The bench-top bandsaw is one of the most well-used power tools that we have in the Hackspace.
It is a Schneider model SCH190, with 250W motor running at 1500RPM.
So it is not a hugely powerful device - do try not to force it to cut too quickly, as the narrow blades (which are useful for curve-cutting) are easily worn-down and broken.
Replacement blades are 56½" long, and are available from Toolstation
76022 56½ x 1/4" 10tpi 44839 56½ x 1/4" 14tpi
Wider blades, for straight cutting, which may also fit (not tested) are: 12103 Bandsaw Blade 56½ x 3/8 6tpi 23015 Bandsaw Blade 56½ x 1/2 6tpi
Other suppliers may keep equivalent blades, for example Silverline brand: 633924 56½ x 1/4" 6tpi 868739 56½ x 1/4" 10tpi 675295 56½ x 1/4" 14tpi
