A large volume TPC will be used in the near future in a variety of experiments including T2K. 
The bulk Micromegas detector for this TPC is built using a novel production technique particularly 
suited for compact and robust low mass detectors. The capability to pave a large surface with a 
simple mounting solution and small dead space between modules is of particular interest for these 
applications. We have built several large bulk Micromegas detectors (27x26~cm$^2$) and we have 
tested them in the former HARP field cage setup with a magnetic field. Cosmic ray data have been 
acquired in a variety of experimental conditions. Good detector performances and space point 
resolution have been achieved.
