New machines are made for 'table top' use. The newer tables have a 'push down' apparatus to 'hide' the machine and some machines have a hole in the bottom so you can screw your machine down to the 'table' in these new cabinets. Does yours have a screw hole in the base? If so you could have someone make a wooden base that attaches to the "L" brackets and then you could screw your machine into that base. Also, there should be a wooden type 'sling' under the hole where the machine swings up from. This is suppose to protect your machine from falling to the floor and to help with dust accumulation.
Clear as mud?
Good luck!
