed of standard 9 in. and 13 in. insulating fire bricks. An adjustable work support rack is also standard equipment.

The Gas/Air Mixer operates efficiently with either natural or propane fuel. The standard mixer is a two valve, manual control type which permits the operator to adjust the flame to any characteristics desired. Combustion Safeguard Systems with spark ignition and continual flame monitoring are standard equipment on all forging furnaces.
